European patent law expert Derk Visser (partner) and Matthew Blaseby (senior associate) explore the consequences of decision G1/09 of the Enlarged Board of Appeal (EBoA) of the European Patent Office (EPO). Their commentary is published in the March issue of EPI Information.

G1/09 relates to the deadline for filing a divisional application after a decision of refusal has been issued. Whilst the EBoA gave a clear answer on this point, application of their reasoning to other procedural situations raises new questions for European patent procedure. For example, can a divisional application be filed in an unavailed period for requesting further processing? Can a divisional application be filed for a Euro-PCT application without paying any fees for the parent, when entering the European phase?

Using the EBoA’s rationale as basis, Derk and Matthew identify new and creative possibilities for filing divisional applications in Europe. Read the full text of the article on page 32 of EPI Information here.

Trade Secrets: Navigating geopolitical risks and IP theft in the semiconductor industry
04 November 2025
Semiconductors have always been a critical technology but have grown significantly in strategic importance in recent years. They have become the key building block in developing and existing markets, including quantum computing, edge computing, AI, IoT, automotive, cellular data technology, smartphones, robotics, and many more. The complex designs and innovations that power semiconductor manufacturing are invaluable both to the world’s economy and technological advancement. Consequently, the semiconductor industry has found itself at the centre of geopolitical tensions, especially between the United States and China. It has become a prime target for cyberattacks and intellectual-property (IP) theft. As such, companies operating in this area must be more vigilant in protecting their intellectual assets.
