Paul Hastings is highly recommended in New York for patent litigation, supported by its high level of activity in the life sciences sector.

Key practitioners in the New York office include Eric Dittmann, Chad Peterman, Preston Ratliff and Bruce Wexler. Wexler is a life sciences patent litigator in the IP group, serving as the firm’s industry leader for the area.

The firm was also active in Hatch-Waxman disputes, including a case for Merck against Teva that involved its branded Entereg product. Additional patent clients include Adamas Pharmaceuticals, Sunovion, Allos Therapeutics, Amgen, Orexigen, Google, Zimmer Biomet and Helsinn Healthcare.
