As a lead counsel, he has filed several patent re-examination petitions with the USPTO in two leading cases to invalidate Plaintiff’s patents based on undisclosed prior art.

Mr. Patel has been very successful in utilizing his prosecution experience to his advantage in developing strong litigation strategies to achieve the clients’ overall objectives. His attitude of managing intellectual property litigation with a focus on substantive rather than procedural issues has helped him develop strong client confidence and make patent litigation more economically manageable for the clients.
