Factual and Procedural Background
This appeal arises from a dispute over the confidentiality of certain material disclosed by the patentee during revocation proceedings. The patentee sought to maintain confidentiality of specific documents even after the proceedings had ended. Initially, several documents were contested regarding confidentiality orders, but following discussions, the opponent abandoned its cross-appeal, and the patentee limited its appeal to one document. The judge had refused, of his own motion, to maintain confidentiality over that document despite the opponent not opposing the appeal. The court considered the matter of general importance and received assistance from counsel for both parties.
Legal Issues Presented
- Whether the confidentiality order under CPR 31.22(2) should be maintained for the document in question after the conclusion of the revocation proceedings.
- The appropriate legal test and principles for determining the continuation or lifting of confidentiality orders concerning disclosed documents post-trial.
- The interpretation and application of CPR 31.22(1)(a) regarding documents read to or referred to in a public hearing and their confidentiality status thereafter.
Arguments of the Parties
Appellant's Arguments
- The patentee argued that the advertising and promotional expenditure figures in page 2 of the schedule were highly commercially sensitive and not publicly available, warranting continued confidentiality.
- The patentee maintained that although commercial success was central to its case, the opponent did not challenge the promotional efforts argument at trial, thus the confidentiality of page 2 should be preserved.
- The patentee emphasized the legitimate commercial sensitivity of the information and the industry-wide recognition of such data as confidential.
Appellee's Arguments
- The opponent abandoned its cross-appeal and did not oppose the patentee's appeal regarding the confidentiality of the document in issue.
- The opponent had not sought the release of the confidentiality order during the trial for the document in question.

Court's Reasoning and Analysis
The court began by emphasizing the fundamental principle that justice must be administered in public, supported by both English jurisprudence and obligations under the European Convention on Human Rights. It acknowledged that confidentiality orders are exceptions to this principle and require strong justification.
The court analyzed CPR 31.22, focusing on the use and confidentiality of disclosed documents. It noted that confidentiality ceases when a document has been read or referred to in a public hearing, but this must be interpreted flexibly to reflect modern trial practices where documents may be pre-read or referred to in written evidence without being read aloud in court.
The court criticized the judge's imposition of a strict 'necessity' test derived from Scott v Scott, clarifying that this test relates to the need to hold a trial in public rather than to limited confidentiality within a trial. Instead, the court proposed a broader, balanced approach considering the document's role in the trial, the public interest in access, and the potential commercial harm from disclosure.
Applying these principles, the court found that page 2 of the schedule, containing advertising and promotional expenditure figures, played a very limited and peripheral role in the trial. Although it was referred to in passing, it was not central to the issues decided. The court accepted that the information is highly commercially sensitive and confidential within the relevant industry.
Balancing these factors, the court concluded that maintaining confidentiality for page 2 was justified under CPR 31.22(2), despite the document having been referred to in a public hearing. The court emphasized that this decision does not establish a general rule that such figures are always confidential, but reflects the particular circumstances of this case.
Holding and Implications
The court ALLOWED THE APPEAL IN PART by making an order under CPR 31.22(2) to maintain confidentiality in respect of page 2 of the patentee's Confidential Schedule of Commercial Success.
The direct effect of this decision is the preservation of confidentiality over the advertising and promotional expenditure figures disclosed during the revocation proceedings, protecting the patentee's commercially sensitive information from public disclosure. No broader precedent was established beyond the particular facts and context of this case.
