No certificate of authority shall be issued to a foreign corporation if the name of that foreign corporation would be prohibited to a corporation under the provisions of chapter 302A. The name of that corporation may contain the word "cooperative" if it is a cooperative corporation generally similar to the kind which may be organized under the laws of this state. If that corporation is a corporation obtaining a certificate of authority pursuant to the provisions of section 303.04, the name of that corporation may contain the words "bank," "trust," "building and loan," or "savings" and such corporation shall not be required to add the word "incorporated" or the abbreviation "Inc." to its corporate name. If its real name is unavailable, a foreign corporation may use an alternate name to transact business in this state if it delivers to the secretary of state a certified copy of the resolution of its board of directors adopting the alternate name. The alternate name must meet the requirements of section 302A.115, and need not be filed under sections 333.001 to 333.06.
Nothing in this section shall abrogate or limit the law as to unfair competition or unfair practices nor derogate from the common law, the principles of equity, the statutes of this state or of the United States with respect to the right to acquire and protect trade names.
If a foreign corporation does business in this state under a name prohibited by this section, the courts of this state having equity jurisdiction may, upon the application of the state or of any person, unincorporated association, or corporation interested or affected, enjoin such foreign corporation from doing business in this state under such name, whether or not a certificate of authority shall have been issued to such foreign corporation.
