If I incorporate, will doing so prevent others from using my company name?

Incorporating will not keep another business from using your name. Generally, every business must protect its own business name and the good will that it has acquired from the sale of its goods or services in a specific geographic area. Filing articles of incorporation only prevents the secretary of state from filing a document to create another corporation, limited liability company or limited partnership that has the same, a deceptively similar, or similar name as the entity already in existence.

Can I protect a trade name nationwide?

There is no national registration of trade names. Generally, businesses, including corporations, protect their trade names by registering their trade name as a service mark or trademark if the trade name also functions as a service mark or trademark. Because of the legal complexities involved, we recommend that businesses obtain private counsel to get advice on how to protect a trade name in interstate commerce.
