Questions

How do I install One1 Trademark Risk Check?

Copy the http config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does One1 Trademark Risk Check need an API key?

No required environment variable is listed on this record.

What transport does One1 Trademark Risk Check use?

One1 Trademark Risk Check is reached over HTTP.

When was One1 Trademark Risk Check last checked?

Last checked 2026-10-16. Trademark conflict, logo look-alike and TRO enforcer checks for cross-border sellers.

Ask your AI assistant things like:

"Is the brand name Lumora already registered in the US?"
"Does this Amazon title contain infringing trademarks: Wireless Earbuds Compatible with AirPods"
"Is this logo similar to any registered trademark?" (image URL)
"Does YETI frequently file TRO / Schedule A lawsuits against sellers?"
"I got an infringement complaint citing US serial 78414956 — who is it?"

One1 searches tens of millions of trademark records across dozens of jurisdictions — roughly 32.8M text marks and 57.5M figurative marks — plus a curated list of frequent TRO / Schedule A enforcers.

Tools

Tool	What it does
`trademark_text_search`	Brand name / word vs. registered trademarks (phonetic, visual and semantic similarity)
`listing_scan`	Finds trademark-infringing words in a product title or listing copy, grouped by risk
`graphic_trademark_search`	Reverse image search for similar registered figurative marks (public image URL)
`trademark_lookup_by_serial`	Trademark details, legal status and risk by serial number
`trademark_owner_search`	Trademarks held by an owner / applicant
`trademark_owner_profile`	Whether an owner is a frequent TRO / Schedule A enforcer
`coverage_info`	Data coverage and freshness per jurisdiction (free)

All tools accept country (ISO 3166-1 alpha-2, default US).

Reading results correctly

trademark_text_search.count is the number of nearest neighbours returned (always equals limit), not the number of conflicts. Use has_conflicts / conflict_count.
Call coverage_info first. Where clearance_ok is false, "no match" does not mean a mark is registrable.
Results are for reference only and do not constitute legal advice.

Skills

skills/ contains ready-made workflows (Agent Skills format) that tell an assistant how to chain the tools:

Skill	Use it when
`trademark-preflight`	Checking a brand name and listing title before going live
`logo-conflict-check`	Checking whether a logo looks like a registered mark
`tro-risk-check`	Handling an infringement complaint or a TRO worry

Pricing

Usage is metered in API points on your One1 account. The free plan includes a monthly allowance; coverage_info is always free. See one1.cn.
