Stefani Shanberg is a trial lawyer and head of Morrison & Foerster’s San Francisco litigation department. Stefani specializes in representing technology companies in intellectual property cases before the federal courts, the International Trade Commission, and arbitral tribunals.

Stefani’s clients have ranged from venture-backed startups to some of the world’s largest public companies. Stefani has obtained successful outcomes, often based on creative and novel issues of law, including winning cases at trial, on summary judgment, and on motions to dismiss, prevailing on advantageous claim constructions, winning motions to transfer and stay, and convincing the Ninth Circuit and Federal Circuit Courts of Appeal to affirm favorable lower-court rulings.

While her practice involves matters pending throughout the nation, Stefani has particular experience with investigations before the International Trade Commission. In 2016, she became the first West Coast president of the ITC Trial Lawyers Association (ITCTLA).

She is ranked by Chambers USA for International Trade: Intellectual Property (Section 337), something rare among California-based lawyers. Stefani has a unique perspective on the intersection between the needs of technology companies and litigation before the International Trade Commission. She has been commended for “see[ing] the big picture in ways that some other attorneys don’t,” being “very creative and show[ing] thorough leadership,” and “doing some very, very good work for big clients.” (Chambers USA 2021). The Daily Journal has named her among its Top 100 Intellectual Property Litigators in California from 2011 to 2021. She has also been named by the Daily Journal as among the Top Women Lawyers in California and by The Recorder as among the Women Leaders in Tech Law.
