Arnold & Porter Kaye Scholer LLP

Arnold & Porter’s patent litigation team has been on a superb run of form in recent years, which speaks to the talent of its trial lawyers and the quality of the support and resources they have to draw on. It is entrusted with significant cases of critical importance to the parties involved – and with good reason, as it has individuals such as Deborah Fishman and Michael Berta on deck. Silicon Valley-based Fishman is in her element in complex life sciences suits and has lately been serving as lead counsel defending two of Regeneron’s patents protecting blockbuster drug Eylea against an ex parte re-examination challenge. In this, she is acting alongside brilliant prosecutor, counsellor and post-grant lawyer David Marsh from the DC office in a great example of the solid teamwork in which the firm’s practitioners constantly engage. Berta has continued to perform flawlessly for Google and recently scored a comprehensive victory for the internet giant in a case implicating Google Maps and Waze-related technologies. Arnold & Porter also excels on commercial IP briefs, many of which land on Thomas Magnani’s desk in San Francisco. “Tom’s skills as a technology transactions lawyer are virtually unparalleled – he is practical, innovative and business minded.” His trailblazing clients include Fullpower Technologies, which is at the forefront of AI biosensing; Magnani has supported the company in connection with numerous strategic partnerships, including with NIKE.

Baker Botts LLP

Courtesy of its first-time inclusion on the prosecution table, Baker Botts earns expanded coverage in the California rankings of the IAM Patent 1000 for 2021; once again featured on the litigation list, it presents a well-rounded patent practice on the West Coast, just as it does nationally. Focusing on the prosecution and counselling side reveals a dynamic practice that is relied on by numerous well-known technology names from areas such as social media and ride sharing. Palo Alto attorneys Hogene Choi and Travis Thomas are essential partners to Lyft, whose Level 5 Engineering Centre they assist with the development of the company’s autonomous driving systems and networks patent portfolio. Choi co-chairs the firmwide prosecution group and debuts in the rankings this year; also a gifted team and project manager, Thomas makes his return. They have a new colleague down the hall in ace counsellor Christopher Palermo, who joined from Hickman Palermo Becker Bingham in 2020 in a move that will considerably enhance the firm’s profile in Silicon Valley – Palermo’s stomping ground for nearly three decades. High-profile assignments are the order of the day for the local litigators, including eminent trial lawyer Hopkins Guy and Palo Alto IP chair Eliot Williams. Together, they secured a great result for DISH Network at the Federal Circuit, which ruled that configuring a computer to implement an improvement to an abstract concept is not patent eligible.

Bozicevic Field & Francis LLP

Bozicevic Field & Francis has “an unrivalled reputation for expertise in biotechnology patent prosecution”. Keeping pace with – indeed, often setting the pace for – innovators at the cutting edge of the life sciences, start-up guru Karl Bozicevic and strategic patent counsellor par excellence Carol Francis burn brightly.

Cooley LLP

Adept in all areas of patent practice – from prosecution and counselling to litigation and transactions – and active globally from bases in the United States and Europe, Cooley sees the whole playing field for clients and can offer incredibly valuable strategic and commercial guidance as a result. This is warmly appreciated by tech juggernauts such as Facebook, which consistently engages “top patent trial lawyer” Heidi Keefe for its most significant court cases and PTAB proceedings; and by marquee pharmaceutical and biotechnology entities, which call upon seasoned litigator and biochemistry and biophysics PhD Michelle Rhyu. The life sciences is another bastion of strength for Cooley’s elite transactional lawyers, such as Marya Postner, who captains the industry-focused partnering practice. Postner’s recent highlights include advising clinical-stage biotechnology company Sangamo Therapeutics on its global collaboration with Novartis to develop and commercialise gene regulation therapies. Mika Reiner Mayer is one of the firm’s best-rounded operatives: she’s an ace on patent and IP due diligence – she recently supported Vaxcyte in connection with its June 2020 flotation – and on prosecution and counselling.

Davis Polk & Wardwell LLP

Forming a dynamic strike force for prestigious clients, the trial lawyers at Davis Polk & Wardwell are a discerning choice of patent litigation counsel in commercially consequential cases when only a win will do. The practice is headed up by Ashok Ramani, an American College of Trial Lawyers fellow who has gone the distance for a litany of household-name technology companies and met with striking success on both sides of the ‘v’. His fellow partners in Northern California are David Lisson and Micah Block, each of whom – like Ramani – is superb on the strategic planning and oral presentation aspects of his craft. According to peers, they make for an “exceptional team that never goes through the motions, but is trial ready from day one”. They are the go-tos for Comcast, which they are currently representing in numerous patent cases initiated by Rovi Corporation (now part of Xperi); and recently acted for Cisco Systems against Centripetal Networks in the first federal bench trial conducted entirely by video.

Dentons

In California, Dentons has assembled quite the line-up of all-star patent prosecutors – and one which has helped to considerably elevate what was already an outstanding national patent team comprised of more than 100 lawyers and advisers in 19 offices. Zooming out, Dentons has over 600 IP and technology lawyers worldwide, giving clients easy access to a cavernous chest of resources. The leading lights on the West Coast include Peter Yim, who provides staunch leadership to a team of 20-plus practitioners spanning multiple bureaux both within and outside California. Yim is a repository of trust for some of the biggest and most exciting emerging names in technology, which seek to capitalise on his blend of prosecution, patent strategy, post-grant proceedings and litigation expertise, along with his international view and experience. Brian Ho – the co-head of the US IP and technology group – is similarly versatile and also someone who inspires and motivates as a leader. Yim and Ho link up with savvy global patent portfolio builder Randy Omid and Christopher Eide, whose bailiwick encompasses just about all areas of innovation in Silicon Valley, to form a uniquely strong core of patent protectors.  Head to Southern California and the firm’s San Diego office brings Stephanie Seidman into view: she is enlisted by life sciences entities seeking the best in the drafting, filing and registration of patents that are sufficiently robust to form the foundation of business-critical licensing and partnering deals. Special mention should also be made of Dentons’ post-grant practice, which is supervised by Kevin Greenleaf, a Silicon Valley-based technically trained computer engineer who has made a major contribution to the firm’s astonishing track record of success for petitioners and patent owners.

Desmarais LLP 

When it comes to high-stakes patent litigation, New York outfit Desmarais is hard to beat. Capable of taking on the toughest suits involving the widest range of subject matter, its trial lawyers make all the right plays while offering flexible and innovative fee arrangements specced to fit the needs of those they represent. The ensemble’s stature in California has increased considerably thanks to the efforts of San Francisco lawyers Peter C Magic and Ameet A Modi. Alongside national superstar John Desmarais, they have recently been defending Verizon against patent infringement claims made by Huawei relating to network infrastructure and internet and wireless communication technology; and defending Apple in a suit filed by nCap Licensing. Both Magic and Modi can be counted on for smart strategic calls in the preparation phase of litigation, as well as for resonant performances at trial. They were recently joined by former Ropes & Gray partner Gabrielle Higgins, a career patent litigator and trial lawyer with vast PTAB experience.

DLA Piper

Nothing is off limits in patent practice for DLA Piper, which has highly trained and experienced patent prosecutors, litigators and transactional lawyers on deck. For the 2021 edition of the IAM Patent 1000, the global outfit has a new face in the rankings in Erin Gibson, a “thorough, collaborative litigator with great ideas” and a veteran of many ITC investigations and district court trials. She is based in San Diego; as is Sean Cunningham, also a dyed-in-the-wool advocate with plenty of jury trial and ITC wins under his belt. Mark Fowler is another name for the address book for those in need of a seasoned litigator; as global IP and technology group co-leader, he is well placed to tap into DLA’s deep resources for the benefit of his clients. While these practitioners keep the focus on high technology, alongside Silicon Valley corporate securities and IP licensing specialist Mark Radcliffe, life sciences entities aren’t left out in the cold: they have Lisa Haile to call on as one of DLA Piper’s most technically adept and well-rounded patent counsellors.

Durie Tangri LLP

There’s no question about Durie Tangri’s consummate ability to strategise, fight and win bet-the-farm patent litigations: constantly in the thick of the action for Silicon Valley’s high-technology and pharmaceutical players, its lawyers have honed their trial skills to the sharpest point – and none more so than leader Daralyn Durie. “As good as it gets”, she is an “even-keeled, well-organised lawyer who can roll with the changes while remaining focused and on top of everything”. In a patent infringement suit that will shape the market for targeted therapies to treat metastatic melanoma, she is currently representing Berkeley-based Plexxikon against Novartis – a good example of the industry-impactful matters that she routinely takes on. She has also represented Genentech and City of Hope in disputes with various companies seeking to market biosimilar versions of Avastin and Herceptin, Genentech’s blockbuster oncology drugs. At the forefront of the practice – and the market – alongside Durie is Mark Lemley, whose appellate expertise cannot be bested. He recently represented the plaintiffs in Staley v Gilead Sciences, Inc, a dispute which has raised uniquely complex issues at the intersection of antitrust and patent law whose resolution will potentially change the law regarding generic suppression in the pharmaceutical industry. Durie and Lemley couldn’t take such mandates on without great support, and they have it in spades from a cadre of up-and-coming stars including Adam Brausa, Kira Davis (a new addition from Paul Weiss), Tim Saulsbury and Eugene Novikov.

