1. Key takeaways

New arguments submitted late in the proceedings may be disregarded to uphold the front-loaded procedure (R. 9.2 RoP)

The court has the discretion to declare inadmissible new non-infringement arguments and evidence that a defendant introduces for the first time in its Rejoinder.

Defendants must present all grounds for non-infringement in their initial Statement of Defence (R. 24 RoP)

This principle is rooted in the RoP Preamble’s objectives of efficiency and fairness. Introducing new arguments in the final written submission contravenes the UPC’s front-loaded procedural framework.

Late filing is only justified if it responds to genuinely new arguments from the claimant

The court found the claimant’s interpretation in its Reply was consistent with its initial Statement of Claim, so there were no grounds to justify the defendant’s late submission.
