ill Sigler drew his first breath within a mile of the site of the Boston Tea Party, the Old North Church, and Dorchester Heights. From his earliest days, Bill took to heart what these and other hallowed icons of the American Revolution symbolized: resiliency, ingenuity, and a burning desire to see justice done. Bill practices these ideals as a winning intellectual property trial and appellate lawyer for both plaintiff and defendant.

Bill has compiled an impressive array of jury trial victories over the course of his career. Most recently, Bill secured a jury verdict that Samsung had willfully infringed two patents on behalf of Imperium IP Holdings in a jury trial in the Eastern District of Texas, and followed that up with successful motions for treble damages of $20.9 million and attorney’s fees of $7.1 million. Bill also obtained defense jury verdicts in the Eastern District for defendants Barnes & Noble, Inc. and Gap, Inc. in patent infringement cases where the plaintiff sought $72 and $34.5 million in damages, respectively.

His other trial victories include patent infringement jury trial defense wins in the Eastern District of Texas for Pier 1 Imports and Thomas & Betts Corporation, and in the United States District Court for the Western District of Tennessee for Stored Value Solutions.

Appellate success is another hallmark of Bill's career. He's argued before the United States Court of Appeals for the Federal Circuit, and achieved victories in ten appeals he’s litigated before that court. These successes include winning appeals for, Blackhawk Network, Gap, Inc., and Papst Licensing.

As a result of his trial and appellate successes, Patexia has ranked Bill one of the top ten patent defense lawyers in the United States, Managing IP magazine IP World Handbook and Survey has named Bill an "IP Star," and Super Lawyers has selected him as a Washington, D.C. "Super Lawyer." And in an earlier decade of his life, Bill was named by Benchmark Litigation to its "Under 40 Hot List."

"Trial by jury is sometimes the best and only way to achieve justice," says Mr. Sigler. "I remain proud to be a part of this process."

Active in the intellectual property bar, as well, Bill previously served in the American Bar Association's Section of Litigation as co-chair of the Intellectual Property Committee's Patents Subcommittee.

Bill is also a published author, including the highly-read Section 298's Impact of Evidence at Patent Trials Thus Far in Law360. The media has also asked Bill to comment on intellectual property litigation issues, with publications such as The American Lawyer, Reuters, Bloomberg, Law360, and ABA Litigation News all having quoted him.

A devotee of all of Vincent Bugliosi's works, Bill challenges anyone to read Reclaiming History and believe anything other than Oswald was the culprit and that he acted alone.
