He served as Founding President of the Eastern District of Texas Bar Association and the Judge Paul Brown Inn of Court. He also was heavily involved in the New York Intellectual Property Law Association, the Sedona Conference, and the Leahy Institute of Advanced Patent Studies. He was also a member of the delegation of attorneys and judges that presented the first patent mock trial at Beijing University in China in 2012, where he delivered a presentation on U.S. trial practices at Southwestern University School of Law and Political Science in Chongqing, China. Clyde served as the current Chairman of the Bench Bar Conference of the Eastern District of Texas and as Chairman of the Advisory Committee for the Institute for Law and Technology of the Center for American and International Law in Plano (formerly Southwestern Legal Foundation).
As he did in the legal arena, Clyde made a profound impact in public affairs. He was a Texas Elector in 2000, serving as a member of the Presidential Electoral College in one of the closest presidential races in American history. Clyde also served by way of Gubernatorial appointment as Chairman of the Grayson County Regional Mobility Authority, Commissioner of the Red River Interstate Compact Commission, Member of the Board of Directors for the Red River Authority of Texas, and as Commissioner of the Red River Boundary Commission, where he played a key role in resolving the long-time boundary dispute between Texas and Oklahoma. Clyde also holds the unique distinction of being named as Conservator of the Riverbend Water Resources District by the 82nd Texas Legislature, helping settle a decades-long legal battle over water issues in East Texas and Southwest Arkansas. Serving as Grayson County Republican Chairman for more than ten years and on the State Republican Executive Committee, Clyde played a pivotal role in the transition of both Grayson County and the state of Texas from Democrat to Republican-held majorities. Though a life-long conservative, Clyde was also respected for working across the political aisle when it served the public interest.
