Questione giuridica chiave
Whether the sub-licensee had standing to sue patent infringement in its own name
Decisione estratta
The appellant lacked standing because it did not prove the contractual conditions allowing it to sue were met.
Motivazione estratta
The sub-license agreement gave the prior right to sue to the licensor; the sub-licensee could sue in its own name only after waiver or failure to sue within six months after notice, which was not shown.
