Ind. Code § 24-2-1-3
A mark by which the goods or services of an applicant may be distinguished from other goods or services may not be registered if the mark:

This subdivision does not prevent the registration of a mark that is used in Indiana by the applicant and has become distinctive of the applicant's goods or services. The secretary may accept proof of continuous use of a mark by the applicant in Indiana for the five (5) years immediately preceding the date on which the claim of distinctiveness is made as evidence that the mark has become distinctive, as used on or in connection with the applicant's goods or services; or
(6) is a mark that so resembles a mark registered in Indiana or a mark or trade name previously used by another person in Indiana and not abandoned, as to be likely, if used on or in connection with the goods or services of the applicant, to cause deception, confusion, or mistake.
