and 10 merely broadly claim using these concepts in a combined
radio telephone system. We agree with the examiner that the
broad recitation of these conventional features in the radio

We now consider the rejection of claims 13-18, 20-22, 24-
29, 32-34, 36-40 and 43-45 based on the teachings of Schellinger
and D’Amico. The examiner has indicated how he finds the
invention of these claims to be obvious over the collective
teachings of Schellinger and D’Amico [answer, pages 8-11]. The
examiner cites Schellinger as teaching a radio telephone which
can communicate with either a cordless base station or a cellular
base station. The examiner essentially finds that Schellinger
teaches the claimed invention except that Schellinger does not
