Descriptive Radio Brands: Mere Confusion Is Not Passing Off

1. Introduction and Background

This dispute concerned whether the operator of “Classic Hits Radio”, also branded “Ireland’s Classic Hits Radio”, could prevent Bauer Audio Ireland Limited from broadcasting under the name “Greatest Hits Radio”. Both services targeted an older audience and played music drawn substantially from earlier decades. The claimant maintained that the names were conceptually similar and would cause listeners and advertisers to mistake one station for the other or assume a commercial connection.

The claimant relied on passing off and its Irish registration of the words “Classic Hits”, trade mark number 257944, registered on 9 November 2016. Bauer denied misrepresentation and challenged the registration on two independent grounds: invalidity because the words were descriptive and lacked distinctive character, and revocation because genuine use had not been established.

The commercial concern extended beyond listeners choosing the wrong station. Joint National Listenership Research, or JNLR, figures strongly influence advertising expenditure. The claimant feared that confused survey responses would understate its audience and divert advertising revenue.

Procedural context

• Bauer began broadcasting Greatest Hits Radio on the DAB+ trial network on 16 June 2025.
• The claimant obtained an interim injunction on 20 June 2025, effective from 23 June, restraining broadcasting under that name.
• Bauer subsequently used “GHR”. In an earlier judgment, [2025] IEHC 462, Cregan J held that this fell outside the injunction and that the claimant had not established a fair issue to be tried supporting a fresh injunction against those initials.
• At the substantive hearing, the claimant confirmed that it was no longer pursuing its claims concerning “GHR”.

The final judgment therefore addressed the proposed use of “Greatest Hits Radio” and the validity and use of the claimant’s registered mark. It principally applies established law to descriptive radio branding rather than creating a new tort or an entirely new test of distinctiveness.

2. Summary of the Judgment

The matter was listed for 14 October 2026 to address costs, finalise the order and deal with consequential matters. The judgment did not itself determine costs or specify the operative date of revocation.

3. Passing Off: Legal Reasoning and Precedents

3.1 The classical trinity remains the governing test

The court applied the familiar requirements of goodwill, misrepresentation and damage, including likely damage where preventive relief is sought. The principal Irish authority was McCambridge Ltd v Joseph Brennan Bakeries [2013] ILRM 369, adopting Lord Oliver’s formulation in Reckitt & Coleman Products Limited v Bordan Inc. [1990] 1 W.L.R. 491.

These authorities require more than resemblance between competing products or services. The claimant must establish goodwill associated with identifying material, a representation likely to make the public believe that the defendant’s offering comes from the claimant, and resulting or threatened damage. An erroneous impression of commercial association can also fall within the tort.

The judgment repeatedly distinguishes two propositions:

• People may confuse two descriptive names.
• The defendant may represent its service as originating from, or being connected with, the claimant.

The first does not necessarily establish the second. That distinction determined the passing-off claim.

3.2 Commercial success is not exclusive ownership of descriptive words

The claimant established a successful broadcasting business. The latest JNLR evidence showed a 6.8% market share, with daily and weekly listenership figures of 7.9% and 13.8% respectively in the multicity area. The court accepted that the station possessed valuable goodwill under “Classic Hits Radio” and “Ireland’s Classic Hits Radio”.

However, this did not establish that “Classic Hits” alone had become distinctive of the claimant. The words already described a recognised musical and radio format. The court found that they had not acquired a secondary meaning identifying the claimant’s service rather than describing its content. Audience size demonstrated the station’s success, but did not answer that different legal question. (Judgment, paras. 50–61.)

RJ Reuter v Mulhens [1954] CH.50 explained goodwill as the customer-attracting value of a name and reputation. Muckross Park v Randles [1995] 1 IR 130 emphasised what the relevant public knows a name to signify. These authorities supported the distinction between a valuable business asset and protectable identifying significance in particular words.

The court also considered the claimant’s evolving branding. “Classic Hits” had appeared alongside “4FM” and was later supplemented by “Ireland’s” and “Radio”. Simultaneous use of two longer names did not prevent goodwill from existing, but weakened the argument that the descriptive core had independently become a clear badge of origin. This was an evidential assessment, not a rule that a business can hold goodwill in only one name.

