Attorney Derek Gilliland

Areas of Concentration

Derek Gilliland focuses on trying cases. While he oversees the firm’s intellectual property litigation practice, Derek handles all types of civil lawsuits including personal injury, products liability, and breach of contracts.

In 2010, he was a key member of the trial team that obtained a $27,000,000 verdict for DataTreasury. The verdict was later enhanced to $54,000,000 for willfulness and ultimately settled on appeal.

In 2013, Derek was co-lead trial counsel for the team that obtained a $95,795,507 verdict in federal court in Tacoma, Washington for Syntrix Biosystems. This is the largest patent infringement verdict in the State of Washington and was the 20th largest verdict in the United States during 2013 according to ALM. The verdict was settled on appeal for $70,000,000.

Derek has successfully argued before the Texas Supreme Court on behalf of a personal injury plaintiff 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.
