(5) consists of a mark which, (i) when applied to the goods or used to identify the services of the applicant, is merely descriptive or deceptively misdescriptive of them, or (ii) when applied to the goods or used to identify the services of the applicant is primarily geographically descriptive or deceptively misdescriptive of them, or (iii) is primarily merely a surname provided, however, that nothing in this clause (5) shall prevent the registration of a mark used in this state by the applicant which has become distinctive of the applicant's goods or services. The secretary of state may accept as evidence that the mark has become distinctive, as applied to the applicant's goods or used to identify the services, proof of substantially exclusive and continuous use as a mark by the applicant in this state for the five years next preceding the date of the filing of the application for registration; or

The secretary of state may require the applicant to obtain affidavits by both the applicant and by the holder of the previously registered name or mark in making this determination.
