Sean is Co-Chair of the firm’s National Intellectual Property Litigation Practice and Co-Managing Partner of the San Francisco office. Sean is a trial lawyer with extensive experience in litigating patents, trade secrets, copyrights and other intellectual property in “bet the company” cases on behalf of both plaintiffs and defendants.
Sean was the lead trial counsel for Varian Medical Systems in a global patent litigation dispute against its primary competitor Elekta involving numerous patents on cancer treatment technologies across numerous jurisdictions including the International Trade Commission, District of Delaware, Northern District of California, Germany and United Kingdom. Sean and his team were able to obtain a highly favorable settlement for Varian, after an ITC victory on behalf of Varian in which Elekta was found to infringe multiple, valid patents owned by Varian.
Sean was one of two lead counsel for plaintiff ViaSat in a complex patent and contract breach case against Space Systems/Loral involving broadband satellites, which resulted in a jury verdict of $283 million for ViaSat in the Southern District of California. In 2014, Sean won “Milestone Case of the Year” at the Managing IP North America Awards for his ViaSat jury verdict. Sean also won Top Verdict of 2014 by The National Law Journal, Top 10 Plaintiff Verdict by Dollar by the Daily Journal, and Top California Verdict of 2014 by The Recorder, achieving the highest dollar amount across all categories.
Sean also obtained a complete defense verdict as trial counsel in a multi-patent jury trial in Delaware on behalf of Symantec, defeating a claim for damages exceeding $1 billion. Sean was also trial counsel on behalf of defendant Samsung Electronics in the second “smartphone” patent trial brought by Apple in the Northern District of California, in which all Apple patents defended by Sean and his team were found to be not infringed and Apple received less than six percent of its damages claim on the remaining patents defended by the Firm.
At the International Trade Commission, Sean has served as trial counsel for respondent HTC in the ITC investigation (337-TA-710) initiated by Apple, and trial counsel for respondents NVIDIA, Broadcom, STMicroelectronics, MediaTek, Cisco, and Motorola in the ITC investigation (337-TA-753) initiated by Rambus. In both cases involving billions of dollars in product sales, the ITC Commission found no violation for all claims defended by the Firm. In addition to trial victories, Sean has secured dispositive summary judgment victories for his clients in various venues, including the Eastern District of Texas, the Northern District of California, the District of Delaware and the Western District of Washington.
