Recognized since 1991
Portland, Maine
Litigation - Intellectual Property
Litigation - Patent

Bob Stier concentrates on jury trials of cases involving scientific and technical subject matter, with a particular focus on patent, products liability, trade secret and other technology-related litigation. For 35 years he has successfully handled patent litigation nationwide at the trial and appellate levels for a wide variety of clients, especially those in the biotechnology and semiconductor industries. He recently assembled a group of more than 100 community banks and credit unions to present a joint defense against a company demanding license payments for the use of ATMs, which resulted in the dismissal of all claims against his clients and a covenant not to sue any of the group members.
Bob also frequently counsels clients on patent enforcement, infringement, validity and freedom to operate issues. Bob is also responsible for the firm's office in Sweden and typically spends about four weeks in Stockholm each year assisting Nordic clients with various IP issues in the U.S. His longstanding familiarity with the Swedish language and culture enable him to offer unique insights about resolving or avoiding disputes, a contribution much appreciated by Nordic clients, some of whom he has represented for over 25 years.
