Craig N. Tolliver is a seasoned patent litigation attorney with over two decades of experience in intellectual property and complex litigation matters. Based out of Charhon, Callahan, Robson & Garza (CCRG), a Dallas-based intellectual property and commercial litigation boutique, Mr. Tolliver focuses on patent litigation, enforcement, IP portfolio strategy, and detailed licensing negotiations. Before joining CCRG, he was a Shareholder at McKool Smith for over eleven years.

Mr. Tolliver’s practice encompasses a broad spectrum of technologies, including software, hardware, medical equipment, semiconductor industries, financial technologies, mobile devices, Internet communications and protocols, and e-commerce. While his recent tracked appearances show a lean towards defendant-side representation (4 of 5 cases), his overall practice includes both defending and prosecuting patent infringement suits for clients ranging from large corporations to small startups. Notable representations include Apple in a Delaware patent suit concerning power management, BMC Software against ServiceNow in Texas over IT discovery technologies, and PanOptis Wireless Technology in Texas suits regarding LTE standard-essential patents. He also represented co-plaintiffs MagSil and MIT in a Delaware patent case involving read-head technology.

Mr. Tolliver is active in proceedings before the Patent Trial and Appeal Board (PTAB), as evidenced by his appearances in IPR2022-00135 and IPR2020-01266. He has represented NordVPN in both offensive and defensive patent infringement suits, including related proceedings before the USPTO and PTAB. In a prominent matter, while his client Teso LT, UAB (Oxylabs) was found by a jury to have willfully infringed Bright Data's patents in a district court case, Mr. Tolliver was involved in a related Federal Circuit appeal (23-2443, Bright Data, Ltd. v. Code 200, UAB et al.) where the defendants successfully defended an unpatentability finding for a Bright Data patent, resulting in an appellate win.

He is licensed to practice in Texas and Colorado, and before the United States Patent & Trademark Office. Mr. Tolliver earned his J.D. from Vanderbilt Law School in 2000 and holds a B.S. in Microbiology from the University of Florida (1995).
