Summary: Central Division Paris issued a costs decision in Seoul Viosys Co., Ltd. v. Photon Wave Co., Ltd. following a preliminary objection in a revocation action. The court held: (1) a separate cost decision under R. 150 RoP is admissible after a preliminary objection that closes the proceedings before that division (jurisdiction declined and case transferred to Paris Local Division); (2) value of the revocation action set at EUR 500,000; (3) value of the preliminary objection proceedings set at one-quarter of the revocation action value (EUR 125,000); (4) expert costs for an opinion on Art. 33(4) UPCA interpretation were not reimbursable. Photon Wave bears 80% of Seoul Viosys's recoverable costs for the preliminary objection.
