Trademark Registration – Classification Guide Class 4 in Japan

We have developed a biomass alcohol fuel made from soybeans that do not produce CO2. First of all, we have prepared an impactful product name and logo for the new biomass alcohol fuel, and we would like to register it as a trademark so that others will not imitate us.

Then you need to remember to designate Class 4, which includes “fuel”!
Class 4 includes many goods related to fuel! Let’s check it out.

Considering the future development of products other than biofuels, it seems to be better to designate other goods in Class 4, as well. Is it possible to designate ”cosmetics containing isoflavone” in Class 4 as well…?

Class 4 is a classification for small manual kitchen utensils, cosmetic utensils, glassware, etc.

Class 4 includes mainly solid fuels, liquid fuels, gaseous fuels, and industrial oils.

It may be easier to understand if you associate them with fuels that generate energy when burned, such as crude oil, gasoline, coal, natural gas, or biomass fuels.

Goods included in Class 4 and Goods NOT included in Class 4.

The above list of “the main goods included in Class 4” is just an example.
Let’s take a closer look at what other goods are included in Class 4 and what goods are not.

What should you do if you want to specify such items? (Goods included in Class 4)

Goods related to fuel.

I see, that even though they are made from soybeans, “cosmetics” and “sweets” are classified differently.

Right, it is necessary to designate a different classification for these “cosmetics” and “sweets”.

Other goods NOT included in Class 4.

• wicks for oil stoves【class 11】
• wicks adapted for cigarette lighters【class 34】

Even if it’s a wick for burning, it doesn’t fall under Class 4, unless it’s used for lamps!
