Classification of goods and services.
Section 6
SEC. 6. Classification of goods and services.—The Director shall establish a classification of goods and services, for the convenience of the Patent Office administration, but not to limit or extend the applicant's rights. The applicant may register his mark or trade-name in one application for any or all of the goods or services included in one class, upon or in connection with which he is actually using the mark or trade-name. The Director may issue a single certificate for one mark or trade-name registered in a plurality of classes upon payment of a fee equaling the sum of the fees for each registration in each class.
