The landscape of trademark opposition proceedings in Australia has undergone notable shifts over the past five years. From changes in filing volumes and success rates to evolving grounds of opposition and the impact of legislative reforms, the period from 2021 to 2025 has offered valuable insights for brand owners, legal practitioners, and anyone with a stake in Australia's intellectual property system. This trend analysis examines the key developments, drawing on publicly available data from IP Australia and decisions of the Australian Trade Marks Office.

Understanding the Opposition Framework

Before delving into the trends, it is worth revisiting the fundamentals. Under the *Trade Marks Act 1995* (Cth), any person may oppose the registration of a trade mark within two months of its publication in the *Australian Official Journal of Trade Marks*. Opposition proceedings are conducted before the Registrar of Trade Marks, with the possibility of appeal to the Federal Court of Australia.

The grounds for opposition are set out in Part 5 of the Act and include arguments that the mark is not inherently adapted to distinguish (section 41), that it is substantially identical or deceptively similar to an earlier mark (section 44), that the applicant does not intend to use the mark (section 59), that the application was made in bad faith (section 62A), and various other grounds relating to prior use, reputation, and public interest.

This framework has remained largely stable over the five-year period in question, but the way parties have engaged with it has changed considerably.

Filing Volumes: A Post-Pandemic Surge and Correction

The story of opposition filing volumes over the past five years is inseparable from the broader trade mark application trends that followed the COVID-19 pandemic.

In the 2020–2021 financial year, Australia experienced a significant surge in trade mark applications, driven in part by businesses pivoting to online commerce, new product launches in health and hygiene categories, and a general increase in brand awareness among small and medium enterprises. This topic is also covered in a detailed look at 20 most active trademark lawyers in. IP Australia reported receiving over 80,000 trade mark applications in that period — a substantial increase on pre-pandemic levels.

This application surge had a downstream effect on opposition proceedings. By 2022, opposition filing volumes had risen noticeably, as the sheer number of published applications created more opportunities for conflict between marks. The bottleneck was not merely numerical; many of the new applications came from applicants less familiar with the clearance process, increasing the likelihood of filing marks that were similar to existing registrations.

From 2023 onwards, a gradual correction took place. Application volumes began to stabilise, and with them, opposition filings moderated. However, they have not returned to pre-pandemic baselines. You can find related insights in the the federal court handles trademark disputes guide. The 2024–2025 period showed opposition volumes settling at a level approximately 10 to 15 per cent above the levels seen in 2019, suggesting a structural shift rather than a temporary spike.

Grounds of Opposition: Deceptive Similarity Remains Dominant

Throughout the five-year period, section 44 — the ground that a mark is substantially identical with, or deceptively similar to, an earlier trade mark — has consistently been the most frequently relied upon ground of opposition. This is unsurprising, given that brand conflict is the most common trigger for opposition action.

What has been notable, however, is the increasing sophistication of arguments around deceptive similarity. Opponents have placed greater emphasis on evidence of actual market confusion, consumer survey data, and detailed analysis of trade channels and consumer demographics. The Registrar's delegates and the Federal Court have, in turn, provided more nuanced guidance on how similarity is assessed in the context of digital marketplaces, where visual elements may carry different weight than in traditional retail settings.

Section 42(b) — which allows opposition on the basis that use of the mark would be contrary to law — has also seen increased attention, particularly in cases involving marks that may infringe Australian Consumer Law provisions or relate to regulated industries such as therapeutic goods and financial services.

The ground of bad faith under section 62A has attracted growing interest over the review period. A cluster of decisions in 2023 and 2024 explored the boundaries of what constitutes bad faith filing, particularly in the context of trade mark squatting and the registration of marks by agents or distributors without the consent of the brand owner. While bad faith remains a challenging ground to establish, the jurisprudence has become more defined, giving opponents clearer parameters for when such claims may succeed.

Success Rates and Outcomes

Analysing success rates in opposition proceedings requires some nuance. Not all oppositions proceed to a determination on the merits. A significant proportion are resolved through negotiation, resulting in withdrawal of either the opposition or the application, or amendments to the application (such as restricting the specification of goods or services) that satisfy the opponent's concerns.

Over the five-year period, the proportion of oppositions resolved prior to a hearing has remained consistently high — estimated at between 60 and 70 per cent. This reflects the practical reality that opposition proceedings serve as much as a negotiation mechanism as they do an adjudicative one. Many parties use the opposition process to bring the applicant to the table and reach a commercial resolution, such as a coexistence agreement or a consent arrangement.

Among those matters that do proceed to a hearing, opponents have historically faced an uphill battle. The onus of proof rests with the opponent, and the evidentiary requirements can be demanding, particularly for grounds such as reputation-based claims under section 60 or the well-known marks provision in section 6(1). Data from the past five years suggests that opponents succeed in roughly 40 to 50 per cent of contested hearings — a figure that has remained relatively stable, though with some year-to-year variation.

One emerging trend is the increasing use of evidence of online brand presence — including social media metrics, website traffic data, and online marketplace sales figures — to establish reputation and use. We explored this further in a detailed look at digital economy and trademark law: where. Hearing officers have shown a willingness to engage with this evidence, though they continue to emphasise the need for corroboration and reliability.

