Australian trade mark law has taken a notable turn in its treatment of profanity.
In a recent decision of a delegate of the Registrar of Trade Marks — Renthat Pty Ltd Trade Mark Application (UNFVCK YOURSELF) — IP Australia held that the mark UNFVCK YOURSELF is not “scandalous” within the meaning of s 42(a) of the Trade Marks Act 1995 (Cth) when used in relation to adult-focused goods and services.
The decision marks a significant development in the interpretation of the long-standing prohibition on scandalous trade marks.
The mark
The applicant, Renthat Pty Ltd, applied to register a figurative mark incorporating the phrase UNFVCK YOURSELF for goods and services including:
-
vitamin and nutritional supplements
-
clothing and merchandise
-
retail and marketing services
An examiner objected under s 42(a), arguing the mark effectively reproduced the word “unfuck yourself”, which the examiner thought would likely offend a section of the community.
Despite three rounds of submissions, the objection was maintained and the matter proceeded to an ex parte hearing under s 33.
Counsel Melissa McGrath, instructed by Scott Coulthart of Mills Oakley, appeared for the applicant.
The legal issue: what counts as “scandalous”?
Section 42(a) requires rejection of trade marks that contain “scandalous matter”. However, the Act does not define “scandalous”.
The delegate confirmed the accepted test, which is that the mark in question must cause “a significant degree of disgrace, shock or outrage” to an appreciable section of the public — something more than mere offence or bad taste.
That threshold has always left room for debate.
The key question was therefore whether the word “fuck” still meets that threshold in modern Australian society.
Language evolves — and so does trade mark law
The applicant relied heavily on linguistic evidence from Associate Professor Nick Wilson, who explained that:
-
the word “fuck” has become commonplace in everyday Australian speech
-
contemporary audiences are far less shocked by its use than in previous decades
-
swear words used non-abusively often function as expressions of solidarity or emphasis
Research cited in the decision (and in Associate Professor Wilson’s report) suggested the word rated only 1.7 out of 7 in perceived offensiveness among Australian university students — well below racial or gender slurs.
The delegate agreed that Australian language norms have shifted. She concluded that most adult consumers would not experience a significant degree of shock or outrage when encountering the word in a commercial context.
But children changed the analysis
The examiner’s objection did not fail entirely.
The delegate identified one problem: the specification included “vitamins for children”, and parents of young children might reasonably object to encountering coarse language when buying products for children.
That context could make the mark “shocking” in that particular commercial setting.
The solution was elegant. The delegate offered the applicant the opportunity to amend the specification to adult-only goods and services, including:
-
vitamin supplements for adults
-
clothing for adults
-
retail services targeting adults
Once those amendments were made, the objection under s 42(a) fell away, and the mark was accepted for registration.
Why the decision matters
This decision is significant for several reasons.
1. It raises the practical threshold for “scandalous”
The delegate effectively confirmed that coarse language alone is not enough.
A mark must cause genuine shock or outrage, not merely offend sensibilities.
2. Context matters more than ever
The decision emphasises the importance of context, including:
-
the nature of the goods and services
-
the target market
-
where consumers encounter the mark
The same word may be acceptable in one context and unacceptable in another.
3. Specifications can solve morality objections
The decision shows that specification amendments can resolve objections.
Limiting goods and services to adult audiences may allow marks containing strong language to proceed.
4. Examiner practice may need to change
Historically, IP Australia examiners have been cautious with profanity-based marks.
This decision signals that automatic objections based solely on swear words may no longer be sustainable.
Applicants may now feel more confident pushing such objections to hearing.
The broader trend
The decision also reflects a broader international trend.
In recent years:
-
the US Supreme Court struck down prohibitions on “immoral” and “scandalous” marks
-
courts have increasingly recognised that language evolves
Australian law still retains the statutory prohibition, but Renthat shows that its application is becoming significantly narrower.
Final thoughts
Trade mark law does not exist in a cultural vacuum. As language changes, so too must the legal standards applied to it.
This decision may not entirely unf*ck trade mark law, but it certainly nudges the register a little closer to reflecting the way Australians actually speak.

IP and brand lessons from Melbourne Cup Day
Over the weekend the Australian Government finally drew a line in the sand: no special copyright carve-out to let AI developers freely train on Australians’ creative works. In rejecting a broad text-and-data-mining (TDM) exception, the Attorney-General signalled that any reform must protect creators first, and that “sensible and workable solutions” are the goal. Creators and peak bodies quickly welcomed the stance; the TDM exception floated by the Productivity Commission in August met fierce resistance from authors, publishers, music and media groups.
