On 2 July 2025, the European Patent Office’s (EPO) Enlarged Board of Appeal published its Decision on G 1/23. While the case originates from a question of novelty of a chemical compound, the final Decision has far-reaching consequences across all technical fields through the introduction of an almost US-style “on-sale bar”. In this first-look webinar, we will discuss:
- What does G 1/23 say?
- Similarities and differences with the US on-sale bar
- Implications for future EPO proceedings
