Disclaimer

TrademarkSentry is an informational service. We monitor public trademark filing data (USPTO TSDR and other public IP registries) and notify subscribers when new filings match the similarity criteria they have configured.

We are not a law firm. TrademarkSentry's notifications are not legal advice, do not establish an attorney–client relationship, and should not be relied on for legal decisions. Trademark similarity, likelihood of confusion, opposition strategy, and infringement analysis are legal determinations that require a licensed trademark attorney.

What our alerts mean. When you receive an alert, it means a new filing appeared in a monitored database that meets the similarity criteria you set. Our matching is automated and does not constitute a legal opinion. The fact that we surfaced a filing does not mean it is a trademark you can or should oppose; that determination requires legal analysis specific to your mark, jurisdiction, and circumstances.

Algorithmic similarity is not legal similarity. The matching our system performs is pattern-based — overlapping characters, similar phonetics, shared classification. Legal similarity for opposition or infringement analysis is a different question entirely, involving factors like consumer perception, market context, and the multi-factor tests used by trademark examiners (e.g., the DuPont factors in U.S. practice). Two filings can match our criteria without being legally similar; conversely, filings that don't match our criteria may still be legally relevant. An attorney is the only reliable interpreter of the legal-similarity question.

What to do with an alert. Use it to stay informed. If a filing concerns you, consult a trademark attorney for guidance.
