Hello, whether the Class 11 trademark can be used for range hoods depends on the specific goods you register. If the following goods are registered in the 1106 group of Class 11, I think it is OK. Making a range hood:

1 Kitchen range hood, if you apply for this product, you can be sure that it can be made into a range hood.

2 Air filtration equipment, with this product application, the function of the range hood is air filtration, so the range hood is indirectly included.

3 Air purification devices and machines are the same as above. With this product application, the function of the range hood is also air purification, so the range hood is indirectly included.
