Joseph Mueller

Joseph Mueller is a highly accomplished patent litigator and Co-Chair of WilmerHale's firm-wide Trial Practice, specializing in high-stakes intellectual property disputes. He is recognized for his work across diverse technology areas, including telecommunications, display technology, retail, media, pharmaceuticals, and medical devices. Mueller's practice focuses predominantly on defending operating companies against patent infringement claims.

Mueller's extensive experience includes serving as a significant litigator for the defense in Phenix Longhorn, LLC v. AU Optronics Corporation et al., where WilmerHale secured a landmark patent litigation victory for AU Optronics (AUO) in January 2026. A jury in the Eastern District of Texas found AUO did not infringe any asserted patents and invalidated one of Phenix Longhorn's patents, marking the first time in over 22 years that a Taiwanese company obtained a defense verdict against an American company in the Marshall Division of the Eastern District of Texas. His notable achievements also include a significant trial victory for Intel Corporation in a $2 billion patent infringement suit and leading Apple's defense in Core Wireless Licensing v. Apple, which was recognized as a Top IP Defense Win. Since 2020, he has first-chaired trial teams in numerous cases involving billion-dollar stakes across various intellectual property disciplines. He also possesses considerable appellate experience, having argued before federal and state appeals courts, including the United States Court of Appeals for the Federal Circuit.

While WilmerHale's intellectual property practice encompasses post-grant proceedings, specific instances of Joseph Mueller regularly appearing in IPR or PGR proceedings are not explicitly detailed in publicly available professional profiles.

Mueller earned his B.A. with honors from Harvard College and his J.D. summa cum laude from Boston College Law School in 2001, the same year he was admitted to the Massachusetts bar. He also contributes to legal education as an adjunct professor of law at Boston College Law School, where he has taught patent litigation since 2011.
