Debbie McComas has argued before the Texas Supreme Court, petitioned the United States Supreme Court, helped draft model patent jury charges for the Federal Circuit Bar Association, and defended foreign sovereigns from multiple continents. Whether before the highest courts or a trial court in rural East Texas, Debbie dedicates herself to her clients and brings practical solutions to uncommon problems.
Debbie has led teams in significant appeals and trial matters throughout the country. She argued In re Schmitz to the Texas Supreme Court, a case that set the standard for shareholder derivative suits against Texas corporations. Debbie defends foreign corporations and sovereign nations in cross-border disputes, often obtaining dismissal on jurisdictional grounds before discovery. Her extensive knowledge of both state and federal procedure and her ability to quickly grasp facts and legal issues allows her to aid her clients on a broad array of subjects, be it oil and gas or patent infringement.
Debbie is particularly active in the Federal Circuit Court of Appeals, where she has appeared in more than 25 cases, including appeals from both federal district court judgments and final written decisions from the PTAB.
A consummate advocate, Debbie is also dedicated to her community and is proud to have served as co-chair of Haynes and Boone’s Pro Bono and Public Service Committee. She also serves as a member of the Board of her church. She is honored to have received the Light of Justice Award from the Texas Defender Service for her pro bono achievements.
