Prior to joining Irell, Thomas was a research assistant at Rice University. His research has focused on computer architecture and operating systems, specifically in the areas of high-performance computing, memory systems, robotics, and embedded systems. Thomas was the original maintainer of embeddedpython.org, an open-source Python environment for microcontrollers. He is an active member of the Association for Computer Machinery and a senior member of the Institute of Electrical and Electronics Engineers.

Thomas earned his Ph.D. in Computer Science and his M.S. in Electrical and Computer Engineering from Rice University. He earned his B.S. in Engineering and Music, with distinction, from Harvey Mudd College.

Experience

  • VLSI Technology LLC v. Intel Corporation (W.D. Tex). Served as the science advisor for the team that obtained a $2.2 billion jury verdict for VLSI Technology LLC in a suit against Intel Corporation. The matter involved two patents on technology used in Intel’s microprocessors.

  • Intel Corporation v. Future Link Systems LLC (D. Del.). Served as the science advisor for the team that obtained a settlement for Future Link Systems, resolving a patent dispute against Intel Corp. involving many hundreds of billions of dollars of microprocessors manufactured by Intel. In total, every one of Intel’s high-volume processors sold within the last eight years was accused of infringing multiple patents. Irell obtained favorable claim construction rulings, defeated two rounds of summary judgment motions and convinced the court to reject every one of Intel’s Daubert motions. With trial scheduled to begin in September, Intel had not managed to remove a single claim of a single patent from the case. In August 2017, after three years of litigation, Intel agreed to a confidential settlement.

  • MyMail, Inc. v. Conduit Ltd., Perion Network Ltd., et al. (E.D. Tex., PTAB). Served as the science advisor for the team that represented the defendants in patent litigation and related inter partes review involving patents related to browser toolbar technology. The case settled shortly before oral hearing in the inter partes review.

  • MyMail, Ltd. v. Yahoo!, Inc. (E.D. Tex.). Served as the science advisor for the team defending Yahoo! against patent infringement claims related to toolbar updating. The case settled in late 2017 on confidential terms.
