In an important decision rendered on 24 April 2024, the Commercial Chamber of the Cour de cassation (i.e., French Supreme Court) ruled that the assignment of a patent is not enforceable against third parties if it is not registered, but that the regularization of this situation during the infringement proceedings allows covering all acts of…

While the patentability of further medical use claim defined by a dosage regimen used to be ruled out, the EPO’s Enlarged Board of Appeal has accepted them since decision G 2/08 in 2010. This patentability was also strongly debated before the French Courts, even after G 2/08, before being eventually recognized, although the interpretation of…

Readers are familiar with the story of the founding of the UPC, which “obliged” its founders to make it an ad hoc Court, not integrated into the European judicial system (with a reinforced cooperation agreement between the members of the UPC). The fragility of this system has provoked much criticism (e.g., our comments here). The…

Yes and no, it seems. Well, yes and then no, if recent French decisions are anything to go by. In short, Hesitations Blues reign. This attitude is all the more interesting given that the question, which arose more especially in the FINGOLIMOD case, has been raised before several European courts, all of which are opposed…

My British colleague has already commented brilliantly on the UK ruling in this case from the point of view of plausibility (see here). For my part, I’d like to comment the French ruling in the same case, which takes the opposite view to the UK decision. We shall see that the French position is particularly…

Here we are (at last), the UPC has opened its doors to claimants. Attorneys-at-Law before national Courts, like European patent attorneys, can now bear the new title of “UCP Representative” and thus exercise a new function of representative before UPC. This raises a number of questions for them. Like my colleagues, I have been consulted…

The Unified Patent Court has formally announced that, for the time being, competencies which were originally assigned to the London seat of the UPC central division, will be divided between Munich and Paris. Remarkably, there is no mention of Milan as third seat of the central division. Only two months ago, a spokesperson for the…

Many readers of this blog are familiar with the French saisie-contrefaçon, which consists of the seizure of allegedly infringing products and all related documents, but requires a writ of summons within one month of the saisie (e.g., here). Few of the same readers have probably heard of the protective seizure (“saisie conservatoire”), which allows similar…
