Background

Acer and ASUS were involved in Patents Court proceedings against Nokia concerning RAND patent-licensing terms. After the Court of Appeal stayed those proceedings so the parties could arbitrate their dispute, Acer and ASUS applied to lift the stay temporarily and amend the existing confidentiality regime. They sought permission for confidential materials produced in the court proceedings to be disclosed to and used by legal representatives and the tribunal in the forthcoming ICC arbitration.

Nokia did not oppose disclosure in principle but argued that the parties should wait for the arbitral tribunal, once constituted, to issue its own protective and document-production orders. Acer and ASUS responded that constitution of the tribunal could take months and that ASUS’s chosen arbitration counsel would otherwise have to prepare its response to Nokia’s request for arbitration without access to key pleadings and other restricted materials.

The Court’s Holding

Mr Justice Mellor granted the application and directed the parties to prepare an order implementing his decisions. He accepted Acer and ASUS’s prejudice analysis, finding that postponing access would impede their preparation for the arbitration, while Nokia’s principal burden was notifying counterparties. The court considered amendment of the confidentiality regime an obviously necessary step that facilitated the Court of Appeal’s order and the adjustable licences entered into by the parties.

The court permitted confidential materials generally—not only documents associated with the final RAND-licence issues—to be disclosed and used in the arbitration. A narrower approach would create a two-tier system requiring the High Court to decide whether particular documents concerned final RAND terms while the tribunal separately decided admissibility. The tribunal would instead be able to exclude irrelevant material and resolve disputes over confidentiality designations, redactions, and related issues.

The judge rejected requirements for advance third-party notice because the existing confidentiality protections were not being removed, and declined to require documents to be relabelled to refer expressly to the amended order. Existing labels would apply to the confidentiality order as amended, and recipients would receive the new order.

Key Takeaways

  • A stay of court proceedings may be lifted for the limited purpose of adapting an existing confidentiality regime to support an agreed arbitration.
  • The court allowed confidential materials to be used before the arbitral tribunal was constituted, avoiding a potentially lengthy period in which arbitration counsel lacked access to key documents.
  • The arbitral tribunal may manage confidentiality disputes and evidentiary admissibility without requiring the parties to return to the High Court.

Why It Matters

The decision shows that English courts may modify court-based confidentiality protections to ensure that a related arbitration can proceed effectively, particularly where delay would prevent chosen counsel from reviewing material central to the dispute. The court balanced the continued protection of confidential information against the need for prompt and fair preparation.

For parties moving patent-licensing disputes from litigation to arbitration, the judgment also highlights the value of aligning confidentiality arrangements early. Waiting for a tribunal-generated protective order may be inappropriate where the tribunal has not yet been constituted and existing court materials are needed for the arbitration’s opening stages.
