David A. Gosse helps clients protect their intellectual property rights through litigation, working on cases ranging from due diligence investigations through trial and post-trial motions. Dave has participated in six jury trials and has been part of several litigation teams on cases that settled in the weeks before trial. In addition, he helps clients procure and protect broad intellectual property protection at the U.S. Patent and Trademark Office, beginning with patent drafting and prosecution and extending to post-issuance reexamination and AIA proceedings as appropriate. Because his practice includes both the acquisition and the enforcement of patent rights, Dave is better able to understand and evaluate issues that arise in intellectual property protection.

Dave has worked extensively with clients to protect innovations including complex process control algorithms, gift card activation systems, industrial printing hardware and software, DRAM and Flash memory, RISC processors, and a variety of mechanical devices.

Trained as a mechanical engineer, Dave worked for an engineering and software development firm before he attended law school. He has practical, hands-on experience developing automation control solutions on a variety of platforms, including robots, machine vision systems, PCs, and programmable logic controllers, for many different industries.
