Mannheim Local Division procedural order granting CeraCon GmbH's application under R. 263 RoP to amend its counterclaim for revocation by introducing a new novelty attack based on prior art document EP 3 868 480 (WO 2021/131055, a PCT/JP2019/051559 family member) against Sunstar Engineering's patent EP 4 108 413. The court found the amendment admissible: CeraCon could not reasonably have discovered the document earlier (only found via a search commissioned in late March 2025), and the amendment does not unduly prejudice Sunstar. The oral hearing remains scheduled for 10 February 2026.
