Filing in Class 45
A genuinely wide-ranging catch-all class — dating apps, background-check services, security guard firms and law practices all register here, grouped as "personal and legal services" rather than by any shared function. Legal and IP-services firms should expect a more crowded field than the class's narrow name suggests.
The USPTO charges a base application fee of $350 per class under the current fee schedule (as verified on 2026-07-07) — Class 45 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 45 often also need Class 42 (Software (SaaS) & tech) and Class 35 (Advertising & retail) — run a search across all of them before filing, not just this one.
