Weil, Gotshal & Manges LLP‘s ’responsive and dedicated’ life sciences practice melds an active transactional life practice with a patent practice that covers both patent strategy and disputes before the PTAB and Federal Circuit Courts, working together to see through collaborations and licensing agreements in the sector. The firm’s efforts are spearheaded by patent litigators Elizabeth Weiswasser and Silicon Valley’s Edward Reines, who handle matters pertaining to biologics and small molecules among a range of other complex patent issues. Derek Walter, also based in Silicon Valley, is another name to note for patent litigation in the pharmaceuticals and biotech spaces. Transactions with a substantial IP element are overseen by Jeffrey Osterman and Charan Sandhu, who also advise on joint ventures and technology transfers. Lawyers mentioned are based in New York unless otherwise specified.
