Descriptive Common Elements Can Be Weighed in Mark–Sign Comparison Without “Double Counting” (Shorts International Ltd v Google LLC)

1) Introduction

In Shorts International Ltd v Google LLC [2026] EWCA Civ 668, the Court of Appeal (Civil Division) (Chancellor of the High Court, Lord Justice Stephen Phillips and Lady Justice Falk) dismissed the appeal of the proprietor of registered marks incorporating “SHORTS/SHORTSTV” against Google’s use of “Shorts” for the YouTube Shorts service.

The appellant (a short-film producer/distributor operating “ShortsTV”) alleged trade mark infringement under s10(2) and s10(3) of the Trade Marks Act 1994 and passing off. The passing off claim and partial revocation issues were not pursued on appeal. The core appellate issues were: (i) whether Google’s use created a likelihood of confusion under s10(2); (ii) whether the appellant had a UK “reputation” for s10(3); and (iii) whether the appellant’s later word mark SHORTSTV was invalid as descriptive/lacking distinctiveness (and whether a “save for short films” limitation could cure any defect).

A central factual theme was the meaning of “shorts” in the relevant market: the trial judge found it extended beyond “short films” to “other short-form audiovisual content”. A central legal theme was how descriptiveness and weak distinctiveness should be handled within the s10(2) confusion analysis—especially at the mark/sign comparison stage.

2) Summary of the Judgment

  • s10(2): No likelihood of confusion. The similarities between the parties’ signs arose mainly from the descriptive element “shorts” (and a play symbol), not from the modest features that gave the appellant’s figurative marks their (low) distinctiveness.
  • s10(3): The appellant failed to prove a UK “reputation” at the relevant date (June 2021). The evidence of exposure/viewing was “paper thin” and the hard numbers were “tiny”. The court therefore did not need to decide difficult issues about sub-categories like “short films”.
  • Validity: The appellant’s word mark SHORTSTV (the “383 Mark”) was descriptive and lacked distinctive character for most registered goods/services (s3(1)(b)–(c)); it had not acquired distinctiveness through use. The proposed “save for short films” limitation failed (unclear category; and in any event did not remove descriptiveness because “shorts” was wider than “short films”).
  • Cross-appeal: Not addressed because Google’s cross-appeal was expressly contingent on Google losing the appeal.

3) Analysis

A. Precedents Cited

Appellate restraint and evaluative trade mark judgments

  • Kynaston-Mainwaring v GVE London Ltd [2022] EWCA Civ 1339; [2023] RTR 17 and Iconix Luxembourg Holdings SARL v Dream Pairs Europe Inc [2025] UKSC 25; [2025] RPC 15 were relied on for the disciplined approach to appeals against factual/evaluative conclusions, especially in trade mark infringement. The Court of Appeal underscored that “likelihood of confusion” is a global evaluative assessment; appellate “foot-fault” challenges to methodology are disfavoured where the overall assessment is properly anchored in the evidence.

The s10(2) framework: use “as a trade mark” and confusion taxonomy

  • Match Group LLC v Muzmatch Ltd [2023] EWCA Civ 454 was used for a clear checklist of the constituent elements of s10(2).
  • Montres Breguet v Samsung [2023] EWCA Civ 1478 supported the requirement that the sign must be used “in relation to goods or services” in the trade mark sense—i.e. to distinguish origin (“as a trade mark as such”), not merely descriptively.
  • Liverpool Gin Distillery Ltd v Sazerac Brands LLC [2021] EWCA Civ 1207 was cited to structure “direct”, “indirect”, and “wrong way round” confusion.

Average consumer, familiarity with the mark, and rejecting a “single meaning rule”

  • Sky plc v SkyKick UK Ltd [2018] EWHC 155 (Ch) was treated as sound authority for the proposition that, in the s10(2) exercise, the average consumer is assumed to be familiar with the earlier registered mark.
  • The court explained that this “familiarity” point aligns with Interflora Inc v Marks & Spencer plc [2014] EWCA Civ 1403, i.e. attention to the consumers for whom the mark is distinctive.
  • Tesco v Lidl [2024] EWCA Civ 262, as approved in Iconix, was used to emphasise that “familiarity” co-exists with imperfect recollection.
  • Tesco v Lidl and Iconix also anchored the rejection of importing any “single meaning rule” (as in defamation) into trade mark confusion: infringement may exist if a significant proportion is confused, but that does not permit rewriting the factual meaning of a descriptive term for the relevant average consumer.

Weak distinctiveness narrows protection

  • Lifestyle Equities CV v Royal County of Berkshire Polo Club Ltd [2024] EWCA Civ 814 and PlanetArt LLC v Photobox Ltd [2020] EWHC 713 (Ch) were cited for the “flip side” principle: low distinctiveness narrows the scope of protection and reduces the likelihood of confusion where the shared element is weak/descriptive.
  • The judgment’s own illustration, Nicoventures Holdings Ltd v London Vape Co Ltd [2017] EWHC 3393 (Ch), reinforced how descriptiveness of a common element (“VAPE”) can prevent confusion even where marks share that element.

