What is a trademark knockout search?

A trademark knockout search is an early screening process used to identify obvious conflicts before a company invests in a brand name, product launch, or trademark filing. An AI-assisted knockout search checks the USPTO federal register for identical and confusingly similar marks — across spelling variants, phonetic equivalents, meaning, and related Nice classes — and organizes the closest conflicts, their goods and services, and a §2(d) likelihood-of-confusion read into an attorney-reviewable report. It is a preliminary search, not a full clearance opinion, and it does not guarantee that a mark is available or registrable. It helps legal and brand teams spot issues early and brief a trademark attorney faster, before spending on filing fees or a launch.

Who it’s for

Trademark & IP attorneys

“Client intake is messy — I want a structured first-pass knockout before I open a clearance file.”

Brand & in-house legal teams

“We need to triage a name internally before escalating to outside counsel.”

Founders & e-commerce brand teams

“I don’t know if this brand name can be used — and I don’t want to find out after we’ve printed packaging.”

Cross-border sellers entering the US

“Will my brand draw a US trademark conflict or a marketplace complaint? I want to check before launch.”

How the AI-assisted workflow helps

1
Enter the mark & goods/services
Fill one questionnaire with the word mark (and logo, if any) and the goods or services it will cover.
2
Search the USPTO register
The agent searches across spelling variants, phonetic equivalents, meaning, and related / coordinated Nice classes, and suggests design codes for logos.
3
Organize the closest conflicts
Similar marks are grouped with their goods/services and a §2(d) likelihood-of-confusion read, each flagged HIGH / MED / LOW.
4
Hand a report to counsel
You get an attorney-reviewable knockout report — a faster brief for a trademark attorney, not a clearance opinion.

✓An attorney-reviewable knockout report of the closest conflicting marks
✓Goods/services and class coverage for each conflict

Trademark search FAQ

Is a knockout search the same as a clearance opinion?

No. A knockout search is an early, preliminary screen for obvious conflicts. A full clearance opinion — weighing registrability and risk — should come from a trademark attorney. This workflow produces an attorney-reviewable report to make that step faster.

Does it guarantee my brand name is available?

No. No search guarantees availability or registrability. It surfaces the closest conflicts and a §2(d) read so you and your attorney can make an informed call before filing or launch.

What does it search?

The USPTO federal register, across spelling variants, phonetic equivalents, meaning, and related / coordinated Nice classes. For logos it suggests candidate design codes and checks TSDR status on the top conflicts.

Does it cover state or common-law trademarks?

Not currently. It searches the US federal register only — it does not include state registrations, common-law (unregistered) rights, or true-image design search. Your attorney can extend the search where needed.

What is a §2(d) likelihood of confusion?

Section 2(d) of the Lanham Act lets the USPTO refuse a mark that is confusingly similar to an earlier mark for related goods or services. The report flags marks that could raise that risk so counsel can assess it.
