He is a lawyer, engineer, arbitrator, businessman, and an adjunct engineering and economics professor at Rice University.

“We are thrilled to welcome someone with the vast patent and intellectual property experience of David Warden.” says John Zavitsanos, a founding partner of AZA. “He provides a valuable engineering background and has not only tried these cases, but has overseen them as a special master.”

Mr. Warden has been appointed as special master and mediator by federal courts in various patent litigation matters. He is licensed as a patent attorney before the U.S. Patent & Trademark Office, and has been Board Certified in Civil Trial Law since 1989 by the Texas Board of Legal Specialization.

“I have known and worked with the lawyers at AZA for many years and am excited to become formally associated with the firm,” says Mr. Warden. “AZA operates with an ‘unconventional wisdom,’ as we say at Rice University. They are brilliant and passionate lawyers working together with a special camaraderie to achieve the best results for their clients.”

Mr. Warden earned his law degree from University of Virginia after earning his bachelor’s and master’s degrees in engineering from Purdue University. He has been an adjunct professor at Rice University since 2006. He speaks French and some basic Mandarin, and is an instrument-rated pilot and a certified scuba diver. Before attending law school, Mr. Warden worked as an engineer and district production engineering supervisor for Exxon Corporation USA.

Mr. Warden’s business activities include serving as Vice President–Corporate Development for Excalibur Almaz, U.S.A. from 2009-2011. He also serves on the Board of Directors for Encore Bancshares Inc. and several other businesses and charities.
