TQ Delta, LLC v Zyxel Communications UK Ltd & Anor [2019] EWCA Civ 1277 (18 July 2019)

TQ Delta, LLC v Zyxel Communications UK Ltd & Anor [2019] EWCA Civ 1277 (18 July 2019)

Where an implementer waives its right to enforce a RAND undertaking and declines to seek a licence, there is no longer a justiciable dispute regarding the terms or entitlement to a RAND licence, and declaratory relief serves no useful purpose. The court should not continue proceedings or grant declarations in the absence of a real dispute or utility, especially where no foreign proceedings are extant and the relief would not affect the parties' rights in the jurisdiction.

Procedural Posture

Appeal / Court of Appeal Judgment on Appeal From High Court (patents Court) Regarding Strike Out Application and Declaratory Relief

Legal Issues

  1. 1 Whether the court should allow declaratory relief regarding RAND licence terms after the implementer waives reliance on the RAND undertaking
  2. 2 Whether a real commercial dispute remains after such waiver
  3. 3 Whether the continuation of the RAND trial is justified

Ratio Decidendi

Where an implementer waives its right to enforce a RAND undertaking and declines to seek a licence, there is no longer a justiciable dispute regarding the terms or entitlement to a RAND licence, and declaratory relief serves no useful purpose. The court should not continue proceedings or grant declarations in the absence of a real dispute or utility, especially where no foreign proceedings are extant and the relief would not affect the parties' rights in the jurisdiction.

Court Disposition

Appeal allowed

Orders

  • RAND trial struck out; claim for declaratory relief dismissed
