Joseph Samuel Grinstein

Joseph Samuel Grinstein is a highly experienced trial lawyer at Susman Godfrey LLP, concentrating his practice on high-stakes intellectual property disputes, including patent, trade secret, and tech-related antitrust cases. His work spans a range of complex technological areas, such as wireless networks (including Wi-Fi 6 standards), smartphone technologies, Field Programmable Gate Array (FPGA) devices, and self-driving car technology.

Grinstein frequently represents plaintiffs in patent infringement litigation, securing substantial jury verdicts. Notable plaintiff-side successes include a $166.3 million jury verdict (later totaling $181.2 million with interest) for Finesse Wireless LLC against AT&T Mobility and Nokia Corporation of America regarding wireless network patents, and a $37.5 million verdict for Atlas Global Technologies LLC in a patent infringement case involving Wi-Fi 6 routers against TP-Link Technologies Co. He also obtained a $31.5 million jury verdict for DataQuill Ltd. in a smartphone technology patent case against ZTE USA Inc. and a $15.4 million verdict (later $44 million with judgment) for PACT XPP Technologies, AG, against Xilinx, Inc. et al. While predominantly working on the plaintiff side, he also notably represented Uber in the widely publicized intellectual property and trade secret litigation initiated by Waymo concerning self-driving car technology, which settled during trial.

Based in Houston, Texas, Grinstein is a partner at Susman Godfrey LLP. While his case history demonstrates extensive experience in district court patent litigation, there is no public information to suggest he regularly appears in PTAB or IPR proceedings.

Grinstein earned his J.D. from Yale Law School, where he served as Managing Editor of the Yale Law Journal. He completed his undergraduate studies at Rice University, graduating summa cum laude with three majors. Following law school, he clerked for the Honorable Patrick E. Higginbotham on the U.S. Court of Appeals for the Fifth Circuit, and he has been admitted to the Texas Bar since 1997.
