If any brand conflicts with another person's registered brand, the person using the registered brand may file a written statement with the board showing the brand which conflicts with his registered brand. The board shall notify the person accused of using such conflicting brand, by certified or registered mail. The person upon whom such notification is served may appear in person before the board or present a statement to the board explaining how the unrecorded brand is not an infringement upon or in conflict with the registered brand. If the board decides that the unrecorded or last registered brand conflicts with the first registered brand, a notice shall be served upon the person using the unrecorded or last recorded brand to discontinue its use within thirty days from the receipt of such notice. Any person failing to comply with the provisions of this section is liable for all damages resulting from such failure and is guilty of a Class 1 misdemeanor.