The Impact of IP Australia's Reforms

IP Australia has not stood still during this period. Several administrative and procedural reforms have influenced the trajectory of opposition proceedings.

The continued development of IP Australia's digital platforms has streamlined the filing and management of oppositions. The TM Headstart service, while primarily relevant at the application stage, has had an indirect impact on oppositions by encouraging applicants to address potential conflicts earlier in the process, before publication and the opportunity for third-party challenge.

The Registrar's practice of offering case management conferences in opposition proceedings has been refined over the period, with a greater emphasis on early identification of issues and encouragement of alternative dispute resolution. This aligns with the broader trend across Australian tribunals and courts towards active case management and proportionate resolution of disputes.

In 2024, IP Australia also updated several of its practice guidelines relating to evidence requirements in opposition proceedings, providing greater clarity on the types of evidence that hearing officers consider most probative. These updates were broadly welcomed by the profession and appear to have contributed to more focused and efficient hearings.

International Filers and Cross-Border Disputes

A notable trend over the five-year period has been the increasing involvement of international parties in Australian opposition proceedings. This reflects the globalisation of brand portfolios and the growing importance of the Australian market for international businesses.

Oppositions filed by overseas-based entities have risen as a proportion of total filings, driven in part by the expansion of international trade mark portfolios through the Madrid Protocol system. Under the Madrid system, international registrations designating Australia are examined and published in the same manner as direct national applications, and they are subject to the same opposition procedures.

Cross-border oppositions raise particular challenges around evidence gathering and the establishment of reputation in the Australian market. The Federal Court's decision in *Lodestar Anstalt v Campari America LLC* [2016] FCAFC 92 continues to provide important guidance on how foreign reputation is assessed, but the practical difficulties of proving Australian consumer awareness of an overseas brand remain significant.

Over the review period, there has been a growing body of decisions addressing how online and digital commerce affects the assessment of reputation and use in Australia. The borderless nature of the internet means that Australian consumers may be exposed to foreign brands through social media, streaming platforms, and international e-commerce sites, even where the brand has no physical presence in Australia. We explored this further in the 10 australian trademark lawyers to watch in-depth research. Hearing officers and the courts have grappled with the extent to which such exposure translates into the kind of reputation that supports an opposition.

Sector-Specific Trends

Certain industry sectors have featured prominently in opposition activity over the past five years.

The technology sector has seen a high volume of oppositions, reflecting the rapid pace of brand creation and the tendency for marks in this space to use common descriptive or suggestive elements. We explored this further in our 15 landmark australian in-depth research. Disputes involving software platforms, fintech services, and digital health products have been particularly common.

The food and beverage sector remains a perennial source of opposition activity, driven by the density of marks in classes 29, 30, and 33, and the high consumer recognition of brands in this space. Craft brewing, specialty coffee, and plant-based food brands have all contributed to a competitive filing environment.

The health and wellness sector experienced a marked increase in opposition filings during 2021 and 2022, coinciding with the pandemic-driven boom in health products. While this has moderated since, the sector remains active.

Looking Ahead: Themes for 2026 and Beyond

Several themes are likely to shape opposition proceedings in the coming years.

First, the role of artificial intelligence in trade mark searching and clearance may reduce the incidence of conflicting applications reaching the publication stage, potentially dampening opposition volumes over time. However, AI-driven brand creation tools could also increase the overall volume of applications, creating a countervailing effect.

Second, the ongoing evolution of consumer behaviour — particularly the shift to online purchasing and the influence of social media on brand perception — will continue to challenge traditional approaches to assessing deceptive similarity and consumer confusion.

Third, the Australian Government's periodic reviews of intellectual property legislation may yield reforms to the opposition process itself. While no major legislative changes are currently pending, there is ongoing discussion about streamlining procedures and reducing costs for small business participants.

Finally, the internationalisation of brand disputes shows no signs of abating. Australian practitioners will need to remain adept at managing cross-border evidence and navigating the intersection of domestic and international trade mark systems.

Key Takeaways for Brand Owners

For brand owners and their advisers, the trends of the past five years offer several practical lessons:

  • **Conduct thorough clearance searches before filing.** The high volume of applications and the density of the register mean that conflicts are increasingly common. Investing in comprehensive searching at the outset remains the most effective way to avoid opposition proceedings altogether.
  • **Engage early in the opposition process.** The data confirms that the majority of oppositions are resolved through negotiation rather than contested hearings. Early engagement with the opposing party can save significant time and costs.
  • **Build and preserve evidence of use and reputation.** Whether you are a potential opponent seeking to protect an existing mark or an applicant defending against an opposition, contemporaneous evidence of brand use, consumer recognition, and market presence is critical.
  • **Stay informed about procedural developments.** IP Australia's practice guidelines and procedural updates can have a material impact on how opposition proceedings are conducted. Keeping abreast of these changes ensures that your strategy is aligned with current expectations.
  • **Consider the international dimension.** For businesses operating across borders, a coordinated approach to trade mark protection — including monitoring and opposition strategies in key jurisdictions — is increasingly important.

The opposition process remains a vital mechanism for maintaining the integrity of the Australian Trade Marks Register and protecting the rights of brand owners. Understanding the trends that shape this process is essential for anyone involved in the strategic management of trade mark portfolios in Australia.
