Summary: Court of Appeal allowed OTEC's appeal and set aside the first-instance order granting provisional measures to STEROS. The CoA found the appeal successful and ordered that STEROS's application for provisional measures be rejected. STEROS was ordered to bear the costs of both the first-instance and appeal proceedings.

Summary: The Court of Appeal (Panel 1a: Grabinski, Gougé, Blok, Meewisse, Schmidt) partially granted STEROS GPA Innovative S.L.'s application for rectification (R. 353 RoP) of the Court of Appeal's order of 7 November 2025 which had set aside the Hamburg Local Division's provisional measures grant and rejected the application for provisional measures concerning EP 4 249 647. The court corrected a clerical mistake in margin 45 (Table 1 changed to Table 10), but rejected STEROS' further argument that margin 43 contained an 'obvious slip' since the proposed change would affect the substance of the reasoning.

Summary: Court of Appeal (judge-rapporteur Emmanuel Gougé) granted OTEC Präzisionsfinish GmbH's application for leave to file a further written pleading under R. 36 RoP in the appeal proceedings concerning a preliminary injunction granted by the Hamburg Local Division (16 June 2025) to STEROS GPA Innovative S.L. for infringement of EP 4 249 647. STEROS had introduced new experimental evidence in its Statement of Response; OTEC was granted two weeks to respond specifically to the experiments (Exhibits GRU 15–17) and related paragraphs of the Response. The Court found the exceptional circumstances required by R. 36 RoP were met given the new evidence.
