John Flock is a high-stakes patent litigator whose experience has generated professional achievement awards and repeated American Law Journal "Top Jury Verdict" recognition. He combines more than 20 years' patent litigation experience with nine years of service as a former New York City Assistant District Attorney to litigate intense legal battles arising in the most popular forums for patent litigation, including the ITC and district court. Mr. Flock is a member of Kenyon's Executive Committee and is co-chair of the firm’s Electrical/Mechanical/Computer Practice Group.

Mr. Flock's effectiveness in client advocacy is anchored by his technical education and expertise and the trial techniques that he teaches to peers in litigation skills training courses. He is particularly effective in representing technology and electronics companies because he holds an undergraduate degree in physics and possesses computer technology expertise resulting from experience designing and implementing computer programs, supervising computer programming staff, and serving as court-appointed receiver for a software company. As a result of his expertise in trials and technology, Mr. Flock was recently chosen as the lead outside lawyer for Sony Corporation against LG Electronics on five high-profile U.S. litigations (including two ITC cases) and advises on Sony's litigation strategy in five European and Asian countries.

Recognized as a leading patent lawyer by Legal 500 and Benchmark, Mr. Flock is also a frequent writer and speaker on intellectual property issues. Beside his work with professional organizations, he has authored a chapter on winning strategies for IP litigation for a Thompson/Charles River Media book, is writing on global IP litigation strategies for a West book and, unique among patent litigators, has been interviewed twice on Entertainment Tonight.