Fenwick & West LLP

Cutting-edge high-technology and life sciences innovation is the lifeblood of Fenwick & West, a Silicon Valley outfit that has played a key role in the ascent of many companies to market dominance. Strength in depth across the contentious/non-contentious divide distinguishes it as one of the nation’s premier one-stop shops for patent services – as reflected in the inclusion of multiple individuals on each of the prosecution, litigation and transactions tables. In terms of recent developments, the set has doubled down on its longstanding efforts to enhance efficiencies and reduce costs; the deployment of online filing technologies and proprietary databases that, for example, enable painless competitive intelligence gathering has been especially impactful for precision prosecutors such as Rajiv Patel, who continue to work miracles. IP chair Patel is peerless when it comes to advising early-stage companies on patent portfolio development and setting them on the optimal path for business success; he has concentrations of clients in areas such as cybersecurity, artificial intelligence (AI), big data and bitcoin mining. Also in a position of leadership, patent chair Michael Farn helps set the pace for this high-flying group and instils it with the commercial mindset that he has wholeheartedly adopted throughout his career. Farn likes to get hands on, making him well suited to particularly complex and mission-critical patent assignments. Undertaking matters of a similar nature for Facebook, meanwhile, are Robert Hulse and Antonia Sequeira, who continue to file and manage a substantial portion of its patents, including those protecting some of its most important product areas; both attorneys excel at building portfolios from the ground up. They are also adept at handling utility and design patents, which is also true of several others in this galaxy of stars, including John McNelis, Jae Won Song, Brian Hoffman and David Ahn. A former patent group chair and managing partner who has cultivated a high-level strategic view of intellectual property and its role in commercial life, McNelis has distinguished himself as a leader in the area of autonomous transportation. Song’s USP is his ambidexterity as a patent counsellor and litigator; while Hoffman brings sophisticated data privacy expertise to the mix. Ahn – who also supports the Facebook relationship – is a “consistently thoughtful strategist with a unique ability to place himself in the position of his clients and grasp their key priorities so as to enable ideal business decision making”. Doctor of medicine Daniel Becker is a go-to for cutting-edge biotechnology innovators such as Corvidia Therapeutics, for which he has drafted and prosecuted next-generation patent families and supported it through its 2020 acquisition by Novo Nordisk.  Speaking of deal work in the life sciences brings Jake Handy, a favourite of early-stage biotechnology companies, into the discussion; he chairs the technology transactions group –an essential component of the wider IP practice – and has an affinity for innovative deal structuring and IP value creation. He represents Veracyte, a leading genomics diagnostic company, and recently handled its exclusive licence agreement with Yale University to advance the first genomic test for predicting disease progression in patents with idiopathic pulmonary fibrosis. Co-leader of the life sciences and health technology industry group Stefano Quintini also weaves exciting new partnerships and collaborations with a magic touch in areas where disruptive technologies are transforming drug discovery and development and medical care. He recently advised Exicure – a pioneer in gene regulatory and immunotherapeutic drugs using spherical nucleic acid technology to deliver drugs – on a global collaboration, option and licensing agreement with Allergan Pharmaceuticals, which aims to discover novel treatments for hair loss disorders. In the internet, networking, cybersecurity, social media and other technology spaces, Ralph Pais is an M&A master at Fenwick, thanks to recent highlights such as representing ThousandEyes in its acquisition by Cisco, which was said to be valued at around the $1 billion mark. Stephen Gillespie also regularly leads IP diligence and negotiation teams in M&A scenarios for prestigious clients such as Amazon and Symantec. Completing the IAM Patent 1000 transactions line-up, David Hayes capitalises on his broad IP vision – he is a USPTO-registered patent attorney who has worked on many and various infringement matters – to sew up lasting deals.  Turning to the contentious side, Fenwick’s litigators frequently collaborate with their colleagues in other practice areas to ensure that disputes strategies are mapped out with perfect exactitude. Just as in prosecution and transactions, the bench is a deep one: the firm has six lawyers recommended for litigation in the guide, which is the joint second-highest in California. The top name on the fight card is Michael Sacksteder, who is currently leading a large cross-office team – across San Francisco, Mountain View, Seattle and New York – defending Supercell in 11 patent infringement suits brought by GREE asserting 30 videogame patents and involving a great number of PTAB actions; a favourable verdict on damages was secured in the first trial, which took place in September 2020. Bryan Kohm, who is acting alongside Sacksteder on this matter, plays a key role in the firm as chief specialist in the ITC, where is he is currently representing Lashify in a patent enforcement campaign against manufacturers, distributors and resellers of copycat versions of its iconic false eyelashes, with Saina Shamilov as his co-lead. Shamilov has a reputation for excellence spanning all patent litigation forums, which stems from her proficiency in navigating large, procedurally complex disputes and resolving them successfully. She and David Hadden have been dealing with one such suit recently for a major technology company and dozens of its customers. Hadden is distinguished by his combination of trial and technical skill; so too Charlene Morrow, whose knowledge of case developments and vision on the future path of the law add tremendous value. Stuart Meyer is one of the firm’s pre-eminent post-grant minds, which is impressive considering the level of PTAB expertise that his litigation colleagues have built up. Integral to the launch of internal post-grant database and patent eligibility tools, Meyer goes above and beyond the brief to furnish clients with the patent knowledge they need.

Fish & Richardson

Judged purely on the strength of its trial lawyer contingent in California, Fish would be a potent force in patent litigation; but, being similarly stacked in key locations across the country, it is close to untouchable. San Diego alone is home to Juanita Brooks, Jonathan Singer, Chad Shear, Seth Sproul and Roger Denning – all of whom are legal lions. Brooks is a talismanic star of the practice with an illustrious reputation. Second to none in terms of advocacy skill, she continues to shine in the high-technology, medtech and life sciences spaces. Recent highlights include defending biotechnology leader Illumina in a case filed by The Scripps Institute regarding technological tools for genomic testing. Singer captains the life sciences litigation practice and ranks among the pharmaceutical world’s foremost trial attorneys. He and Shear continued their Herculean efforts for Gilead Sciences in its hard-fought battle with Idenix Pharmaceuticals in 2020 with a Federal Circuit appearance that resulted in the denial of Idenix’s bid to reinstate a $2.5 billion verdict it had previously secured, but then lost as a result of Singer and Shear’s successful bid to wipe it out; we’re talking ‘best trial lawyers in the world’-type stuff here. One of the firm’s most technically adept practitioners, Sproul has been at the vanguard of developments in the 5G space; his cases have also involved complex FRAND issues. Denning has spearheaded trials in patent litigation hotspots around the country, including the ITC, where he is now representing Intuitive Surgical against Ethicon Endo-Surgery in a dispute whose outcome which will significantly impact on the robotically controlled surgical technology market. There are guiding lights in Silicon Valley, too, with David Barkan, Michael Headley and Betty Chen all springing to mind. Barkan is hailed as an “elite IP litigator with profound knowledge of the law, but above all strategic vision”. The dominant storyline in Headley’s recent practice was a fierce battle for Power Integrations against Fairchild Semiconductor, which is all closed off now with a $175 million settlement for his client. Chen makes her debut in the IAM Patent 1000 this year in recognition of the leadership she has shown for the likes of Microsoft and other blue-chips. She also serves the firm as global hiring principal. No less integral than their contentious counterparts to Fish’s overall patent practice are counselling and prosecution aces Hans Troesch and Eric Schulman. Troesch founded the Silicon Valley office in the early 1990s and has since assisted a rainbow of established industry leaders, solo inventors, start-ups and academic and research institutions with the creation and management of patent assets. Schulman can transform companies’ IP programmes with new and innovative strategies – something that he has done both in-house and in private practice.

Gibson Dunn & Crutcher LLP

When multinationals need to litigate with maximum impact for maximum gain, they call in Gibson Dunn & Crutcher. The trial lawyers here make for formidable adversaries in the courtroom, though a lot of their appeal from the client perspective derives from their proficiency and aggressiveness in pursuing earlier-stage wins. Whatever the best strategy is for any individual case, Wayne Barsky, Josh Krevitt, Jason Lo, William Rooklidge and Kenneth Parker will identify and develop it from the moment of filing through trial and beyond. Barsky’s legendary feats include defending EMD Serono and Pfizer in a long-running dispute against Biogen, which sought damages of $5.4 billion; in September 2020, the Federal Circuit reinstated a jury verdict that the asserted claims of Biogen’s patent were invalid as anticipated, and reversed the district court’s post-trial order granting Biogen judgment as a matter of law and a conditional new trial. This is one of the biggest defence victories ever in a patent infringement suit, and Barsky has effectively won it twice. Krevitt provided invaluable support in this effort; while Barsky has likewise supported Krevitt in his ITC litigation for Fitbit against Philips, which is just one of many important litigations on which he is leading. There are no sharp elbows here and nobody worries about who is running point – all the lawyers work collaboratively in trial teams configured according to the needs of the case and client. Cross-office integration also sees the likes of Lo link up with colleagues in New York, DC and Texas – as he has done recently in representing SoundCloud and other clients. Rooklidge has several long-term patrons which he continues to support through thick and thin. Parker is a new arrival, having switched from Haynes and Boone in August 2020, and brings extensive ITC experience to the group. Gibson Dunn also made additions to its sterling transactional practice in 2020, hiring Karen Spindler from Goodwin Procter. The sophisticated life science deal lawyer has been acting for Sage Therapeutics in its $1.525 billion global collaboration and licence agreement with Biogen to develop and commercialise potential breakthrough therapies in depression and movement disorders. Carrie LeRoy draws on insight gained as a former in-house senior licensing professional in co-chairing the technology transactions group.

