Troisièmement, à supposer même que les intervenants aient effectivement reconnu la « validit é » de l’enregistrement espagnol n 2 163 616, voire des autres droits antérieurs en cause, quod non, cette ° circonstance n’obligeait pas la division d’opposition et la chambre de recours à considérer que l’existence de ces droits était établie.
