Factual and Procedural Background
The Plaintiff and the first Defendant had a commercial relationship as manufacturing jewellers, involving the company Acme Jewellery Limited ("Acme"). The Plaintiff was employed by Acme and held a minority shareholding (10%) gifted partially by the first Defendant. The dispute arose from the Plaintiff's claim that two patents registered in Acme's name were held on constructive trust for him, based on his alleged invention of a sleeper earring in 1988 and the nature of the relationship between the parties, described as a "quasi partnership".
Previously, a petition under section 459 of the Companies Act 1985 was brought by the Plaintiff alleging unfair prejudice in the conduct of Acme's affairs. The court ordered the purchase of the Plaintiff’s shares by the first Defendant at a valuation date of 31 July 1992. The current proceedings, commenced by writ in April 1998, involve claims that the patents are held on constructive trust for the Plaintiff, arising from alleged fiduciary breaches and the commercial relationship between the parties. The Plaintiff also seeks relief related to unjust enrichment and breaches of fiduciary duty.
Legal Issues Presented
- Whether the patents registered in Acme’s name are held on constructive trust for the Plaintiff.
- Whether the Plaintiff, as an employee and director, owns the invention under the Patents Act 1977, particularly section 39.
- Whether a proprietary remedy such as a constructive trust can be imposed for breaches of fiduciary duty and unjust enrichment related to the patents.
- Whether the Plaintiff’s claim is barred by the doctrine of res judicata or abuse of process, particularly under the principle in Henderson v Henderson.
Arguments of the Parties
Appellant's Arguments (Plaintiff)
- The Plaintiff contended that a constructive trust arises because the patents, derived from his invention, were held by Acme following a fiduciary relationship and quasi partnership with the first Defendant.
- He argued that the invention did not necessarily belong to Acme under section 39 of the Patents Act 1977, and that Acme held the patents on constructive or resulting trust for him.
- The Plaintiff asserted breaches of fiduciary duty by the first Defendant, including unconscionable conduct in lodging the patent applications in Acme’s name.
- He relied on the quasi partnership relationship as the basis for his beneficial interest and fiduciary rights.
Respondent's Arguments (First Defendant and Acme)
- The Defendants argued that under section 39 of the Patents Act 1977, the invention belonged to Acme as the employer, and no constructive trust arises in favour of the Plaintiff.
- They contended that the quasi partnership relationship did not affect the ownership of the invention or patents, which were properly vested in Acme.
- The Defendants maintained that any claim based on dismissal or breaches of fiduciary duty did not give rise to proprietary remedies such as a constructive trust affecting the patents.
- They further argued that the Plaintiff’s claim was barred under the doctrine of res judicata and abuse of process principles as established in Henderson v Henderson, since the issues could and should have been litigated in prior proceedings.

Court's Reasoning and Analysis
The court began by examining the ownership of the invention under section 39 of the Patents Act 1977, which generally vests ownership of inventions made by employees in the employer if certain conditions are met. The court noted that the relevant date for ownership was when the invention was made (November 1988), and that the Plaintiff’s claim to beneficial ownership would require showing that the invention did not fall within the statutory ownership provisions or that a constructive trust arose.
The court rejected the Plaintiff’s argument that the quasi partnership relationship altered the statutory ownership of the invention. It emphasized that the company structure and statutory framework govern patent ownership, and the "quasi partnership" was a shorthand for just and equitable considerations in company law, not a basis to override patent ownership rules.
The court found no basis for an institutional constructive trust because the invention was held by Acme as employer, and no unconscionable conduct or breach of fiduciary duty altered that ownership at the time the patents were applied for or granted. The alleged breaches related to the filing of the divisional patent application were not unconscionable, as entitlement proceedings exist to resolve such disputes.
The court considered remedial constructive trust claims arising from breaches of fiduciary duty and unjust enrichment but concluded there was no nexus between the dismissal or breaches and the proprietary remedy sought. Compensation claims could be pursued under section 40 of the Patents Act 1977, which remained available to the Plaintiff.
Finally, the court addressed whether the claim was barred by the doctrine of res judicata and abuse of process, referencing Henderson v Henderson and subsequent authorities. The court held that the constructive trust claim should have been raised and determined during the earlier s 459 petition proceedings, as it directly affected the valuation and share purchase order. The failure to litigate this claim earlier constituted an abuse of process, justifying striking out the claim and removing the first Defendant from the action.
Holding and Implications
The court granted the defendants’ application to strike out the Plaintiff’s claim that the patents are held on constructive trust for him.
The Plaintiff’s proprietary claim to the patents was dismissed on the basis that the statutory ownership provisions of the Patents Act 1977 apply, and the constructive trust claim was barred by the doctrine of res judicata and abuse of process. The court allowed the Plaintiff to pursue compensation claims under section 40 of the Patents Act 1977 but denied any proprietary remedy affecting the patents themselves.
The first Defendant was ordered to cease being a party to the action. No new legal precedent was established; the decision primarily clarifies the application of statutory patent ownership rules and the strict application of abuse of process principles to prevent piecemeal litigation of related claims.
