Rule 19 - Name or Other Identification Required To Appear on Labels.

(a) The name required by the Act to be used on labels shall be the name under which the person is doing business. Where a person has a word trademark, used as a house mark, registered in the United States Patent Office, such word trademark may be used on labels in lieu of the name otherwise required, provided the owner of such word trademark furnishes the Commission a copy of the registration prior to its use. No trademark, trade names, or other names except those provided for above shall be used for required information purposes.

(b) Registered identification numbers, as provided for in Rule 20, may be used for identification purposes in lieu of the required name. [16 CFR 303.19]
