How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

We split this skill into the rules it gives an agent

9 rules. About 0 are common, 6 are distinctive, and 3 are very specific to this project.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

USPTO Trademark Search

Search the United States Patent and Trademark Office (USPTO) database to check trademark availability and get registration details. Uses web search as the primary method — most USPTO and trademark database sites block automated requests.

When to Use

User wants to check if a name/brand is trademarked
User is researching trademark availability before naming a product
User wants details on an existing trademark registration
User asks "is [name] trademarked?" or "can I use [name]?"

Important Disclaimer

This skill provides informational data only — not legal advice. Always recommend the user consult a trademark attorney for definitive guidance. Trademark availability depends on many factors beyond exact-match searches (similarity, likelihood of confusion, goods/services classes, etc.).

Known Limitations

Direct web_fetch calls to trademark databases will not work — they block automated requests:

Source	Direct Fetch	Status
tmsearch.uspto.gov	❌ JS-rendered, no useful content	Blocked
tsdr.uspto.gov	❌ Returns 403	Blocked
trademarkia.com	❌ Returns 403	Blocked
branddb.wipo.int	❌ JS-rendered	Blocked

Web search is the primary (and reliable) approach. Search engines index these databases, so you can find trademark records through web_search queries with site: filters.

Step 1: Web Search for Trademark Records (Primary Method)

Use web_search to find trademark registrations. This is the most reliable approach.

Search USPTO Records

web_search: "BRAND_NAME" trademark site:tsdr.uspto.gov

web_search: "BRAND_NAME" trademark site:uspto.gov

Search Trademarkia (Indexed by Search Engines)

web_search: "BRAND_NAME" site:trademarkia.com

Trademarkia results typically include: mark name, serial/registration number, status (LIVE/DEAD), owner, filing date, and Nice Classification class.

Search Broadly

web_search: "BRAND_NAME" trademark registered

web_search: "BRAND_NAME" site:tmdn.org

What to Look For in Results

TSDR links (tsdr.uspto.gov/statusview/sn... or rn...) → existing trademark record with serial/registration number
Trademarkia listings → status, owner, class, filing/registration dates
Company websites claiming "®" or "™" → claimed/registered marks
Nice Classification class for goods/services — critical for determining if a mark conflicts with your intended use

Step 2: Extract Details from Search Results

Search results from Trademarkia and USPTO typically contain enough detail in the snippet:

Mark name and any design description
Serial number (application) or Registration number
Status: LIVE (active) or DEAD (abandoned/cancelled/expired)
Owner name
Class(es) of goods/services
Filing and registration dates

If you need more detail, try fetching the specific Trademarkia result URL — some individual pages may load, though the search pages are blocked.

Key Status Values

Status	Meaning
LIVE	Active trademark — registered or pending
DEAD	Abandoned, cancelled, or expired
Registered	Fully registered and active
Published for Opposition	Pending — 30-day window for objections
Abandoned	Application was abandoned
Cancelled	Registration was cancelled
Expired	Registration expired (not renewed)

Step 3: Check International Marks (Optional)

For products with international reach, also search:

web_search: "BRAND_NAME" trademark site:branddb.wipo.int

web_search: "BRAND_NAME" trademark international WIPO

Trademark Classes (Nice Classification)

When reporting results, include the goods/services class:

Class	Category
9	Software, apps, electronics
25	Clothing, footwear
35	Advertising, business management
36	Financial services, insurance
41	Education, entertainment
42	Software design, SaaS, tech services

A trademark only protects within its registered class(es). A name can be registered by different entities in different classes.

Quick Check

### Trademark: "BRAND NAME"

✅ No exact matches found in USPTO database.
⚠️ Similar marks exist: [list]
📋 Recommended classes to check: 9, 42 (if software)

**Next steps:** Consider a comprehensive search with a trademark attorney before filing.

Error Handling

No results from web search: This doesn't mean the name is available — it may not be indexed yet, or it may be too new. Note this uncertainty.
Conflicting info across sources: Trademarkia may lag behind USPTO. When in doubt, note the discrepancy and recommend checking the official USPTO site directly.
Too many results: Narrow with class filters or add the specific goods/services category to the search query.

Important Caveats to Always Mention

Common law trademarks exist without registration — a name can be "taken" even if not in the USPTO database
State registrations are separate from federal (USPTO) registrations
International marks may conflict — check WIPO if relevant
Likelihood of confusion matters — similar (not just identical) marks can conflict
Class matters — same name can coexist in different goods/services classes
This is not legal advice — always recommend consulting a trademark attorney