3.3 The policy against monopolising descriptive language

The central authority was Office Cleaning Services Ltd v Westminster Window and General Cleaners Ltd [1946] 63 R.P.C. 39. There, “office cleaning” described the services offered and had not acquired the necessary secondary meaning. The distinction between “Services” and “Association” was sufficient in that context.

The decision establishes a competition-sensitive limit: a trader choosing ordinary descriptive words cannot necessarily prevent competitors from using similar language, even where some confusion results. Otherwise, the first trader could convert useful commercial vocabulary into private property.

Several authorities reinforced that reasoning:

• Cellular Clothing Company v Maxton & Murray [1899] AC 326 explained the particularly heavy evidential burden involved in proving that descriptive words have acquired a secondary meaning. Such proof is possible, but substantially more difficult than establishing distinctiveness in an invented expression.
• Yoplait v Nutricia [2025] IECA 163, referring to Cadbury Schweppes [1981] 1 WLR 193, identified distinctiveness as a safeguard against undue restriction of competition.
• Reckitt & Colman v. Borden [1990] 1 WLR 491 recognised that confusion resulting from lawful use of ordinary trade descriptions does not itself establish misrepresentation.
• Phones 4U v. Phone4u.co.uk Internet [2006] EWCA Civ 244 explained that public policy can require a trader using a descriptive badge to tolerate “mere confusion”.
• Cranford Community College v. Cranford College Ltd [2014] EWHC 2999 (IPEC) clarified that a protectable addition to descriptive words does not allow the claimant to fence off the descriptive words themselves. Its reasoning also addressed similar descriptive ideas expressed through different words.
• Au Vodka Ltd v NE10 Vodka Ltd [2022] EWHC 2371 (Ch) described the court’s task as locating the boundary between tolerable confusion and actionable deception.

The broadcasting analogy in A&E Television Networks v. Discovery Communications [2013] EWHC 109 (Ch) was particularly relevant. The broadcaster of HISTORY failed to prevent use of DISCOVERY HISTORY. A programme or service description does not become exclusively appropriable merely because it also forms part of a successful channel name.

Planet Art v Photo Box [2020] EW HC 713 provided a further qualification. Although “freeprints” had some distinctive significance as a composite expression, that did not confer broad control over the descriptive words “free prints”. The court used the decision to show that even some acquired goodwill may support only narrow protection.

Applied here, “Classic Hits”, “Greatest Hits”, “Hits” and “Radio” remained language that broadcasters could legitimately need to describe their offerings. The claimant could not establish passing off merely by showing that its chosen descriptive formulation resembled another.

3.4 Why the names and surrounding circumstances did not establish misrepresentation

The claimant relied on the shared words “Hits Radio”, the two-syllable first words, overlapping playlists, similar audience demographics and slogans referring to earlier decades.

The court nevertheless found material differences between “Classic” and “Greatest” in appearance, sound and meaning. Uncontested linguistic evidence supported that assessment. Their shared grammatical form and syllable count did not establish the legally relevant similarity alleged.

The surrounding circumstances also failed to establish misrepresentation:

• Playing similar music for a similar audience was legitimate competition.
• Referring in slogans to the decades from which music was selected was ordinarily descriptive.
• The names and slogans were materially distinguishable when actually compared.
• Bauer had used the Greatest Hits Radio brand abroad for years; it had not devised it specifically to imitate the claimant in Ireland.
• Differences in playlists, recorded content and competitions also distinguished the services.

The court was not persuaded that Bauer’s Northern Ireland service had a significant Republic of Ireland listenership. Nevertheless, the brand’s established foreign history remained relevant to whether the Irish launch represented an attempt to appropriate the claimant’s goodwill. Foreign brand history and proof of local goodwill are different questions.

The claimant correctly argued that deliberate deception was unnecessary. The court accepted that principle, but found neither intentional nor unintentional misrepresentation. Its rejection of alleged bad faith therefore supplemented, rather than replaced, its analysis of the service’s likely effect on the public. It characterised Bauer’s “head-on positioning” as ordinary competition, not passing off. (Judgment, paras. 63–84, 170–187.)

