Nokia Corp v Interdigital Technology Corp

The grant of a negative declaration is a matter of discretion, rather than jurisdiction. Such relief requires a sufficiently defined and justiciable issue. It should serve a useful purpose and advance the aims of justice.

A standards-essential patent notification may constitute a formulated claim against potential users of the standard. The notification need not possess the specificity of a statement of case. An assertion that a patent may well be technically essential can therefore support proceedings for declaratory relief.

Applications to strike out or for summary judgment determine clear cases. Disputed facts are ordinarily assumed in the respondent’s favour, and summary judgment is appropriate when the outcome is known rather than merely predictable.

InterDigital had notified approximately 30 United Kingdom patents to ETSI as essential or potentially essential to standards governing the FDD form of 3G mobile telephony. Nokia sought declarations that equipment complying with those standards did not necessarily infringe the patents. It alleged that essentiality affected existing and prospective licensing terms.

InterDigital applied to set aside service for want of jurisdiction. Alternatively, it sought to strike out the claim under Part 3 of the Civil Procedure Rules 1998 or obtain summary judgment under Part 24. It argued that its notifications were not formulated claims of right, that section 71 of the Patents Act 1977 provided the appropriate statutory procedure, and that declaratory relief would serve no useful purpose.

The central issues were whether the patent notifications could support negative declaratory relief, whether the essentiality dispute was sufficiently defined and justiciable, and whether the claim was clearly unsustainable or abusive.

1. The application was dismissed. The court possessed jurisdiction to entertain the claim, the pleaded issues were sufficiently defined, and the proceedings were not an abuse of process.

2. Striking out and summary judgment are procedures for clear cases. Where facts are genuinely disputed, the respondent’s factual case must ordinarily be assumed to be true. The court should neither conduct a mini-trial on documents nor undertake a disproportionately extended investigation of contestable legal principles. Summary judgment is appropriate when the outcome is known, rather than merely predictable.

3. The grant of a negative declaration is governed by discretion rather than an absence or presence of jurisdiction. Its use should be scrutinised and refused where it serves no useful purpose. The court should nevertheless grant suitable relief where it advances the aims of justice. The underlying issue must be sufficiently clearly defined to be justiciable.

4. An assertion that a patent may well be technically essential can support a properly constituted claim for declaratory relief. A member’s notification to an international standards body that use of its invention is essential necessarily involves a formulated claim against potential users of the standard. “Formulated” does not require the degree of specificity expected in a statement of case. The present dispute was therefore materially different from a case in which a prospective claimant had not formulated any claim and was still investigating the facts.

5. The pleaded particulars of non-essentiality, the relevant standard and the patent material defined issues capable of judicial determination. Once the standard and patent claims were sufficiently settled, the technical question was whether compliant equipment necessarily used the invention.

6. The availability of section 71 of the Patents Act 1977 warranted caution but did not justify summary disposal. On InterDigital’s own argument, a copy of the relevant portions of the standard might not constitute an adequate description for that statutory procedure. It could therefore be incapable of answering whether the patents were essential to 3G compliance.

7. InterDigital’s discretionary objections—including lack of finality, proportionality, tactical purpose, licensing utility, floodgates and possible deterrence of notifications—were fact-sensitive and unsuitable for determination at this stage. They did not establish abuse of process. Nor was the theoretical possibility of implementation-specific infringement a proper basis for striking out a claim concerning patents notified as technically unavoidable.

In earlier related proceedings concerning 2G and 2.5G standards, the Court of Appeal had permitted Nokia’s claim for declarations of non-essentiality to proceed to trial. The present court found no material distinction between the relevant circumstances of those proceedings and the pleaded circumstances of this 3G claim.
