Court of Appeal dismissed Mara’s appeal and upheld the finding that EP155 was valid, rejecting obviousness over Bijl. EP801 remained invalid on the lower court’s reasoning.
The Patents Court granted expedition of RAND trial issues, directing the trial to the earliest possible time in Michaelmas term because of foreign injunction risk.
The strike out application was refused because there was no material benefit to be gained, the legal issue of aggregation is nuanced and should be determined at trial, and the discretion under CPR 3.4(2)(a) was exercised to allow both parties to argue their full cases. The split trial proposal was rejected because there was no clean split of issues, significant overlap and cannibalisation in product revenues, and the risks of increased costs, delay, and complexity outweighed any potential advantages.