Goodwin Procter LLP

Goodwin Procter has assembled an indomitable patent group in California with the self-sufficiency to support clients in all patent endeavours: it is home to broad-minded strategists, fearsome litigators and transactional specialists whose collective industry coverage is comprehensive. A good place to start on the counselling and deal side is with PhDs Michael Shuster and Kevin Kabler who, together with Sarah Solomon, take centre stage in Goodwin’s life sciences group. Often teaming up, Shuster and Kabler provide the right type of support at every stage of the business lifecycle, showcasing refined sector knowledge in their analysis and evaluation of third-party patents for risk mitigation and investment purposes. Coming in for special praise, Shuster is “the definition of a creative and skilful partner. He and his team use the most current technological resources to provide an excellent and – critical for small companies – cost-effective service. Michael is exceedingly responsive and is available for calls early in the morning to late in the evening, even though he’s in such incredibly high demand”. More of a pure-play transactions attorney, Solomon is always engaged in topical matters and is the lead Goodwin lawyer advising long-time firm client Moderna Therapeutics in connection with its proprietary mRNA-based covid-19 vaccine candidate. Sanjeet Dutta keeps it real in high-technology areas such as software, autonomous driving, fintech and telecommunications; clients frequently consolidate their entire portfolios with him, given the quality he offers. On the contentious side, Neel Chatterjee, Darryl Woo and Brett Schuman land big hits in competitor tussles and other strategically and commercially important scraps. Chatterjee can be found by the side of blue-chips such as Facebook and in hot technology areas such as streaming and interactive media; in this latter field, for example, he is acting for eko (Interlude.fm) in a high-profile patent infringement, trade secret and breach of implied contract dispute. “Neel has an amazing grasp of technology and speaks the language of patents, but can also translate it for those who don’t. You can leave major litigations in his capable handles without having to micromanage the work being done – he tells you what you need to know and then litigates beautifully.” Integral to the eko litigation alongside Chatterjee and another go-to for Facebook, Woo is a tried-and-tested trial lawyer who can’t be fazed. Schuman is engaged in a sprawling 24-patent dispute filed by TQ Delta against client CommScope-owned 2Wire, in the course of which he has successfully defeated several of TQ Delta’s patent assertions before trial. The former head of litigation for Goodwin in California marshals resources effectively for large matters and shows superb leadership.

Greenberg Traurig LLP

Looking at Greenberg Traurig (GT) through a wide-angle lens reveals a muscular patent and IP litigation set-up with talented trial lawyers in locations around the country. Zooming in on San Francisco and Silicon Valley reveals a similar picture of strength, considering everything that locals Nicholas Brown, David Bloch and Scott Oliver bring to the practice. Brown furnishes the group with abundant trial skill, which he has refined in district courts and the ITC. His recent activities have included extensive post-grant proceedings work on behalf of Satco Products as part of a cross-office Denver, New Jersey, New York, San Francisco and Virginia team; GT has always been highly effective at uniting different lawyers under a common cause. Given his Winston & Strawn pedigree, Bloch also knows his way around the courtroom. Teaming up with Scott Bornstein in New York and Vivian Kuo in DC, he is currently acting for specialty tobacco products company Kretek International and others in a multi-forum ITC, Central District of California and Western District of Kentucky patent and trade secret litigation. Technical chops and specialist knowledge of patent pools and standards give Oliver his edge, especially in licensing disputes. Andrew Schwaab anchors the Northern California prosecution team, which has put in place vital IP protections for ShotSpotter, a pioneer in the field of gunshot detection technology to which US cities are increasingly turning to prevent and reduce gun violence.

Haynes and Boone LLP

Haynes and Boone has suffered some attrition in California, but its reputation as a preferred destination for prosecution and strategic counselling support remains undimmed; if anything, the recent effort put in by Orange County-based Tom Chen on behalf of innovators such as Lyft and Qualcomm has only elevated its status. Chen syncs well with engineers and in-house attorneys, and has a fine appreciation of companies’ technologies, legal needs and wider objectives; he leaves no stone unturned to protect his clients in the United States and internationally and help them move their business forward. Greg Michelson – a key member of the Lyft team – takes the lead in handling wide-ranging prosecution, licensing, risk assessment and counselling assignments for Peloton Interactive and FLIR Systems, a world leader in thermal imaging cameras, components and sensors. Nationally, Haynes and Boone is a premier prosecution firm according to a number of measures, including volume of applications filed, allowance rate and time to allowance.

Irell & Manella LLP

Irell & Manella practises at the apex of the patent litigation market; there’s no clearer evidence of this than its March 2021 $2.2 billion jury trial win for VLSI Technology against Intel in the Western District of Texas. This was masterminded by Morgan Chu, Benjamin Hattenbach and Alan Heinrich, who deserve all the props they get for this result – and for the consistency with which they have won big cases throughout their careers. Other impressive results of late have included a $506.2 million damages win for PanOptis in a patent suit against Apple involving 4G Long-Term Evolution (LTE) technology; central to this was Jason Sheasby, who has plenty of large monetary awards on his résumé. In April 2021, the firm welcomed former USPTO director Andrei Iancu back into the fold.

Jones Day

A prime destination for technology and IP-intensive transactions, Jones Day makes full use of its global network and deep institutional knowledge to sew up major cross-border deals with the greatest of ease. This is what Thomas Briggs – a founder of the firm’s specialised practice in this area – has been doing for much of his private practice career. Leaning on the litigation and prosecution expertise he has cultivated along the way, as well as experience as a company chief IP officer, he brings a multi-faceted perspective to the negotiating table. Jones Day is always high on the list for litigation, particularly among pharmaceutical companies, which turn to IP group leader Anthony Insogna as well as East Coast specialists such as John Normile. Insogna is a high-level strategist who has won huge patent infringement verdicts and safeguarded many billion-dollar drugs. Trade secret litigation is another string to the firm’s bow, which has an authority on the subject – and an excellent trial lawyer – in Randy Kay.

Kasowitz Benson Torres LLP

Tried and true in the courtroom, Kasowitz has gained the admiration of many of the world’s top technology companies as they navigate critical patent issues, as both patent holders and accused infringers. The team is a diverse and cosmopolitan one, but its members have a lot in common, including technical aptitude, toughness and calmness under pressure. Exemplifying these and many other attributes, Jonathan Waldrop provides strong leadership to the IP litigation group. He, Darcy Jones and Marcus Barber form a formidable team that puts its shoulder to the wheel for the likes of Google: they are representing the internet titan in an action brought by Eolas Technologies, which alleges infringement of a patent covering methods that enable internet uses to interact with online video, music and audio clips and other browser-embedded features. They have also been putting in the hours for ASUS in multiple cases and for Reddit, among many other prestigious clients. These three lawyers never let anyone down – not least because of the passion they pour into their work.

Keker, Van Nest & Peters LLP

Keker, Van Nest & Peters needs no introduction as one of the best litigation outfits in the United States. Famous for its memorable courtroom performances, it applies exceptional rigour and keen strategic vision throughout all phases of a case, putting it in pole position for a trial win if necessary, but also giving it an edge in negotiations. Its patent litigators – including Robert Van Nest, David Silbert and Matthias Kamber – are always in the frame when infringement suits threaten the core business of the parties involved, which are typically dominant forces in technology.

Kilpatrick Townsend & Stockton LLP

Undertaking a prodigious volume of analysis, opinion and prosecution work, Kilpatrick Townsend is at the pinnacle of the patent counselling profession. Its substantial, richly resourced group is fluent in all areas of science and engineering, but overlays its technical and legal knowledge with a strategic and commercial approach that yields handsome benefits for clients. Electronics and software group co-leader Craig Largent, for example, has impeccable technical credentials and is a former practising scientist with his name on multiple patents; having partnered closely with start-ups and established companies in Silicon Valley for so long, he has cultivated an intuitive appreciation of the role that intangible assets play in driving business. He is protecting breakthrough graphene technology for the California Institute of Technology, and doing so internationally through an extended network of foreign contacts. Sujit Kotwal – who previously held the role that Largent now occupies – has a similar approach to portfolio building: the actions he takes are calibrated to generate valuable commercial opportunities. Another high-technology ace, William Shaffer has extensive contentious experience and so understands how patents can be attacked; this knowledge feeds into prosecution strategies that are designed to minimise future risk. Medical device maven Nena Bains has previously worked in-house and so sees things through clients’ eyes. A one-stop shop for patent services, Kilpatrick Townsend also handles litigation instructions with alacrity: its top advocates – many of whom have technical backgrounds themselves – draw on support from their prosecution colleagues to cut through the densest cases. Broader engagement in patent practice by trial lawyers such as Megan Chung further helps to integrate the firm’s various offerings. Chung has sharp transactional skills; as does James Isbester, who deploys his licensing expertise to help clients avoid costly litigation. Both lawyers – who jointly represent a leading scientific instrumentation company – can also bring the heat when necessary. So too can Steven Moore, who had a busy 2020 litigating for Japanese gaming and internet media company GREE in a major battle with Finnish mobile game developer Supercell; at trial in September, he obtained a verdict of wilful infringement and a damages award for GREE.

