In today’s fast-moving world, brand protection is more important than ever. Businesses that manufacture or sell lighting, heating, cooling, or sanitary products must understand Trademark Class 11 if they want to safeguard their brand name and grow without fear of infringement.
If you’re wondering what exactly Trademark Class 11 covers and how it affects your business, you’re in the right place.
This complete guide breaks down everything — from meaning, coverage, and examples, to registration steps, common mistakes, and expert tips.
Let’s dive in!
Introduction to Trademark Classes
Before we talk about Class 11 specifically, it’s important to understand how trademarks are categorized.
The trademark system is divided into 45 classes:
- Classes 1–34 cover goods.
- Classes 35–45 cover services.
Each class represents a specific category. When you file a trademark application, you must select the right class that matches your product or service.
Choosing the wrong class can lead to rejection, legal loopholes, and weak protection.
What is Trademark Class 11?
Trademark Class 11 mainly covers products related to:
- Lighting
- Heating
- Cooling
- Steam generation
- Water supply
- Sanitation
In simple terms, if your products manage air, water, heat, or light, they likely belong to Class 11.
Examples:
LED lights, air conditioners, microwaves, geysers, refrigerators, bathroom fittings, and water purifiers.
Businesses producing, selling, or distributing these products must register their brand name under Class 11 to get complete protection.

Yes, if their products/services are unrelated.
Example: “Apollo” can be used by both a tire company and a hospital.
