In our day to day as industrial property attorneys, what is the difference between trade name, corporate name and registered trademark is a question that arises frequently.
Considering each term independently we find that a trade name is a title that grants the exclusive right of using any sign or designation as a company identifier in commercial dealings. Trade names are industrial property titles.
Trade names are independent from the names of companies which are registered in the mercantile registry as a corporate name.
The corporate name is therefore the name and signature by whom a commercial company is known collectively, limited or anonymously. It is the legal attribute contained in the deed or constitution document that allows a corporation to identify and demonstrate their legal constitution and to invoice, pay taxes, etc.
However, a registered trademark is any sign capable of being represented graphically which distinguishes in the market goods and / or services from the others exclusively. The owner of this industrial property right which grant exclusive use may be a natural or legal person whose name does not have to match the name appearing on the trademark register.
