Brian Paul Gearing is a partner in the New York office of Crowell & Moring and a member of the Intellectual Property Group, focusing on patent litigation. He has experience in all stages of litigation, from pre-suit investigations through appeal in numerous jurisdictions, and before the ITC. Dr. Gearing has also advised clients on portfolio management and adversarial patent licensing negotiations and has prepared invalidity and non-infringement opinions. He has unique experience working in Tokyo, Japan, where he spent three years representing Asia Pacific-based clients in U.S. litigations and arbitrations.

Dr. Gearing has been trial counsel on numerous high-profile litigations that have resulted in favorable judgments and settlements for his clients and has successfully examined witnesses and argued motions in connection with those litigations.

Dr. Gearing has substantial experience with a wide variety of technologies, including materials science, mechanics and dynamics of materials, cancer therapy, semiconductor and hard disk design and manufacturing, microprocessor technology, wireless communications, and networking equipment and architecture. He also counsels clients on the implementation of new technologies such as blockchain and distributed ledgers, and the development of innovative products such as virtual currencies and blockchain-based assets. Dr. Gearing is an author of fifteen scientific publications and a named inventor on two U.S. patents pertaining to implantable medical devices and friction and wear of novel nano-coatings (U.S. Patent Nos. 7,251,893 and 8,241,698).

Before law school, Dr. Gearing earned a Doctorate of Philosophy from the Massachusetts Institute of Technology, where his research focused on the mechanics and dynamics of materials with an emphasis on fracture of polymers, as well as mechanical testing at the micro- and nano-scales. During law school at U.C. Berkeley School of Law, Dr. Gearing was a member of the Berkeley Technology Law Journal and a fellow of the Berkeley Center for Law & Technology.

Prior Representative Matters

  • Represented Cisco Systems, Inc., including as trial counsel, before the ITC in two parallel investigations (Nos. 944 & 945) against Arista Networks, Inc. These cases have been the subject of hundreds of articles and continue to be closely watched by the entire networking industry.
  • Represented Cisco Systems, Inc., including as trial counsel, before the ITC in an investigation involving Conversant Intellectual Property Management, Inc. f/k/a MOSAID Technologies, Inc. and the assertion of six U.S. patents in the context of Power-over-Ethernet technology. The litigation settled on the eve of the ITC hearing. Also represented Cisco against Conversant in a related proceeding in the District of Delaware. Cisco’s assertion of racketeering (RICO) claims against Conversant in connection with the district court litigation attracted national attention, including in the Wall Street Journal.
  • Represented, including as trial counsel, Cisco and other suppliers of Internet wireless routing products in a complex multi-district litigation concerning patents alleged to pertain to 802.11-standardized wireless technology. After a seven-day bench trial, determined that the plaintiff’s damages claim was limited to a RAND rate of less than 10 cents for each accused Wi-Fi product and also found that plaintiff’s demands for damages of more than a billion dollars “lacked a credible methodology” and that the plaintiff’s case suffered from a failure of proof. The case was hailed as highly favorable to technology companies and consumers and received worldwide media attention, including in the IPLaw 360 articles “FRAND Rulings To Rein In Standard-Essential Patent Demands” and “Judge Sets Low Royalty Rate For Essential Wi-Fi Patents.”
  • Represented Cisco in an ITC investigation against ChriMar Systems, Inc. involving Power-over-Ethernet technology. Related proceedings are currently pending in the Northern District of California and Eastern District of Michigan.
  • Trial counsel for Intel Corp. against MicroUnity Systems Engineering, Inc. in the Eastern District of Texas in a patent litigation concerning microprocessor and memory controller architectures. The case settled shortly before trial.
  • Trial counsel for Israel-based Yeda Research & Development Co. Ltd. against ImClone Systems Inc. and Aventis Pharmaceuticals Inc. in a multi-billion dollar inventorship dispute in the Southern District of New York over a patent related to the Erbitux® (Cetuximab) cancer treatment drug. After a bench trial, received a total win with the court ordering a complete replacement of the named inventors on the patent-at-issue. The trial received worldwide attention, including press in the United States and Israel. See Practical Lessons from a “Made for TV” Patent Litigation: The Trial of Yeda Research and Development Co. Ltd. v. ImClone Systems Inc. and Aventis Pharmaceuticals Inc. The Federal Lawyer, 55(2), 51-55 (2008) (Groombridge, N. and Gearing, B.). The litigation ultimately settled on confidential terms minutes before oral argument at the U.S. Court of Appeals for the Federal Circuit.
  • Trial counsel for Shanghai-based Advanced Micro-Fabrication Equipment, Inc. against Applied Materials, Inc. in the Northern District of California in a trade secret misappropriation action involving semiconductor processing tools for etch and CVD. The case settled shortly before trial on confidential terms.
