Question juridique clé
Whether the appeal was admissible against the parts of the cantonal judgment deciding the patent nullity claim
Solution extraite
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.
Motifs extraits
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.
