Jayson Cohen is an associate in the firm’s Intellectual Property Group. Mr. Cohen focuses his practice on patent litigation and other intellectual property litigation and counseling.

Mr. Cohen has extensive experience in all stages of IP litigation—from pre-filing investigation, the pleading stage, and preliminary injunction practice to discovery and trial—as well as extensive experience negotiating and drafting settlements. He has represented clients before numerous U.S. District Courts, the New York Supreme Court, the U.S. International Trade Commission, and the U.S. Copyright Royalty Board in patent infringement, IP licensing, and trade secret disputes. These disputes have spanned a wide variety of technologies, such as:

  • Electronics, Optics, and Semiconductors: semiconductor devices and their fabrication, semiconductor lasers, light emitting diodes, digital cameras, circuit bus architecture and arbitration, power management of processors, computer memory
  • Life Sciences: pharmaceutical products (in ANDA litigation under the Hatch-Waxman Act), monoclonal antibodies, medical devices and technology 
  • Chemistry and its Uses: catalyst systems to abate diesel engine emissions, genetically modified crops and plant gene markers, chemical synthesis and use of pesticides, cosmetic formulations
  • Software-Based Technologies: e-commerce, web sites, web-based maps, electronic trading algorithms

Beyond his work in litigating IP disputes, Mr. Cohen has served as IP litigation counsel for transactional matters, such as acquisitions and securities offerings, and he has counseled corporate clients and hedge funds interested in understanding existing IP litigations and IP law.

Prior to his legal career, Mr. Cohen gained extensive professional experience in numerous technology areas, which he uses in his IP practice. These technology areas include electronics, optics, physics, communications, networks, cryptography, chemistry, mechanical devices, and software. He worked as a scientist at MagiQ Technologies, Inc. from 2000 to 2001, where he also acted as the liaison with outside counsel on patent and regulatory issues. From 2001 to 2004, he worked as a senior engineer at The MITRE Corporation. In addition, Mr. Cohen was a visiting scientist at New York University in 1999 and at the National Science Foundation FOCUS Center at the University of Michigan from 2004 to 2006. Mr. Cohen is also an inventor on two patents, one concerning efficient random number generation using optical detection and one concerning wavevector-division multiplexed optical communications and quantum cryptography.

Mr. Cohen writes regularly on IP-related topics. He authored the chapter “Settling Patent Cases” in a leading treatise on the law of settlement agreements and the settlement process, Settlement Agreements in Commercial Disputes: Negotiating, Drafting and Enforcement. He was a Contributing Editor of another leading treatise, Trade Secrets, for which he focused on developments in the law of misappropriation of trade secrets. Furthermore, Mr. Cohen has served on the Publications Committee of the New York Intellectual Property Law Association (NYIPLA) since 2013. For NYIPLA’s bi-monthly publication, The Report (formerly Bulletin), he writes a regular feature entitled “IP Media Links.”

In 2015, Mr. Cohen was named a BTI Client Service All-Star by corporate counsel in recognition of his excellence in client service, one of only 354 lawyers and 25 IP lawyers named nationally. From 2012-2015, he was selected by Super Lawyers to the New York-Metro Rising Stars list for Intellectual Property Litigation.

Mr. Cohen earned a Sc.B. in electrical engineering and an A.B. in history magna cum laude from Brown University, where he was elected to Tau Beta Pi. He received his Ph.D. in applied physics from the University of Michigan, where he was a Regents Fellow and a Rackham Pre-Doctoral Fellow. He received his J.D. magna cum laude from the University of Michigan Law School, where he served as a contributing editor of the Michigan Law Review and was elected to the Order of the Coif.
