Classification.

(1) The department shall use the international schedule of classes of goods and services as set forth in 37 C.F.R. s. 6.1, as amended, as the state classification system for trademarks.

(2) The establishment of the classes of goods and services set forth in subsection (1) is not for the purpose of limiting or extending the rights of the applicant or registrant. A single application for registration of a mark may include any or all goods upon which, or services with which, the mark is actually being used comprised in one or more of the classes listed, but in the event that a single application includes goods or services in connection with which the mark is being used which fall within different classes of goods or services, a fee equaling the sum of the fees for registration in each class shall be payable.
