Harper James advises UK businesses on protecting and enforcing trade marks under the laws of England and Wales. Brand enforcement involves identifying unauthorised use, assessing the legal basis for action, and selecting a response that reflects the value of the brand, available evidence, cost and commercial priorities.
Start with an accurate register of the organisation’s trade marks, logos, product names, domain names and key social media handles. Check the relevant classes, territories, owners and renewal dates. A registered trade mark generally provides a clearer basis for enforcement than an unregistered brand. Unregistered rights are usually enforced through the law of passing off, which requires evidence of goodwill, misrepresentation and damage.
Monitoring should cover trade mark applications, company names, domain registrations, online marketplaces, search results, social media and competitor advertising. A trade mark monitoring service can identify potentially conflicting applications during the opposition period, when an objection is usually more efficient than later court proceedings.
Record the first date the use was found, the identity of the user, the goods or services involved, the relevant territory and the likely customer confusion. Preserve screenshots, web pages, invoices, advertisements and correspondence in a dated evidence file. Compare the marks and the goods or services rather than focusing on visual similarity alone. The assessment also considers the strength of the existing mark, the scale of the other use and whether the use has caused or threatens commercial damage.
The available response ranges from an informal contact to a formal letter before action, trade mark opposition, platform complaint, domain name dispute procedure or court claim. A formal letter normally identifies the rights relied on, explains the alleged infringement, sets out the required steps and specifies a deadline. The proposed remedy should be proportionate. An undertaking to stop using the mark may resolve a limited dispute, while a continuing or commercially significant infringement requires a more structured enforcement plan.
Before sending correspondence, confirm ownership, registration details, contractual rights and any coexistence arrangements. Consider whether the other party has a defence, such as descriptive use, consent, honest use of its own name or an earlier right. Keep communications consistent across trade mark offices, platforms and the opposing party. Record decisions, deadlines and costs so that the board can assess whether escalation remains commercially justified.
A brand enforcement policy should allocate responsibility for monitoring, evidence collection, approvals and external correspondence. It should also set thresholds for issuing a trade mark opposition, sending a letter before action or starting litigation. This turns enforcement from a reaction to individual incidents into a repeatable process that protects the brand while controlling legal spend.
