What it does
Trademark Search is an agent skill from dylanfeltus/skills. Search the USPTO trademark database to check name availability and get registration details. Use when the user wants to check if a name is trademarked, research trademark availability, or look up registration status. No API key required.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Legal & Compliance, covering Intellectual property. The repository describes itself as: A library of AI agent skills for research and design. The licence is MIT.
When your agent uses it
- The user wants to check if a name is trademarked
- Research trademark availability
- Look up registration status
Example prompts
- “/trademark-search”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit b97a48f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
tsdr.uspto.gov
Also links to:
tmsearch.uspto.govtrademarkia.combranddb.wipo.int
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Trademark Search loads about 2k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 753 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- trademark-search
- description
- Search the USPTO trademark database to check name availability and get registration details. Use when the user wants to check if a name is trademarked, research trademark availability, or look up registration status. No API key required.
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.govweb_search: "BRAND_NAME" trademark site:uspto.govSearch Trademarkia (Indexed by Search Engines)
web_search: "BRAND_NAME" site:trademarkia.comTrademarkia 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 registeredweb_search: "BRAND_NAME" site:tmdn.orgWhat 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.intweb_search: "BRAND_NAME" trademark international WIPOTrademark 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.

- [Note relevant classes vs user's intended use]
- [Recommend next steps]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
Examples
Example 1: "Is 'Stellar' trademarked?"
web_search: "Stellar" trademark site:tsdr.uspto.govweb_search: "Stellar" site:trademarkia.com- Review search result snippets for serial/registration numbers, status, class
- Present findings with class info and assessment
Example 2: "Can I use 'NovaPay' for a fintech app?"
web_search: "NovaPay" trademarkweb_search: "NovaPay" site:trademarkia.com- Check results for marks in Class 9 (software) and Class 36 (financial services)
- Present findings and note relevant classes for fintech
Example 3: "Check trademark status for registration number 5678901"
web_search: USPTO trademark registration 5678901- Look for TSDR or Trademarkia links in results with status details
- Present the current status, owner, and class information
