Justin John Cassell

He has written many patent applications in close cooperation with inventors and actively participates in the management of patent portfolios of companies. He helps clients evaluate inventions in the context of business objectives and applies his extensive prosecution experience to develop internal patent procurement strategies and procedures for clients. He routinely handles applications received from abroad in the United States, as well as filing applications in international patent offices directly and in accordance with the International Patent Cooperation Treaty. Mr. Cassell also counsels clients on patent validity and infringement. He has written numerous opinions to defend clients against charges of willful patent infringement, and has negotiated with opposing counsel about such patents. In addition, he regularly advises clients about infringement risks during the design process and has coordinated clearance studies requiring the evaluation of competitor patents. Prior to attending law school, Mr. Cassell worked as a design engineer with particular focus on industrial applications involving high temperature materials.
