Kernrechtsfrage
Whether the appeal was admissible against the parts of the cantonal judgment deciding the patent nullity claim
Extrahierter Entscheid
The appeal was inadmissible insofar as it targeted dispositive items 1 and 2, because the appellant sought only annulment and remittal, without a substantive request on how the claim should be decided.
Extrahierte Begründung
A civil law appeal is a reformative remedy. A mere annulment or remittal request is insufficient unless the Federal Supreme Court could not itself decide for lack of findings. That exception was not shown here.
