Adsero IP

“Adsero IP has a talented team with a number of commercially attuned practitioners who have interesting niches.” Kenneth Chang, for example, matches expertise in IP strategy, licensing and enforcement with rich cultural and business knowledge in the Asia-Pacific region, giving the firm a real USP. Katherine Lobel-Rice, meanwhile, is one of only a handful of Coloradans in the IAM Patent 1000 with a life sciences PhD – she earned her doctorate in pharmacology – creating an advantage for the ensemble in attracting complex pharmaceutical and biotechnology mandates. High-technology experts Chad King and Daniel Young, meanwhile, take advantage of their blended prosecution and litigation skillsets to support rights holders throughout all phases of the patent lifecycle in a way that few others can. These attorneys form a sophisticated collective with a laser customer-service and quality focus.

Brownstein Hyatt Farber Schreck LLP

Well versed in all facets of patent practice and in the mechanical, electrical and software arts, Brownstein Hyatt Farber Schreck provides a reassuringly comprehensive offering to technology companies. Deriving strength from its proficiency not just in procuring patent rights, but also in monetising them, the firm makes it its mission to add bottom-line value. Craig Hemenway does this particularly well, which is one of the reasons why household-name companies such as T-Mobile seek him out for wide-ranging patent and licensing matters. Benno Guggenheimer demonstrates his understanding of the business of intellectual property in “delivering actionable advice which is sensitive to clients’ commercial needs”: “Benno has immense technical expertise and is highly efficient. He crafts detailed and accurate patent applications, producing work that inventors love to see. He is insightful, thorough and incredibly practical, and very personable, too.” He is well thought of among Silicon Valley companies, but has an international reputation and serves as primary US patent counsel for Australian software company Atlassian.

Dorsey & Whitney LLP

Dorsey & Whitney is admired for its “well-rounded practice” that spans patent and trademark protection and IP litigation: “Its attorneys have mastered their art and are loved by their clients.” This is certainly true of Kerith Kanaber, who co-chairs the healthcare industry group and trades as a prosecutor and portfolio manager for consumer products, medical device and life sciences entities. “Kerith has exacting attention to detail, is flexible in terms of budgeting, has a thorough understanding of the portfolios in her care, appreciates her clients’ unique business needs to better shape strategy and is highly responsive.” Naturally talented and self-motivated, she has also benefited greatly from the mentorship of Lee Osman, the long-serving leader of Dorsey’s patent group. In competitive industries, Osman keeps clients out in front of their rivals by obtaining valuable intellectual property and deploying it in commercially clever ways. Gifted at getting multiple parties pulling in the same direction, he links up with the right collaborators across the firm and leverages his connections with top service providers worldwide to support patrons wherever they need him. Alongside Kanaber, one of Osman’s most valued colleagues is Gregory Tamkin, who is the star litigator on deck in Denver.

Faegre Drinker Biddle & Reath LLP

Between them, Kirstin Stoll-DeBell, Kathleen Ott and Timothy Scull cover all bases for all types of innovators, creating a potent platform in Colorado for Faegre Drinker. Stoll-DeBell puts the focus on high technology and acquits herself with distinction as a portfolio strategist and opinion giver; she also litigates and brings valuable trademark know-how to the table. Her practice dovetails neatly with that of Ott, who prosecutes with precision in the computer science and software space, but also extends into the medical device and pharmaceutical area; he adds another dimension to the firm’s offering as a tried-and-tested post-grant lawyer. Tim Scull is a guiding light for electronics and especially software clients, including industry leaders.

Holland & Hart LLP

“Holland & Hart’s group of patent prosecutors is one of the very best in the world. It functions as an extension of in-house teams by making it a point to understand clients’ technologies and develop strong relationships with inventors. You can always trust its lawyers to write quality applications, prosecute them timeously and work tirelessly to achieve the best possible results. As any in-house practitioner will attest, having diligent, reliable prosecution counsel such as Holland & Hart enables companies to increase their individual leverage and focus on other pressing matters for their business.” “The firm has top talent on board, including attorneys and engineers, and a well-structured workflow that results in high-quality outcomes.” “The group’s success and deep expertise is a direct result of Michael Drapkin’s masterful leadership and recruiting. Michael – himself one of the world’s foremost experts in patent matters – has the ability to identify, develop and deploy talent in a way that rivals the sporting world’s greatest general managers. His team includes personable relationship managers, seasoned patent professionals, highly credentialed technologists, skilled negotiators and multilingual drafters – all of whom approach matters with a singular focus on excellence.” Also garnering high praise is Paul Schramm, who “never fails to impress with his creativity and resourcefulness”: “Paul always goes the extra mile to help you invest strategically in your intellectual property without breaking the bank. His clear thinking enables smart decision making – he carefully enumerates options, showing a good grasp of the technical and business picture.” Per Larsen is another key cog of the practice, particularly given his technical fluency: he enjoyed a career as a design engineer prior to entering the practice of law. Patent litigation is another forte of the firm, which in Timothy Getzoff has one of the state’s elite contentious lawyers. Getzoff is a veteran who has litigated all over the country – primarily in the patent area, but also in trademark and copyright disputes.

