Warner also has extensive experience in evaluating patents and providing opinions regarding clearance or freedom-to-operate, validity and invalidity, reverse engineering and design-around efforts, patentability, re-examinations and non-infringement.
Warner also counsels clients in transactional matters involving intellectual property, including license agreements, joint ventures, mergers and acquisitions, and other technology transfers, and he conducts due diligence searches in connection with such transactions. In addition, he handles intellectual property litigation matters in both federal and state court, and adversarial proceedings within the USPTO, including post-grant patent reviews, inter partes patent reviews, trademark oppositions and trademark cancellations.
Mr. Delaune received his undergraduate degree from Louisiana State University in mechanical engineering, and he was employed with Texas Instruments, Inc., in the Defense Systems and Electronics Group, where he designed infrared systems for use on military vehicles. He also participated in flight testing of those systems on both fixed wing aircraft and helicopters.
