Nokia Corporation v Interdigital Technology Corporation

A court may grant a negative declaration where the parties are within its jurisdiction and the claimant has a real commercial reason for seeking relief. Such declarations remain unusual and require caution, but their availability should be controlled through judicial discretion rather than artificial jurisdictional limits.

The statutory procedure for declarations of patent non-infringement does not exclude the court’s general declaratory jurisdiction where that procedure is unsuitable for the relief sought. A manufacturer’s interest in determining whether notified patents are essential to compliance with a technical standard can provide sufficient standing and a useful commercial purpose.

InterDigital appealed against Pumfrey J’s refusal, reported at [2006] EWHC 802 (PAT), to set aside Nokia’s claim or give summary judgment under CPR Part 24. Nokia sought declarations that about 30 patents notified by InterDigital to ETSI were not essential to compliance with the internationally agreed 3G mobile-telephone standard.

InterDigital accepted that the parties were properly before the court and that essentiality could be determined patent by patent. It argued that the court should decline declaratory relief because Nokia had no sufficient claim of right, section 71 of the Patents Act 1977 provided the appropriate remedy, and the declarations would serve no adequate purpose. The central issue was whether the claim had a realistic prospect of attracting the court’s discretionary declaratory jurisdiction.

1. Appeal dismissed. Jacob LJ gave the principal judgment. Carnwath LJ agreed and added observations on negative declarations; Waller LJ agreed with both judgments. The court held that InterDigital had not shown that Nokia lacked a realistic prospect of obtaining the declarations or that Pumfrey J had exercised his discretion on a wrong principle.
2. CPR 40.20 gives the court a discretionary power to make binding declarations where it has jurisdiction over the parties. A declaration normally requires a real reason and useful purpose. Nokia had a manifest commercial interest because, if the patents were essential to the 3G standard, its unlicensed activities would infringe them. Its interest in manufacturing standards-compliant telephones was sufficient standing. The fact that an English decision could determine rights only within the jurisdiction did not justify refusing to decide matters falling within that jurisdiction.
3. Section 71 of the Patents Act 1977 did not make the general jurisdiction inappropriate. That section would require particulars of a particular telephone and would permit relief only in relation to the specified act. Nokia instead sought determinations that the patents were not essential to compliance with the standard. The statutory procedure was therefore unsuitable for the relief claimed. Unilever plc v Procter & Gamble Company [2000] FSR 344 was distinguishable.
4. Carnwath LJ explained that, following Messier Dowty Ltd v Sabena SA [2001] 1 All ER 275, negative declarations should be controlled through the court’s discretion rather than artificial jurisdictional limits. They remain an unusual remedy and caution is required. Pumfrey J, with direct knowledge of the technical dispute, was entitled to decide that the claim should not be struck out summarily while factual questions about the trade understanding of ETSI declarations remained unresolved.
5. The prospect of numerous standards-related claims did not require the court to decline jurisdiction. Courts could reduce or divide cases involving excessive numbers of patents. Possible competition proceedings were also no reason to refuse jurisdiction. Jacob LJ provisionally regarded an unwithdrawn notification of essentiality as a continuing representation, but did not finally decide that issue or whether unjustified over-declaration could infringe competition law.

1. Court of Appeal (Civil Division): The appeal was dismissed by [2006] EWCA Civ 1618. The court upheld the refusal to set aside the proceedings or give summary judgment.
2. High Court, Chancery Division (Patents Court): Pumfrey J refused InterDigital’s application to set aside Nokia’s declaratory proceedings or obtain summary judgment: [2006] EWHC 802 (PAT).
