What is a trade mark or a service mark?
A trade mark can be a logo, shape, or other identifying mark for a product. You can also have a similar mark for services you provide (which is called a service mark). For example, everyone has seen the swoosh symbol for Nike and the blue and white propeller emblem for BMW. Those are trademarks. As with the assumed name, if you don’t use it you don’t have the trademark. For even more protection, you can file a trademark with the United States Patent and Trademark Office. If you have a trademark or service mark others cannot use it without your express permission.
