Apparatus for light, heat, cold, cooking, ventilation, water supply and sanitation — bulbs and fittings, fans, geysers, air conditioners, water purifiers, chimneys, taps and sanitaryware.
Below: the official class heading, 6 kinds of business that file here, 4 things that get filed here by mistake and where each actually belongs, the 4 classes usually filed alongside class 11, and all 45 classes in one table.
As published in the Nice Classification, the WIPO list the Indian register is organised on.
Apparatus and installations for lighting, heating, cooling, steam generating, cooking, drying, ventilating, water supply and sanitary purposes.
Transcribed from the Nice Classification (11th edition). WIPO revises these headings between editions, and a heading describes a class rather than closing the list of what falls in it — the Registry's own list of goods and services is what governs a filing.
Concrete enough to recognise yourself in, or to rule yourself out. These are our judgements, not the Registry's.
Each of these belongs in a class of its own, linked. Getting it wrong is not fatal, but it is slow and it is paid for twice.
The first cut in the whole system, and the one that decides half of all misfilings.
Classes 1 to 34 are goods — things somebody makes and somebody else owns afterwards. Classes 35 to 45 are services — things somebody does. Class 11 is on the goods side, which means a registration here covers the article you sell and not the service you perform around it. Selling it in your own shop, making it to somebody else's order, delivering it, teaching people to use it — those are separate classes on the other side of the line.
Neighbouring numbers are not neighbouring businesses. The classification was assembled over decades and its order is historical, so class 11 sits beside class 10 and class 12 for reasons that have nothing to do with what a modern company sells. Read down the table at the foot of this page rather than around a number.
The single most expensive misunderstanding in Indian trademark filing.
A trademark registration is a right in the classes named on it. Registering in class 11 gives you nothing in the other 44: the identical name remains available to somebody else in every class you did not file, and they can register it there. This is not a loophole — it is the design. The classification exists precisely so that the same word can belong to a shoe company and to a software company at once.
Read the other way it is the reassuring half. A mark already registered in a class unrelated to yours generally cannot stop you using the name in yours, which is why a search that comes back with hits is not automatically a dead end — what matters is whether the hits are in your class and near your goods. Well-known marks are the exception the system writes for itself, and whether a mark is well known is a finding the Registry makes, not something read off a list.
The practical consequence is that the classes you file describe the business you intend to be, not only the one you are. Extending into a class later means filing later — at that day's queue, and against whatever has been registered in the meantime by somebody who read this page sooner.
General information, not legal advice. This page explains how the classification system is organised. It is not advice about your filing: which class or classes a mark belongs in depends on the goods and services you actually supply, and the specification is drafted word by word, not chosen off a list. Have a trademark attorney confirm the classes and the wording before you file. We publish no filing fees anywhere on this site — they are set by the Registry and revised from time to time, and we have no verified source for them, so take them from the Registry's own schedule.
Why each one comes up. Our judgement, from the way these businesses are actually built.
| Class | Covers | Why it comes up with class 11 |
|---|---|---|
| Class 21 | Kitchenware, glassware and brushes | Kitchen and bathroom brands sell apparatus and utensils side by side, and the classification splits them. |
| Class 9 | Software, electronics and instruments | Anything with a controller, a sensor or an app is class 9 apparatus as well. |
| Class 37 | Construction, installation and repair | Installation, AMC and repair are class 37 services, and in appliances they are usually where the customer relationship lives. |
| Class 35 | Advertising, retail and business services | The showroom, dealer network and online store are class 35. |
Classes that name class 11 as their companion
Classes that sit in the same part of the classification as class 11.
A class is one queue. The address is another, and it is the one that goes on the packaging.
A registration in class 11 covers lighting, heating and sanitary apparatus on the register. It reserves no address, no handle and no listing — those are first-come queues run by people who have never heard of the Nice Classification.
A trademark class and a domain name have nothing to do with each other, and each is regularly mistaken for the other. Registering a domain creates no trademark right of any kind — the registrar sells you a rental on an address and makes no enquiry into who else uses the name. A trademark registration, equally, reserves nothing at any registry: the matching address can be bought by anyone while your application sits in the queue.
Which is why the practical order is to check both before printing anything. Across the 14 endings we price, the range runs from .xyz at ₹249 to .ai at ₹15,400. Five of them, and what each costs for a first year:
Indicative first-year prices from our own table, not a registrar quote, and not an availability answer — whether a particular name is free is a question only a live lookup can settle. Each ending has its own page with who it suits and how the check works.
Apparatus for light, heat, cold, cooking, ventilation, water supply and sanitation — bulbs and fittings, fans, geysers, air conditioners, water purifiers, chimneys, taps and sanitaryware. The Nice Classification heading for class 11 reads: Apparatus and installations for lighting, heating, cooling, steam generating, cooking, drying, ventilating, water supply and sanitary purposes.
Goods. Classes 1 to 34 cover goods and classes 35 to 45 cover services, and class 11 is the 11th of the 34 goods classes. The distinction matters more than it looks: the thing you sell and the service you perform around it are different classes even when they carry the same name, which is why a manufacturer that also runs a shop, or a studio that also sells a product, ends up on both sides of the line.
No. A registration is a right in the classes it names and nowhere else, so a mark registered in class 11 leaves the same name available to somebody else in the remaining 44. The rule read the other way is the useful half: a mark somebody else holds in a class unrelated to yours generally cannot stop you, which is how identical names co-exist across unrelated industries. Well-known marks are the exception the system carves out for itself, and whether a mark is well known is decided by the Registry rather than by the class list.
Apparatus for water supply and sanitary purposes is named in class 11, which is where purifiers sit. The chemicals used to treat water are class 1 or class 5, and the plumber who fits it is class 37.
The luminaire is class 11 and the control apparatus is class 9. A connected-lighting brand normally files both, because a competitor could otherwise take the name on the app while you hold it on the bulb.
No, and no static page can. This file was built ahead of time and serves the same bytes to everyone, while applications and registrations move daily. The register is maintained by the Office of the Controller General of Patents, Designs and Trade Marks, and its public search is free to use — this page is for working out which class to search in, which is the question that has to be answered first.

One search runs the domain endings, the social handles and the marketplace listings together, so you find out the name is gone before the specification is drafted rather than after.
