Second medical use patents remain one of the most commercially sensitive tools in the originator playbook. Yet they are among the most volatile of protection mechanisms when it comes to validity challenge and “skinny labelling” carve-out strategies.
This session will explore the latest case law updates and patentability challenges in the European, U.S., and Brazilian second medical use and skinny labelling spaces, covering new strategies for building and attacking these patents.
- What are the key implications of recent second medical use case law, including the landmark UPC Local Division ruling on Amgen v Sanofi (2024)?
- What is the current EPO stance on reasonable expectations of success for second medical use?
- How should companies approach plausibility and data requirements in Europe post G2-21?
- How has the UPC shaped strategy around second medical use claims?
- What does the U.S. Supreme Court decision in Hikma v Amarin reveal about the future of skinny labelling practice?
- How is the approach to second medical use patents evolving in Brazil, and what do INPI’s new examination guidelines mean for patentability and enforcement strategies?
- How do second medical use claims and skinny labelling practice interact with competition law?

Anna Wolters-Höhne
I am a highly experienced patent litigator with 20 years of expertise representing clients across all industry sectors in international patent disputes, with a particular focus on life sciences. I have been involved in several landmark patent cases and important innovator vs. innovator disputes.
My practice encompasses patent infringement and damages proceedings, nullity actions, compulsory licence cases before the German courts, opposition proceedings before the European Patent Office, and UPC advice. I am frequently involved in the coordination of complex, multi-jurisdictional cases through an extensive international network of counsel, patent attorneys, and technical, economic, and legal experts. With my significant litigation expertise, I have secured landmark preliminary injunction victories in the pharmaceutical and medical devices fields.
I also advise clients on the development of both offensive and defensive patent strategies for clients across all sectors. Clients value my responsiveness, commercial awareness, reliability, and commitment to achieving results. For me, success is a team effort: My "one team approach" includes not only my highly qualified team here in my office, but also each person who works on the case globally, whether it is a lawyer, patent attorney, or assistant from our Bird & Bird network or from a competitor. Most importantly, the client with their expertise is at the centre of I - we focus all our energy on winning the case together as one team.
