With a degree in electrical engineering and substantial real-world experience in the high-tech industry, clients have entrusted him as lead technical counsel for numerous matters, in both litigation and transactions.

    His technical areas include all forms of electrical and electronic arts including computer architecture, storage systems and networks, server networks and architecture, microprocessors, memories, software and Internet applications, artificial intelligence, machine learning, neural networks, security, cryptography, telecommunications, wireless, interactive television and electronic program guides, satellite, business methods, semiconductor design and processing, semiconductor packaging, circuit design, electric and hybrid vehicles, autonomous vehicles, and medical devices.

    Prior to attending law school, Phil worked at a semiconductor company (now STMicroelectronics), in the areas of device engineering, process engineering, and automation.


    Phil has extensive experience in advising companies on the defense against and strategic assertion of patents. He has taken the lead on claim construction and developing arguments with respect to infringement, validity, and enforceability, overseeing and coordinating teams on the same. In a major case defending client STMicroelectronics, Phil spearheaded the efforts which led a court appointed expert to find that the asserted patents were invalid as being anticipated, obvious, and lacking adequate written description/enablement, and not infringed. He has represented clients in proceedings before District Courts (including the Northern District of California, the Central District of California, the District of Delaware, the Eastern District of Texas, the Western District of Texas, the District of Arizona, and the Western District of Wisconsin) and the International Trade Commission.

    Proceedings Before the U.S. Patent Office:

    Phil regularly advises companies on the strategic use of administrative proceedings before the U.S. Patent and Trademark Office (USPTO), including inter partes and covered business method review, often in conjunction with litigation. He was counsel in the first IPR case resulting in a successful final determination invalidating claims of the patent at issue. Phil has also prepared and prosecuted ex parte reexaminations before the USPTO.

    Patent Assessment and Portfolio Strategy:

    Phil regularly assists companies with making strategic decisions concerning patents, including the acquisition of individual patents or entire patent estates, in connection with or separate from merger and acquisition efforts. He has developed and implemented strategies for assessing patents and led teams of lawyers and experts in executing such strategies. He has performed and advised companies on due diligence investigations.


    Phil has experience in technology and IP transactions. He has negotiated, drafted, and counseled companies on agreements related to patents and other intellectual property in connection with public offerings, mergers and acquisitions, and resolution of litigation.
