Clients ranging from the individual inventor to multinational companies, rely on Justin’s extensive experience to help them manage their patent portfolios of U.S. and foreign jurisdictions. He represents clients in a wide range of technologies including materials science, mechanical, electrical, and software technologies, with an emphasis on medical devices and procedures.

With a keen understanding of his clients’ business objectives, Justin evaluates inventions and develops patent procurement strategies to meet such objectives, both domestically and internationally.

Justin counsels and provides opinions regarding patent matters to address his clients’ needs and to fulfill their business objectives. These opinions advise on intellectual property issues ranging from patentability, due diligence, validity, and infringement. These opinions may lead to negotiation, licensing, acquisition, enforcement, or defense of patents.

Justin manages post-grant proceedings of his clients’ patents in both the U.S. and abroad and initiates post-grant proceedings of his clients to challenge competitor patents. Justin cooperates with litigation counsel on enforcement and defense of his clients’ intellectual property and advises his clients on such intricacies of U.S. patent litigation.
