Mark G. Knedeisen

Mark G. Knedeisen is a patent litigation attorney with extensive experience spanning high-stakes patent infringement lawsuits and Patent Office trials. His practice focuses on a diverse array of advanced technologies, including artificial intelligence and deep learning, cloud and database systems, network and data security, autonomous navigation, telecommunications, software, semiconductors, RF devices, optics, MEMS, and robotics. Case appearances, such as those involving Massively Broadband LLC and Samsung Electronics Co., Ltd., highlight his involvement in telecommunications and wireless technology patent disputes.

Knedeisen demonstrates a balanced practice representing both plaintiffs and defendants in patent disputes. While his tracked appearances show a slightly higher count on the defendant side (3 defendant, 1 plaintiff), his firm profile notes his role in securing a substantial US$750 million settlement for Carnegie Mellon University as a plaintiff. He is currently a partner at K&L Gates, where he has been involved in the majority of his tracked patent litigation cases. He previously appeared in a patent matter with Quinn Emanuel Urquhart & Sullivan.

A notable achievement in his career includes his role as part of the K&L Gates team that achieved a US$750 million settlement for Carnegie Mellon University in CMU v. Marvell Technology Group, following a favorable jury verdict and Federal Circuit affirmance. In addition, he successfully defended Carnegie Mellon University's patents in post-trial reexaminations related to that case. His recent case work includes representing both plaintiff and defendant interests in Massively Broadband LLC v. Samsung Electronics Co., Ltd. et al. and defending Massively Broadband LLC in Unified Patents v. Massively Broadband LLC.

Knedeisen possesses significant experience in Patent Office litigation, including Inter Partes Review (IPR) and ex parte reexaminations, regularly representing clients in both offensive and defensive proceedings before the PTAB. He has been recognized for his work in this area by Patexia's 2025 PTAB Litigation Report. He earned his J.D. from the University of Pittsburgh School of Law in 1998 (magna cum laude), an M.S.E.E. from Pennsylvania State University in 1993, and a B.E.E. from Villanova University in 1990 (cum laude). He is admitted to the Bar of Pennsylvania.
