Centripetal Limited v.Palo Alto Networks, Inc.
The Court of Appeal of the Unified Patent Court rejected Centripetal Limited's appeal against the Mannheim Local Division's revocation of a Saisie Order that had granted Centripetal's application for preserving evidence and inspecting premises against Palo Alto Networks, Inc. in connection with European patent EP 3 821 580. The Court held that Centripetal's amended requests submitted on appeal, which sought to broaden the scope of the original Saisie Order, were inadmissible because they were filed for the first time on appeal without justification and seriously prejudiced Palo Alto's ability to defend itself.

The appeal was dismissed and Viosys was ordered to bear the costs of the appeal proceedings.

The Court of Appeal reversed the first instance decision, holding that claim 1 of the patent contained an inadmissible extension of subject matter because feature 5.2 (openings near the edge of the substrate) was not clearly and unambiguously disclosed in the original application as filed. Claims 1, 4, 5, 6, and 9 were declared invalid, the infringement claims were dismissed, and Viosys was ordered to bear the costs.

The Court declared the relevant claims invalid and rejected all infringement claims brought by Seoul Viosys.
