Heraeus Electronics GmbH & Co. KG v.Vibrantz GmbH
The Local Chamber Munich of the Unified Patent Court granted the claimant's application for re-establishment of rights (Wiedereinsetzung in den vorherigen Stand) under Rule 320 of the Rules of Procedure after the claimant missed the deadline for filing a cost determination application under Rule 151. The underlying decision of October 10, 2025 had split costs 60/40 between claimant and defendant and partially revoked European Patent 3 215 288. The court held that while lack of legal knowledge generally does not suffice as grounds for re-establishment, in this specific case the claimant's misjudgment of the legal situation could not be attributed to it despite legal representation. A dissenting opinion by Judge Brinkman argued the application should have been dismissed as inadmissible for lack of legal interest.

The Local Division Munich of the Unified Patent Court dismissed the infringement action, finding that the attacked embodiment did not include a pull loop or other graspable structure engageable by a hook as required by claim 1 of the patent. The defendant's conditional counterclaim for invalidity was not decided because it was dependent on a finding of infringement, and the defendant was ordered to bear the costs of the counterclaim.
