Robert C. "Chris" Bunt is a shareholder at the Tyler, Texas-based litigation boutique Parker, Bunt & Ainsworth, P.C., with a practice that includes significant experience in patent infringement litigation. His patent cases have primarily involved software, e-commerce, and telecommunications technologies. Based on his tracked case history, this includes matters related to digital advertising and cross-device user identification (Intent IQ, LLC v. Google LLC), in-vehicle control of mobile applications (Autonavigare LLC v. Volkswagen), and financial data processing. Mr. Bunt is an experienced trial attorney who has served as lead counsel in numerous jury trials and is frequently retained by national law firms to act as local counsel for cases filed in the U.S. District Court for the Eastern District of Texas.

The clear majority of Mr. Bunt's patent litigation appearances are on behalf of patent owners. With four of his five tracked cases on the plaintiff's side, his practice is heavily weighted towards asserting patents for patent licensing and enforcement companies. His clients have included entities such as Autonavigare LLC, Cyberfone Systems, LLC, and Intent IQ, LLC. His one tracked appearance for the defense was as local counsel for Bank of America in the sprawling and high-stakes litigation campaign brought by DataTreasury Corporation over its patents on electronic check and document imaging.

Mr. Bunt has been a shareholder at Parker, Bunt & Ainsworth, P.C. since 2005. One of his notable cases is Cyberfone Systems, LLC v. Discover Financial Services, Inc., where the patent-at-issue, related to processing data transactions from a telephone, was ultimately found invalid as an abstract idea by the U.S. Court of Appeals for the Federal Circuit. There is no record of Mr. Bunt having a public-facing practice before the Patent Trial and Appeal Board (PTAB) in inter partes review (IPR) or other post-grant proceedings.

Mr. Bunt earned his J.D. with honors from the University of Texas School of Law in 1993 and was admitted to the State Bar of Texas the same year.
