I am starting a new business and I want to protect the name of my business
Depends on what kind of protection you want to obtain and if the name does not already beling to someone else. Generally, you can incorporate or form an LLC if the name of the company is not already in use. You can also sometimes file a trademark if the name is connected to a product or service and is subject to trademark protect. Copyright generally involves written text, not only a name. If you are concerned about some protection issue you should contact a local attorney to assist with this matter.
