Quach v Registrar of Trade Marks

Quach v Registrar of Trade Marks [2025] FCA 1544 is a Federal Court procedure decision about joinder in a trade mark appeal. It is not a ruling on whether the mark itself should ultimately be registered. That distinction matters. The Court was dealing with who needed to be in the case, not who should win the branding dispute.

The decision arose after a delegate of the Registrar of Trade Marks rejected an opposition to a trade mark application for “Byron Bay Beachfront Apartments” with a stylised turtle logo. When an appeal was then attempted, the Court had to decide whether the Proprietors of Strata Plan 48462 should be added as a respondent because they were said to be the party that held the application and benefited from the Registrar’s decision.

For business owners, the practical message is that trade mark litigation is not only about distinctiveness, reputation or confusion. It is also about getting the parties right. If ownership has changed, or if the brand sits within a trust, property structure or related entity arrangement, the Court may need the actual rights-holder before it can properly deal with the dispute.

The published reasons set out a fairly specific commercial sequence. Medcraft Pty Ltd filed the trade mark application on 21 December 2023. The mark covered the words “Byron Bay Beachfront Apartments” and a stylised turtle logo. QE Family Pty Ltd, as trustee for the Qe Tai Sing Family Trust, then opposed registration on 27 May 2024.

The reasons say that on or about 5 June 2024 the application was purportedly assigned to the Proprietors of Strata Plan 48462. The Proprietors later filed a Notice of Intention to Defend on 31 July 2024. That means the application appears to have changed hands during the opposition process, which is exactly the kind of factual development that can complicate later Court proceedings.

On 5 August 2025, a delegate of the Registrar decided that QE Family had failed to establish any of its opposition grounds. As a result, the application could proceed to registration. That was the operative result in favour of the application side.

The matter then moved to the Federal Court. On 1 September 2025, Dr Michael Van Thanh Quach filed an application for an extension of time to appeal. The Court immediately identified a problem. The application had been filed by Dr Quach personally, even though the reasons say the relevant “opponent” was QE Family. The Registrar was also named as respondent, even though the party with the real commercial interest in preserving the decision was the Proprietors.

After case management hearings in October 2025, the Court required any interested party to file a joinder application. The Proprietors did so on 5 November 2025. That application led to this judgment.

The issue before Derrington J was narrow but important. The Court was not deciding whether the trade mark should be registered, whether the opposition grounds had merit, or whether the attempted appeal was valid. The immediate question was whether the Proprietors of Strata Plan 48462 should be joined as a respondent to the proceeding.

The reasons refer to rule 9.05 of the Federal Court Rules 2011 (Cth), which allows the Court to join a person if that person ought to have been joined or if joinder is necessary so each issue in dispute can be heard and finally determined. The judgment also discusses rules 1.32 and 1.35 because the joinder application had been initiated by a non-party. The Court accepted that a non-party could seek joinder through the Court’s broader procedural powers, or in any event because the application was supported by the Registrar, who was already a party.

So the real question was practical: could this appeal sensibly continue without the entity that was said to hold the trade mark application and that would lose the benefit of the Registrar’s decision if the appeal succeeded? The Court’s answer was no.

Derrington J granted the joinder application and ordered that the Proprietors of Strata Plan 48462 be joined as a respondent. The reasoning was direct. The Court said it was “right and proper” that the Proprietors be made a party to the appeal.

The key point was that the Proprietors were, as a matter of fact, the parties in whose favour the Registrar’s decision had been made. At that level, they had successfully obtained an outcome that allowed the application to proceed to registration. If the appeal succeeded, they would lose the benefit of that result.

The Court acknowledged that an appeal under section 56 of the Trade Marks Act is by way of rehearing de novo, meaning the issues are ventilated afresh. Even so, that did not reduce the Proprietors’ interest. The Court considered them directly affected by the opposition and by the attempted appeal. The reasons also note that they were notionally at least, if not actually, the trade mark applicants, and that the mark was said to apply to their premises, described as a beachfront unit development at Byron Bay.

