If you have a successful brand, then you should strongly consider registering a trademark

Here are 3 main reasons why your business should have a registered trademark. A trademark gives you the exclusive right to use that registered mark, such as the business name, logo, or slogan, and will allow you to prevent somebody else from using that mark if they're selling the same product or service as you. Keep in mind, if another business owner is using the same business name as yours, that might be permitted as long as they're in a different class. For example, Delta Airlines can coexist with another company called Delta Faucets. One does air travel, the other one does kitchen sinks. So essentially, the main reason you want to have a trademark for your business is so that a competitor doesn't come along and essentially copy your business and sell the same product or service and basically piggyback off the success of your brand. If someone is doing this to you and you don't have a trademark, then there's basically nothing you can do. But if you have a trademark, then you can send them a cease and desist letter or even take them to court. So if you're serious about building a business or brand, then you should definitely register a trademark. And if that's something you're interested in doing, then let me know.
