Questão jurídica principal
Whether the appeal against claims 1 and 4 remained admissible after expiry of the patent
Decisão extraída
No. The legal interest in injunctive relief and seizure of allegedly infringing goods had lapsed, so the appeal was moot to that extent.
Fundamentação extraída
Once the patent expired, the plaintiff no longer had a protectable interest in prohibition or confiscation measures.
