AI trade mark watching and enforcement

Aipedia, by the Apex broking team · Last reviewed 2026-10-27

AI watch services can monitor trade mark registers and online marketplaces at scale, but they can miss conflicting applications and flag harmless ones. A missed opposition window or an overreaching threat letter can each lead to a claim against the attorney.

Part of: AI in patent and trade mark attorneys

In short

Trade mark attorneys use AI watch services to spot conflicting applications and online monitoring to find infringements, counterfeits and "starjacking", which CITMA's 2025 report names as an AI-enabled IP crime. Risks run both ways: a missed application means a missed opposition window, while a false positive acted on without checking can lead to a threat letter that is unjustified. IPReg's AI guidance points to existing duties of competence, supervision and client information. A client's claim against the attorney for a missed deadline or bad enforcement advice usually falls under PI, subject to the policy terms.

How AI is used in watching and enforcement

Watch services compare newly published trade mark applications against a client's marks and flag those that may conflict, so that the client can decide whether to oppose within the time allowed. AI improves recall across languages, transliterations and device marks, and ranks results by risk. Online brand monitoring goes further, scanning marketplaces, social media, app stores and domain registrations for infringing use and counterfeits.

CITMA's report on AI's impact on IP practice (July 2025) flags new AI-enabled IP crime, including "starjacking" and AI-assisted counterfeits, which may increase demand for automated monitoring. It also stresses that AI output must always get human review.

The duties that apply

IPReg's AI guidance (final from 20 July 2026) relies on existing duties in the Core Regulatory Framework: competence, supervision, client information and records.
Be clear with clients about what the watch covers: which registers, classes, mark types and territories, and who decides whether to act.
Watch reports reviewed by paralegals need attorney oversight on judgment calls.
CITMA's procurement guidance helps assess watch vendors, including service levels and liability terms.

What can go wrong

Missed oppositions. A watch tool scores a conflicting application below its reporting threshold, or a report is generated but not acted on. The opposition period passes. The client may then have to bring invalidity proceedings later, at greater cost and with less certainty, or live with a conflicting registration.

False positives and threats. Online monitoring flags a seller as infringing. A letter goes out without anyone checking the goods, the seller's rights or whether the use is in the UK. UK intellectual property law contains unjustified threats provisions, under which a person aggrieved by certain threats of infringement proceedings may seek remedies. A client facing such a claim may look to the attorney who advised it.

Illustrative scenario: a firm runs automated takedown requests and letters from AI monitoring results for a fashion client. Several targets turn out to be legitimate resellers of genuine goods. One brings a threats claim against the client and the client claims its costs from the firm, saying it relied on the firm's process.

How PI usually responds

Missed-deadline claims, such as a lost opposition window, would usually fall within IPReg-compliant PI as negligence, subject to the policy terms; the loss may be the extra cost of later proceedings or the reduced value of the client's mark. Where a client faces a threats claim and blames the attorney's advice, the client's claim against the attorney would usually be treated as a negligence claim too, but the threats claim against the client is not covered by the attorney's PI. If the attorney was the sender of a threat, how the policy responds depends on the wording. Notify a circumstance as soon as a missed window or a disputed letter comes to light. See PI for trade mark attorneys.

Practical controls

Agree and record the watch scope and reporting thresholds with each client.
Diarise opposition deadlines from every report, whether or not the client is expected to act.
Get written client instructions not to oppose, and keep them.
Check flagged online use by a person before any letter or takedown is sent.
Review template letters for threats risk, and keep automated messages to permitted forms.
Keep watch reports and decisions on the client file.

Frequently asked

Who is responsible if an AI watch service misses an application?

The attorney who offered the watch is usually responsible to the client for the service, even if a vendor ran the tool. Clear terms on scope and thresholds, and vendor contracts that allocate liability, help manage this.

Can a threat letter based on AI monitoring cause problems?

Yes. UK IP law has unjustified threats provisions, and a letter sent on an unchecked AI flag may give the recipient a claim. Check each target's goods, rights and location before sending, and use permitted forms of communication.

Does PI cover a missed opposition deadline?

Usually, subject to the policy terms, as a negligence claim. The loss may be the extra cost of later invalidity proceedings or the reduced value of the client's rights. Prompt notification and good records help.

Should clients be told the watch uses AI?

IPReg's guidance relies on existing duties to give clients clear information. Telling clients what the watch covers, how results are filtered and who decides whether to act matters more than naming the technology.
