Industry Experience: AT&T / Philips / Lucent /Alcatel-Lucent 
Sought out as a “go-to” attorney by inventors, technical management, enforcement teams, colleagues, and company executives, including a Nobel Prize winner, Eugene has extensive in-house experience and works well with company technical and legal decision-makers. He develops and provides global protection for company intellectual property assets and uses those assets to generate significant revenue. He solves complex intellectual property problems by applying first principles. Eugene has extensive patent enforcement experience, having made claim chart and technical presentations to many of the largest electronics manufacturers, telecommunications companies, and computer related companies in the United States, Asia, and Europe, as well as to companies engaged in e-commerce. Those efforts resulted in the generation of millions of dollars in licensing revenue. Eugene is also a named inventor on 13 patents, so he understands intellectual property from the conception of an invention, through the filing and prosecuting of a patent application, asserting the patent against infringers, and preparing and concluding a licensing agreement. Before going into the intellectual property field, Eugene was the lead electrical engineer for the original telephone sets of the PARTNER® Advanced Communications System, a business communication system which sold over 300,000 units and is featured in movies and on TV.
