Clement (Clem) Naples is a leading patent and trade secret trial lawyer whose practice focuses on litigating actions in federal and state courts, as well as in the International Trade Commission.

He has also led multiple worldwide litigation campaigns on behalf of plaintiffs and defendants.

Clem is regularly retained for “bet-the-company” litigations. His most recent trade secret matter, a multibillion-dollar dispute related to semiconductor manufacturing technology, was hailed as “one of the most complex trade secret battles in the semiconductor industry” (IAM, January 17, 2025, GlobalFoundries and IBM Call Truce On Semiconductor Trade Secret Battle).

Over the course of his career, Clem has litigated multiple cases through bench and jury trials and served as lead counsel in matters involving semiconductor manufacturing, cybersecurity, wireless communications, automotive technology, and video technologies.

He has particularly deep experience in cases involving semiconductor manufacturing and optical systems. Prior to becoming a trial attorney, Clem was a lead optical engineer at Silicon Valley Group Lithography Systems, now ASML. There, he focused on the optical performance of the Micrascan line of deep-UV step-and-scan lithography tools, optical metrology issues, and software for modeling the machines. On the legal side, this has translated into representing LCD manufacturers, U.S., and foreign-based based semiconductor manufacturers, and fabless semiconductor companies.

Clem regularly speaks on IP issues and is sought out for his advice on IP issues by business leaders. He was interviewed by Global Finance Magazine for their article, “Pricing And Protecting Patents.”

Clem joined the firm as a partner in 2025 after spending 18 years at another international law firm.
