In a system often viewed as register-centred, the UK’s robust framework of unregistered rights continues to present a quietly powerful, and sometimes overlooked, risk.
Businesses focusing solely on registered intellectual property rights may underestimate the disruptive potential of claims based on goodwill, reputation, and prior use.
The Legal Landscape: More Than Just the Register
The UK legal system offers significant protection to unregistered rights, most notably through the doctrine of passing off. To succeed, a claimant must establish the classic trinity: goodwill, misrepresentation, and damage. Unlike registered rights, which confer exclusivity through formal registration, unregistered rights arise organically through use in the marketplace.
Goodwill, the attractive force that brings in custom, is crucial. It is territorial, fact-specific, and often more nuanced than the neat boundaries of a registered trade mark or design. This creates both opportunity and uncertainty: rights may exist where the register suggests none.
Registered and Unregistered Rights: Bridging Protection Gaps
Registered and unregistered rights frequently co-exist in parallel, but not always harmoniously. A registered right is a powerful asset, but it does not always provide absolute immunity. It can still face challenges or conflicting claims. A registrant may face opposition or infringement claims based on earlier unregistered rights, particularly where goodwill can be demonstrated.
Equally, unregistered rights can fill strategic gaps, for example, when branding evolves beyond the scope of a registered trade mark or design, or where businesses operate in niche or local markets without acquiring formal protection.
Evidential Expectations: The Real Hurdle
While unregistered rights are flexible, they are evidentially demanding. Claimants must substantiate goodwill with clear and robust evidence and information such as sales figures, marketing materials and spend, customer reach, and geographic extent.
This burden can be decisive. Unlike a registration certificate, which speaks for itself, unregistered rights must be built on a case-by-case basis. Weak or poorly documented use can quickly unravel an otherwise credible claim. Precision matters: success hinges entirely on the strength of the evidence.
When Unregistered Rights Prove Their Worth
Unregistered rights often come into play in disputes involving:
· Early-stage brands that have not yet secured registration,
· Local businesses with a strong regional reputation,
· Rebranding exercises where legacy goodwill persists,
· Tackling product lookalikes and imitations in the marketplace where registered rights may not provide sufficient coverage,
· Filings where a third party seeks to appropriate an established yet unregistered sign.
In such cases, passing off can provide a critical remedy where the register is silent.
For example, in Reckitt & Colman Products Ltd v Borden Inc (Jif Lemon), the Court protected the distinctive lemon-shaped container as goodwill-rich get-up despite limitations in registered trade mark protection, illustrating how passing off can extend beyond the limits of registration.
Similarly, in United Biscuits (UK) Ltd v Asda Stores Ltd (Penguin v Puffin), the Court upheld the passing off claim based on misleading packaging for chocolate-coated biscuits’ packaging, even where registered trade mark claims were not the primary or successful route.
These cases reinforce that, where goodwill is established, passing off remains an essential tool to protect branding when formal registration may fall short.
Mitigating the Risk: Practical Steps
Given their latent nature, unregistered rights require proactive management:
· Go beyond the register: Clearance searches should extend to marketplace use, online presence, trading names, domain names, and industry-specific directories.
· Document use: Maintain records of branding, sales, and marketing to support any future claim to goodwill.
· Consider early registration: While unregistered rights offer protection, registration provides certainty and procedural advantages.
· Monitor the market: Identify potential conflicts early, particularly, in sectors where informal or local trading is common.
Conclusion
Unregistered rights remain a distinctive feature of the UK legal landscape. They are powerful, but inherently uncertain and at times difficult to support. For rights holders and applicants, the key risk lies not in their existence but in their invisibility. A strategy that fails to account for them is not merely incomplete - it may be exposed. In a jurisdiction where unregistered earlier use can trump registration, the register is only ever part of the story.
