Welcome back to our USPTO Trademark Classes Blog Series, where we guide businesses through the trademark classification system to help them protect their brands effectively.
In this installment, we’re covering Trademark Class 11, which includes environmental control apparatus such as heating, cooling, lighting, cooking, and sanitation equipment. If your business manufactures or sells products related to climate control, appliances, or air and water treatment, this class may be the right fit for your trademark.
If you’ve ever asked, “Can I trademark my lighting or HVAC product?” or “Does my appliance brand fall under Class 11?”, this guide will help clarify whether this classification is the best option for your brand.
What is Trademark Class 11?
Trademark Class 11 covers appliances and devices related to heating, cooling, lighting, sanitation, and fluid regulation. These products are commonly used in residential, commercial, and industrial settings.
Some examples of goods that might fall under Trademark Class 11 include:
Lighting Fixtures: Lamps, LED lights, chandeliers, spotlights
HVAC Systems: Air conditioners, heaters, ventilation units, thermostats
Cooking and Kitchen Appliances: Ovens, stoves, toasters, coffee machines
Water and Air Treatment Devices: Water filters, air purifiers, humidifiers, dehumidifiers
Refrigeration Equipment: Refrigerators, freezers, ice makers
Sanitary Installations: Toilets, sinks, showers, bidets
Fire Protection Equipment: Fire sprinklers, extinguishers, smoke detectors
If your product controls temperature, air, water, or lighting, Trademark Class 11 may be the correct classification.
Why Trademark Class 11 Matters for Your Business
Registering a trademark under Class 11 helps protect brands within the appliance, lighting, HVAC, and sanitation industries. Here’s why filing in this class might be important:
Exclusive Brand Rights
Trademark protection ensures competitors cannot use a similar name or logo in the same industry, preventing brand confusion.
Market Differentiation
The home appliance and environmental control sectors are highly competitive, and a trademark helps establish brand trust and recognition.
Protection Against Counterfeiting
Many HVAC and lighting products are subject to counterfeiting. A trademark can help you enforce your rights and take legal action if necessary.
Business Growth and Expansion
If you plan to expand your brand into related product categories, a trademark in Class 11 could strengthen your brand’s legal protection in multiple areas.
Examples of Trademarks in Class 11
Many well-known appliance and HVAC brands have trademarks registered under Class 11. Here are a few examples:
GE Appliances® – Trademarks for refrigerators, ovens, dishwashers, and washing machines.
Dyson® – Protects its air purifiers, hand dryers, and vacuum-related products.
Honeywell® – Trademarks for thermostats, humidifiers, and air conditioning systems.
These companies rely on trademark protection to maintain their brand identity in highly competitive markets.
Do You Need a Trademark Search Before Filing in Class 11?
A comprehensive trademark search is highly recommended before applying in Class 11. Appliance and lighting brands often have overlapping names, making potential conflicts more common in this category.
At Brand Diplomacy, we conduct thorough trademark searches to ensure your brand has the best chance of approval. Here’s how we help:

How to Determine if Class 11 is Right for Your Trademark
If you’re unsure whether Trademark Class 11 is the correct category for your product, consider the following:
Does Your Product Control Air, Water, Light, or Temperature?
If your device regulates an environment, such as an air conditioner, heater, or humidifier, Class 11 is likely appropriate.
Is Your Product a Household or Industrial Appliance?
Home appliances (stoves, fridges, ovens) and industrial lighting or cooling systems typically belong in Class 11.
Does Your Product Overlap with Other Classes?
Some environmental control products may require multiple classifications. Examples include:
Smart thermostats could also require Class 9 (Scientific & Electronic Devices).
Commercial cooking appliances might fall under Class 7 (Machinery & Industrial Equipment).
Medical air purifiers could need Class 10 (Medical Devices).
If your product crosses multiple categories, filing in more than one class might be necessary for complete protection.
