In this episode I speak with Andrew Trask, a Partner at Williams & Connolly LLP in Washington D.C. where he practices patent litigation. Andrew has played practically every professional role in the patent process. He started his career as a scientist/chemist where he was the co-inventor on a number of patents. He then went on to work as a non-lawyer Patent Agent at a large law firm in New York City while he completed law school at night. After graduation he clerked on the Federal Circuit (the federal court of appeals responsible for hearing patent appeals) and then after a few years at Williams & Connolly as a patent litigator he moved in-house to work at Google. He returned to the firm several years ago where he was just elected to the partnership this year.In our conversation, we discuss his path from scientist to lawyer, what it was like to simultaneously work as a big law patent agent and complete law school at night, the unique nature of practicing before the federal circuit, the differences of working in-house and at a private law firm, and some tips and tricks to succeed as a patent litigator. Sign up for future episodes at howilawyer.com or wherever you get your podcasts (pod.link/howilawyer).
