Mr. Oussayef has significant trial experience. He recently second-chaired IBM’s first trial as a patentee in decades, helping secure an $82.5 million jury verdict on behalf of IBM. Leading up to trial, Mr. Oussayef successfully argued dispositive issues involving claim construction, patent eligibility, and infringement. At trial, Mr. Oussayef examined IBM’s technical expert and cross-examined three of Groupon’s witnesses, including Groupon’s technical expert. The two-week trial resulted in a finding of willful infringement on all four patents-in-suit.
Mr. Oussayef has extensive experience managing all aspects of technology cases. He represented LifeCell Corporation against TELA Bio, Inc. in a trade secret and unfair competition case involving surgical mesh products, where he defended and deposed dozens of witnesses across the country before the case settled. He also defended Cisco, ARRIS, Time Warner Cable, and several other technology companies in patent infringement actions involving 29 patents asserted by a non-practicing entity, Rockstar, created by Apple, Microsoft, Ericsson, Sony, and Blackberry. In that case, Mr. Oussayef managed a team of attorneys from several law firms engaged in simultaneous district court actions and patent office proceedings.
Mr. Oussayef is active in the firm’s pro bono and attorney development efforts. Mr. Oussayef has helped expand Desmarais LLP’s pro bono practice and has served as pro bono counsel in matters involving political asylum and not-for-profit intellectual property licenses. Mr. Oussayef co-directs the firm’s trial training program, where Desmarais LLP associates have the opportunity to run a multi-day mock trial, with partners acting as judges, actors acting as witnesses, and volunteers acting as jurors.
Mr. Oussayef earned his law degree from Boston University and studied computer science as an undergraduate at the University of Rochester, where he focused on artificial intelligence. He was president of the debate team, where he was an Academic All-American and competed against schools from across the country. His decision to pursue technology litigation arose from combining those interests.
Before joining Desmarais LLP, Mr. Oussayef was an associate in the Intellectual Property Group at Ropes & Gray LLP.