King & Spalding LLP

Significant growth in patent litigation is the central thread of King & Spalding’s recent IP narrative: the firm has added 12 specialised partners in the past two years and has invested in building out the teams around them with associates, counsel and technical specialists. Considering this expansion, and in view of the calibre of its trial lawyers, it is now a force to be reckoned with in district court and ITC litigation, Federal Circuit appeals and post-grant proceedings. One recent addition is Shane Brun, who has served as lead counsel for marquee names in patent and other IP disputes for more than two decades. A former in-house counsel, he takes a pragmatic approach to conflicts and prioritises the achievement of commercial aims. He joins fellow Silicon Valley-based lawyers Thomas Friel and Jim Brogan – two trial heavyweights who, true to form, have recently been putting in a superb showing in a complex and hard-fought competitor dispute regarding automotive emission technologies.

Kirkland & Ellis LLP

Kirkland & Ellis manifests a rare faculty for patent litigation and has a multitude of experienced and strong-willed trial lawyers who are relentless in their pursuit of clients’ commercial objectives. They always plan for trial, as this puts them in the strongest strategic position whichever way a case turns; but the focus is firmly on resolving disputes, as opposed to just fighting them. The leading lights in California are Luke Dauchot, Michael De Vries, Adam Alper and Ellisen Shelton Turner. Dauchot has litigated – and tried – a wide variety of commercial, IP and other cases, giving him an encyclopaedia of attack plans to choose from. De Vries and Alper recently secured their 2019 $125 million jury verdict for EagleView Technologies in a competitor case against Xactware Solutions and Verisk Analytics regarding aerial imaging technology after vigorous post-trial briefing in September 2020, in which the district court roundly rejected and denied the defendant’s request to reverse the verdict and declare a new trial. In support of lead partners Greg Arovas and Todd Friedman from the New York office, they and Turner are also representing Intel in litigation against Swiss patent licensing company PACT XPP Schweiz; the case is progressing, with Intel having successfully motioned to add claims of inequitable conduct for each of the 12 asserted patents and having filed inter partes review petitions challenging the validity of the asserted patents, 10 of which were instituted.

Knobbe Martens

Patent and IP powerhouse Knobbe Martens is virtually unsurpassed for prosecution, counselling and post-grant depth in the life sciences. Armed with PhDs in various relevant subjects, Salima Merani, Kimberly Miller, Eric Furman, Joseph Reisman, Kerry Taylor and Eli Loots all possess special attributes that put them in hot demand. A seasoned portfolio builder who can pinpoint IP value, Merani is the go-to diligence and deal lawyer for medical technology and biotechnology investors. Playing the trusted adviser role to perfection, Miller shows impressive range as an all-IP counsellor and problem solver. Furman likewise has broad horizons, engaging in patent procurement, opinion work and licensing; the ambidextrous Reisman affords a lot of options through his proficiency in prosecuting and enforcing patents; and Taylor and Loots have well-developed post-grant skills that put them in the thick of the action at the PTAB. Other names to keep on the radar include Daniel Altman, Jason Jardine and Michael Fuller, who also have much to commend them. Altman is the first choice for international protection, particularly in Japan, China and other Asian markets; Jardine is appreciated for the creativity with which he pursues the registration of applications that have got stuck in the system under other counsel; and biotechnology practice leader Fuller excels at the confluence of life sciences and computer technology, and of law and business. The medical device industry is another notable stronghold for the firm: it has a leading specialist in Gerard von Hoffmann, who has served on multiple company boards. On the high-technology side, John King and Adeel Akhtar pave the way. Chair of the patent prosecution committee King is the first choice of start-ups for prosecuting foundational patents. A 21-year partner at the firm and the leader of its San Francisco office, Akhtar makes light work of complex software, data processing and electronic technologies, and is also a reference for semiconductors. Knobbe Martens’ litigation offering is equally as sophisticated and well stocked with standout talent. The best known is Joseph Re, who has led trial teams to landmark victories backed up on appeal: “He has an amazing ability to connect with juries and a passion for his craft.” Joseph Cianfrani chairs the litigation group, in which he instils a business goal-oriented approach. John Sganga is guided by a strong sense of justice and gives his all for clients; while Jon Gurka litigates across the IP spectrum with poise and purpose. A polished advocate, negotiator and IP strategist, Irfan Lateef makes the most of all available tools to deliver success.

Kobre & Kim

Making its debut in the IAM Patent 1000 this year, disputes and investigations specialist Kobre & Kim garners enthusiastic recommendations: “The firm takes a streamlined approach to patent litigation and makes things happen fast – there’s no red tape like at larger competitors. Its lawyers are highly intelligent, driven, strategically focused and creative, constantly coming up with great ideas and new initiatives to better help their clients.” Playing a starring role in the practice, Michael Ng is “calm, thoughtful, open-minded in terms of solutions and an exceptional litigator all round”. He also “thoroughly understands the nuances of the litigation funding world and knows it better then anyone”. He and Daniel Zaheer “go up against the biggest firms and win substantial cases with lean teams”.

Latham & Watkins LLP

Latham & Watkins is abundantly rich in IP trial talent – 20 of its leading litigators in the United States make the IAM Patent 1000 for 2021. Some of the best of them – Douglas Lumish, Jeffrey Homrig, Richard Frenkel and Julie Holloway – can be found in the Silicon Valley and San Francisco offices, their launch pads for major competitor campaigns on behalf of technology world leaders. All four lead trial contingents in which practitioners from across the network collaborate willingly and enthusiastically – teamwork is baked into the model. Heading the fight card is Lumish, a habitual winner whose trial verdicts and non-trial resolutions are always satisfying to business leaders. The secret of Homrig’s success lies in his ability to make the abstruse accessible to juries and triers of fact. Engineering experience elevates Frenkel as a fine technical lawyer. Holloway also has a technical background (electrical engineering), which she combines with sparkling advocacy skills that she once put to the test in a remarkable four trials in one year. Latham is also an eminent transactions firm and has supremely capable lawyers in Judith Hasko and Anthony Klein, who oversee lucrative life sciences and high-technology deals respectively.

Lowenstein Sandler LLP

Lowenstein Sandler may not be a household name on the West Coast, but those in the know recognise it as an ideal fit for patent preparation and prosecution, portfolio building and IP commercialisation. These are the primary activities of Marina Portnova, who chairs the software and electronics practice within the patent counselling and prosecution group. She represents Google in protecting technologies relating to YouTube and GSuite; assists Lashify with US and international filing and pre-litigation strategy; and undertakes key assignments for a leader in autonomous driving. Kevin Grange, meanwhile, puts in the safeguards that keep a major technology company’s R&D team focused on innovating. Grange is primarily based in Utah, where he oversees the firm’s dedicated patent prosecution centre, but he stays close to all the goings-on in Silicon Valley.

Mayer Brown

“Mayer Brown’s Palo Alto team is exceptional on patent litigation, business consulting and licensing. Edward Johnson and his team deliver a best-in-class work product in terms of the briefs, motions and other materials generated in the course of litigation. Ward is also brilliant in depositions and excels in the courtroom.” Another source adds: “Ward is a uniquely skilled adviser – he has deep knowledge of black-letter law, coupled with a pragmatic approach and an invaluable ability to think outside the box.” He represents Gemalto, a worldwide leader in digital authentication, in multiple matters; and acts for LED lighting company Lumileds jointly with Michael Molano, the IP practice leading and hiring partner for Mayer Brown’s Northern California offices, and a seasoned district court and ITC litigator.

McDermott Will & Emery

The life sciences is a happy hunting ground for McDermott Will & Emery, as senior company figures observe: “Its agents and attorneys have strong technical backgrounds (many hold PhDs) and notable patent drafting, prosecution and litigation skills – a combination which is not easy to find.” Valued for its end-to-end services, the Silicon Valley team comes recommended for its “superior quality”. PhD Judy Mohr covers a huge amount of ground given her mastery of US and international prosecution, post-grant proceedings, IP due diligence, deal negotiation and strategic counselling. She frequently collaborates with litigation colleagues William Gaede and Bhanu Sadasivan – for example, on behalf of Heron Therapeutics, a NASDAQ-listed public company that provides technology solutions for the delivery of pharmaceuticals. Gaede is, first and foremost, a true-blue lead trial counsel; but he also “understands how changes in patent law potentially impact the life sciences industry”, making him an effective counsellor. He has been integral to jury trial wins for Amgen against Sanofi and Regeneron over drugs that lower bad cholesterol; as has Sadasivan, who makes her debut in the IAM Patent 1000 this year. “Bhanu draws on her experience as a litigator and her deep scientific background to provide astute guidance that addresses client needs directly. She is extremely intelligent and produces top-notch work in a timely, cost-effective fashion.”

Milbank LLP

Many high-exposure, high-impact life sciences and technology patent litigations bear Milbank’s fingerprints: for example, the firm was at the forefront of some of the first lawsuits to be filed under the Biologics Price Competition and Innovation Act and, more importantly, achieved fantastic results for clients Genentech and Biogen. Primarily responsible for these, David Gindler is a celebrated name in the biotechnology space. CEOs call him an “extraordinarily gifted lawyer with a commanding presence”, adding that “he inspires confidence as a counsellor who addresses complex legal and business issues in a practical manner, and as a trial lawyer in vital cases”. Away from the life sciences, he is acting for China-based Rosenberger Asia Pacific, the third-largest base station antenna manufacturer in the world, in defending a suit filed by US company CommScope, which is the second-largest – a representation in which Milbank’s global presence, Hong Kong office and US-based Chinese-speaking litigators all confer a major advantage. With Gindler on this is Gary Frischling, another litigator of great stature. Joining them in the listings this year, Lauren Drake is a rising star who is taking on increasingly significant roles, working alongside Gindler, Frischling and New York éminence grise Errol Taylor.

