Use the United States Patent and Trademark Office’s (USPTO) official Trademark Search system to look up a Nintendo game name or marks associated with a Nintendo owner. Search the wording, broaden to related terms, check owner and goods-and-services fields, then open promising records in TSDR to review their status and documents. A database result is a starting point—not proof that a name is available to use or register.
Where to search for Nintendo trademarks
Start at the USPTO’s trademark search page, which links to Trademark Search. The federal database includes marks that have been applied for as well as registered marks. It is the relevant official starting point for searching U.S. federal records; it does not, by itself, establish that a name is legally available.
How to search a Nintendo game name
- Search the game name as wording. In Trademark Search, choose the wordmark option and enter the title. The USPTO help page explains that the simple wordmark and general-search options search one word at a time. For an exact multiword phrase, use the field-tag or search-builder approach and enclose the phrase in straight double quotation marks.
- Expand the wording. Search important words separately and in combinations. Try plausible alternate spellings and pronunciations, and look for marks that add other wording to the name. An exact-title search is only a preliminary “knock-out” check, not a complete search.
- Search owner information separately. Use the owner-name option or the
ON:field tag. For example, the USPTO help givesON:"John Smith". Check the owner listed on each result rather than assuming every relevant record belongs to the same Nintendo entity. - Look at goods and services. The
GS:field can help search descriptions; the USPTO’s example isGS:"yoga pants". You can also filter by international class—for example,IC:025—but class is only a search aid. Goods or services can be related even when they are in different classes. - Filter for live records when useful. The help page documents
LD:truefor live records andLD:falsefor dead records. Its exampleCM:"happy birthday" AND LD:truecombines an exact phrase with a live-status filter. Substitute the game wording you are checking, and verify what the interface returns. - Open relevant records in TSDR. The Trademark Status and Document Retrieval system (TSDR) provides additional record details and documents. Review the record itself rather than relying only on a search-results tile.
The field tags and syntax above are examples from the USPTO’s Trademark Search help; use the actual game wording or owner name and confirm the results in the current interface.
How to assess results
For each potentially relevant record, compare the overall impression of the marks and the products or services identified in the record. A similar name may matter when the goods or services are related; class numbers alone do not decide that question.

- Goods and services: Read the record’s actual identification and consider how those goods or services relate to your intended use.
- Status: Note whether the record is live or dead. A live mark with similar wording and related goods or services deserves closer review.
- Record history: Use TSDR to examine prosecution or maintenance details and available documents.
The USPTO cautions that “There’s no surefire way to uncover all potentially conflicting trademarks.” A database search can miss relevant information, and the USPTO describes federal searching as one essential part of a comprehensive clearance search. A more complete review may require sources outside the USPTO system; for complex clearance questions, the agency suggests considering a private trademark attorney.

Trademark Search helps identify federal applications and registrations that may be relevant to a Nintendo game name. It does not guarantee that every potentially conflicting mark has been found, and a result’s existence—or absence—does not alone determine whether you can use or register a name. The method here is a search workflow, not a current audit of specific Nintendo game titles or their owners. Individual records and interface features can change, so check the live record and its TSDR details before drawing conclusions.
