Paul Hastings LLP has 'a deep bench' of lawyers, who combine 'exceptional technical expertise and a great strategic approach'. The 'very dedicated' team is a go-to-practice for PTAB litigation, especially for petitioners; it is primarily active in life sciences litigation, especially in pharmaceuticals and biotechnological cases, but is also instructed by clients in the technology and telecoms industries. A recent success was the defense of Trend Micro against Intellectual Ventures in a Federal Circuit case in which co-chair Yar Chaikovsky from Palo Alto secured a rare grant for attorney's fees from the court, winning the full $441,000 for the client. Together with his Washington DC-based co-chairs, Joseph Palys and Naveen Modi ('a top-notch advocate') Chaikovsky obtained an affirming decision from the Federal Circuit on behalf of HTC in a consolidated case against Virginia Innovation Sciences and Amazon, obtaining dismissal of over 360 claims covering eight patents as ineligible. Helsinn Healthcare, Boehringer Ingelheim and Sumitomo Dainippon Pharma are also among the team's clients. Eric Dittmann and Joseph O’Malley in New York impress with their 'passion, dedication, experience' and 'amazing ability to master the nuances and complexities of cases'. Other key figures include Washington DC's Jeff Pade and Blair Jacobs, Bruce Wexler and of counsel Young Park in New York. Robert Unikel and of counsel Robert Laurenzi joined from Arnold & Porter in Chicago and New York respectively, and David Beckwith joined from Fitzgerald Knaier LLP. Palo Alto's Philip Ou made partner. Gerald Flattmann and Evan Diamond left for King & Spalding LLP, while Michael Hendershot joined Jones Day and Hassen Sayeed joined O'Melveny & Myers LLP.