3.5 Name-based passing off remains actionable

The judgment does not require copied packaging or visual presentation. Galway Free Range Eggs v O'Brien [2019] IECA 8 established that the evidence may be assessed by reference to the name alone, asking whether the public is really likely to perceive a connection between the businesses.

That principle was supported by:

• O'Neill's Irish International Sports Company Limited v O'Neills Footwear Dryer Company Ltd [1997] IEHC 75: passing off may arise through similarity of name, appearance or other presentation; deliberate intention is unnecessary.
• C&A Modes v C&A (Waterford) Ltd [1976] I.R. 198: a company name can wrongly imply that its business is a branch, subsidiary or associate of an established undertaking.

These decisions established the availability of a name-based claim, but did not dispense with misrepresentation or establish exclusive rights over the descriptive elements of every business name.

Muckross Park Hotel Limited v Kathleen Randles & Dromhall Hotel Company Limited [1995] 1 I.R. 130 illustrated the distinction. The hotel name had acquired a secondary meaning through its history and reputation. Actual confusion, overlapping marketing channels and other contextual features supported passing off. The earlier court also considered that the combined circumstances would justify relief even without secondary meaning.

Jordan J found neither equivalent secondary meaning nor comparable surrounding circumstances here. This preserves an important qualification: the absence of secondary meaning in a descriptive component does not excuse an otherwise misleading overall presentation.

3.6 Threatened damage could not cure the absence of misrepresentation

The claimant’s concerns about advertising revenue were commercially substantial. More than 90% of its revenue came from advertising, and JNLR results heavily influenced advertising decisions. The court also considered it likely that the survey would eventually encompass DAB+ stations.

However, potential economic consequences do not convert lawful descriptive competition into passing off. The claimant still needed to connect threatened harm to an actionable misrepresentation.

Falcon Travel Ltd v The Owners Abroad Group plc [1991] 1 IR 175 established that damage or likely damage can include appropriation of goodwill without proof of quantified financial loss. The discussion in Galway Free Range Eggs v O'Brien, including its reference to the Kilkenny Brewing case, likewise confirmed that actual damage is unnecessary for preventive relief.

The claim therefore failed because misrepresentation was not proved, not because the claimant had to wait for advertising losses to materialise.

4. Evidence: Surveys, Judicial Assessment and AI Search Results

4.1 Survey evidence was useful but did not answer the decisive legal question

The claimant’s survey obtained responses from 1,081 people in its broadcasting area. Its principal findings were that:

• 67% identified Greatest Hits Radio as likely to be confused with Classic Hits Radio.
• 16% reported listening to Greatest Hits Radio during the preceding six months, despite its very limited period on the Dublin DAB+ trial.

Bauer criticised the survey’s wording, insufficient testing of respondents’ knowledge and absence of follow-up questions asking why respondents considered confusion likely.

The court applied a pragmatic rather than perfectionist approach. Hanafin v. Minister for the Environment [1996] 2 I.R. 321 and Jordan v. Minister for Children and Youth Affairs [2015] 4 I.R. 232, discussed through the appellate eggs decision, supported admissibility while leaving weight to judicial evaluation. Relevant considerations included the surveyed population, methodology and the factual question the evidence could actually illuminate.

In particular, Jordan v. Minister for Children and Youth Affairs distinguished the court’s practical task from deciding whether research meets every standard required for academic publication. Imperfect research can assist, provided its limitations are considered.

Jordan J accepted that some criticisms were justified, especially the need for better testing of respondents’ familiarity with the stations. Nevertheless, the survey was not worthless. It gave some indication of public reaction.

Its decisive limitation was substantive: selecting the most similar name from a list did not establish that Bauer was representing its station as connected with the claimant. A high percentage could therefore coexist with failure of the claim. The court considered that the survey showed “mere confusion”.

4.2 The newspaper comparison depended on established distinctiveness

The claimant relied on Associated Newspapers v Express Newspapers [2004] IP & T 378. That decision accepted a flawed survey as a useful indication that proposed newspaper titles would suggest an association with the claimant’s publications.