Kilpatrick Townsend & Stockton LLP

Recommended on each of the prosecution, litigation and transactions tables, Kilpatrick Townsend presents a well-rounded offering in Colorado – and one which is seamlessly integrated with a national group that is among the biggest and best. The firm got off to a great start in Denver in the mid-1990s as the local office was established by one of the city’s top patent prosecution, counselling and transactions lawyers, Darin Gibby. He obtains patents that serve as cornerstones for the business growth of worldwide companies and that help those launching new product lines to do so without a hitch. He comes from a mechanical engineering background, but works on a lot of cool stuff in diverse sectors from software, finance and telecommunications to medical devices, sporting goods and food processes. He is one of several percipient strategists locally, including chemistry PhD and superb draftsman Eugene Bernard, with whom he regularly collaborates; Thomas Franklin, who has a proven ability to grow portfolios around technologies that are hard to patent – and to do so quickly in industries in which competition is ramping up; and Denver managing partner Justin Krieger, a polished performer in post-grant proceedings who has been instrumental in the firm’s representation of Ascend Performance Materials against Samsung, which recently resulted in the successful invalidation of a Chinese patent.

Merchant & Gould

Merchant & Gould has been an IP touchpoint for innovative companies and academic institutions for over a century. With more than 100 lawyers, patent agents and technical experts on deck, the well-resourced boutique continues its legacy of partnering excellence, which individuals such as Andrew Jagenow and George Lewis do much to sustain; both are skilled portfolio managers with heightened awareness of business and risk. Mechanical engineer Jagenow focuses on manufacturing and medical devices; trained in the electrical and chemical arts, Lewis works across a vast range of industries. The fulcrum around which the Denver practice turns is Gregory Leibold, who serves as local managing partner, co-chair of licensing and leader of the electrical and software group. The former general counsel counts versatility as a key strength.

Perkins Coie LLP

The sheer volume of instructions it handles and an astonishing hit rate across all major forums – often in precedent-setting cases – set Perkins Coie apart as a formidable force in patent litigation. Among its many stellar advocates, Amanda Tessar stands out as a “highly intelligent and energetic lawyer with a will to win. She has superb experience representing clients in complex matters in the semiconductor industry”. “She doesn’t waste money on arguments that won’t advance her case, and she provides practical solutions and timely updates – and sticks to her budget.” Compared to many other general practice patent litigation high-flyers, Perkins Coie also has an especially robust prosecution and licensing offering. As on the contentious side, its services here are sophisticated: the firm may get several thousand US and foreign patents issued each year, but it’s no mere filing mill – its patenting efforts are underpinned by deep strategic thinking around the business of intellectual property. Engaging freely in this, David St John-Larkin, Brian Kinnear, Michael Henson and Peter Kinsella form a high-calibre line-up in the Denver office. St John-Larkin takes the lead in representing a key client in the 5G space and undertakes prosecution tasks while regularly conducting due diligence and patent analysis in support of proposed transactions, with a focus on the licensing of SEPs. Exposure to litigation has given Kinnear refined risk sensitivity, which translates into effective long-term strategising. Central to the firm’s blockchain practice, Henson is endorsed as a “creative lawyer skilled in his craft and who sees the big picture”. Licensing maven Kinsella is responsible for negotiating the sorts of collaborations that define the trajectories of emerging industries.

Polsinelli PC

Polsinelli’s Denver office is one-stop shop for innovators: the team prosecutes patent applications with finesse, has a flair for the fine print of IP-rich transactions and litigates with tenacity. The local group has a new face in the IAM Patent 1000 this year in Taryn Elliott, one of several next-gen stars making Polsinelli a prime destination now and into the future. “Taryn understands the competitive IP market and her strategies for navigating it are essential to business growth. Perfectly fitting the description of trusted business adviser, she thinks beyond intellectual property and adds value to any discussion.” She leads the product design and user interface group. On speed dial for several Fortune 500 medical technology companies as well as prestigious universities, Wade Johnson is also enthusiastically recommended: “Wade is adept at grasping the unique details of complex systems and goes the extra mile to visit facilities and discuss new products with inventors. He provides tremendous support in identifying what is patentable, surveying the landscape, reviewing competitive product and harvesting claims, among other things; and does excellent work at an affordable cost.” Gregory Durbin demonstrates impressive technical range and, in a similar fashion, loves to get hands-on with new communications, computer hardware, software, energy and other technologies. His guidance smooths the path for those introducing new flagship products to the market in fiercely competitive spaces. Anchoring the litigation practice are John Posthumus and Michael Dulin, who both stand out for their trial experience. Gold-ranked Posthumus has an “incredible intellect” and is a “true professional of the utmost integrity”.

