Cory Bell, leader of Finnegan’s PTAB trials section, focuses on post-grant practice, patent prosecution management, client counseling, and litigation with an emphasis on computer and electronic technologies. He works with emerging and high-technology companies in various electrical sciences, including computer hardware and architecture, software, robotics, graphical user interfaces, communication networks, and content management systems.
Since working on the first ever post-grant review (PGR) of a covered business method (CBM) patent, Cory has represented patent owners and petitioners in over 200 post-grant review (PGR) and inter partes review (IPR) trials before the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO), and in related matters before the U.S. Court of Appeals for Federal Circuit. He co-authored the American Bar Association’s The Practitioner’s Guide to Trials Before the Patent Trial and Appeal Board, and teaches a course he created on post-grant practice at the Suffolk University Law School. Cory has been named by The Legal 500 U.S. as a Next Generation Partner for patent prosecution and recognized for his practice in the DC region by Intellectual Asset Management (IAM).
Cory helps clients with various budgets and desired outcomes (e.g., portfolio or company sale, licensing, defensive posturing) to develop patent prosecution strategies and maximize their return on investments in research and development. A former patent examiner at the U.S. Patent and Trademark Office (USPTO), he has more than ten years of patent experience and has evaluated thousands of patents and patent applications for licensing, monetization, or sale; assisted in prosecuting hundreds of patent applications; managed patent portfolios; developed invention harvesting programs; conducted patent landscaping and competitor analysis; and filed patent reexamination, PGR, and inter partes review (IPR) requests.
Cory’s litigation experience includes matters before U.S. district courts and the U.S. International Trade Commission (ITC). He has prepared non-infringement and invalidity contentions; managed fact discovery; worked with fact and expert witnesses to prepare declarations and expert reports; drafted claim construction and summary judgment briefs; and prepared presentations for technical tutorials and claim construction hearings.
Cory gained technical experience in communications, audio/video processing, and content and data management while working in the broadcast engineering department of NBA Entertainment. During his tenure as a patent examiner, he examined patent applications in the database and information management fields.