The distinction was that “the Mail” had acquired distinctive significance in the relevant London market and the proposed competing titles were likely to be abbreviated in the same way. Here, the claimant had not established comparable secondary meaning in “Classic Hits”. The decision supported taking imperfect survey evidence seriously, but did not establish that the claimant’s survey proved actionable deception.

McCambridge Ltd v Joseph Brennan Bakeries also confirmed that actual confusion is unnecessary and that the test is not determined by numerical thresholds. Its references to Singer Manufacturing Company v Loog (1882) 8 App. Cas. 15 and HFSC v Midland Bank [2000] F.S.R. 176 emphasised likely customer impressions, imperfect recollection and the care appropriate to the transaction. Those principles did not remove the requirement for misrepresentation.

4.3 The judge retains independent responsibility

The judgment’s discussion of Parker Knoll Limited v Knoll International Ltd [1962] R.P.C. 265, Spalding & Bros v Gamage Limited [1915] 32 R.P.C. 273 and Payton & Co Limited v Snelling, Lampard & Co Ltd [1900] 17 R.P.C. 635 reinforced that likely deception is ultimately for the court.

Experts, survey respondents and witnesses assist that assessment; they do not determine the legal conclusion. Accordingly, neither the survey’s 67% figure nor an isolated verbal confusion by Bauer’s chief executive compelled a finding of passing off.

4.4 AI-generated confusion: reliability and attribution are separate problems

The claimant produced Google AI search results that incorrectly confused the stations. The court accepted that these outputs were erroneous, but attached limited weight to them.

The reliability difficulties included the small number of examples, variability between searches, absence of evidence about the proportion of accurate results, and uncertainty about how a fully established Irish service would affect future outputs. The court also warned against allowing AI-generated material to displace its own assessment. (Judgment, paras. 74–78.)

Two recent Irish appellate authorities supported caution:

• Guerin v. O'Doherty [2026] IECA 48 discussed fabricated authorities generated by AI and the inherent risk of hallucination.
• Von Geitz v. Kelly [2026] IECA 29 expressed similar concerns about AI-generated material.

There was also a distinct attribution problem. National Guild of Removers v. Bee Moved [2016] EWHC 3192 (IPEC); [2018] EWCA Civ 1302 supported the proposition that a defendant is not responsible in passing off for statements made by independent third parties outside its control.

Similarly, My Kinda Town v. Soll [1983] RPC 407 distinguished misleading journalistic descriptions from representations made by the defendant. Jordan J accepted the substance of Bauer’s argument that independent Google outputs could not, on these facts, supply the missing representation by Bauer.

The finding is not a universal rule excluding AI-related evidence. It identifies two questions that such evidence must confront: whether it reliably demonstrates relevant public perception, and whether the alleged misrepresentation is legally attributable to the defendant.

5. Trade Mark Invalidity: Description Is Not Identification of Origin

5.1 Invalidity and revocation have different effects

The court carefully separated the two counterclaim routes:

• Invalidity under section 52: the registration should not have been made. Under section 52(6), it is treated as never having existed to the relevant extent, subject to transactions past and closed.
• Revocation under section 51: rights cease from the applicable revocation date. Earlier infringement can, in principle, remain relevant.

Both remedies can operate partially where only some goods or services are affected. Invalidation removed the foundation of the claimant’s registered-mark infringement case; the judgment did not undertake a separate, detailed infringement comparison between two valid marks.

5.2 Burden of proof

Bauer initially bore the burden of establishing an absolute ground of invalidity. Once that was established, the claimant bore the burden of proving acquired distinctiveness sufficient to preserve registration.

British Sugar v. James Robertson & Sons [1996] RPC 281 supported this allocation. The proprietor cannot rely indefinitely on the challenger’s initial burden once the original registration has been shown to be defective.

5.3 Lack of distinctive character: section 8(1)(b)

Section 8(1)(b) excludes marks devoid of distinctive character. The essential question is whether the sign identifies services as originating from a particular undertaking and distinguishes them from competing services.