Mintz

When it comes to building patent portfolios and developing and implementing strategies that maximise their value, Mintz is world class. Life sciences innovators know this well, given their experience with William Kezer and Terri Shieh-Newton, who fly the firm’s flag high in San Francisco. They jointly represent Arcus Biosciences – Kezer handling its small molecule patents and serving as lead strategist, and Shieh-Newton taking on responsibility for its biologics patents. Both practitioners understand all that goes into protecting and strengthening clients’ competitive market standing, as well as what investors are looking for in a portfolio. To the latter point, Kezer’s recent work for Arcus included due diligence in connection with a nearly $2 billion investment by Gilead Sciences – a deal to which a portfolio handled by Shieh-Newton for an anti-TIGIT antibody was central. Kenneth Jenkins is another star of the practice with a fine appreciation for the scientific and business aspects of his craft. He represents a prestigious university, a leading cancer treatment centre and several corporate clients. Jenkins is based in San Diego, down the hall from patent prosecution and counselling chair Fred Hernandez, a touchstone lawyer for medical device and medical technology entities. The regularity with which industry leaders snap up the emerging companies whose portfolios he has developed is a telling measure of his quality.

Morgan, Lewis & Bockius LLP

“Morgan Lewis has a seemingly endless reserve of high-quality partners and associates to address any need. If you have a significant matter that you cannot afford to lose, it is the firm to turn to – you’ll have the best and brightest working on your behalf.” One of those is patent trial lawyer Michael Lyons: “Mike dives into the technical and other details of his cases and can cross-examine expert witnesses on very obscure concepts in a way that juries can follow and understand. He makes himself utterly and completely available to his clients, and is a trusted adviser and outstanding counsellor on the substance and strategy of cases – he tells it like it is and won’t sugar coat things just so they are easier to hear.” The Silicon Valley litigation practice leader added significantly to his résumé with a major victory for the Alfred E Mann Foundation for Scientific Research against Cochlear in a long-running patent infringement case; in March 2020, the Federal Circuit denied Cochlear’s petition for rehearing, cementing Lyons’s trial win and netting a payment of almost $280 million for his client. San Francisco’s Brent Hawkins – the group’s other elite West Coast IP litigator – is currently representing Zebra Technologies, a global leader in asset tracking technology. It is rare to find a firm that litigates at such a high level while also engaging in extensive and sophisticated patent prosecution and counselling work, as well as IP and technology transactions – but Morgan Lewis knocks it out of the park in all areas. Gary Williams, Mark Itri and Dion Bregman link up to advise a dominant global technology company and prosecute patents protecting many of its key technologies, from user interfaces to AI. Software maven Williams prosecutes with unbelievable precision, leveraging experience and technical fluency; while Itri is a seasoned strategist with a broad IP view. Bregman stands out for his post-grant proficiency, which he demonstrated recently in winning three inter partes reviews for One World Technologies. In two, the PTAB found all claims of the patent owner, Chamberlain Group, to be invalid for obviousness; and in the third, the claims were found to be unpatentable. These decisions follow a hotly contended ITC action that was ultimately resolved with a finding that One World Technologies’ redesigned products did not violate any ITC orders. Jeffry Mann and Nathan Smith offer the same exquisite level of service as their high-technology colleagues, but focus predominantly on pharmaceutical and biotechnology innovation. They excel at giving commercial impetus to portfolios and ringfencing clients’ most strategic IP assets. Rahul Kapoor’s name resonates in Silicon Valley, where he is considered among the very best deal lawyers – he is a towering figure at Morgan Lewis, as he is in the wider market.

Morrison & Foerster LLP

A technology transactions heavyweight, Morrison & Foerster (MoFo) has 50 dedicated specialists across its US, Asian and European offices, and is thus first port of call for the sorts of global deals that cause seismic shifts in industry, as well as for cutting-edge patent and IP commercialisation more generally. The practice is chaired by Aaron Rubin, an authority on social media, online business, software and many other technology subjects. He represents a top social media company with San Francisco colleagues Rufus Pichler and William Schwartz, both of whom operate at the vanguard of business dealings in technology and intellectual property. Pichler’s practice – not workload – has been significantly impacted by covid-19: he has been supporting a leading private foundation on pandemic-related matters such as the funding of vaccine development and assisting a technology leader in setting up testing labs. When something vital is needed quickly, Pichler answers the call. Speaking of industry shifts, he has also been advising a multinational conglomerate on a multibillion-dollar company sale that will create a major AI player. The transactions wing of the firm derives much strength – particularly in terms of technical and scientific support – from its connectedness with MoFo’s wider IP practice, much credit for which goes to Schwartz and his role in co-founding the IP group. His broad engagement – and the versatility of Tessa Schwartz and Paul Jahn, who counsel on patent matters as well as negotiating deals – further cement the link between the two groups. Drilling into the wider IP offering brings an outstanding life sciences practice to the surface, which is captained globally by Michael Ward, one of the world’s foremost plant and agriculture IP lawyers. Biotechnology and pharmaceutical companies have another vital ally in Catherine Polizzi, who unerringly prosecutes applications to successful grant while custom-fitting portfolios to serve commercial ends. There’s a deep bench of litigators, too, so when things kick off, MoFo can sort them out: with advocates of the stature of Michael Jacobs on board, the firm is a smart choice for the most business-critical suits. This is why streaming start-up Quibi has instructed Jacobs to put a hard stop to threats from a key rival.  Stefani Shanberg, Richard Hung, Matthew Chivvis and Jack Londen are all sure bets for do-or-die trials.

Nicholson De Vos Webster & Elliott LLP 

At the heart of happenings in Silicon Valley, agile boutique Nicholson De Vos Webster & Elliott prosecutes patents, manages portfolios, advocates at the PTAB and provides essential litigation support – all with technical precision and strategic flair. A notable development for the ensemble in 2020 was the recruitment of Judith Szepesi, an experienced patent attorney and a perfect match for the firm, with her emphasis on harnessing intellectual property for business gain. This is likewise the special skill of Daniel M De Vos, whose prizewinning patents have been successfully enforced through litigation, netting his clients handsome gains. He acts for a colourful catalogue of start-ups, mid-sized companies and Fortune 100s, and gets right to the crux of their commercial issues. His co-founder David Nicholson sees the whole playing field for the parties he represents, including pioneers in computer science and software.

O’Melveny & Myers LLP

Senior figures in blue-chip companies call O’Melveny & Myers a “pre-eminent firm for US patent litigation”. With numerous seasoned first-chair trial lawyers on deck, it makes light work of high-stakes cases and has an enviable hit rate. Notable recent highlights for the group include prevailing for Samsung against Image Processing Technologies in a six-patent dispute involving dozens of Samsung products using various camera functions. In this, Ryan Yagura and his colleagues instituted inter partes review proceedings to review the validity of most of the asserted claims; obtained a favourable claim construction ruling that invalidated several claims as indefinite; secured a motion to invalidate another claim under Section 101; stayed the district court litigation; won the post-grant proceedings, leaving just one claim standing; and then settled the case on favourable terms on the eve of trial. Never less than formidable, Yagura is a “star lawyer who you can trust with vital matters in district courts and the ITC. He cares deeply about his clients and is always ready to help with the most complicated of matters. He resolves issues promptly and efficiently, showing exceptional legal judgement and a sophisticated understanding of the business world.” Also attracting rave reviews is Luann Simmons, a former software developer who serves as regional head of litigation for Northern California. She brought home a series of victories against Barbaro Technologies on behalf of Niantic in a case involving its Pokémon Go game, ultimately resulting in a complete defence win. Co-leading on this and with Yagura on the Samsung brief, Darin Snyder also brings both trial skill and leadership to the table; he’s a past chair of the IP and technology group and currently serves as co-head of diversity and inclusion. The group’s successes invariably involve impressive displays of teamwork: in a recent defence of Google against Location Based Services, Simmons, Snyder and David Almeling partnered up to great effect. Almeling is chiefly known as one of the country’s best trade secret litigators, but he has patent law down cold too. One of the most practised lawyers in the fold, Brett Williamson is also at the height of his powers; he is currently leading Hulu’s defence in an infringement action against Sound View Innovations, which is being represented by patent litigation outfit Desmarais.

Orrick Herrington & Sutcliffe LLP

When it comes to high-stakes patent litigation and technology-intensive commercial disputes, Orrick doesn’t disappoint. Its experienced attorneys manage multi-faceted cases with impressive organisation and efficiency, and utilise finely honed trial skills to press their strategic advantage in negotiations and in courtroom clashes. The firm’s global IP group is chaired by Jared Bobrow, a patent and trade secret litigator who has spent decades on the frontlines of major battles involving cutting-edge technology. He forms a tailor-made strike force for prestigious clients with Clement Roberts, a determined advocate for whom there’s not such thing as a dead end: with his powers of persuasion and creativity, he always finds a way through.

