Charles L. "Chip" Ainsworth

Charles L. "Chip" Ainsworth is a principal at Parker, Bunt & Ainsworth, P.C., a boutique litigation firm based in Tyler, Texas. His practice focuses on patent litigation, alongside business litigation and personal injury matters. The firm has extensive experience in the U.S. District Court for the Eastern District of Texas, where it acts as both lead trial counsel and local counsel for other national law firms. The firm's patent case experience spans a variety of technologies, including semiconductors, medical devices, software, and oil and gas equipment.

Based on his tracked appearances, Ainsworth's patent litigation practice is exclusively focused on representing patent holders on the plaintiff side. In his representative cases, he has asserted patents on behalf of non-practicing entities (NPEs). For instance, he served as lead counsel for Autonavigare LLC, an entity asserting patents related to in-vehicle infotainment systems that control mobile device applications. He also served as local counsel for Greenthread, LLC, another patent assertion entity, in litigation involving patents on fundamental semiconductor technology, specifically devices with "graded dopant regions."

Ainsworth’s work has intersected with Patent Trial and Appeal Board (PTAB) proceedings. Notably, district court litigation involving Greenthread LLC was stayed pending the outcome of inter partes review (IPR) petitions filed against the asserted patents. There is no publicly available information indicating that Ainsworth himself has a practice appearing before the PTAB. No notable verdicts or published settlements were found in connection with his tracked cases against Volkswagen or STMicroelectronics.

Ainsworth earned his J.D. from the South Texas College of Law in 1992 and a B.A. from Texas Tech University in 1985. He was admitted to the Texas bar in 1992.
