Prior to his retirement from the bench, Judge Davis saw the Eastern District’s patent docket grow to one of the largest in the country. He personally handled over 1,700 intellectual property cases and managed one of the nation’s busiest patent dockets. He also conducted as many as 11 patent jury trials in a 12-month period and more than 250 individual Markman hearings.

Several of Judge Davis’ cases have become landmark decisions from the U.S. Court of Appeals for the Federal Circuit and the U.S. Supreme Court. His rulings on the bench enjoyed a high affirmance rate. He previously served by invitation on both the Federal Circuit and U.S. Circuit Court of Appeals for the Fifth Circuit. He also has served on the 5th Circuit judicial council, the Federal Circuit advisory committee on case management, and as co-chair of the federal judges committee of the Federal Circuit Bar Association.  In August 2015, Judge Davis was appointed by Chief Judge Sharon Prost to serve a three-year term on the Federal Circuit’s advisory council.  And, in April 2016, Judge Davis was honored with the New York Intellectual Property Law Association’s “Outstanding Public Service Award” for his significant contribution in intellectual property law.

Before his appointment to the federal bench, Judge Davis served as chief justice of Texas’ 12th Court of Appeals. Prior to his service as a judge, he was an active trial lawyer for 23 years. His experience as a practicing attorney includes a variety of complex cases, including commercial, oil and gas, will and estate contests, breach of fiduciary duty, medical malpractice, products liability and negligence.
