Bill Sigler is a winning intellectual property trial lawyer with jury trial victories for both plaintiff and defendant.

His trial successes include the firm's jury trial victories in the Eastern District of Texas. 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 Sherman. And in separate 2013 trials in Marshall, Bill obtained jury verdicts on behalf of defendants Barnes & Noble, Inc. and Gap Inc.

Bill also obtained two other verdicts for patent infringement defendants in the same Court, and a jury trial defense victory in the United States District Court for the Western District of Tennessee.

Bill’s trial and other successes have resulted in him being named an “IP Star” in Managing IP magazine IP World Handbook and Survey, and as a Washington, D.C. “Super Lawyer.”

"Trial by jury is often the best and only way to discover the truth, particularly through cross-examination," says Mr. Sigler. "I remain proud to be a part of this process."

Bill has also advocated at numerous claim construction and pretrial hearings, and provided winning oral advocacy on dozens of dispositive motions. Bill is also experienced in other facets of patent disputes, including declaratory judgment actions and reexamination and review practice at the United States Patent and Trademark Office.

Bill has spearheaded numerous appellate successes, achieving nine victories before the United States Court of Appeals for the Federal Circuit without a defeat.

Bill is active in the intellectual property bar, as well, currently serving 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, most recently authoring Section 298's Impact of Evidence at Patent Trials Thus Far in Law360. Bill is also asked 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.
