DLA Piper LLP (US) demonstrates particular strength in complex cross-border disputes involving the US as a key international patent venue. With expertise in district courts, the Federal Circuit, the ITC and the PTAB, the practice offers the full range of litigation skills thanks to its deep bench of first chair trial lawyers and often acts in matters involving several domestic venues. Many international and US giants from a diverse sector range rely on the practice’s expertise, including technology, electronics, consumer products, semiconductor and automotive clients. Increasingly, the group also acts for clients from the media and entertainment sector. In 2019, the firm grew its Hatch-Waxman practice with the arrival of Michael Sitzman, formerly of Gibson, Dunn & Crutcher LLP, and Soumitra Deka, formerly of Arnold & Porter, in the San Francisco office. In New York, Tony Pezzano and of counsel Michael Dougherty from Hogan Lovells US LLP also bolstered the life sciences bench. Further strategic changes were the arrival of patent and trade secret litigator Michael Jay from Boies Schiller Flexner LLP in Los Angeles and the strengthening of the firm’s technical expertise in artificial intelligence, machine learning and blockchain matters with the recruitment of former McDonnell Boehnen Hulbert & Berghoff LLP practitioner Lisa Hillman to the Boston office. The arrival of former Nixon Peabody LLP patent experts Maria Swiatek and Christopher Mooney in the Silicon Valley office and the recruitment of former Venable LLP life sciences specialist Michael Furrow were another key events.
