The term 'useful arts' does not refer to creative works and is in fact an antonym for endeavors like performing or fine art. I believe any protections of this sort actually flow from the interpretation of 'authors' and 'writings'. Article I is not intended to 'promote the arts' in the way any modern person would interpret the statement.
