A class 30 trademark is something I recently discovered and it's pretty interesting. It primarily refers to trademarks related to foodstuffs and beverages that aren't included in other categories. These could be things like coffee, rice, bread, or even pastries. It's an essential part of protecting your brand, especially if you're in the food industry. So, if you're planning to trademark a unique food or beverage product, you might be dealing with a class 30 trademark.
