Mr. Biddinger maintains a balanced practice, representing both plaintiffs and defendants, typically for industry-leading companies.

Key representations include obtaining a $1.1 billion verdict for the California Institute of Technology against Apple and Broadcom involving Wi-Fi error correction coding patents, a $250 million settlement for Transmeta Corp. in a microprocessor technology suit against Intel Corp., and a jury verdict of over $28 million for PureWick Corp. in a willful infringement case concerning external female urinary catheters. On the defense side, he secured a defense verdict of patent non-infringement, invalidity, and inequitable conduct for Gentex Corp. concerning automotive signal mirrors and successfully defended Samsung Electronics against multiple patent suits where the asserted patents were invalidated at the PTAB.

Mr. Biddinger possesses extensive experience in post-grant proceedings, including inter partes review (IPR) and ex parte re-examination at the Patent Trial and Appeal Board (PTAB). He has argued multiple times before the PTAB and is noted for coordinating patent office challenges effectively with ongoing district court litigation.
