Craig S. Summers

Craig Summers is a dedicated, life-long IP attorney with over 35 years of experience and the praise of his peers as “an outstanding litigator.”  His practice focuses on intellectual property litigation and dispute resolution, including patents, trademarks, trade secrets, copyrights, and unfair competition.  With a strong and diverse technical background, he is able to explain complex technology in simple terms that are easily understood.  This has allowed him to successfully represent clients through jury trials, bench trials, and appeals, and to achieve his clients’ goals before trial through motion practice, settlement and other means.

Over the years, Craig has litigated hundreds of intellectual property cases in district courts throughout the United States, the ITC, the PTAB, and the TTAB.  He handles a wide range of technologies, from the highly complex to the simplest of inventions.  Representative technologies include computer software and hardware, wireless communication, GPS navigation, e-commerce, aircraft equipment and components, medical devices, dental products, pharmaceutical products (and related Hatch-Waxman litigation), apparel, and athletic equipment.  Representative clients include Rolex Watch U.S.A., Edwards Lifesciences, TCL Communication Technology Holdings, TCT Mobile, Toshiba Corporation, HTC America, Alpine Electronics, Winn Incorporated and lululemon.

In addition to his litigation practice, Craig has extensive experience advising clients regarding intellectual property infringement and validity issues, and he has been able to successfully resolve many disputes for his clients without litigation, either through informal pre-litigation negotiations or through formal ADR, such as mediation and arbitration.  His diverse practice also includes representing several foreign corporations, which makes him especially qualified to navigate the unique issues facing those companies in U.S. litigation.  He also has been retained as an expert witness in business disputes and litigation where patent law is an issue.

Earlier in his career, in addition to his litigation practice, Craig was the lead attorney responsible for preparing and prosecuting patent applications for many well-known innovators, such as the Walt Disney Company.  During that time, he was responsible for obtaining patents related to many of Disney’s most famous amusement park attractions and technologies.  Although he no longer prepares or prosecutes patent applications, his prior experience has proven to be a very useful resource in litigating patent infringement cases.

Active in Knobbe Martens’ law firm management, Craig has served several terms on the firm’s Executive Committee and Diversity Committee.  He is currently serving as a member of several firm committees, including the firm’s Litigation Committee, Data Privacy and Security Committee, and Mentor Committee.  He also serves as pro bono counsel for the Downtown Women’s Center in Los Angeles and has worked on pro bono litigation in connection with the Central District of California’s Pro Bono Civil Rights Panel, which provides opportunities to represent pro se litigants in prisoner civil rights cases in Federal District Court.
