Paul Hastings is a force to be reckoned with in US patent litigation and has high-powered teams stationed in California, DC, Illinois and New York. It is a firm you can put up against any opposition in complete confidence, given the level of senior trial talent on its roster and the strength of its record delivering satisfying results in courts across the country as well as the ITC. A talisman of the practice Yar Chaikovsky is a swashbuckling lawyer capable of withstanding and fighting back against any onslaught and ultimately winning. His tenacity was crucial to success for Snap Inc in litigation against BlackBerry (represented by Quinn Emanuel) on multiple patents related to mobile messaging technology. In securing summary judgment invalidating four of the six patents asserted and a stipulation to a dismissal with prejudice of the remaining two patents, Chaikovsky drew on his Federal Circuit, PTAB and Section 101 expertise. More broadly, Paul Hastings has developed a reputation as a leading light for Section 101 invalidity challenges. Chaikovsky has an excellent team around him and counts on the likes of Philip Ou, with whom he represented Snap and with whom he has been defending Applied Materials and its customers Samsung and Intel in multiple litigations against Demaray (represented by Irell); this involves other top lawyers at the group, including DC-based Naveen Modi and Allan Soobert, making it a good example of a cross-office effort that Paul Hastings gears up for with the minimum of fuss. Another collaborative instance involves representing Align Technologies in a Delaware case against its primary competitor, 3Shape, relating to digital dentistry software functionality, for which Soobert and San Francisco-based Tom Counts have come together. Other lawyers not to be trifled with are Elizabeth Brann and Chris Kennerly, who form an effective pairing. They have been representing Samsung in a case against International Technologies and Systems, which threatens Samsung’s mobile wallet service. Paul Hastings has enhanced its Northern California presence recently, unveiling former Keker, Van Nest & Peters partner Matthias Kamber as its new signing. He is cut from the same cloth as the others here, being an adept and experienced trial lawyer.

Paul Hastings is unanimously regarded as one of the nation’s leading post-grant firms; it is prolific at the PTAB and has clocked up crucial victories for many leading companies. The fulcrum around which this practice turns is global IP vice co-chair Naveen Modi, a preeminent expert who has been involved in well over 500 post-grant proceedings. His recent highlights are too numerous to describe in detail but include a clean sweep victory for Google in a series of inter partes reviews dealing with nine multimedia technology patents asserted by Virentem, every challenged claim of every patent being invalidated. With him on this, co-leader of the patent office practice Joseph Palys is also in his prime. Accomplishing equally great feats in federal district courts, the ITC and the Federal Circuit are Allan Soobert, Jeffrey Pade and Phillip Citroën, who form a strong litigation line-up in DC. Soobert and Pade linked up with Modi and Palys to mount an important defence for Samsung in a complex patent and trade secret case in which the defeat of opponent NuCurrent’s preliminary injunction was required to enable Samsung to pursue inter partes reviews. The result was the invalidation of all of the patents in suit, completely derailing the plaintiff’s litigation – a stark example of the efficacy of the ensemble’s teamwork and the potency of its blended skill set. Soobert and Citroën are defending Samsung in another high-stakes case implicating Samsung’s three-dimensional memory chips found in a wide-range of consumer goods. Paul Hastings is in a stronger position for ITC litigation than ever before, thanks to its recent addition of Kecia Reynolds, who joined from Pillsbury in December 2021. She has 20 years of ITC experience and is a former senior investigative attorney in the Office of Unfair Import Investigations.

Paul Hastings has astutely configured its patent group and has all the assets in place for present and future dominance of life sciences – and technology – litigation practice. Much credit in this regard goes to Bruce Wexler, a towering figure on the US market with a global reputation as a top trial lawyer. Blue-chip clients have flocked to the firm because of his presence, leading to a constant flow of high-profile instructions that has in turn created the opportunity for younger lawyers to get hands on and gain valuable practical experience. With some of those younger professionals now rainmakers in their own right – New York litigation chair Preston Ratliff comes to mind – a virtuous circle has been created to sustain the practice at the highest level. Looking at recent highlights for the group, the total victory secured for L’Oréal in a case filed by Carmel Laboratories and the University of Massachusetts was a notable one; 130 of L’Oréal’s products were accused, with the damages sought being in the range of $275 million; in this the judge granted a motion that all contested claims were invalid as indefinite, and followed it up with a new standing order setting limitations on summary judgment motions in patent cases, creating an analogy between winning such motions and hitting a hole-in-one in golf. Global IP Vice Chair Eric Dittmann led the team and was instrumental to this win, with a lead role also played by Isaac Ashkenazi, and assists from Wexler and DC-based PTAB and all-round litigation supremo Naveen Modi – all of whom are the sort of lawyers who get hired by companies they have previously hammered in court, which is a good measure of their effectiveness. Other top names on the roster include Chad Peterman and Melanie Rupert: Peterman is an IP and antitrust trial lawyer who undertakes extensive work for AbbVie and Genentech, which he is representing jointly in a Hatch-Waxman litigation protecting Venclexta from generic challengers; adept in the life sciences, Peterman works across many technical divides without breaking a sweat. Rupert has an important role to play not only as a dynamic litigator but also as global co-chair of talent development within the outfit; coming back to the point about future dominance, she is doing an excellent job. Paul Hastings should also be noted for its transactional proficiency; Samuel Waxman is an integral member of the emerging growth company, and M&A practices is a great option for life sciences and technology companies as they look to make deals.

Paul Hastings does a brilliant job of putting together high-functioning project teams comprising lawyers, scientific advisers and technical staff to oversee business-critical patent litigations and IP-rich transactions on behalf of global technology leaders. These teams are often international and bring together professionals in the United States, Europe and Asia, making the firm a premier destination for complex cross-border mandates. Pivotal to the success of the whole, Chicago-based Robert Unikel is held in the highest regard by the likes of Google, which he is representing extensively. With the support of local associates and New York-based partners and of counsel, he is leading the defence of Google (and Motorola Mobility) in a case brought by Arendi relating to mobile app patents; he is also defending it in nine separate cases brought by plaintiff Uniloc in the Eastern District of Texas regarding video encoding and streaming technologies; and is handling multiple cases in the Western District of Texas against VoiP-PAL.

He recently represented JSR Corporation against Cytiva Bioprocess in a dispute regarding protein A chromatography at the Federal District Court of Delaware. Hagiwara’s right-hand man, registered foreign lawyer Kyotaro Ozawa earned his stripes in New York courtrooms. Now, he leverages this experience to assist the US team in litigation against generic manufacturer on behalf of Johnson & Johnson-owned Actelion and Nippon Shinyaku, with regard to the treatment of pulmonary arterial hypertension. Together, Hagiwara and Ozawa are currently assisting Daiichi Sankyo in a complex, high-profile arbitration against Seattle Genetics.
