Christopher Dryer

Christopher Dryer is a Principal at Fish & Richardson, where his practice is concentrated on patent litigation and appeals across various U.S. venues, including District Courts, the U.S. International Trade Commission (ITC), and the U.S. Court of Appeals for the Federal Circuit. His technical experience spans a wide array of technologies, such as network protocols, flash memory, lithium-ion batteries, streaming video, fiber optics, mobile electronic devices, semiconductors, and software. Prior to his legal career, he worked as a consultant specializing in software engineering, focusing on object-oriented programming and relational databases.

Dryer primarily represents operating companies on the defendant side in patent infringement disputes. His tracked case appearances are exclusively in defense of companies like Samsung Electronics Co., Ltd. and Microsoft. He also possesses significant experience with inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB), notably including a case where a successful IPR challenge led the ITC to set aside remedial orders related to the invalidated patent.

His patent litigation experience includes cases such as RFCyber Corp. v. Samsung Electronics Co., Ltd. et al., which involved contactless payment methods, and Proxense, LLC v. Microsoft. In connection with the Proxense v. Microsoft litigation, multiple IPR proceedings (e.g., IPR2024-00407 and IPR2024-00573) saw claims found unpatentable under 35 U.S.C. § 103 by the PTAB in July and August 2025.

Dryer earned his J.D. magna cum laude from Georgetown University Law Center in 2011, where he was an Article Editor for The Georgetown Law Journal. He holds a B.S. in Computer Science from the University of Mary Washington (2004). Following law school, he served as a law clerk for the Honorable Timothy B. Dyk of the U.S. Court of Appeals for the Federal Circuit from 2012 to 2013. He is admitted to practice in the District of Columbia.
