Checking 500 networks is breadth. Clearance is depth.
KnowEm is built for reach — it looks up a name across hundreds of social platforms. When it comes to the legal question, it points you at a basic trademark lookup. Pentonym makes that the main event.
KnowEm scans a name across a large number of social networks and offers profile-creation and a basic trademark lookup as add-ons. Pentonym focuses on clearance: a US trademark screen with likelihood-of-confusion analysis, plus domains, handles, web use and cultural flags — returned as one signed verdict.
A register lookup isn’t a clearance
KnowEm is good at
- Breadth across hundreds of social networks
- Reserving profiles at scale
- A quick existence check on the register
Seeing whether an exact mark exists on the register is a lookup. Deciding whether your name conflicts — same class, similar sound, senior rights — is clearance. Pentonym does the second, keeps the handle breadth you’d use KnowEm for, and signs the result.
Common questions
Is KnowEm’s trademark check a full clearance?
It’s primarily an existence lookup on the register. A full clearance weighs likelihood of confusion in your class and considers common-law use — which is what Pentonym’s trademark axis does.
Does Pentonym check social handles too?
Yes, across the developer and social platforms that matter for a brand — as one axis of a signed five-axis verdict, not the whole product.
