Mr. Berschadsky’s practice focuses on patent prosecution and litigation, freedom to operate analysis, U.S. and international strategic patent portfolio planning and management, as well as counseling clients on strategic partnerships and technology acquisitions. Having worked in the satellite communications industry on commercial spacecraft, the electronics industry on high-tech audio and electronics, and various Machine Learning applications of Artificial Intelligence qualifies Jonathan to work on all things "technologically complex." He can write about them for any audience: business folk, engineers, PTO examiners, judges and juries. When it comes to drafting patent applications, formulating arguments for high-stakes litigations, and rendering opinions on issues of patent infringement, validity and enforceability, Jonathan never leaves a stone unturned. He combines that with some serious agreement drafting and negotiating skills.

Jonathan is a regular CLE instructor for the Practicing Law Institute (PLI) and in-house counsel. Jonathan also moonlights as a mixed martial artist and on weekends goes mountain bike riding.
