Philip litigates patent infringement cases across a range of technologies, including the pharmaceutical, mechanical and electronic arts.

Phil has litigated cases on behalf of numerous pharmaceutical companies, manufacturers of magnetics, modules, circuit protection devices and interconnect products, and makers of communications and electronics parts and devices. He has also prepared Paragraph IV Certifications and Detailed Statements in connection with numerous ANDA filings. Phil handles USPTO-related matters, including the preparation and prosecution of patent applications, appeals and re-examinations. He has drafted patent license agreements, as well as patent non-infringement and invalidity opinion letters.

In addition to patent litigation and prosecution, Phil has experience in handling complex insurance coverage matters for life and health insurers and reinsurers, as well as bad faith and punitive damages claims. He has rendered coverage advice and opinions and represented insurers in first-and third-party coverage litigation in state and federal courts. His experience in insurance coverage issues has enabled clients to share, or pass off completely, exposure to risks that presented significant liability.
