I have 30 years’ experience as a lawyer and for approximately 25 years I have specialized in intellectual property disputes. I represent clients both in arbitration and before courts of law, with a special focus on patents, copyright and trade secrets.
Work highlights include: patent litigation relating to the active substances in, and formulations of, the pharmaceutical products Losec, Prozac and OxyContin; successfully representing a client in the first IP case passing the requirement of leave to appeal and certiorari to the Supreme Court since the restructuring of the Swedish IP court system in 2016; arbitration concerning scope and term of major multi-jurisdictional cross-licensing agreement; and defending the validity of a client’s infringed patent relating to large infrastructure projects. The latter resulted in one of the largest awards of damages in Swedish patent history. I have also represented a client in a dispute concerning electronic signatures with a value of SEK 7 billion.
