Appeal No. 98-1239 Application No. 08/742,372 directed to a spring hanger assembly for supporting a portion of a pipe, line, would have commended itself to the attention of one of ordinary skill in the art of flexible couplings, we cannot agree that there is any suggestion to combine the teachings of Louette and Davidson in the manner proposed. The mere fact that the addition of a circumferential groove to the joint of Louette would prevent Louette's metal retainer from coming off, and thus result in a safer assembly, does not serve as a proper motivation to combine the teachings of Louette and Davidson as the examiner apparently believes.
