Jeffrey (Jeff) B. McIntyre is a partner in the firm’s Litigation and Chemical departments. He is also active in the firm’s Pharmaceutical, Opinions and Counseling practice groups.

As lead litigation counsel, Mr. McIntyre represents plaintiffs and defendants through all phases of patent infringement actions in a variety of technologies well-suited for his degrees in chemistry and biology, such as cosmetics, steel, chemical manufacturing processes, polymer extrusions for automobile windshields, and pharmaceuticals.

Mr. McIntyre’s combined experience in litigation and patent prosecution not only provides him with unique insight into litigation positions such as, the successful Markman position concerning interpretation of “consisting essentially of” in L’Oréal v. Merck/Johnson & Johnson and the novel section 102(g) argument in Solvay v. Honeywell (see Representative Matters), but also allows him to translate lessons learned in the courtroom into prosecution techniques resulting in stronger patents. His dual experience allows him to take a patent from cradle to grave, working with inventors in drafting and prosecuting a patent and then enforcing it in the courts.

Mr. McIntyre is able to develop winning strategies to effect favorable resolution of actual or potential litigation in all areas of technology, with particular emphasis on chemical, pharmaceutical and biologics (biosimilars) technologies. He is a strategic counselor to global companies big and small.
