Question juridique clé
Whether reinstatement was available after an expressly declared patent waiver
Solution extraite
Reinstatement was unavailable because the loss of rights resulted from an express waiver declaration, not from a missed deadline.
Motifs extraits
The court held that Art. 47 PatG on reinstatement did not directly apply; the request was nevertheless late because the one-year absolute deadline ran from the waiver declaration, not from discovery of the mistake.
