Trademark monitoring
How to monitor trademark misuse online
A practical watch routine for your marks across registers, domains, search ads, marketplaces and social platforms, and who acts on what you find.
Key takeaways
- Registration does not police your mark; the USPTO says enforcement is on you.
- Register watches catch conflicting filings while opposition is still possible.
- Google Ads does not restrict trademarks as keywords, only in some ad text.
- Marketplaces and platforms have their own reporting routes for rights owners.
- Oppositions, UDRP complaints and legal letters belong with counsel.
To monitor trademark misuse online, watch five places on a set rhythm: trademark registers for conflicting filings, new domains and certificates, search ads, marketplaces and social platforms. Keep evidence for every finding, use each platform's own reporting route for clear cases, and send oppositions, disputes and legal letters to counsel.
Why monitor a registered trademark?
A registration gives you rights, but nobody enforces them for you. The USPTO says it plainly: "You are responsible for enforcing your rights if you receive a trademark registration."[1] The office also expects owners to keep a registration alive with maintenance filings, and missing them leads to cancellation or expiration.[1]
Online, misuse shows up in more places than a legal team can check by hand: new trademark filings, domains, search ads, marketplace listings and social profiles. Monitoring is the routine that finds it early and sends each case to the right owner.
Definition
Trademark monitoring is the ongoing search of trademark registers and online channels for uses of your marks, or confusingly similar ones, that you did not authorize, with a record of what was found and what was done.
What should you watch first?
Start with a written list before any tool. It should hold:
- Your marks. Word marks, logos and product names, with the registration number, office and classes for each.
- Your channels. Official domains, social handles, marketplace storefronts and authorized resellers.
- Close variants. Common misspellings, abbreviations and the mark combined with words such as "login", "support" or "sale".
The list of authorized channels matters as much as the marks. Without it, every reseller or partner page looks like a possible infringement.
How do you watch trademark registers?
Watch new filings so you can object before a conflicting mark is registered. Timing is tight. In the US, once an application is published in the Trademark Official Gazette, a party who believes it would be harmed has "30 days from the publication date" to file an opposition or ask for more time.[1] Other offices set their own periods, so check each one where you hold rights.
For wider coverage, WIPO's Global Brand Database gives access to international marks under the Madrid System and to trademarks from participating national and regional offices.[2] WIPO's Madrid pages also point to Madrid Monitor for following international registrations, including competitors' marks.[3] Whether to oppose a filing is a decision for your trademark counsel.
How do you watch domains and certificates?
New domains that contain your mark are often the first sign of a phishing site or a fake store. Check misspellings, other endings, added words and characters from other alphabets that look the same on screen. Our guide to typosquatting protection covers how to build that list.
Certificate Transparency adds an early signal. It works by "publicly logging the existence of Transport Layer Security (TLS) server certificates",[4] so a watch on those logs for your mark can flag a site before it goes live. For a domain registered and used in bad faith, ICANN's dispute policy allows only cancellation or transfer,[7] and the complaint is filed by counsel or a specialist firm.

What about search ads that use your brand?
Know what the platform restricts before you report. Google's trademark policy lists "using trademarks as keywords" among the things it will not restrict.[5] Restrictions apply to the trademark used in the ad itself, and the policy notes that it "must be used in the ad, not only on the ad's landing page".[5]
Exceptions matter too. Ads for resellers of the genuine product and informational sites are generally not restricted, while ads from direct competitors or ads that use the mark in a confusing way can be.[5] Google accepts complaints only against specific advertisers identified by their URLs.[5] So run regular searches on your brand terms, record the ad text and landing page, and file a complaint where the ad text is the problem.
How do you watch marketplaces?
Marketplaces give rights owners their own tools, usually tied to a registered or pending mark. Amazon Brand Registry, for example, requires "an active registered trademark or a pending trademark registration" from approved offices, and enrolled brands can use its Report a Violation tool even without a selling account.[6]
Check your authorized seller list against live listings, look for your logo on products you do not make, and keep screenshots with dates and listing IDs. Unauthorized reselling of genuine goods and counterfeits are different problems with different routes, so record which one you think you have.
Who should act on what you find?
Sort each finding by risk and owner:
- Phishing or credential theft. Security team first, with abuse reports to the registrar and host. See domain takedown procedures.
- Platform policy breaches. The platform's own reporting route, with the evidence attached.
- Conflicting filings, disputes and legal letters. Counsel or a specialist firm you contract with.
We do not file takedowns, oppositions or legal actions. Our trademark monitoring service sets up the watch list, the routine and the evidence log as part of our digital asset security work, and our brand protection guide shows how it fits with anti-phishing.

FAQ
Trademark monitoring FAQs
Google's trademark policy lists using trademarks as keywords among the uses it does not restrict. Its restrictions apply to trademarks used in the ad itself, and it reviews complaints from trademark owners against specific advertisers. Whether a competitor's ad crosses a legal line elsewhere is a question for counsel.
