Trademark Search
The trademark_search tool searches trademark registrations across 9 global jurisdictions. It supports name-based, owner, number, and fuzzy search modes with status filtering and pagination.
Search types
Section titled “Search types”The searchType parameter controls how your query is matched:
| Type | Behavior | Best for |
|---|---|---|
name (default) | Substring match — “APPLE” also returns “PINEAPPLE” | Finding exact or partial name matches |
owner | Searches applicant/owner name fields | Portfolio analysis, competitor research |
number | Matches application or registration numbers | Looking up a specific filing |
fuzzy | Ensemble similarity scoring (phonetic + visual) | Catching misspellings, similar-sounding marks |
Jurisdictions
Section titled “Jurisdictions”Use the jurisdictions parameter to target specific offices or search everywhere:
- Specific:
["US"],["EU", "GB"],["AU", "NZ"] - All:
["ALL"](default) — queries every configured provider in parallel
Available jurisdiction codes: US, EU, AU, NZ, WIPO, GB, CA, JP, CN.
When searching multiple jurisdictions, results are interleaved round-robin so that each jurisdiction gets fair representation in the output.
Status filters
Section titled “Status filters”The status parameter narrows results by lifecycle stage:
| Filter | Includes |
|---|---|
all (default) | Every status |
live | Registered + pending marks |
dead | Abandoned + cancelled + expired marks |
pending | Applications only |
Basic search example
Section titled “Basic search example”Search for trademarks containing “AURORA” in the US and EU:
{ "query": "AURORA", "searchType": "name", "jurisdictions": ["US", "EU"], "status": "live", "limit": 10}Response:
{ "results": [ { "id": "US-97123456", "applicationNumber": "97123456", "name": "AURORA", "jurisdiction": "US", "status": "registered", "filingDate": "2023-01-15", "registrationDate": "2024-03-20", "niceClasses": [9, 42], "owner": "Aurora Technologies Inc." }, { "id": "EU-018765432", "applicationNumber": "018765432", "name": "AURORA DIGITAL", "jurisdiction": "EU", "status": "pending", "filingDate": "2024-06-01", "niceClasses": [9, 35], "owner": "Aurora Digital GmbH" } ], "pagination": { "hasMore": true, "totalResults": 47 }, "metadata": { "query": "AURORA", "searchType": "name", "jurisdictionsSearched": ["US", "EU"], "totalResults": 2, "executionTimeMs": 1230, "resultsPerJurisdiction": { "US": 1, "EU": 1 } }}Nice class filtering
Section titled “Nice class filtering”Add niceClasses to limit results to specific goods/services categories:
{ "query": "AURORA", "searchType": "name", "jurisdictions": ["ALL"], "niceClasses": [9, 42], "status": "live"}This returns only marks registered in class 9 (software/electronics) or class 42 (technology services). Use nice_class_lookup to explore class definitions.
Owner search
Section titled “Owner search”Find all trademarks owned by a specific entity:
{ "query": "Apple Inc.", "searchType": "owner", "jurisdictions": ["US"], "limit": 50}Owner search results are sorted with exact matches first, then prefix matches, then substring matches. This is useful for portfolio analysis and competitive intelligence.
Number search
Section titled “Number search”Look up a specific trademark by its application or registration number:
{ "query": "97123456", "searchType": "number", "jurisdictions": ["US"]}Number formats vary by jurisdiction. Examples:
- US (USPTO): 8-digit serial number (e.g.,
97123456) - EU (EUIPO): 9-digit number (e.g.,
018765432) - AU: 7-digit number (e.g.,
2345678)
Fuzzy search
Section titled “Fuzzy search”Fuzzy search finds phonetically and visually similar marks. It uses an ensemble of similarity algorithms:
- Jaro-Winkler distance
- N-gram overlap
- Damerau-Levenshtein edit distance
- Jurisdiction-aware phonetic matching
{ "query": "GOOGEL", "searchType": "fuzzy", "jurisdictions": ["US"], "limit": 20}Results include a similarityScore (0-1) and are sorted by relevance. The threshold is 0.7 for marks longer than 5 characters. Fuzzy search also checks approximately 200 famous marks locally, so misspellings of well-known brands are caught even when the API substring search misses them.
Pagination
Section titled “Pagination”For single-jurisdiction searches, the response includes a cursor for pagination:
{ "query": "TECH", "searchType": "name", "jurisdictions": ["EU"], "limit": 20}If pagination.hasMore is true, pass the cursor back to get the next page:
{ "query": "TECH", "searchType": "name", "jurisdictions": ["EU"], "limit": 20, "cursor": "eyJwYWdlIjoxfQ=="}The cursor is an opaque token — pass it exactly as received. Pagination cursors are only available for single-jurisdiction queries. Multi-jurisdiction searches return interleaved results without cursor support.
- Start with name search to see what exists, then use fuzzy search to catch variations you might have missed.
- Owner search is the fastest way to map a competitor’s trademark portfolio across jurisdictions.
- Combine Nice class filters with name search to focus on your industry. Without class filters, you may see irrelevant results from unrelated industries.
- When no results are found, the response includes a
suggestionfield with actionable next steps (e.g., try fuzzy search, check number format). - Results are cached server-side to speed up repeated queries. Cache duration is reduced for partial results (when some jurisdictions return errors).
