He currently serves as lead post-grant counsel to some of the world’s best-known innovators and has handled some of the most noteworthy PTAB trials to date, including the only precedential decision on live testimony. Moreover, he was named by Managing IP as its “Outstanding PTAB Litigator” in 2020.

Prior to becoming an attorney, Scott worked as an electrical engineer for a government agency, troubleshooting embedded systems and circuit designs.
