Trademark
A trademark can protect the name of your business, goods, and services at a national level. Trademarks prevent others in the same (or similar) industry in the U.S. from using your trademarked names.
Businesses in every state are subject to trademark infringement lawsuits, which can prove costly. That’s why you should check your prospective business, product, and service names against the official trademark database, maintained by the United States Patent and Trademark Office.
