How do I register my company name?
However, before you register your company name, you want to determine if your company name is already in use in your state. Your state will generally not let you use a name that is too similar to an already registered business. For this reason, whenever you consider registering your company name as a trademark, you want to research your state's database for registered corporations, LLCs and partnerships with similar names.
LegalZoom's U.S. Comprehensive Trademark Search can help you find these conflicts before starting a trademark application.
