John Marshall is a partner in the firm's Intellectual Property Practice Group. His practice concentrates on civil litigation involving patent, trademark and copyright infringement, representation of patent and trademark applicants before domestic and foreign government agencies, and advice and counseling to clients on intellectual property matters.
Civil Litigation. John began his law career in 1979 with an intellectual property firm where he became the primary associate in a series of actions involving patents on digital organs and keyboards. In 1981, he joined a general practice firm to concentrate on aircraft accident litigation, representing aircraft and equipment manufacturers and air carriers. He returned to intellectual property practice in 1988. John has tried cases in state and federal courts, and in the International Trade Commission, and has argued appeals in the Superior and Supreme Courts of Pennsylvania and in the Court of Appeals for the Federal Circuit. In one jury trial involving medical laser technology, he obtained a verdict for the plaintiff of willful infringement of three patents with an eventual settlement in excess of $8 million.
Patent Prosecution and Guidance to Clients. John became a registered patent attorney in 1979. He represents patent applicants in diverse technologies, provides advice to clients on matters of patent scope and validity, and assists clients in developing business strategies for exploiting their intellectual property assets.
In General. Before entering the practice of law, John was a U.S. Navy officer and aviator. He graduated from the Naval Academy in 1969, received his gold wings and a master's degree in aeronautical systems engineering in 1970, and flew maritime patrol aircraft in the Pacific and Southeast Asian regions until 1973, when he became an NROTC instructor at Holy Cross. John left active service in 1976 to attend law school, but remained in the reserve forces until he retired as captain in 1993.
