Search public trademark information by keyword and review matching records, application numbers, classes, dates, applicants, and reported status.
This tool searches public trademark information by keyword and returns matching records in pages. A successful response contains the keyword, page number, page size, total matches, and a list of records. The published sample may include a trademark name, application number, class, application date, announcement information, agent, applicant, status, and an image address. Fields can vary by record, so use the actual returned response as the reference.
Keyword is required. Enter the trademark text, a brand name, or a meaningful fragment. The upstream search endpoint also requires pagenum and pagesize: pages start at 1 and the documented defaults are 1 and 10. ismatch is optional: 0 performs a keyword search and 1 requests an exact match. When spelling, spaces, punctuation, abbreviations, or variants are uncertain, begin with a keyword search.
When status is 0, result.total is the match count and result.list is the current page. Do not compare names alone. Read name, regno, classid, appdate, registrant, and status together. In the upstream sample, regno is the application-number field and classid is the international class field. Empty, masked, or absent fields must not be inferred or filled in by the user.
Short or common terms can produce many results. Start with page 1 and then change pagenum to continue through the result set. A missing record on the first page is not proof that it does not exist. Exact matching can reduce noise when the full wording is known, but it also narrows the result set. If it returns nothing, switch back to keyword search and try the core wording without suffixes, spaces, or punctuation.
Results are a third-party service response at the time of the query and can be affected by synchronization, indexing, wording, page position, and service availability. This search response is not a complete trademark dossier or a final confirmation of rights. It does not automatically evaluate figurative marks, goods and services, priority, assignments, licences, oppositions, or litigation materials.
This tool is for information lookup and preliminary research only. It does not provide registrability opinions, similarity or infringement analysis, appeal strategy, enforcement advice, or any other legal conclusion. A returned name, class, number, or status does not establish that a mark can be registered, that use is non-infringing, or that a right is valid. For filing, launch, licensing, transactions, disputes, or litigation, verify the latest official public record and obtain qualified professional advice.
If no result is returned, check spelling and try a shorter core keyword; if exact match was selected, try keyword search. If too many records are returned, page through them or refine the wording. If a field differs from your own material, compare the application number, class, applicant, and dates as a set. A failed response is not proof that the mark does not exist; try again later and verify through official channels when needed.
