Trademark Classes · Class 11
Class 11 covers apparatus for lighting, heating, cooking, refrigeration, ventilation, water supply, and sanitary purposes. Here is what it includes, what it excludes, and how to word it.
Class 11 is a goods class covering apparatus and installations for lighting, heating, cooling, steam generating, cooking, refrigerating, drying, ventilating, water supply, and sanitary purposes. It includes lamps and lighting, heaters and boilers, cookers and ovens, refrigerators, air-conditioning, and bathroom and sanitary fittings.
The theme is environmental and utility apparatus, the fixed and appliance-type equipment that lights, heats, cools, cooks, or supplies water. Small hand-operated kitchen utensils, by contrast, are Class 21. This page is part of our full guide to all 45 trademark classes, and to how protection works across jurisdictions in our overview of trademark law and protection.
Work out whether your product or service genuinely sits in Class 11 before you file, because a wrong class protects the wrong thing.
Manufacturers of lighting and lamps, heating and cooling appliances, cookers and ovens, refrigeration and air-conditioning equipment, water-supply and purification apparatus, and bathroom and sanitary fittings. If your product lights, heats, cools, cooks, or supplies water, Class 11 is very likely your class. Our trademark class search helps you check which classes fit before you file.
The most common Class 11 mistakes come from classifying by the wrong feature. These closely related items sit elsewhere:
Non-electric kitchen utensils and containers are Class 21. Class 11 is for cooking and heating apparatus.
Industrial machinery is Class 7; environmental and utility appliances are Class 11.
The Registry expects specific, standardised descriptions, not vague terms. Here are examples of clear, acceptable Class 11 wording:
| Instead of (vague) | Use (standardised) |
|---|---|
| “Lights” | “Lamps” · “Lighting apparatus and installations” |
| “Heater” | “Heating apparatus” · “Heating installations” |
| “AC” | “Air-conditioning apparatus” · “Air-conditioning installations” |
| “Bathroom fittings” | “Sanitary apparatus and installations” · “Taps” |
Each entry is specific and standardised. These are illustrative examples of acceptable phrasing, not legal advice for your filing; your exact wording should be drawn from the current NICE Classification and tailored to what your business actually does. Wording is a common cause of objections whether you file in India, the United States, Argentina, or elsewhere. For filing across several countries at once, see our global registration guide.
Class 11 covers apparatus and installations for lighting, heating, cooling, cooking, refrigerating, drying, ventilating, water supply, and sanitary purposes. It includes lamps and lighting, heaters and boilers, cookers and ovens, refrigerators, air-conditioning, and bathroom and sanitary fittings. The theme is environmental and utility apparatus, as distinct from small hand-operated kitchen utensils, which are Class 21.
Manufacturers of lighting and lamps, heating and cooling appliances, cookers and ovens, refrigeration and air-conditioning equipment, water-supply apparatus, and bathroom and sanitary fittings. If your product lights, heats, cools, cooks, or supplies water, Class 11 is likely your class.
Class 11 covers cooking, heating, and lighting apparatus, powered appliances and installations such as ovens, heaters, and lamps. Class 21 covers small, non-electric kitchen and household utensils and containers, such as pots, pans, and glassware. A cooker is Class 11, but a saucepan is Class 21. The distinction is between apparatus and hand utensils.
Yes. Sanitary apparatus and installations, including taps, basins, and bathroom fittings, are classified in Class 11, alongside water-supply and heating apparatus. This is because the class groups apparatus for water supply and sanitary purposes together with lighting, heating, and cooking equipment.
Use specific, standardised terms such as lighting apparatus and installations, heating apparatus, air-conditioning apparatus, or sanitary installations, rather than vague words like lights or fittings. Draw wording from the current NICE Classification and tailor it to your products to reduce objection risk.
