Eric Lobenfeld's philosophy is to prepare each case as if it is going to trial. That puts the client in the strongest position to resolve the case, whether through settlement or through litigation to judgment.

Eric's work focuses on technology and life science intellectual property disputes. He has more than three decades of experience as a first-chair trial lawyer in patent, trademark, copyright, antitrust, unfair competition, and complex commercial cases. These include jury and non-jury trials in state and federal courts throughout the United States, as well as arbitrations and arguments in numerous state and federal appeals. He also handles post-grant review proceedings in the U.S. Patent & Trademark Office and has participated in Markman claim construction proceedings for more than 50 patents.

Eric represents companies in many industries, including computer hardware and software, pharmaceuticals and medical devices, bar code scanners and Radio Frequency Identification technology, Automated Teller Machines and web-enabled kiosks, semiconductor technology, television and motion picture technology, home and industrial lighting, and consumer electronics.

Eric is a regular panelist in the Practising Law Institute's annual two-day patent litigation program, where he has presented on expert issues and damages issues. He has also given a demonstration of a closing argument in a patent jury trial.
