Trademark Class 11: Appliances, lighting and HVAC — What It Covers, With a Live Count
Short answer
Trademark class 11 covers apparatus for lighting, heating, cooking, refrigerating, drying, ventilating, water supply, and sanitary purposes. It is a goods class, and as of September 14, 2026 it holds 131,133 live US marks, 2.7% of the register, ranking 12 of 45 by size. A registration in class 11 protects the name only for these goods; the same name can be, and often is, registered by an unrelated business in another class.
Class 11 is a large class, with 131,133 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.
Anything that heats, cools, lights, or moves water is class 11. Anything that washes or processes is class 7. An electric coffee maker is 11; a manual French press is 21; a coffee grinder is 7. Smart lighting is 11 for the bulb and 9 for the app that controls it.
What files in class 11
| Typically in class 11 | Examples of businesses |
|---|---|
| lamps and lighting fixtures | lighting brands |
| ovens, stoves, and microwaves | appliance manufacturers |
| refrigerators and freezers | HVAC equipment makers |
| air conditioners, fans, and heaters | plumbing fixture companies |
| water heaters and filters | |
| toilets, sinks, and faucets | |
| hair dryers | |
| coffee machines (electric) | |
| LED bulbs |
The USPTO's ID Manual lists the accepted descriptions for class 11. 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 11
| Looks like class 11, but is | Class |
|---|---|
| washing machines and dishwashers | 7 |
| smart-home hubs and lighting control apps | 9 |
| plumbing and HVAC installation services | 37 |
| kitchen utensils | 21 |
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 11; the second class is a second filing fee, and a registration in one does not cover the other.
Coordinated classes
The USPTO searches class 11 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 11 application, and a class 11 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 11 is
| Live marks in class 11 | 131,133 |
| Share of the 45-class register | 2.7% |
| Rank by size | 12 of 45 |
| As of | September 14, 2026 |
A crowded class means more near matches to read through, and a higher chance that one of them is in your actual field. It is still worth searching the coordinated classes, since that is where a conflict for a class 11 mark most often comes from.
Before you file in class 11
- Confirm the goods are actually class 11 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 11 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.
