What do the risk levels mean?

Each search result gets an adjusted risk score between 0 and 1, and the score is bucketed into one of three plain-English levels: High at 0.7 and above, Medium at 0.6 and above, Low below 0.6. The same buckets drive both the per-result badges and the overall verdict banner at the top of the results page.

The score itself is the visual similarity from the AI match multiplied by a status multiplier and a Nice class multiplier. The status multiplier reflects legal enforceability: Registered marks weigh in at 1.0 because they are presumed valid and actively enforceable, Pending marks at 0.85 because they may still register, Canceled marks at 0.25 because they retain only prior-use signal, and Abandoned marks at 0.15 because the original owner gave up rights. The class multiplier reflects commercial proximity under DuPont Factor 2: identical Nice class with the user's chosen industry is 1.0 (direct competition), commercially adjacent classes are 0.7, and unrelated classes are 0.3. The overall verdict for the search is dominated by the highest-risk single match, because in trademark law one strong conflict is enough to create real exposure even if the rest of the results look clean.

In practice, this means a 90% raw visual match against an Abandoned mark in an unrelated class can land squarely in Low (0.9 × 0.15 × 0.3 ≈ 0.04), while a 65% match against a Registered mark in your exact Nice class can land in High (0.65 × 1.0 × 1.0 = 0.65 — close to the High threshold and likely pushed over by the live-mark bonus in the overall score). The model is calibrated so that conflicts that would actually cost you a takedown, an opposition, or a rebrand surface as High; conflicts that share aesthetic DNA but live in different commercial worlds correctly drop down the list.

A High verdict is your signal to stop and redesign or to bring in a trademark attorney before you spend more on the brand. Medium means the conflict is real enough to investigate before committing — modify the differentiating elements, narrow your Nice class strategy, or get a second opinion. Low means proceed with normal originality discipline; the surfaced marks are worth knowing about but not blocking. Either way, treat the levels as screening indicators, not legal determinations of infringement — a likelihood-of-confusion opinion under Lanham Act § 2(d) is something only a qualified attorney can issue.
