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 interested in understanding existing IP litigations and IP law. Mr. Cohen also 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.

Prior to his legal career, Mr. Cohen gained extensive professional experience in numerous technology areas, including 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.
