It is a first look, not a clearance search: it does not cover common-la

Counts and previews USPTO marks by record attributes (drawing type, standard-character claim, Nice class, status, and combinations of these), with breakdowns by mark type, standard character and class, plus how complete the underlying data is. Claimed-color criteria can be combined with these attributes; counts by color alone, rankings, lists and color vocabulary are outside its scope.

USPTO design vocabulary is literal and narrow: it records "Bands, straight" where a person says "stripe", and has no entry for words like "swoosh", so a plain shape word resolves to a code through mod

Answers questions such as which marks disclaim a word or which marks are described as stripes. Modes: count, top_terms, top_ow

Searches USPTO trademarks by name (14M records) and returns the closest whole-mark matches, ranked by similarity and prefix. It is not an exhaustive contains-search: multi-word marks that only contain the queried word rank low and are often cut (a KWIK query can miss KWIK REWARDS or KWIK KOPY); search_marks_by_pattern returns complete lists. A short result does not show that a name is absent from

Use for broad proceeding discovery by party name, exact 8-digit proceeding number, 8-digit trademark serial number, or 7-digit registration number.
