Glossary
The terms that come up in a company-name clearance, in plain language.
Adverse (or adversarial) clearance
Checking a name by actively trying to disqualify it — hunting for every conflict, connotation, and weakness — rather than looking for reasons it might be fine. The goal is to fail a bad name early, cheaply, before money is spent registering entities and buying domains.
Likelihood of confusion
The core test in trademark law (Section 2(d) at the USPTO): whether an ordinary buyer could confuse your name with an existing registered mark, given how similar the names sound and look and how related the goods or services are. A same-sounding name in the same category is the classic conflict.
Nice classification
The international system of 45 classes that trademarks are registered under. Software and tech services mostly live in Class 42 (software engineering, SaaS, IT consulting), Class 9 (downloadable software, data processing), and Class 35 (business services, IT staffing, holding companies).
Trademark crowding
When many similar marks already exist in a class, each one gets only thin, contested protection — and a new applicant faces a higher chance of refusal. “Colour + noun” and “[root]Flow” style names tend to land in crowded space.
Coined vs descriptive mark
A coined (arbitrary/fanciful) mark is an invented word with no dictionary meaning in its field — strong and easy to protect. A descriptive or suggestive mark leans on real words that hint at what you do — weaker, more crowded, harder to own.
RDAP
Registration Data Access Protocol — the modern, structured replacement for WHOIS. DeepNameSearch queries RDAP per TLD to see whether a domain is registered and, if so, when and by which registrar.
Domain delegation (SOA / NS)
A registered domain almost always has nameservers assigned to it (an NS record) and a zone of authority (an SOA record), even if there is no website. Checking for delegation catches parked-but-registered domains that a plain “is there a site?” check would miss.
Registry-reserved / premium domain
A name a registry holds back from open registration — famous trademarks, short strings, or names on a premium price tier. These have no registration record and no DNS, so free tools cannot tell them apart from a genuinely available name; a registrar can.
Digital namespace
A name’s availability across the places a company needs to exist online at once — the primary domain, the alternative TLDs, and the social and developer handles. A name can clear on trademarks and still be unusable because the namespace is taken.
Confusable name
A name a buyer could mistake yours for — a spelling or spacing variant, a homophone, a rhyme, a re-ordered-consonant twist, or a common mispronunciation. Trademark likelihood-of-confusion turns on these as much as on the exact match.
Phonetic (dictation) clearance
Testing whether a name survives being said aloud — over the phone, in a meeting, to a voice assistant. Homophones (Vu / Vue), ambiguous spellings, and sub-brand stutters (“KioSto Studios”) are dictation failures even when the name looks fine written down.
Hard stop
A finding that fails a name outright, regardless of its score: an active same-name company in your category, a critical offensive meaning in a major language, a primary .com owned and used by a direct competitor, or every candidate domain already registered.