The EU authorities supplied the analytical framework:

• Linde, C-53-55/01, explained the source-identifying function required for distinctive character.
• Mag Instrument v. OHIM, C-136/02P, distinguished inherent distinctiveness from distinctiveness acquired through use. Consumer recognition resulting from familiarity cannot simply be treated as proof that a mark was inherently distinctive.
• Okotoks v. Fine & Country [2013] EWCA Civ 672, applying Lloyd Schuhfabrik v. Klijsen, C-342/97, emphasised the relevance of a sign’s inherent characteristics, including descriptive elements.

The court held that “Classic Hits” communicated the content of the broadcast—popular music from an earlier period—rather than independently identifying commercial origin.

5.4 Descriptiveness: section 8(1)(c)

Section 8(1)(c) separately excludes signs consisting exclusively of indications capable of describing characteristics of the relevant services.

Agencja Wydawnicza v. OHIM, C-51/10P, explained the public interest in keeping descriptive signs freely available. Actual descriptive use at the application date is unnecessary if the expression could serve that function. Nor must competitors prove an immediate need to use it or the absence of alternative terminology.

Here, the evidence went further than potential descriptiveness. “Classic hits” had long been used as a radio-format description. Historical broadcasting use, media references, industry evidence and the claimant’s own documentation supported that conclusion.

Especially significant was a 2011 letter from the claimant’s trade mark agents expressly describing “Classic Hits” as “totally generic” when responding to an earlier registration objection. The court treated this as evidence supporting the expression’s ordinary meaning, rather than as a separate legal bar preventing the claimant from advancing its case.

The registration therefore failed under both sections 8(1)(b) and 8(1)(c).

5.5 Acquired distinctiveness: use is evidence, not the conclusion

The claimant invoked section 52(1), which can save a registration if the sign acquired distinctive character through use before the invalidity application. The relevant date was 31 July 2025, when Bauer delivered its original counterclaim.

The claimant relied on audience figures, marketing, industry references, abbreviated station names, website material, advertising rate cards and in-car displays. The court accepted that “Classic Hits” sometimes referred to its station, but held that contextual abbreviation did not establish the required independent source-identifying significance.

British Sugar v. James Robertson & Sons warned against assuming that “use equals distinctiveness”. Bach Flower Remedies [2000] RPC 513 similarly required use in a distinctive sense: increased exposure alone does not prove that the public treats a descriptive expression as a badge of origin.

The claimant’s own evidence was damaging. A senior executive described how “Classic Hits” alone failed to tell people clearly what business was contacting them, helping explain the addition of other words to the brand. The court considered that the underlying problem had not been overcome by the relevant date.

The comparison with Dryrobe Ltd. V Caesr Group Ltd (t/a D-Robe Outdoors) 2025 EWHC 3167 (IPEC) did not alter the result. That decision assessed sales, market position, publicity, marketing, direct consumer evidence and actual confusion before finding acquired distinctiveness. Its reference to Oska's Trade Mark [2005] RPC 20 explained how press coverage can both demonstrate and increase public recognition.

Jordan J accepted that such evidence could matter, but found it insufficient here. The contrast was evidential and contextual; it did not establish that descriptive words can never acquire distinctiveness.

Bauer also objected that post-registration acquired distinctiveness had not been specifically pleaded. The court noted the omission but treated the pleading dispute as academic because the evidential case failed in any event. It therefore did not establish a decisive procedural ruling on whether the argument could properly be introduced in closing submissions.

6. Revocation for Non-Use: A Separate Evidential Failure

The court independently found that the claimant had not proved genuine use under section 51(1)(a). Section 99 placed the burden of proving use on the proprietor.

The authorities explained both that burden and the required evidence:

• Centrotherm v. OHIM, C-610/11P, justified the proprietor’s evidential responsibility by procedural efficacy and common sense.
• Ferrari v. DU, C-720/18/C-721/18, recognised that the proprietor is best placed to prove use. It also required attention to independent subcategories within broad goods or services specifications.
• Ansul v. Ajax, Case C40/01, distinguished genuine market use consistent with the mark’s origin function from token activity intended merely to preserve registration.
• Kabushiki Kaisha Fernandes v. OHIM, T-39/01, required solid and objective evidence, rather than probabilities or suppositions.

