Brian has tried patent infringement cases to jury verdict, argued Markman hearings, and argued before both the Federal Circuit and the PTAB. His cases have been featured in the Wall Street Journal, the New York Times, the Financial Times, the San Jose Mercury News, Politico, Law360, Patently-O, and IP Watch Dog. Brian has worked on cases involving legal issues of national importance, including two patent infringement cases resulting in landmark rulings by the U.S. Supreme Court.

Formerly a partner in the intellectual property group of an Am Law 100 law firm, Brian has represented clients in more than three hundred patent cases.

He also has experience in Section 337 investigations before the U.S. International Trade Commission. Brian has also litigated trademark, copyright, and defamation cases. He also has advised clients on licensing, portfolio reviews, litigation-risk analysis, and opinions.
