The Patent 1000 focuses exclusively on patent practice and has firmly established itself as the definitive 'go-to' resource for those seeking world-class legal patent expertise.

Greenberg Traurig doesn’t place special emphasis on one or two aspects of patent practice but has mastered all trades. That is partly a function of its size – there are more than 100 USPTO-registered attorneys out of a total of 225 attorneys and professionals in its IP and technology group – but also of flexible management; people here are encouraged to pursue the work they are most enthused by, which has taken the firm into many niches. Special mention must be made of its litigation capabilities, when looking at GT through a New York lens; its local contingent includes several dynamic and experienced advocates, with Scott Bornstein, Joshua Raskin, Allan Kassenoff, Rose Cordero Prey, Richard Pettus and Jonathan Ball all standing out for their special qualities. Co-chair of the global patent litigation practice, Bornstein is a natural born leader who can get trial team members pulling in the same direction and performing at their optimum. Raskin also has a talent for energising and enthusing those around him; he chairs the New York IP department and serves as vice chair of the firmwide patent litigation group. He is in his element handling complex internet, software and electrical disputes and he pitches his tone and arguments perfectly whether in district courts or the PTAB. Kassenoff, who has tried multiple cases to verdict, has an agile technical mind and is comfortably at home litigating over high-technology and pharmaceutical patents. Likewise Prey, who “knows how to both manage and present a convincing case. She organises teams well and puts everyone in a position to succeed.” Like many of her colleagues, Prey is more than just a litigator; “She provides valuable insights on how best to structure IP programmes, manage risks and grow effective portfolios.” Pettus is one of the top life sciences experts on deck and has attained great results for a litany of well-known biopharmaceutical companies, as has Ball, an organic chemistry PhD with sophisticated litigation, prosecution, counselling and transactional skills. There’s a collaborative spirit to this group which sees them frequently – and very effectively – working together; for example, Ball and Bornstein have been representing Amneal in Hatch-Waxman litigation and Raskin and Kassenoff have gone in to bat for Rakuten against IBM in a tussle over internet-related patents. The group is well integrated across offices, too; Ball and Prey are part of a team spanning New York, Los Angeles, Orange County and Boston that is supporting a biopharmaceutical company developing next-generation cellular immunotherapies for cancer and immune disorders.
