Derek Gilliland handles all manner of complex litigation. For the last several years he has focused on intellectual property and oversees the firm’s intellectual property litigation practice, which primarily operates out of the firm’s Dallas office. Derek has been an instrumental member of the trial teams for the firm’s two biggest intellectual property verdicts.

In 2010, he was a key member of the trial team for DataTreasury in its trial against US Bank, which resulted in a large verdict that was significantly enhanced by the court based on a finding that the patent at issue was willfully infringed. DataTreasury Corp. v. U.S. Bank N.A., No. 2:06-cv-72-DF (E.D. Tex. March 26, 2010).

In 2013, Derek was the lead trial lawyer for the team that obtained a $95,795,507 verdict for Syntrix against Illumina in federal court in Tacoma, Washington. This verdict is the largest patent infringement verdict in the State of Washington, and it was settled on appeal for $70,000,000. Derek and the Nix Patterson team were assisted at trial by lawyers with Bracewell & Giuliani. Derek’s Syntrix verdict was the 20th largest verdict in the United States during 2013 according to ALM. Syntrix Biosystems Inc. v. Illumina Inc., No. 3:10-cv-05870-BHS (W.D. Wash. March 14, 2013).

Derek has carried his skills beyond the trial courts by successfully arguing before the Texas Supreme Court in the case of Daughters of Charity Health Services of Waco v. Linnstaedter, 226 S.W.3d 409 (Tex. 2007).

Derek is a frequent seminar speaker for the Texas State Bar, AIPLA, and other professional organizations.

Derek focuses his practice on all types of complex litigation including patents, trademarks, copyrights, trade secrets, general commercial Litigation, and products liability.
