Carl’s current practice focuses primarily on patent prosecution, which he has been doing since 1996, as well as client counseling and opinion preparation. He handles a large portfolio of U.S., international, and foreign patent applications, including the preparation of patent applications, amendments, appeals, reexaminations, reissues, and other prosecution-related filings. He counsels clients on prosecution strategy and prepares patentability, freedom to operate, and validity opinions. Carl’s practice also includes advising clients regarding strategies for patent portfolio management and development, licensing, engineering design changes and design-around solutions, and other patent-related legal issues.

Carl has experience managing patent prosecution for both large and small high-technology companies, as well as managing a portfolio of electrical and biomedical engineering technologies for a large university. His litigation experience includes preparation of claim construction briefs and invalidity contentions, infringement analysis of accused products, and validity analysis of asserted patents. Other experience includes pre-litigation analysis of portfolios of pending patent applications to evaluate strength and developing prosecution strategies in view of potential future litigation.