Paul Hastings LLP

Paul Hastings presents to the market a highly accomplished patent litigation group. The California contingent alone packs enough firepower for the largest and most complex suits; factor in the talent in New York, DC and Chicago, and you’re looking at one of the country’s elite. The quality and experience of its leading lights in each locale are vital factors in the ensemble’s success: practitioners of the calibre of Yar Chaikovsky, for example, are rare to find. Charismatic global IP group co-chair Chaikovsky is a dynamite trial lawyer who never lacks for a convincing story to tell. When it comes to gutting a plaintiff’s damages theory, challenging validity on Section 101 grounds and drawing lines in the sand, he does it all brilliantly. Other go-to lawyers in Palo Alto include Philip Ou and Chris Kennerly, two redoubtable leaders whose work not just at trial, but throughout all stages of a case is top drawer. Together with Chaikovsky and Elizabeth Brann, they undertake extensive litigation and post-grant proceedings for Samsung, for which they often have multiple cases on the go at any one time. Kennerly and Brann defended the chaebol, for example, in a patent infringement case brought by International Technologies and Systems Corp d/b/a ID TECH, a manufacturer of magnetic stripe card readers, implicating the Magnetic Secure Transmission technology in Samsung Pay; Kennerly and Brann’s claim construction theories were adopted, denying ID TECH the ability to prove infringement and leading to final judgment in Samsung’s favour, which the Federal Circuit affirmed. Brann’s forensic cross-examination of the plaintiff’s technical expert was instrumental in this one. San Francisco-based Thomas Counts, meanwhile, has been representing Alignt Technology in numerous large-scale cases against competitor 3Shape in district courts and the ITC, joining forces with DC-based Allan Soobert in a perfect illustration of productive bi-coastal cooperation.

Perkins Coie LLP

“Perkins Coie knows the path to victory in critical patent litigation and excels at putting together, briefing, arguing and trying winning cases. Its lawyers are easy to partner with, make themselves available to in-house counsel and engineering teams at a moment’s notice, are team oriented and take both a legal and business approach to matters. From the moment of hiring, they impress with their technical expertise and creative and flexible – or rather, more strategic – style: they don’t stick to the cookie-cutter ‘prove technical non-infringement and/or invalidity’ method, but craft persuasive themes and stories that include much more than the usual patent defence.” A strong litigation bench in California is headlined by John Schnurer, Matthew Bernstein, Sarah Piepmeier and Tom Millikan. Schnurer and Bernstein serve as co-managing partners of the Taipei office and maintain vibrant ITC as well as district court practices. Schnurer – who recently handled one of HTC Corporation’s most significant patent cases, an 11-patent spat with Philips – is a “great negotiator and perfect communicator” who is extremely conscientious about the cost-benefit ratio of his actions. Bernstein – the relationship partner for the individual who provided the lengthy reference above – recently secured an initial determination of no violation of Section 337 in a three-patent infringement investigation relating to garage door and gate operator technology at the ITC on behalf of Nortec Security & Control. For Piepmeier, defending Cisco Systems against Netfuel was a big part of her 2020. Also focusing on high-technology affairs, Bing Ai, Amy Simpson, Brian Coleman and Dana Hayter fuel the firm’s West Coast prosecution and post-grant and transactions practices. Ai takes the lead on PTAB matters and is a vital buttress to litigators such as Schnurer, with whom he acts extensively on behalf of leading Asian communications and semiconductor companies. Simpson hails from a litigation background and thrives in inter partes reviews and other America Invents Act trials. Both entrepreneurially and technically minded, Coleman does a wonderful job prosecuting in the areas of social media, cloud computing, clean technology and many others. Transactional don Hayter undertakes licensing for a client supported by Ai and Schnurer, in a great example of the total support that Perkins Coie can offer. On the life sciences front, superb leadership is provided by Michael Wise, a renaissance man who manages portfolios, litigates in court and represents parties in post-grant proceedings. Chemistry and biochemistry PhD Viola Kung also acquits herself with distinction for pharmaceutical and biotechnology companies, specialising in patent procurement; she knows how R&D labs work, having spent over a decade in them herself, which ensures she can speak on a one-to-one level with inventors.

Quinn Emanuel Urquhart & Sullivan LLP

“The breadth and quality of Quinn Emanuel’s trial team promote healthy internal discussion and debate about strategy. You can count on the firm to have thought through each critical litigation decision from a variety of different angles, and to come up with the best and most tactical approach. Its agility also enables it to pivot quickly when the circumstances call for it.” The crack patent litigation outfit has some of its best trial lawyers stationed in California, including Victoria Maroulis and Kevin Johnson, who have been representing Samsung Electronics against Evolved Wireless in an infringement matter relating to five patents that Evolved alleges are essential to the LTE cellular standard; and fellow Silicon Valley attorney Claude Stern, who recently handled a critical case for autonomous vehicle start-up WeRide against two former employees and their new company, AllRide, obtaining two preliminary injunctions against the defendants. Holding it down in San Francisco, meanwhile, are national IP litigation practice co-chair Sean Pak and Charles Verhoeven, the head of the Northern California offices and an otherworldly trial lawyer with multiple billion-dollar wins on his record.

Ropes & Gray LLP

Complementing its district court litigation practice with highly specialised ITC and post-grant offerings, Ropes & Gray has proven itself a decisive winner wherever a patent dispute lands. Its life sciences practice has come on in leaps and bounds recently, thanks to the efforts of its East Coast lawyers; while out in California, special operatives such as James Batchelder and Andrew Thomases keep the firm hot on the radar of major technology companies. From a client perspective, though, east or west hardly factors into the equation, such is the seamlessness of the collaboration across offices. Batchelder, for example, has linked up with DC-based ITC ace Matt Rizzolo in representing Emerson Electric in a long-running battle with SIPCO concerning Emerson’s smart wireless products; recent wins include a January 2020 initial determination of no violation at the ITC and an August 2020 inter partes review result finding all claims of one of SIPCO’s asserted patents unpatentable. The Emerson Electric ITC and PTAB work, underlying which is a district court litigation, is an excellent example of the group’s multi-forum abilities, team approach and international proficiency: cooperating with German counsel, Batchelder and his colleagues also secured a judgment of non-infringement in their client’s favour before the Mannheim Regional Court. Thomases has also been partnering with Rizzolo to represent content streaming and device company Roku in various mission-critical suits, including most recently an ITC complaint filed by Universal Electronics. Ropes & Gray is also acclaimed for its dependability in technology and patent transactions scenarios. Making her debut in the IAM Patent 1000 this year, Megan Baca is the deals maven in California. Her recent biopharmaceutical engagements include advising a US client on a non-exclusive worldwide IP licensing agreement with a UK-based company; while on the high-technology side, she assisted Qorvo – a leader in radio frequency solutions – with numerous matters, including its acquisition of Decawave, a pioneer in ultra-wideband technology.

Schwegman Lundberg & Woessner PA 

Firms don’t get as clear a look into competitors’ prosecution offerings as they do in the head-to-head practice of litigation, making peer feedback in this space harder to come by; that said, there’s never any shortage of recognition for the quality on offer at Schwegman. The innovative, technologically advanced boutique of 120 experienced attorneys and agents procures cast-iron patents that confer a distinct business advantage on their holders. Andre Marais is a magnet for Silicon Valley companies, but has an international reputation that draws in clients from Germany, China and elsewhere. He has a complete command of networking, software, communications and electrical technologies.

Sheppard Mullin Richter & Hampton LLP

Newly added to the California prosecution table this year, Sheppard Mullin takes care of the portfolio needs of some of the biggest names in technology. Silicon Valley-based James Soong represents Facebook and Lyft and, for both, has obtained a significant number of patents protecting their most critical innovations. Soong is blessed with rich global IP strategic expertise and is a former in-house counsel whose business sense chimes with clients. As a trusted adviser, Lorna Tanner is equally essential to her pharmaceutical and biotechnology followers, including Gilead Sciences, whose breakthrough hepatitis C drugs she is responsible for protecting. Both Soong and Tanner play a strong hand in the firm’s post-grant practice, which is recognised as one of the best in the country representing petitioners and one of the most successful overall. Central to this is Silicon Valley managing partner Harper Batts, who comes in for loud applause: “Harper is detailed oriented, extremely efficient, effective at communication and a great oral advocate. He knows every PTAB decision, which helps him keep his strategies current. He also understands the propensities of PTAB judges on specific issues.” Steven Korniczky and Martin Bader are also elite post-grant performers and, like Batts, excellent all-round litigators, too. Lately, they have won a significant number of matters on behalf of HTC against INVT SPE – a patent assertion company funded by Fortress Investment Group – in the ITC and at the PTAB. They also handled a complex case on behalf of u-blox, a Swiss developer of cellular modules used in automobile navigation systems, which alleged that Sisvel had violated antitrust law and used its monopoly of SEPs for cellular technology to demand unreasonably high royalty rates; the two companies entered into a worldwide, non-exclusive patent licence agreement in September 2020. Licensing disputes are something of a forte for the pair, who have also been representing Continental Automotive Systems in accusing various patent holders of standard-essential 2G, 3G and 4G cellular patents of colluding to artificially inflate royalties.

