Cinpres Gas Injection Ltd v Melea Ltd

Factual and Procedural Background

This opinion concerns an appeal from a decision by Judge Mann regarding the ownership of European Patent (UK) No. 0,424,435. The dispute arose between two parties, hereinafter referred to as Plaintiff and Defendant, both of whom were found to have given perjured evidence in prior proceedings. The patent was registered in the name of Company A, controlled by Defendant, with Plaintiff named as the sole inventor. The invention, known as the "spillover" process, relates to plastics moulding technology developed initially while Plaintiff was engaged as a consultant for Company B, a competitor of Company A.

Initial proceedings under section 12 of the Patents Act 1977 were brought by Company B against Plaintiff and Defendant, concerning entitlement to the patent application. The Patent Office Hearing Officer initially ruled in favor of Defendant and Plaintiff, finding independent invention. This decision was reversed on appeal by a judge but reinstated by this Court. The patent was eventually granted to Company A with Plaintiff named as sole inventor.

Subsequently, Plaintiff admitted to perjury in the first proceedings. Company B then initiated entitlement proceedings under section 37 of the Patents Act 1977. The Patent Office declined jurisdiction under s.37(8), transferring the matter to the court. The proceedings before Judge Mann concluded that although Plaintiff had perjured himself, Defendant was unaware of this perjury at the time. The doctrine of res judicata was applied to bar Company B's claim.

The appeal before this Court raised multiple complex legal questions, including issues of inventorship, contractual entitlement, res judicata, and the applicability of equitable doctrines.

Legal Issues Presented

1. Was Plaintiff the actual devisor (inventor) of the invention while working as a consultant for Company B?
2. Did Company B acquire the right to apply for the patent through contractual arrangements with Plaintiff?
3. Is Judge Mann's finding that Defendant did not know of Plaintiff's perjury at the time of the first proceedings supportable?
4. Should Plaintiff's perjured evidence be attributed to Defendant on the basis that Plaintiff was more than a mere witness and part of Defendant's litigation team?
5. Does issue estoppel apply rather than cause of action estoppel, thereby affecting the operation of res judicata?
6. Does the former equitable jurisdiction to set aside a court decision by a Bill of Review still exist and apply here?
7. Does Plaintiff's status as a party to the first proceedings mean Defendant should be similarly bound by res judicata?
8. Should the false evidence of Plaintiff be treated as evidence of Company A, given the connection to ownership of the patent?
9. Between the rival claimants, would equity favor the first, such that Defendant would be obliged to relinquish the patent upon learning the truth?

Arguments of the Parties

Appellant's Arguments (Company B)

• Plaintiff was the sole inventor and acquired knowledge of the invention while consulting for Company B, entitling Company B to the patent.
• The contractual agreement between Plaintiff and Company B conferred on Company B the right to apply for the patent as successor in title.
• Defendant knew or ought to have known of Plaintiff's perjury, invalidating the prior judgment and defeating res judicata.
• Plaintiff was a vital member of Defendant's litigation team, so his perjured evidence should be attributed to Defendant.
• The case involves issue estoppel rather than cause of action estoppel, allowing re-litigation on new evidence.
• The Bill of Review equitable jurisdiction should allow setting aside the prior judgment due to fresh evidence and fraud.
• Defendant should be bound by res judicata as Plaintiff was a party to the first proceedings.
• The false evidence should be treated as that of Company A, which continues to rely on it.
• Equity would require Defendant to relinquish the patent upon learning the truth.

Respondent's Arguments (Company A)

• Plaintiff was not the actual devisor of the invention or did not assign rights to Company B at the relevant time.
• The contractual arrangements did not confer on Company B the right to apply for the patent for the invention in dispute.
• Defendant did not know of Plaintiff's perjury at the time and thus cannot be held responsible for it.
• Plaintiff was merely a witness, not part of Defendant's litigation team, so his perjury should not be attributed to Defendant.
• The doctrine of res judicata applies fully, barring re-litigation of the patent entitlement.
• The Bill of Review jurisdiction does not exist or is inapplicable.
• Company A, as registered proprietor, is entitled to rely on the patent registration against third parties.

Court's Reasoning and Analysis

The Court began by affirming Judge Mann's finding that Plaintiff was the sole inventor, having acquired knowledge and developed the inventive concept while consulting for Company B. The Court emphasized the importance of identifying the "actual deviser" as per section 7 of the Patents Act 1949 and the House of Lords decision in Yeda.

Next, the Court addressed whether Company B acquired the right to apply for the patent through contractual arrangements. Despite the contractual agreement being entered after Plaintiff's consultancy ended, the Court found that the final agreement conferred on Company B the rights to the invention as "Cinpres Technology," making Company B a successor in title under section 7(2)(c). The Court rejected the argument that the point was raised too late and found the commercial context supported this interpretation.

Regarding whether Defendant knew of Plaintiff's perjury during the initial proceedings, the Court applied the established appellate standard for reviewing factual findings, emphasizing the deference owed to trial judges on credibility. The Court concluded that the evidence did not demonstrate that Defendant had knowledge of the perjury at that time, upholding Judge Mann's finding.

However, the Court diverged from the prior ruling by holding that Plaintiff was not a mere witness but a party to the initial litigation, acting as Defendant's "comrade in arms." Therefore, Plaintiff's perjured evidence should be attributed to Defendant, satisfying the "fraud of the party" exception to res judicata established in Odyssey.

The Court considered the "litigation team" argument but declined to allow it as it was not pleaded or raised below and could involve additional evidence.

On the issue of estoppel, the Court analyzed cause of action estoppel and issue estoppel, concluding that the present case involves the same cause of action as the prior proceedings and that the doctrine of res judicata applies fully.

The Court undertook an extensive review of the historical and modern law concerning the bill of review jurisdiction. It acknowledged the equitable jurisdiction to set aside judgments for fraud or fresh evidence but concluded that this jurisdiction does not provide a broader exception to res judicata than that established in Odyssey. The Court rejected the argument that the bill of review jurisdiction should apply to this case.

Finally, the Court examined the legal effect of Defendant and Company A continuing to rely on Plaintiff's false story to assert ownership of the patent. It held that Company A's claim to title depends entirely on Plaintiff's fraudulent representation and that Company A thereby adopts and continues to rely on that fraud. This ongoing representation constitutes "fraud of the party," justifying setting aside the prior judgment.

In summary, the Court allowed the appeal on the basis that Plaintiff's perjury should be attributed to Defendant, thereby unraveling the prior judgment and permitting Company B's claim to proceed.

Holding and Implications

The Court ALLOWED THE APPEAL.

The direct effect of this decision is to set aside the prior judgment that barred Company B's claim to the patent on grounds of res judicata. By attributing Plaintiff's perjury to Defendant and Company A, the Court removed the legal bar preventing re-litigation of entitlement to the patent. This allows Company B to pursue its claim to ownership based on Plaintiff's inventorship and contractual rights.

The Court did not establish any new precedent beyond clarifying the application of the "fraud of the party" exception to res judicata in the context of patent entitlement disputes involving perjured evidence by a party closely connected to the defendant. No broader implications or changes to the law of patent ownership or procedure were indicated.
