Official class heading, Nice Classification 12th edition
Apparatus and installations for lighting, heating, cooling, steam generating, cooking, drying, ventilating, water supply and sanitary purposes.
Often filed in class 11 by mistake
Filing in the wrong class leaves your real products unprotected and still costs the class fee. These belong elsewhere.
Typical conflicts for class 11 marks
Appliance marks often meet kitchen machines in class 7, housewares in class 21 and smart home electronics in class 9.
An office compares your mark with earlier marks for identical and related goods or services, not only within the same class. Run a trademark availability search to see the closest marks in class 11 and its neighbours, or order a clearance search before a launch.
