Proving Acquired Distinctiveness in Australia: How to Save a Descriptive Mark

When IP Australia raises a Section 41 objection on the ground that a trade mark lacks inherent distinctiveness, the applicant is not without recourse. The Trade Marks Act 1995 provides a mechanism to overcome the objection by demonstrating that the mark has, through use, acquired the capacity to distinguish the applicant’s goods or services in fact. This is the Australian equivalent of “acquired distinctiveness” or “secondary meaning,” and the evidentiary requirements are specific and demanding.

The Statutory Framework

The applicable provision depends on the degree of inherent adaptation and when the application was filed:

Marks with Some Inherent Adaptation (Section 41(3))

Where a mark has some but insufficient inherent adaptation to distinguish (Category (b) under the Cantarella framework), the Registrar may accept the application if the applicant can show, through evidence of use before the filing date, that the mark does in fact distinguish the applicant’s goods or services. The evidentiary threshold here is proportionate: the less inherently distinctive the mark, the more evidence of use is required.

Marks with No Inherent Adaptation (Section 41(6))

Where a mark has no inherent adaptation to distinguish (Category (c) — directly descriptive or generic), the burden is heavier. For applications filed on or after 15 April 2013 (post–Raising the Bar amendments), the applicant must demonstrate that, as at the filing date, the trade mark did in fact distinguish the designated goods or services as being those of the applicant because of the extent to which the applicant had used the mark before that date. This effectively requires proof that, by the filing date, consumers in Australia already associated the descriptive term with the applicant’s goods as a source identifier.

What Evidence Does IP Australia Require?

Evidence of acquired distinctiveness is typically submitted by way of a statutory declaration (or affidavit) with supporting exhibits. IP Australia’s guidance identifies the following categories of evidence as relevant:

1. Sales Data

Annual sales figures for goods or services sold under the mark in Australia, presented year by year. The data should show the volume and value of sales, ideally demonstrating sustained and growing commercial activity over the relevant period. Invoices, financial statements, and distribution records corroborate the sales figures.

2. Marketing and Advertising Expenditure

Annual advertising and promotional spend in the Australian market, broken down by year and by medium (television, online, print, outdoor, social media). Copies of actual advertisements, media schedules, and marketing campaign materials demonstrate how the mark was presented to Australian consumers. The emphasis is on investment directed specifically at the Australian market, not global advertising budgets that incidentally reach Australia.

3. Duration and Continuity of Use

Evidence of how long the mark has been in continuous use in Australia. Longer periods of uninterrupted use are more persuasive. Product packaging, catalogues, brochures, and point-of-sale materials bearing the mark and dated to the relevant period help establish continuity.

4. How the Mark Is Used

Evidence demonstrating that the mark is used as a trade mark — that is, as a source identifier rather than a descriptive term. Photographs of the mark on products, packaging, signage, and in advertising, showing it presented prominently as a brand name, are important. If the mark appears only in small print or in a descriptive context, it may not be perceived as a trade mark by consumers.

5. Geographic Reach

Evidence of use across Australia, not limited to a single city or state. Distribution records showing sales in multiple states and territories strengthen the case that the mark has acquired nationwide distinctiveness.

6. Market Recognition

Evidence that consumers, retailers, or industry participants recognise the mark as a brand. This may include consumer surveys (methodologically sound and conducted in Australia), media coverage, trade publication references, awards, and third-party acknowledgements that treat the mark as a source identifier rather than a descriptive term.

Timing: The Filing Date Threshold

For marks with no inherent adaptation (Section 41(6)), the acquired distinctiveness must be established as at the filing date. Evidence of use and recognition that postdates the filing date cannot be used to prove the mark was distinctive at the time the application was lodged. This makes it essential to collect and organise evidence of use before filing a descriptive mark.

For marks with some inherent adaptation (Section 41(3)), the evidentiary threshold is lower, and use “to some extent” before the filing date may suffice, depending on the degree of inherent distinctiveness.

Common Pitfalls

• Descriptive use defeats the claim: If your own use of the mark has been descriptive rather than as a trade mark, the evidence may actually work against you. A producer of “baked beans” who has used those words descriptively for years has not acquired trade mark distinctiveness, regardless of the volume of sales.
• Insufficient Australian evidence: Global sales and international advertising are not substitutes for Australian market evidence. IP Australia assesses acquired distinctiveness in the context of Australian consumers.
• Gaps in continuity: Interrupted use weakens the claim. Periods of inactivity suggest the mark may not have maintained its distinctive character over time.
• Post-filing evidence: For marks with no inherent adaptation, evidence generated after the filing date is inadmissible for establishing acquired distinctiveness at the relevant date.

Strategic Recommendations

• Build the evidence portfolio before filing: If you intend to register a descriptive mark in Australia, invest in commercial use first and organise your evidence before submitting the application.
• Use the mark as a trade mark: Ensure the mark is presented prominently as a brand identifier, not merely as a descriptive term, in all marketing and product presentation.
• File an inherently distinctive mark in parallel: Secure immediate protection with an inherently distinctive alternative while building evidence for the descriptive mark.
• Engage a professional survey if needed: A well-conducted consumer survey among Australian consumers can be persuasive evidence, particularly when other categories of evidence are modest.

Key Takeaway

Acquired distinctiveness is the statutory mechanism for registering descriptive marks in Australia, but it demands rigorous, Australia-specific evidence gathered before the filing date. Sales volume, advertising spend, duration of use, geographic reach, and evidence of consumer recognition are all relevant. The less inherently distinctive the mark, the more substantial the evidence must be. Planning and documentation are essential.