Sidley Austin LLP

Sidley Austin’s West Coast IP litigation team regularly makes the headlines, for all the right reasons. The endeavours of Michael Bettinger have everything to do with this: the eminent trial lawyer leads the group and puts in resonant performances on behalf of industry behemoths such as Microsoft and Amazon. For the latter, he has gone up against high-flying Texas-based outfit McKool Smith as the representative of Speedtrack, which alleges that the faceted search feature on commercial websites infringes its patent; for the past 10 years, Amazon has aggressively led the defence effort in the case, which has been filed against a number of other companies offering e-commerce services. Vernon Winters is another litigator for whom trial success is a recurrent storyline. He’s done some big things in the life sciences and, in a biosimilar litigation against Sandoz, recently won a favourable Federal Circuit ruling of validity of two Amgen and Immunex patents that describe and claim its blockbuster rheumatoid arthritis drug Enbrel and methods for making it; Amgen’s stock price increased by more than 8% upon news of the result. Big-ticket instructions are very much the order of the day for Sidley’s technology and IP transactions specialists, too. Global co-chair Glenn Nash represents Facebook in numerous strategic alliance deals with key technology partners such as Google, Samsung and Apple; and in deals with handset manufacturers and telecommunications companies. Joshua Hofheimer works across many industries, but has been on a sparkling run of form in the life sciences of late, including representing GlaxoSmithKline in a collaboration with and equity investment in Lyell Immunopharma to develop new technologies to improve cell therapies for cancer patients.

Sullivan & Cromwell LLP

Sullivan & Cromwell stands tall as one of the world’s best for technology deals. It comes close to perfection in its stewardship of complex standalone technology and patent transactions, as well as larger corporate deals, thanks in large measure to the leadership shown by “top IP strategist and innovative attorney” Nader Mousavi. Connecting with New York partner Mehdi Ansari, he recently represented DISH Network in its acquisition of the Boost pre-paid mobile business of Sprint for $1.4 billion in cash. Mousavi started his career as the general counsel of a telecommunications software company and works extensively in the TMT field, but he’s unbounded in terms of industry sector, technical subject matter and transaction type – he’s simply an amazing all-rounder.

Susman Godfrey LLP

Undaunted by the most challenging cases, Susman Godfrey has a hearty appetite for bet-the-company patent litigation. Its practitioners relish the opportunity to present in court and seize it with style while delivering on substance. Included in the IAM Patent 1000 California firm rankings for the first time this year, it also has a new face in the guide in Meng Xi, a recently promoted partner who has flourished with her newfound responsibilities. “Meng prepares very well-reasoned, highly effective briefs in both trial and appellate settings, and her oral advocacy is superb. She is also an excellent contract drafter and negotiator, which is a skill not commonly found in trial advocates. Her extensive technical background is a further benefit.” She has been an integral part of trial teams litigating on behalf of Personalized Media Communications – the owner of one of the world’s most valuable patent portfolios – in a series of cases pending in the Eastern District of Texas against streaming media providers Google, Netflix and Akamai; and for Vaporstream against SnapChat subsidiary Snap. Xi is following in the footsteps of managing partner Kalpana Srinivasan, who makes her sophomore appearance in the rankings. An exceptional leader, Srinivasan is taking the patent litigation world by storm.

Weil Gotshal & Manges LLP

As a national platform for high-dollar patent litigation, Weil turns the heads of the loftiest technology companies. Without making a song and dance of it, the ensemble diligently builds compelling trial themes and advances its clients’ business objectives. This is the modus operandi of Edward Reines, who co-heads the US patent litigation practice. Solid gold in the IAM Patent 1000, Reines is a calm and collected litigator with a marvellous trial performance history. On the biotechnology front in 2020, he secured a major Federal Circuit victory for long-time client Bio-Rad Laboratories and the University of Chicago, upholding a $24 million patent jury verdict – obtained in 2018 against 10X Genomics – and a permanent injunction against virtually all of its adversary’s infringing products. Fellow Silicon Valley lawyer Anne Cappella also litigates at the highest level, but plays a broader role in dedicating a substantial part of her practice to strategic IP counselling – she takes charge of Weil’s efforts in this regard. Leading on the transactions front, meanwhile, is Karen Ballack, an “outstanding drafter and negotiator whose deep knowledge of and experience with intellectual property proves invaluable in many types of deals”. Sources also highlight the superb training that Ballack gives to her associates, who “display the same professionalism and high standards as Karen does”. In advising Apergy on the technology and IP aspects of its Reverse Morris Trust acquisition of ChampionX Holding, she oversaw, among other things, the acquisition of 1,700 patent assets worldwide and a complex patent cross-licence arrangement.

White & Case LLP 

White & Case unveiled Jonathan Lamberson as its new signing in Silicon Valley in September 2020. The former Fish & Richardson lawyer brings cutting-edge SEP and FRAND expertise to the team, along with extensive trial experience. Courtroom know-how was already in plentiful supply at the firm which, in Bijal Vakil, has another assured litigator on the West Coast, as well as an adept all-round strategist. Vakil is a vital cog at the firm, having led its Silicon Valley office for a lengthy period, founded its Taiwan practice and played an important role on the diversity and inclusion front. With a flair for the fine print of licensing agreements, Vakil also leans into a gilt-edged transactions practice, crucial to the success of which are Daren Orzechowski and Alexander Touma. Versatility characterises Orzechowski’s service, in terms of the clients he serves, the deals he brokers and the technologies he handles – nothing fazes him. A previous stint as an in-house counsel has given Touma an appreciation of the practical and business realities faced by his clients.

Wilmer Cutler Pickering Hale and Dorr LLP

WilmerHale puts in frequent winning appearances in all the main patent venues and within its walls are some of the very best district court litigators, ITC specialists, post-grant proceedings professionals and appellate advocates the United States has to offer. Take Los Angeles partner James Dowd, for example: he’s a “seasoned and skilled trial lawyer” who is “willing to roll up his sleeves and do what’s necessary to master the technology and prior art so as to be able to put forth the best arguments”. “He is direct and succinct, and has a strong courtroom presence, as well as being very easy to work with.” Palo Alto-based Mark Selwyn, Sonal Mehta and Robert Galvin are all fashioned from the same material as Dowd. Selwyn serves as co-chair of the IP litigation group and has been a rock for the firm and its prestigious patrons since he joined in 1994. A much more recent arrival, Mehta has entered prime time and is fast establishing herself among the crème de la crème of Californian patent lawyers. Galvin is a must for life sciences and software suits.

Wilson Sonsini Goodrich & Rosati

Built to service the total corporate, IP, litigation and regulatory needs of ground-breaking innovators, Wilson Sonsini has made an indelible impression on the US patent landscape. The firm is especially well known for its rare transactional IP faculties and specialised, high-calibre practitioners, such as Kenneth Clark and John Wehrli, who shepherd transformative deals across the line. Both lawyers are fluent in the life sciences and responsible for strategic alliances that have the industry buzzing. Primarily supervising prosecution for pharmaceutical and biotechnology companies, Matthew Bresnahan also gets involved in transactions and was recently part of a team that advised Prometheus Biosciences on IP issues relating to its initial public offering. James Heslin is the centre of gravity for a vibrant medical technology practice; he fulfils a similar role to Bresnahan as a 360-degree counsellor. Edward Poplawski and James Yoon ensure Wilson Sonsini’s high-level engagement in complex patent litigation.

Winston & Strawn LLP 

Winston & Strawn’s attorneys are famous for their imposing courtroom presence; an equally important ingredient in their success is the way in which they immerse themselves in the technologies at issue to understand them at the deepest possible level. “Terrific” patent litigator Michael Rueckheim is a case in point: “He has a keen technical ability along with practical judgement and a great ability to manage and run large teams – a combination of talents that is hard to find.” He is a central member of a California squad that includes Kathi Vidal, with whom he has been litigating extensively: they closed out an ITC case with a favourable settlement on behalf of Olympus Corporation regarding advanced, minimally invasive therapeutic and diagnostic technologies; and are representing VMware against Intellectual Ventures in two litigations and related PTAB proceedings involving 10 networking and virtualisation technique patents. Vidal is one of Winston’s top guns and serves as Silicon Valley managing partner. The group is full of big names, with additional firepower supplied in abundance by David Enzminger, Michael Tomasulo and Nimalka Wickramasekera. Coming in for praise, Enzminger is “deeply thoughtful about the most efficient and effective approaches to patent litigation and strategic case management. He responds quickly and solves complicated problems in practical fashion”. After five years of litigation – including a dozen inter partes reviews and a trip to the Federal Circuit – he and Tomasulo won a decisive victory for Take-Two Interactive Software in dismissing all claims made by a patent assertion entity alleging that Take-Two’s multi-player technology for its Grand Theft Auto and NBA 2K videogame franchises infringed its patents. Wickramasekera’s highlights include defeating a preliminary injunction sought by Nuvasive, a competitor to her client Alphatec, thereby keeping the latter’s new spinal surgery device on the market.

Womble Bond Dickinson (US) LLP

Intellectual property is a central pillar of Womble Bond Dickinson’s wider legal offering in California – in fact, it accounts for as much as 85% of its output. On the West Coast, it has assembled a cadre of precision prosecutors who undertake complex work for high-profile companies. For example, IAM Patent 1000 debutant Kevin Shao serves as outside patent counsel for Dell EMC, handling US and foreign patent procurement activities and managing more than 800 matters worldwide. Shao is a former electrical engineer, software developer and software consultant whose technology and industry experience stand him in excellent stead. James Scheller also shines on software matters within his broader electronics, computer science, internet and medical device practice. He’s a veteran with a fine-milled understanding of patent value. So too, all-seeing strategic counsellor Dan Ovanezian, who is part of a team serving as global preparation and prosecution counsel to enterprise data storage company Pure Storage. PTAB trial work is the other major focus locally, with Brenton Babcock in the driving seat. Exercising his powers of persuasion at the PTAB, he recently lodged an ex parte appeal and reversed an examiner’s final rejection of client Komori Corporation’s patent. His current caseload includes a matter for the Korean Advanced Institute for Science & Technology (KAIST), which retained him to lead an effort to reverse the USPTO’s rejection of its patent claims which occurred following an ex parte re-examination request by Samsung filed in the wake of KAIST’s $400 million jury verdict against it.

