One who produces or deals in a particular thing, or conducts a particular business, may appropriate to his exclusive use, as a trademark, any form, symbol, or name which has not been so appropriated by another, to designate the origin or ownership thereof; but he cannot exclusively appropriate any designation, or part of a designation, which relates only to the name, quality, or the description of the thing or business, or the place where the thing is produced, or the business carried out.
