Clients rely on the excellent judgment and efficient management style that Mr. Flanagan has honed through years of practice, and trust that he will persuasively marshal the facts and the law to successfully resolve their most complex and important matters.

Mr. Flanagan’s investigations and courtroom skills have their roots in his tenure as an Assistant United States Attorney (AUSA) in the Central District of California, where he prosecuted cases involving, among other things, bank fraud, federal program fraud and official corruption.

As he has advised these companies, Mr. Flanagan has also become an accomplished intellectual property litigator, and is regularly recognized as one of the top IP litigators in California.

Here too, Mr. Flanagan’s success springs in large part from his ability to take a tough case to trial. His IP litigation experience has included representation of clients in the software, semiconductor, telecommunications and medical device industries and spans patent and copyright infringement, trade secret misappropriation, Lanham Act and licensing disputes.
