Lauren Dreyer is an intellectual property litigator at both the appellate and trial levels. Her practice concentrates on high-technology patent litigation in U.S. district courts, the International Trade Commission, and the U.S. Court of Appeals for the Federal Circuit. Lauren has litigated a wide range of technologies, including telecommunications, consumer electronics, medical devices, and other electronics and software-focused technology.

Lauren approaches trial from the perspective of an appellate advocate. She regularly counsels clients on difficult trial issues and strategic decisions at trial and on appeal. She is sought after for her ability to create prose that makes complicated and technical material easy to digest and compelling to the audience. She also has significant experience at the day-to-day demands of high-stakes litigation. She has marshalled cases from complaint through decision, developed discovery strategy, worked with technical and damages experts, argued at several hearings, and drafted numerous pre-trial and post-trial motions and dispositive briefs.

At the Federal Circuit, Lauren maintains an active docket, having served as appellate counsel of record in dozens of patent appeals. Some of her Federal Circuit experience includes representing numerous companies as appellees in invalidating patents on case-dispositive Section 101 grounds and arguing an issue of first-impression involving inter partes review proceedings and statutory interpretation of the America Invents Act.

Before joining Baker Botts, Lauren clerked for the Honorable Raymond T. Chen of the Federal Circuit, where she regularly assisted in the disposition of a wide range of intellectual property matters.

Lauren frequently lectures on intellectual property topics, including speaking at the Federal Circuit Bar Association's Bench and Bar, AIPLA, the Colorado Bar Association's Rocky Mountain Intellectual Property and Technology Institute, and the Cambridge IP Law Summer School. And from 2015-2019, Lauren taught legal writing at The George Washington University Law School.
