Factual and Procedural Background
The Defendant, Company A, appealed against a judgment and order of Judge Laddie dated 18th December 2000, which refused their application for an order that Company B should disclose certain documents pursuant to CPR Part 31.17. The dispute arises from a patent infringement action initiated by the Plaintiff, the patentee, and an exclusive licensee, concerning a patent claiming the use of a specific compound for inhibiting organ or tissue transplant rejection.
The Defendant denied infringement and challenged the patent's validity on grounds of lack of novelty, obviousness, and insufficiency. The issues of infringement and insufficiency were tried first, with the court ruling that the alleged infringement did not occur as the patent claims did not cover the derivative in question. Subsequently, the proceedings were reactivated to address novelty and obviousness, scheduled for trial in June.
The novelty challenge centers on a letter dated 14th October 1987 from the Plaintiff to a third party, which the Plaintiff admits writing but which the claimants argue was disclosed in confidence, potentially nullifying its use as prior art. The Defendant's obviousness case relies on the known immunosuppressive properties of related compounds and argues it was obvious to try the patented compound for transplant rejection inhibition.
The Defendant sought specific disclosure of documents held by Company B related to a collaboration with another entity, which allegedly contained material relevant to the obviousness and novelty issues. Company B refused disclosure, citing objections from a third party competitor. The Defendant then applied to the court for an order compelling disclosure. Company B did not oppose or consent to the application but left the decision to the court. The claimants opposed the application.
Legal Issues Presented
- Whether the court has jurisdiction under CPR 31.17 and section 34 of the Supreme Court Act 1981 to order Company B, a third party, to disclose documents relevant to the patent validity issues.
- Whether the documents sought are sufficiently relevant to the issues of novelty and obviousness to warrant disclosure.
- Whether the judge below correctly exercised discretion in refusing the order for disclosure.
- The scope and limits of disclosure orders when the class of documents includes some irrelevant material.
- Whether confidentiality concerns justify refusal of disclosure or restrictions on publication of evidence.
Arguments of the Parties
Defendant's Arguments
- The documents held by Company B are relevant to the obviousness and novelty issues, particularly concerning the knowledge and activities related to the patented compound and its analogues.
- The judge erred in concluding that some documents were irrelevant; relevance must be assessed contextually rather than document-by-document.
- The judge wrongly held that there was no jurisdiction to order disclosure of a class of documents containing some irrelevant items; the presence of irrelevant documents does not preclude disclosure of the relevant class.
- The judge improperly exercised discretion by failing to consider that Company B did not oppose disclosure, that the documents were already collected and inspected, and that disclosure would not impose an undue burden or be a fishing expedition.
- The documents are relevant to the question of confidentiality over the 1987 letter, as the collaboration context may indicate an obligation of confidence.
Claimants' Arguments
- The court lacks jurisdiction to order disclosure when the class of documents includes irrelevant materials.
- The documents include materials post-dating the relevant priority date, thus are irrelevant to the obviousness issue.
- Disclosure of broadly defined classes without specific identification imposes undue burden on the document holder.
- The judge correctly exercised discretion in refusing disclosure on grounds of relevance, burden, and necessity.

Court's Reasoning and Analysis
The court began by confirming the statutory jurisdiction under section 34 of the Supreme Court Act 1981, as amended, and CPR 31.17, which permits disclosure orders against non-parties where documents are relevant and necessary for fair disposal or cost saving. The court acknowledged that the documents sought relate to the collaboration between Company B and a third party and concern the patented compound and its analogues.
The court rejected the lower judge's conclusion that the presence of some irrelevant documents in the class barred disclosure, reasoning that relevance must be considered in context and that individual documents may vary in relevance but the class as a whole can be relevant. The court accepted that documents post-dating the patent priority date would be irrelevant and thus limited disclosure to documents created before 6th June 1991, two years after the priority date, aligning with standard disclosure practice in patent cases.
The court found that the documents could assist in assessing obviousness by showing what was known or thought by skilled persons at the relevant time, and could also shed light on the issue of confidentiality surrounding the 1987 letter, which is material to the novelty challenge.
Regarding discretion, the court held that since Company B did not oppose disclosure, the documents were already assembled, and the burden and costs were minimal and borne by the Defendant, the judge erred in refusing disclosure. The court emphasized that relevant evidence should not be excluded except in exceptional circumstances and that disclosure would serve the proper administration of justice.
Finally, the court considered confidentiality of certain exhibits and declined to order general confidentiality, consistent with open court principles, but was prepared to restrict confidentiality to two specific exhibits with no objection from the Defendant.
Holding and Implications
The appeal was ALLOWED. The court ordered that Company B disclose, within 21 days, all documents created before 6th June 1991 relating to the collaboration with the third party that were previously selected and boxed by Company B's personnel.
This decision ensures that relevant documentary evidence will be available for trial, facilitating a fair determination of the patent validity issues. The ruling clarifies that disclosure orders may be made for classes of documents even if some documents within that class are individually irrelevant, provided the class as a whole is relevant. It also underscores the court's discretion to order disclosure absent undue burden or opposition from the document holder. No new precedent was established beyond the application of existing principles to the facts.
