Interference No. 104,158 this art to attach a cartridge to a razor handle. In our view, it would have been obvious to use guide rails in the apparatus of Althaus’ claim 1 taken as prior art. Thus, we reverse the decision of the APJ, and we will redeclare the interference with claim 9 of the Althaus patent designated as corresponding to the count. Inasmuch as guide rails are an obvious inclusion, based on the teachings found in Kirk, Terry and Ishida, on the device disclosed in the Oldroyd PCT document, which is prior art to Althaus, we hereby further conclude that the subject matter of claim 9, newly reinstated in the interference, is unpatentable over the prior art. Accordingly, judgment as to claim 9 based on unpatentablity over the prior art will be entered against Althaus, hereinbelow.