The registration covered services in Classes 35, 38 and 41. The claimant did not adequately address the individual services and independent subcategories. For example, organising, producing and presenting shows, competitions, games, concerts and events could not simply be treated as one undifferentiated activity.

The court also found that the evidence did not show “Classic Hits” performing the essential function of a trade mark. Occasional abbreviation of the longer station names and continued commercial broadcasting did not, on its assessment, establish genuine use of the registered sign.

This reasoning requires careful handling. Distinctiveness, acquired distinctiveness and genuine use are separate legal questions, even though the same evidence may bear on each. The judgment links them closely because the claimant’s evidence failed to establish source-identifying use. It should not be read as a general holding that every descriptive mark is incapable of genuine use or that every use within a longer brand is legally ineffective.

7. Significance, Impact and Limits

7.1 Descriptive branding offers commercial clarity but narrower exclusivity

The decision illustrates the trade-off in choosing a name that immediately tells customers what a business supplies. Such a name may be commercially useful, yet difficult to protect against competitors using similar descriptions.

Future claimants will need to isolate the identifying significance they claim. Evidence that the business is successful, or that industry participants understand an abbreviation in context, may not establish exclusive rights in the descriptive words themselves.

7.2 Confusion evidence must address its legal cause

The case demonstrates why survey design must follow the legal issue. A survey asking which names are likely to be confused may establish similarity without showing a perceived common source or commercial connection. Methodological perfection is unnecessary, but relevance to misrepresentation is essential.

7.3 AI output is neither conclusive public perception nor automatically the defendant’s speech

The judgment offers a useful framework for future disputes involving AI search summaries: assess reliability, representativeness and attribution separately. An inaccurate automated answer cannot simply substitute for proof that the defendant’s conduct misleads the public.

7.4 Trade mark portfolios require evidence matched to their specifications

Broad registrations carry corresponding evidential risks. Proprietors facing non-use challenges should be able to connect objective market evidence to the protected services and relevant independent subcategories. General proof of an active business may not suffice.

7.5 The holding should not be extended beyond the issues decided

• The decision does not abolish passing-off protection for descriptive brands that acquire sufficient identifying significance.
• It does not make deliberate intention a necessary ingredient of passing off.
• It does not exclude survey evidence merely because the methodology could be improved.
• It does not provide immunity for every third-party statement regardless of responsibility or control.
• Although intentional interference with economic interests appeared among the pleaded claims, the judgment did not separately develop a substantive ruling on that tort.

8. Complex Concepts Simplified

Passing off

Misleading the public into thinking that one business’s goods or services come from, or are connected with, another established business.

Goodwill

The customer-attracting value of a business’s reputation and identifying features. A successful business does not necessarily own every descriptive word in its name.

Secondary meaning

A descriptive expression acquires an additional significance: the relevant public recognises it as identifying a particular commercial source.

Mere confusion

Confusion that does not establish actionable misrepresentation, particularly where it results from legitimate use of ordinary descriptive language.

Quia timet relief

Preventive relief against sufficiently likely future harm. The claimant need not wait until damage occurs.

Acquired distinctiveness

Source-identifying significance developed through use, rather than existing inherently in the expression.

Genuine use

Real market use of a mark in its trade mark function, not merely token activity or unsupported assertions of use.

Invalidity and revocation

Invalidity generally treats registration as never having existed; revocation terminates rights from the applicable date.

9. Conclusion

The judgment’s central lesson is that similarity, goodwill and possible loss do not replace proof of misrepresentation. The claimant had a successful radio station, but had not established exclusive identifying significance in “Classic Hits”. Bauer’s descriptive branding therefore did not amount to passing off.

The trade mark counterclaim reinforced the same competitive concern through distinct statutory rules: descriptive registration required proof of acquired distinctiveness, and continued protection required proof of genuine use. Neither was established. The decision preserves protection for genuine commercial identity without allowing descriptive vocabulary to become an unwarranted barrier to competition.