On that basis, the Court held both that they ought to have been joined and that their joinder was necessary because the issues in dispute could not be finally determined without them. The order for joinder was therefore made.

This is the most important clarification for business readers. The Court did not decide the substantive trade mark dispute. It did not rule on whether “Byron Bay Beachfront Apartments” with the turtle logo should ultimately be registered. It also did not decide whether the opposition grounds had merit. Those questions were outside the scope of this interlocutory judgment.

The Court also did not resolve the procedural difficulties it had identified with the attempted appeal. The reasons specifically note that one difficulty was that the application for an extension of time had been filed by Dr Quach in his personal capacity, even though the relevant opponent was QE Family. The Court said that was a matter for another day.

That means this case should not be read as authority that the appeal itself was properly constituted, timely, or likely to succeed. It should be read as authority for a narrower proposition: where a party stands to lose the benefit of a Registrar decision in a trade mark appeal, that party may need to be joined so the issues can be finally determined.

The reasons also record that, once the Proprietors were joined, the Registrar would file a submitting appearance and otherwise not take a further active part in the proceeding. That is a useful practical point. In many appeals of this kind, the real contest is between the private parties whose commercial rights are affected, not between a business and the regulator.

If your business owns or uses a brand, this case is a reminder that trade mark disputes are also records and structure disputes. The Court needed to know who actually held the application and who would be affected by the appeal. If your business has assigned a trade mark application, restructured ownership, or split brand use across different entities, those details can become central in litigation.

This is especially relevant for businesses in accommodation, tourism, hospitality and property-related operations, where a brand may be linked to a location, development or building and may be used by one entity while owned by another. The reasons here refer to a beachfront unit development at Byron Bay. In that kind of setting, the relevant legal actors might include an operating company, a trustee, a property owner, a strata body or another related entity. If the wrong one is named in Court documents, the case can become bogged down before the merits are even reached.

The decision also shows that a win before the Registrar is not always the end of the matter. If the other side seeks to appeal, the beneficiary of that decision may need to become an active litigant in the Federal Court. That means keeping assignment documents, notices of intention to oppose or defend, and ownership records in good order from the start.

Finally, this case is a warning against assuming that the person most involved commercially is automatically the person entitled to bring the appeal. The Court expressly noted the problem that Dr Quach filed the extension application personally rather than the company identified as the opponent. For business owners, the lesson is simple: the legally correct party matters.

For a business preparing for a trade mark opposition or appeal, this case points to a practical file review. Start with the trade mark application itself and any assignment documents. If ownership changed, make sure the transfer is properly documented and consistent with the position being taken in the proceeding.

Then review the opposition documents. Who filed the Notice of Intention to Oppose? Was it the same legal entity that now wants to appeal? If a trust is involved, check the trustee details carefully. If a person is closely connected to the business, do not assume that person can file in their own name if the legal rights sit with a company or trustee.

Next, look at the Court documents. This judgment shows that naming the Registrar as respondent may not be enough where another party is the true beneficiary of the decision under challenge. The Court may require that party to be joined so the dispute can be properly determined.

Finally, think about the commercial setting. The reasons mention that the mark was said to apply to the Proprietors’ premises. If your branding is tied to a venue, development, building or managed property, be ready to explain the relationship between the mark, the premises and the entity claiming the rights.

The judgment was delivered on 3 December 2025 and the reasons were published on 8 December 2025. It is an interlocutory decision in the Federal Court of Australia. The order made was limited to joinder. The reasons expressly state that some difficulties still stood in the way of a hearing of the appeal, including the fact that the extension application had been filed by Dr Quach personally. The judgment does not resolve those issues and does not record the later outcome of the appeal.

Accordingly, this case note should be used as a procedural explainer about joinder in trade mark appeals, not as a complete account of the underlying brand dispute or the final appeal result.
