Thomas Victorino DelRosario

Thomas Victorino DelRosario is a patent litigation attorney with a practice focused on intellectual property disputes, particularly in the technology sector. He is currently counsel at Susman Godfrey.

Mr. DelRosario's experience includes handling complex patent infringement cases for plaintiffs. His sole tracked case, Cortex MCP, Inc. v. Visa, Inc., involved representing a plaintiff patent owner (identified as a non-practicing entity) in a dispute concerning patents related to next-generation mobile-wallet platforms and tokenization technology, including file formats for credential storage and verification. This suggests a specialty in software, financial technology, and mobile technology, aligning with his background in electrical engineering.

In the Cortex MCP, Inc. v. Visa, Inc. matter, the district court case was stayed pending the resolution of inter partes review (IPR) proceedings initiated by Visa challenging the asserted patents. These IPRs have resulted in several claims of the patents-in-suit being found unpatentable. Before joining Susman Godfrey, Mr. DelRosario was a senior attorney at AZA Law (Ahmad, Zavitsanos & Mensing), where he also focused on intellectual property litigation.

Mr. DelRosario holds a J.D. from Arizona State University College of Law, awarded cum laude in 1999, where he served as a Managing Editor for the Arizona State Law Journal. He earned his B.S. in Electrical Engineering from the University of Maryland in 1994. He is admitted to practice in the State Bars of Texas, Arizona, and California, and is also admitted to the U.S. Patent and Trademark Office and the U.S. Court of Appeals for the Federal Circuit, among other federal district courts.
