Legal Principles
In managing disclosure of confidential information, the court must balance the interests of the receiving and disclosing parties.
Warner-Lambert Co v Glaxo Laboratories Ltd [1975] RPC 354; Mitsubishi v One Plus (Shenzhen) [2020] EWCA Civ 1562
The court must consider the stage of proceedings and the structure/organisation of the receiving party when determining the appropriate level of confidentiality.
Mitsubishi v One Plus (Shenzhen) [2020] EWCA Civ 1562; Al-Rawi and others v Security Service [2011] UKSC 34
A staged approach to disclosure is appropriate, with restrictions potentially relaxed as the case progresses.

Outcomes
Appeal dismissed.
The Court of Appeal held that the judge's decision to impose the wide form undertaking was a proper exercise of his powers, given the early stage of proceedings, limited evidence from OnePlus regarding its organizational structure, and the potential for unfairness to both InterDigital and other counterparties if the narrower form was used. The court found that the risks of unfairness were matters of degree, not kind, and that a cautious approach at an early stage was justified.