Other recommended experts

Craig Allison and Jonathan Baker form a superb litigation team at Dickinson Wright. They design and execute smart strategies, litigate vigorously, have an excellent record winning critical and heavily contested motions and acquit themselves with distinction all-round. Lately they have been putting in a strong performance defending Roku in multiple lawsuits, including one in the ITC, filed by Universal Electronics. Increasing in stature as a patent litigation boutique, Armond Wilson is primed and ready for complex court litigation, PTAB battles and Federal Circuit appeals. Michelle Armond – who recently represented Zoom Video Communications in a case relating to video conferencing technology – is brilliant on both the tech and the presentation. She and fellow founding partner Douglas Wilson, an Austin-based practitioner and fellow IAM Patent 1000 inductee, form a dynamic strike force. Duane Morris trial lawyer Stuart Bartow has had some notable successes for Trend Micro, including against Intellectual Ventures, and is currently representing it in the Western District of Texas against claimant Eighth Street Solutions. His strategies are aggressive, but thoughtful. In the firm’s Palo Alto office, colleague Philip Woo is an all-rounder with a wealth of litigation, prosecution and post-grant expertise. On the portfolio development side, Woo undertakes significant work for LG Electronics, including in the connected vehicle area, where he leans heavily on his standards-related knowledge. Asim Bhansali’s name is on the winning side of some oft-cited patent decisions; his number is dialled when there’s a lot on the line, thanks to the level and extent of his courtroom experience and know-how. He came up in the game at Keker & Van Nest, but now runs things at Kwun Bhansali Lazarus. John Brockland of Hogan Lovells is a technology transactions leader who has closed myriad big deals for leading technology companies. One of his 2020 highlights involved supporting Intel in connection with the IP aspects of its $900 million acquisition of Moovit – a deal overseen by colleagues in the corporate department. Aaron Capron builds portfolios from the ground up that create commercial opportunities for clients while limiting the manoeuvrability of their competitors. He can take seemingly unpatentable inventions and prosecute them to successful grant where others can’t – something he has done for innovative digital health solutions company Grand Rounds. He and Erik Puknys are Finnegan’s rainmakers in Silicon Valley and partner closely with patrons to protect them worldwide; they jointly support ASML Netherlands on all aspects of prosecution and patent strategy. Ko-Fang Chang joined Weave Austin Villeneuve Sampson in July 2020, following a switch from Kilpatrick Townsend. A savvy business counsellor and seasoned post-grant lawyer, he brings a lot to his new digs. Siegmund Gutman chairs the life sciences patent group at Proskauer – and it’s a good one (think of Fangli Chen in Boston and Daryn Grossman in New York). The star litigator in the practice, Gutman is an accomplished trial lawyer with reassuringly well-rounded strategic counselling and Food and Drug Administration regulatory expertise. He has carved out a sterling reputation in the biosimilars space and is representing Amgen in a high-profile matter under the Biologics Price Competition and Innovation Act concerning its development and commercialisation of a biosimilar to Genentech’s Avastin monoclonal antibody cancer therapy, one of the world’s blockbuster drugs. Shawn Hansen “has a strong command of US patent law and is an excellent litigator and well-spoken, succinct presenter who makes complex issues easy to understand. He does a superb job managing large cases and provides smart strategic advice”. He is based in Nixon Peabody’s Los Angeles office, down the hall from life sciences co-chair Seth Levy, who also comes in for enthusiastic praise: “Seth is very down to earth and a great communicator. He has specialist expertise advising universities and research institutions on strategic prosecution and portfolio management – and his licensing abilities are unmatched.” Flying the flag of BakerHostetler in Orange County, Mark Krietzman showcases an incredibly diverse IP skillset in handling prosecution, strategic advisory, transactional and contentious briefs involving patents and trademarks. He’s a straight shooter who understands how to minimise business risk. Squire Patton Boggs has a veteran litigator in Ronald Lemieux, who has represented A-list companies in IP disputes well into the triple digits. He has gone the distance at trial on many occasions and can back up his wins at the Federal Circuit. A pivotal member of Shearman & Sterling’s IP transactions group, Emma Maconick utilises a well-rounded patent and technology commercialisation and data privacy skillset to assist marquee clients such as Facebook Technologies, which she advises on product privacy, data security, intellectual property and other matters. Anchoring the west coast litigation practice, meanwhile is L Kieran Kieckhefer, a savvy and experienced litigator who excels at getting to grips with complex and diverse technologies, cross-examining witnesses, and leading trial teams. Aside from running a dynamic practice, she makes an important contribution to the advancement of women in the legal profession. Fabio Marino is “an experienced litigator who thoroughly understands technology and is extremely well versed in patent law and USPTO procedures. He is highly devoted to his cases and his clients”. The Polsinelli partner has an affinity for complex computer-related technologies and serves as lead counsel representing Radware in litigation against F5 Networks. The successor to the Ropes & Gray rights management practice, boutique Haley Guiliano has a focus on prosecution, portfolio development and IP commercialisation. However, it is fielding an increasing volume and array of contentious instructions, many of which land on the desk of career litigator and trial lawyer Richard McCaulley. He has a pristine track record in the pharmaceutical and medical device spheres, given his combination of relevant technical expertise and advocacy skill. His colleague in San Jose Joshua Van Hoven focuses on the prosecution and counselling side, but also handles contested proceedings at the USPTO with finesse. FisherBroyles attorney Alan Minsk represents a diverse catalogue of clients from small to large and in many technological disciplines. He dials in the right strategies for each, neatly tailoring them to the wider commercial imperative; while his technical fluency means he is frequently called to support invention mining efforts. James Nelson takes the reins of Venable’s San Francisco office. An astute corporate attorney with a specialisation in technology and IP transactions, he understands the business of patents. John Neukom anchors Skadden’s patent litigation practice out west. He’s a veteran of the smartphone wars, has handled major trade secret litigation in the autonomous vehicle area and has represented a host of major technology names in dozens of suits. Previously based in Texas, Michael Newton of Alston & Bird recently took up residence in the firm’s Silicon Valley office. He’s an integral member of a potent litigation group and one of its most experienced trial lawyers in the Eastern District of Texas, where he recently secured a rare summary judgment ruling from Judge Gilstrap on behalf of Nokia – a client which he also supported in a major ITC investigation, to great effect. Alston & Bird maintains a robust patent prosecution and portfolio management practice too, which is anchored on the West Coast by smart strategist Ardeshir Tabibi, a favourite of the California Institute of Technology. Buchalter special counsel Cecily Anne O’Regan is a business-minded patent attorney who is warmly praised for her “deep strategic insight and invaluable coaching skills”: “She can put in place foundational patents on which rest the success of new business ventures – what she does is of unquestionable value.” She represents emerging companies in the medical device, biometric, software and clean technology arenas. Another highly rated Buchalter pro is IP cochair and dynamic patent and trademark litigator J Rick Taché: One client comments: “Rick is the smartest IP guy I have ever known. He can look at an aspect of a product’s function he doesn’t know about and immediately ask the most penetrating questions about the invention and its possible improvement – he’s an incredibly quick study. His service ethic is tremendous, which is of paramount importance – when we need him, he is always there for us.” Echoing similar sentiments, another adds: “Rick’s patent knowledge is second to none and his commercial expertise is selfevident, too. He can do in two weeks what would take other larger firms four weeks to complete – his speed is critical to us. He communicates regularly and is very clear on strategy, which is of immense comfort.” Matthew Powers is a fabled patent litigator and the founding partner of Tensegrity Law Group. A magician at trial, he pulls through in the heat of the moment. In January 2020, Jeannine Yoo Sano made the switch from White & Case to Axinn, joining a stacked bench of nationally reputed patent litigators who, like her, demonstrate refined trial skills. An experienced lead counsel with a number of firsts on her CV, she’s unafraid of tackling difficult cases involving challenging subject matter in any forum. Rimon partner Dale Rieger is a trusted adviser to life sciences companies; his portfolio management, litigation counselling and transactional skills are all top drawer. A household name in Silicon Valley, portfolio developer Robert Sachs has specialised knowledge of Section 101 issues and SEPs, putting him in hot demand as a strategic counsellor. Brown Rudnick onboarded David Stein as a partner in Orange County in August 2020. The former Greenberg Gross litigator knows how to handle himself in the courtroom, having tried 15 cases to verdict. He has an agile technical mind and thrives in complex cases in which the skill of breaking down technology for laypersons is especially important. For companies looking to build out their portfolios in the areas of AI, automotive technologies, software and telecommunications, among others, Nick Transier of Patterson + Sheridan is a discerning choice. The former systems engineer – and auto enthusiast – lives and breathes the technology, but has a good strategic head on his shoulders. Lee Van Pelt has been in the thick of patent practice in Silicon Valley for two-plus decades, during which he has prosecuted extensively and represented the interests of technology investors. He is a founding partner of Van Pelt, Yi & James. Joseph Yang of PatentEsque Law Group practises at the frontier of developments in IP law, technological innovation and the business of licensing. He is highly recommended for his expertise in convergence deals in which businesses that might not traditionally connect come together.
