Why are trademark classes important?

Trademark classes, be it Trademark Class 40 or any other class, are a very important part of the Trademark registration process. Firstly, they help make the trademark registration process smooth and organized. This is especially helpful for conducting a trademark search, which is a necessary step before going for trademark registration. Additionally, it ensures that having a similar trademark in a completely different category doesn’t stop or impact someone from using a similar trademark in another category.

Why is it important to choose the correct trademark class?

Trademark registration only gives you the exclusive right to use your trademark within the class that you register it. For example, if you have a skincare brand, and you register a trademark for it in the correct class, the trademark ensures that nobody else selling a similar product or service can use a similar trademark. Choosing the correct trademark class is extremely important to ensure that your trademark is protected within your industry. Choosing the wrong trademark class while filling out your trademark application can lead to your application getting rejected or receiving a formality check failure status. But that is not all, if you register a trademark in the wrong class or you miss registering it in other relevant classes you cannot protect your trademark from your competitors; you can’t enjoy the benefits of Trademark registration in the relevant fields.
