David Enzminger

David Enzminger is a prominent patent litigator at Winston & Strawn LLP, where he co-chairs the Intellectual Property practice. He is primarily recognized for defending operating companies against patent infringement claims. His practice encompasses a broad range of technologies, including wireless network technology, Wi-Fi, and Near Field Communication (NFC).

Enzminger has achieved notable outcomes for his clients, demonstrating a focus on defense victories. He served as lead counsel for Samsung Electronics Co., Ltd. in CardWare Inc. v. Samsung Electronics Co., Ltd., a case initiated in the Eastern District of Texas concerning patents related to NFC wireless transactions. This litigation was paralleled by a Post-Grant Review (PGR) proceeding at the Patent Trial and Appeal Board (PTAB) where Samsung challenged CardWare's patents. Earlier in his career, Enzminger secured a complete defense victory for Belkin International Inc. against Fujitsu Ltd. in a patent infringement suit involving wireless network technology, where a jury found the asserted patent invalid. Winston & Strawn is frequently cited among "The Go-To Firms for Patent Suit Targets," reinforcing his defense-oriented practice.

His experience includes engagement with PTAB proceedings, as evidenced by the parallel PGR challenging patents asserted against his client, Samsung. Mr. Enzminger was admitted to the State Bar of California in 1988.
