Filing in Class 37
Covers the contracting/repair service itself, distinct from Class 19's building materials — a contractor and a lumber supplier with similar names are searched and cleared in different classes, which is why a name check should always cover both if the business touches construction in any form.
The USPTO charges a base application fee of $350 per class under the current fee schedule (as verified on 2026-07-07) — Class 37 is billed the same as every other class. Standard base fee under the 2025 fee schedule, filed via the USPTO Trademark Center. To keep that base fee, use pre-approved wording from the USPTO’s ID Manual to describe your services rather than a custom description, which triggers a surcharge. See the full USPTO fee schedule for current figures.
In practice, businesses filing in Class 37 often also need Class 19 (Building materials) and Class 6 (Common metals) — run a search across all of them before filing, not just this one.
