Jeffrey Armstrong prepares and prosecutes patent applications at the U.S. Patent and Trademark Office (USPTO), litigates patent matters in federal district courts, and represents clients in ex parte reexaminations at the USPTO and inter partes reviews at the Patent Trial and Appeals Board (PTAB). 

Jeffrey uses his litigation experience to help clients obtain high value, litigation worthy patents that are drafted to withstand validity challenges in district court and post-grant proceedings at the USPTO while still covering desired technical features and functionality. He also relies on insight gained from patent prosecution to help clients develop successful legal and technical strategies during district court litigation and before the PTAB.

In addition to his litigation and prosecution practice, Jeffrey also authors legal opinions related to patent, trademark, trade secret, unfair competition, and copyright issues, and assists clients with licensing patents and patent portfolios.

Prior to his legal career, Jeffrey held a variety of engineering, technical management, and consulting positions. As an engineer at Nortel Networks, he worked with Synchronous Optical Networks (SONET), optical amplifiers, Dense Wave Division Multiplexing (DWDM) systems, Asynchronous Transfer Mode (ATM) switches, and Internet Protocol (IP) routers. After Nortel Networks, he worked at a venture-backed communications service provider where he designed, engineered, and implemented metropolitan and backbone voice and data networks. He also worked at Corvis Corporation as a product manager for optical transmission, optical amplification, and optical switching systems, and later as an engineering consultant to the U.S. Department of Defense in connection with communications technologies.
