David’s practice includes drafting and prosecuting patent applications, as well as assisting clients to enforce their patent rights once a patent is obtained.  He has diversified his area of practice so that he can assist his clients not only with patents in computer and software technology, but also in mechanical, materials science and medical-related technologies.

David’s professional engineering activities included modification and analysis of avionics and weapons computers on F/A-18 Hornet aircraft, which required SECRET government security clearance.  As a diagnostic Engineer, he coded software test programs to analyze analog and digital circuits.  His engineering experience enabled him to become a co-inventor on two patents, thereby maximizing value of new technology.

Ever since joining Morriss O’Bryant Compagni Cannon, P.C. as a founding shareholder, David has been able to devote significant time to protecting touch technology found in computers and mobile computing devices, friction stir welding technology that enables solid state welding of high melting temperature materials, and chemical analysis devices and technology for time-of-flight, ion mobility and ion trap mass spectrometry.
