Timothy P. McAnulty


Timothy McAnulty practices all aspects of patent law, including district court litigations, post-grant proceedings, due diligence, strategic counseling, freedom-to-operate studies, opinion writing, and portfolio development. He represents clients across a wide range of technologies and works closely with them to develop strategies aligned with their business goals.

Mr. McAnulty focuses his practice on contentious patent proceedings before the U.S. Patent and Trademark Office (USPTO), including post-grant proceedings under the America Invents Act (AIA), reexaminations, and interferences. These proceedings often relate to and directly impact issues in parallel district court litigations, and Mr. McAnulty works closely with litigation counsel to coordinate strategies.

Throughout his career, Mr. McAnulty has conducted numerous due diligence investigations and freedom-to-operate studies. He often works with acquiring companies in evaluating the strength of a target portfolio and clearance of target products. He also works with target companies to prepare portfolios for acquisition and provides counseling through investment rounds, acquisition, and initial public offerings.

Mr. McAnulty has assisted many clients in developing patent portfolios with comprehensive strategies toward enforcement, competitive landscapes, licensing, and protecting commercial embodiments. He routinely counsels clients throughout all stages of product development and often works directly with technical teams through design changes. He has drafted and prosecuted hundreds of patent applications across various technologies. His technical experience includes medical devices, engine and exhaust-treatment technologies, hydraulics, business methods, control systems, green technologies, and chemical processes and equipment.
