Pairing an ‘unparalleled combination of legal and business acumen,’ Morrison Foerster is the firm of choice for several global pharmaceutical companies facing patent challenges, whether looking to gain patent coverage for their novel drugs, or to enforce existing patents via the courts. The January 2023 merger with litigation boutique Durie Tangri saw experienced patent litigators Daralyn Durie, Adam Brausa, both in San Francisco, and Los Angeles-based Kira Davis join the practice, further enhancing its ability to take on major patent disputes concerning cancer treatments, biosimilars, small molecules and more. Practice head Michael Ward maintains a practice between San Francisco and Boston, overseeing patent portfolios for both drug developers and clients active in the agriculture field, whom he advises on protection strategies and licensing for their unique plants. In Palo Alto, Catherine Polizzi and Janet Xiao assist clients with the development of their patent portfolios, as it pertains to therapies for cancer, autoimmune diseases and gene therapy, among others. Based out of Washington DC, Stacy Amin handles FDA regulatory issues, including enforcement actions.
