Brian Lebow

Brian Lebow is a patent litigator with a practice focused on defending high-tech companies against claims of infringement and trade secret misappropriation. He is currently an associate in the Intellectual Property Practice Group at Sheppard Mullin in New York. His prior affiliations relevant to patent litigation include Ropes & Gray and Gibson, Dunn & Crutcher. Lebow’s experience spans various high-tech sectors, including telecommunications, semiconductors, displays, and automotive technology, with a particular emphasis on standard-essential patents (SEPs), such as those related to Wi-Fi and 5G.

Lebow primarily represents defendants, as evidenced by his appearances for Keysight Technologies and Apple Inc. in tracked cases. His work includes defending clients in complex multi-forum disputes. For instance, he appeared for Keysight Technologies in Centripetal Networks, Inc. v. Keysight Technologies, Inc. et al., a case involving network threat detection patents where Keysight achieved significant success in invalidating many asserted claims through PTAB proceedings and Federal Circuit appeals. He also represented Apple Inc. as counsel in Cobblestone Wireless LLC v. Apple Inc., a patent infringement suit brought by an NPE. An Inter Partes Review (IPR) initiated by Apple against Cobblestone Wireless in that matter was discretionarily denied in early 2026.

His practice encompasses all stages of litigation in federal district courts, PTAB proceedings, and appellate matters. Lebow’s experience with the Federal Circuit is further underscored by his previous service as a judicial clerk for the Honorable Todd M. Hughes on the U.S. Court of Appeals for the Federal Circuit.