Descriptiveness at the comparison stage: Adidas and BSH (KOMPRESSOR)

  • The appellant argued that referencing descriptiveness during mark/sign comparison “double counted” distinctiveness and conflicted with Adidas v Marca Mode (C-102/07). The Court of Appeal distinguished Adidas as addressing a different point: the public-interest “keep free” rationale is a validity issue, not an additional ingredient of the s10(2) test.
  • The appellant relied heavily on BSH Bosch and Siemens v. EUIPO (known as KOMPRESSOR) Case C-43/15. The Court of Appeal held that properly read, KOMPRESSOR prevents a tribunal from treating descriptiveness as a reason to disregard similarity altogether (a binary, preclusive approach). It does not bar a nuanced comparison that recognises high similarity while explaining that what is shared is descriptive and thus contributes little to distinctive origin-significance. L’Oréal v OHIM (C-235/05 P) was noted as reflecting similar concerns about not “disregarding similarity”.

s10(3) “reputation”

  • General Motors Corp v Yplon SA (C-375/97) was applied as the governing test: the mark must be known by a significant part of the relevant public, assessed by market share, intensity, geographical extent, duration of use, and investment.
  • Sky plc v SkyKick UK Ltd [2018] EWHC 155 (Ch) was cited for the proposition that the reputation threshold is “not particularly onerous”, while emphasising it still requires evidence.

Validity and specification-limiting amendments

  • The overlap between s3(1)(b) and s3(1)(c) was anchored in Starbucks (HK) Ltd v British Sky Broadcasting Group plc [2012] EWHC 3074 (Ch) and Agencja Wydawnicza Technopol sp. z o.o. v OHIM (C-51/10 P).
  • The “figurative figleaf” concern from Starbucks was used to contextualise disputes where modest stylisation saves registration but infringement is then asserted against plain-word use.
  • The “non-verbal content insignificant” approach to applying s3(1)(c) to composite marks (word + minor figurative elements) drew on FLYING SCOTSMAN TM [2012] RPC 7 and Caffè Nero Group Ltd v EUIPO Case T-37/16.
  • Content-as-a-characteristic under s3(1)(c) was supported by Linkin Park [2016] 74 and FLYING SCOTSMAN.
  • Compound descriptive marks were analysed through POSTKANTOOR (Koninklijke KPN Nederland NV v Benelux-Merkenbureau (C-363/99)).
  • For negative exclusions/limitations, the court applied POSTKANTOOR and discussed the domestic approach in Omega Engineering v Omega SA [2012] EWHC 3440 (Ch) and Croom's Trade Mark Application [2005] RPC 2, emphasising register clarity and legal certainty.
  • Distinctiveness principles for composite marks referenced OHIM v BORCO-Marken-Import Matthiesen GmbH & Co KG (C-265/09 P), Eurohypo AG v OHIM (C-304/06 P), and acquired distinctiveness guidance was taken from W3 Ltd v easyGroup Ltd [2018] EWHC 7 (Ch). The difficulty of proving acquired distinctiveness for descriptive words was underscored by British Sugar plc v James Robertson & Sons Ltd [1996] RPC 281.

B. Legal Reasoning

1. Meaning of “shorts” and the “familiarity” assumption

The appellant’s key move was to combine (i) the assumption that the average consumer is familiar with the registered mark, with (ii) an asserted “principal meaning” of “shorts” as “short films”, to argue that the judge wrongly treated “shorts” as descriptively referring to YouTube’s short-form user-generated videos.

The Court of Appeal rejected this as an attempt to re-run factual findings under a legal label. The trial judge’s finding was that, for the relevant average consumer, “shorts” already extended beyond “short films” to other short-form audiovisual content. “Familiarity” with the appellant’s mark does not convert the factual meaning of the term into a narrower one, nor does it create a distinct consumer class for whom “shorts” only means “short films” (absent a factual finding to that effect).

2. “Use in relation to goods or services”: descriptive tab labels were not trade mark use

The court upheld the finding that certain “Shorts” uses (e.g. a navigation tab alongside “Home”, “Videos”, “Live”) were understood as describing content categories, not indicating trade origin. The decision illustrates that even where a product feature/service is branded overall (e.g. “YouTube Shorts”), not every appearance of the word necessarily constitutes trade mark use under s10(2).

3. Descriptiveness in the comparison stage: no methodological error

A principal doctrinal contribution of the judgment is its rejection of a rigid sequencing argument that would prohibit referring to descriptiveness when comparing mark and sign. The court accepted that distinctiveness is relevant in the global assessment, but refused to treat mentioning descriptiveness in the comparison discussion as unlawful “double counting”.

The court’s key distinction is between:

  • an impermissible approach that disregards similarity because shared elements are descriptive (the concern in KOMPRESSOR); and
  • a permissible approach that recognises high similarity but explains that what is shared is descriptive/weak and therefore contributes little to origin-indicating force.

The court also cautioned against proliferating “sub-tests” and “rigid methodological criteria” that facilitate appeals based on alleged analytical missteps rather than substantive error in the global assessment.