Sheridan Ross

“A lot of firms fail to successfully monetise patents, but this is something that Sheridan Ross excels at – and it is ultimately what matters to clients and funders. It’s a high-performance litigation outfit too: its lawyers have good judgement and risk assessment ability. The firm is easy to work with, reasonable on terms and has great technical depth.” On the latter point, the eminent local boutique has the largest number of individuals (seven) recognised for prosecution in the Colorado rankings. Co-president Matthew Ellsworth is a must for the protection of complex electrical and software technologies; as is Douglas Swartz, with whom he connects on behalf of gaming technology and computer companies. The pair integrate well with product development and in-house teams in a way that streamlines work and pays rich dividends. Bruce Kugler and David Kellis also build lasting connections. Kugler is close to many international companies with diverse portfolios, which rely on his broad patent and trademark, counselling, licensing and litigation skillset to get the most from their intangible assets. A recently elected shareholder, Kellis has an intuitive business understanding that strengthens his relationships; he too treats clients to a well-rounded service by drawing on his patent strategy, transactional and litigation expertise. Meanwhile, Gary Connell and David Walker have earned Sheridan Ross a loyal following in the life sciences. Like Ellsworth and Swartz, they form another highly capable pairing and have recently been supporting a pharmaceutical start-up on all IP matters, including the development of an extensive inter-continental licensing and supply agreement. On the litigation front, Rob Brunelli sets the pace for the group, which is also home to Todd Blakely. Gifted at brokering lucrative settlements, Brunelli also has plenty of trial experience to call on if negotiating isn’t a suitable option. The wide-ranging contentious and non-contentious nous of fellow veteran Blakely helps him to see paths through difficult disputes that others miss.

Wilmer Cutler Pickering Hale and Dorr LLP

For high-stakes patent mandates, particularly those that are litigious in nature, WilmerHale is always a smart choice. The prestigious outfit has a global reputation for its prowess in the courtroom, equally integral to which are the finely honed advocacy skills and thorough scientific education of its lawyers. Home to Mary (Mindy) Sooter and Benjamin Fernandez, the Denver office lacks neither trial proficiency nor technical talent. A seasoned first-chair litigator trained in electrical engineering and telecommunications, Sooter can effortlessly distil technology for laypersons and makes light work of complex, multi-patent, multi-forum disputes. Fernandez is an efficient utility infielder who manages portfolios, analyses competitive landscapes, issues opinions and licenses patents with a sure hand. Crocs is one client that makes use of the full range of his abilities, which extend across the areas of design patents, utility patents and trademarks.

Other recommended experts

Scott Alter and Jon Trembath give Michael Best a solid presence in Denver – Alter as a global patent procurement lawyer, portfolio manager and strategic counsellor; Trembath as an experienced litigator. “Heath Briggs has a rare level of knowledge in metallurgy and alloys, along with exceptional commercial acumen and global expertise. He is incredibly responsive and never hesitates to communicate any concerns or opportunities regarding worldwide prosecution and freedom to operate issues, which is greatly appreciated.” Greenberg Traurig is his base of operations. Creating IP value is the metier of Cara Crowley-Weber, whose understanding of the innovation and business mindset has won her a dedicated following of pharmaceutical, biotechnology, medical device and healthcare clients. She has a microbiology and immunology PhD; as does fellow FisherBroyles partner Rita Wu, who comes recommended for her “amazing skill at handling large, complex portfolios”. Another key contact at the firm is Ian Walsworth, an “incredible litigator with a deft touch in sensitive cases”. For licensing and patent and technology transactional support, Bryan Cave Leighton Paisner’s Jason Haislmaier is a discerning choice. His negotiation skills are on point and his deal know-how incredibly diverse. Lee Johnston is an adept trial lawyer called on for representation in fraught commercial and IP cases. He wears the colours of Haynes and Boone. Craig Neugeboren has design engineering, in-house and private practice experience, enabling him to see IP problems in the round and present well-thought-out solutions. He founded Neugeboren O’Dowd, a boutique which is relied upon for a wide range of strategic IP support. Technology companies love having Rex O’Neal in their corner: he really understands them and their issues, having founded companies and served as general counsel at others. He delivers unerringly accurate advice, whatever commercial or IP issues come up, and excels as a transactional partner. Paul Prendergast is an IP-focused finance and acquisitions specialist at Davis Graham & Stubbs. He draws on his experimental pathology PhD to provide technically, legally and commercially perceptive counsel to life sciences companies. Evan Rothstein co-captains the TMT industry group at Arnold & Porter. As a litigator, he has won important jury verdicts locally and in other districts, and fulfils the roles of lead counsel and team player very effectively. He is playing a strong hand in a group comprised of New York, Colorado, and DC lawyers representing Charter Communications in a major trade secret battle against Sprint. Charles Schwab of Catalyst Law Group is recommended in the IAM Patent 1000 as an astute global deal maker. His transactional know-how encompasses the broadest range of IP and technology-driven deals. Timothy Worrall recently made the move from Polsinelli to BakerHostetler, taking up dual residence in its Denver and San Francisco offices. He has an agile technical and strategic mind, and provides value-creating guidance to life sciences and medical device companies.
