Trademark Class 45: Legal and personal services — What It Covers, With a Live Count
Short answer
Trademark class 45 covers legal services, security services, and personal and social services rendered to meet the needs of individuals. It is a services class, and as of September 14, 2026 it holds 43,032 live US marks, 0.9% of the register, ranking 31 of 45 by size. A registration in class 45 protects the name only for these services; the same name can be, and often is, registered by an unrelated business in another class.
Class 45 is a small class, with 43,032 live marks out of 4,796,936 across all 45 classes. A live mark is one that is registered or pending; the count is computed from USPTO bulk data by each mark's primary class and refreshed daily.
Class 45 is the class of last resort for services, which gives it an odd mix: law firms, security guards, dating services, and social networks. Social networking is 45 by USPTO convention, with the app in 9 and the platform in 42. Licensing intellectual property is 45, so a brand that licenses its name to others files here. Domain registration services are 45, which is where a domain registrar's own mark sits.
What files in class 45
| Typically in class 45 | Examples of businesses |
|---|---|
| law firms and legal services | law firms and legal tech |
| online legal document services | security companies |
| security guard and alarm monitoring services | dating apps |
| dating and matchmaking services | social networks |
| funeral services | IP licensing businesses |
| licensing of intellectual property | funeral homes |
| social networking services (online) | concierge services |
| concierge and personal assistant services | |
| domain name registration services | |
| genealogy and background check services |
The USPTO's ID Manual lists the accepted descriptions for class 45. Choosing one of them keeps the filing fee at $350 per class; a custom description costs $550. See what a trademark costs.
What is not in class 45
| Looks like class 45, but is | Class |
|---|---|
| the dating or social app itself | 9 |
| the platform as a service | 42 |
| insurance and financial services | 36 |
| business consulting | 35 |
| market research and business investigation | 35 |
The class follows the product, not the industry. A business in this field will often need one of the classes above as well as class 45; the second class is a second filing fee, and a registration in one does not cover the other.
Coordinated classes
The USPTO searches class 45 together with these classes when it examines an application, because confusion between them is common. A live mark in a coordinated class can block a class 45 application, and a class 45 mark can block one of these.
A near match in a coordinated class is worth reading closely. A near match anywhere else on the register is usually not. See is my name trademarked for how to read one.
How crowded class 45 is
| Live marks in class 45 | 43,032 |
| Share of the 45-class register | 0.9% |
| Rank by size | 31 of 45 |
| As of | September 14, 2026 |
A smaller class means fewer near matches, and a name that is clear here tends to stay clear. It is still worth searching the coordinated classes, since that is where a conflict for a class 45 mark most often comes from.
Before you file in class 45
- Confirm the services are actually class 45 against the USPTO ID Manual, not against the industry the business is in.
- Check the neighbouring classes in the table above for anything the business also sells or does.
- Search the name on Silvol and read every live match by class: class 45 and its coordinated classes matter; others usually do not.
- Budget per class. Each class is $350 to file and $650 every ten years to maintain.