4. The decisive role of weak distinctiveness in dismissing confusion

The trial judge’s logic, affirmed on appeal, was that the appellant’s figurative “SHORTS” marks achieved registration because the overall combination (including the placement and coloration of a play symbol within the “O”) pushed the sign beyond purely descriptive indications. But infringement failed because Google’s relevant signs shared primarily the descriptive aspects (“shorts” and play-related indicia) and not the (limited) features that made the appellant’s marks distinctive.

The appellant’s argument that consumers might not notice the distinctive placement feature (due to small-screen use and imperfect recollection) was treated as self-defeating: where the mark’s distinctiveness is already low, the inability to perceive one of its few distinctive features does not help establish confusion; it risks “stripping the mark of its distinctive character”.

5. s10(3) reputation: hard evidence mattered

The Court of Appeal endorsed the trial judge’s insistence on concrete evidence of the mark being known by a significant part of the relevant public at the relevant date. The appellant’s evidence (distribution history, channels, festival/publicity activity) lacked robust UK reach/viewing figures for June 2021. Later metrics (e.g. 2024 figures) could not fill the gap. Even under narrower industry “goodwill” findings in passing off, that did not equate to the wider “reputation” required for s10(3).

6. Validity of SHORTSTV and the failure of the “save for short films” amendment

The word mark SHORTSTV was held descriptive: “shorts” described short-form audiovisual content and “TV” described televisual provision; the combination created no perceptible departure from the sum of its parts as required by POSTKANTOOR. The “XTV” naming convention did not help: recognition that channels may be named “XTV” does not show that the term is inherently distinctive absent evidence of consumer recognition of that particular term as indicating trade origin.

The proposed limitation “save for short films” failed on two independent bases:

  • Clarity: “short films” was not a clearly bounded category (length and defining characteristics were disputed/variable); and
  • Insufficiency: because “shorts” was found to be wider than “short films”, excluding only “short films” would not remove the descriptive problem.

C. Impact

  • Methodology in s10(2): The judgment strengthens the permissibility of explicitly recognising descriptiveness (and weak distinctiveness of shared elements) within the mark/sign comparison discussion, provided the tribunal does not “disregard similarity” altogether and still conducts the required global assessment.
  • Navigation/UI uses: It supports the proposition that category labels in user interfaces may be treated as descriptive rather than trade mark use, even where the same term is used elsewhere as part of branding.
  • Evidence discipline for s10(3): Claimants relying on “reputation” must adduce date-relevant, UK-specific exposure evidence (viewership, sales, market share, advertising spend), not merely organisational history or later performance.
  • Specification drafting and amendments: The decision illustrates the difficulty of curing descriptiveness through “negative” or conceptually unstable exclusions, especially where the excluded category is itself unclear and where the descriptive scope of the mark is broader than the carve-out.
  • Strategic lesson for stylised marks: Where registrability depends on modest stylisation, enforcement against plain-word use may face severe headwinds: the very reasoning that saves validity can narrow infringement protection.

4) Complex Concepts Simplified

s10(2) infringement (likelihood of confusion)
A sign infringes if, used as a badge of origin for identical/similar goods/services, it makes consumers think the goods/services come from the trade mark owner (or a linked business). The court assesses this globally through the “average consumer” with imperfect recollection.
“Use in relation to goods or services” / “trade mark use”
Not every appearance of a word is infringement-relevant. If the word is used only to describe a content category (like a menu tab), it may not be functioning as a trade mark at all.
Distinctiveness vs descriptiveness
Descriptive elements tell consumers what the goods/services are like (“short” content), not where they come from. Marks dominated by descriptive matter have weak distinctive character and get narrower protection.
Composite marks and “independent distinctive role”
Where a mark has multiple elements, the court looks at the overall impression. Sometimes one element dominates; sometimes an element retains an independent role. But if the shared element is descriptive, its weight in pointing to trade origin is limited.
s10(3) reputation and “link”
s10(3) protects famous marks beyond confusion. The claimant must prove the mark is known by a significant part of the relevant public in the UK. Only then does the court consider whether the defendant’s sign creates a “link” and causes unfair advantage or detriment.
Invalidity under s3(1)(b)–(c) and “acquired distinctiveness”
A mark cannot be registered if it is purely descriptive or non-distinctive, unless (before filing) it has come to be recognised by consumers as indicating that goods/services come from one undertaking. For descriptive words, strong evidence is typically required.
Negative limitations (“save for …”)
Narrowing a specification must keep the register clear. Exclusions that are unclear, or that carve out an unstable/subjective category, can be rejected for lack of legal certainty—especially if they do not actually remove the descriptive scope of the mark.

5) Conclusion

[2026] EWCA Civ 668 is a claimant-unfriendly decision in descriptive-mark disputes, but it is primarily significant for clarifying analytical discipline: a tribunal may (and often should) acknowledge that shared elements are descriptive/weak when explaining similarity, without falling into “double counting” or ignoring the global assessment. The case also reiterates that s10(3) reputation must be proved with date-appropriate market evidence, and that attempts to “fix” descriptiveness by carving out vague exclusions like “save for short films” will struggle where the carve-out is unclear or under-inclusive.
