Brian, chair of the firm's IP Litigation/Patents Department and member of the Technology Oversight Committee, has been recognized as one of the leading intellectual property litigators in the nation. In March 2012, Benchmark Litigation recognized Brian as the Virginia Litigator of the Year. The American Lawyer selected him as its Litigator in the Spotlight in its November 2011 issue, and he was named Litigator of the Week in the September 16, 2011 issue of Am Law Litigation Daily. Most recently, he was selected as one of the 2011 Lawdragon 500 Leading Lawyers in America. He has been listed in Chambers USA as one of America's Leading Lawyers for intellectual property since 2004, and has been described by clients in that publication as a "top-notch litigator" and as a lawyer who "can find a solution when others cannot." He has also been recognized in Best Lawyers in America, as a Virginia Super Lawyer, and as one of Virginia's Legal Elite.

He has litigated patent and other intellectual property cases across the country, and has considerable experience in the Eastern District of Virginia, commonly known as the "rocket docket," a favorite venue for intellectual property litigants. Most recently, he was the lead trial lawyer for DuPont in its trade secret case against Kolon Industries. In that case, the jury awarded DuPont $919,900,000.

Brian was also the lead trial lawyer for Verizon Wireless and other wireless carriers in a patent infringement case brought by DNT LLC, a subsidiary of Acacia Research Corporation. The jury returned a verdict of non-infringement in favor of the wireless carriers, and also found the plaintiff's patent to be invalid.

Brian was also one of the lead trial lawyers in Verizon's patent infringement case against Vonage. In that case, the jury awarded Verizon $58 million, and the court entered an injunction against Vonage. After appeal, the case settled with a $120 million payment to Verizon.

Before starting his career in law, Brian spent an internship performing research in immunology, and was also a supervisor in the datacenter for a major Wall Street investment bank. He was an adjunct professor of law at the T.C. Williams School of Law. His experience also includes serving as law clerk to the Honorable Stephen V. Wilson of the U.S. District Court for the Central District of California.
