Trademark is an essential part of any business or brand. It protects the intellectual property from infringements and increases the overall goodwill of the business. There are different classes under which a trademark can be registered. Some trademarks can be registered under multiple classes while some can only be registered under a single class.

It can be tricky when deciding which class your product falls under. The material used to make your product might come under a specific class but it is possible that the finished good falls under a different class. This is why it is important to understand the classes to make sure the application you file is accurate and is not rejected.

Most popular trademark classes sometimes are also the most common ones.
