Alyssa represents companies in all stages of litigation — from pre-suit investigation, through trial, and on to appeals court. In 2023 alone, she was a key member of Orrick teams that won two jury verdicts, three ITC proceedings, and numerous IPRs and dispositive motions.

She also has experience in litigation under the Hatch-Waxman Act, successfully defending generic challenges to patents protecting blockbuster medical therapies. Most recently, Alyssa has been involved in both litigation and counseling involving the legal questions raised by the rapid growth of AI.
