What do the risk levels mean?

The verdict at the top of a LogoVerify result is the answer to one question: is there a live USPTO mark close enough to your name or your design, for goods like yours, that an examiner or its owner could stand in your way? It reflects the most serious conflict found, because in trademark law one strong conflict is enough, however clean the rest of the list looks.

Three things decide it. How close the other mark is: for a design, what the AI saw when it put the two logos side by side ("Looks close", "Some overlap", "Looks different"); for a name, whether it is the same word, a close spelling or a sound-alike. Whether the other mark is alive: registered and pending marks count; cancelled and abandoned marks rarely block anyone. And whether it covers goods like yours: the same class is direct competition, related classes are close behind, unrelated classes carry little weight. You pick what you sell, and the check weighs every match against it.

Likely conflict means all three line up: a live mark, close to yours, for the same or related goods. This is your signal to change the name or the design before you spend more on it, or to bring in a trademark attorney if you want to go ahead anyway.

Possible conflict means something is close but not all three line up: the mark is for related rather than identical goods, the overlap is partial, or the match is strong on one channel and weak on the other. Read the reasons on the result, look at the logos side by side, and decide; it is often a case for adjusting one element rather than starting over.

Depends on what you sell appears when you have not picked your goods yet and the answer changes with them: clear for one class, a conflict for another. The result shows one line per class; pick what you sell and the check settles on one verdict.

No close matches found means nothing close turned up in USPTO records for your name or your design. It is a first screen, not a clearance: foreign filings, unregistered use and filings newer than the last data refresh are outside it.

Whatever the verdict, it is a screening signal, not a legal determination of infringement. A likelihood-of-confusion opinion under Lanham Act section 2(d) is something only a qualified trademark attorney can give.
