The Court of Appeal of the Unified Patent Court issued a decision on February 27, 2026, concerning a request by Sibio Technology Limited for further exchanges of written pleadings. Sibio had previously filed a revocation action against Abbott Diabetes Care regarding European patent EP 3 831 283 B1, which was dismissed by the Central Division of Paris. Following an appeal, Sibio requested further written exchanges based on Abbott's auxiliary requests to uphold the patent. The judge-rapporteur rejected this request, noting that the auxiliary requests had already been addressed at the first instance and that Sibio had ample opportunity to respond. The proceedings will now move to the oral phase.
