Appeal 2007-0973
Application 10/254,835
INTRODUCTION
The claims are directed to a radio guidance antenna in which the sum
of mutual inductances of antennae is minimized, and a data communications
method and a non-contact data communication apparatus which make use of
the radio guidance antenna. (Abstract.) Claim 1 is illustrative:
1. A radio guidance antenna comprising:
first and second antennas,
wherein
the first antenna has at least two regions for generating lines of
magnetic flux in reciprocal directions, and the second antenna
has first (S1) and second (S2) mutual inductances for
generating induced electromotive forces in opposite directions
due to electromagnetic induction from the first antenna,
the second antenna being arranged so that the sum of mutual
inductances between it and the first antenna is minimized.
The Examiner relies on the following prior art reference to show
unpatentability:
Bowers US 5,602,556 Feb. 11, 1997
The rejection as presented by the Examiner is as follows:
1. Claims 1-28 are rejected under 35 U.S.C. § 103(a) as unpatentable
over Bowers.
OPINION
Section 103 rejection over Bowers
Appellants submit (Br. 9) there is no teaching or suggestion in Bowers
regarding minimizing the sum of mutual inductances of the antennae as
recited in representative claim 1. Appellants argue that in Figure 4 of
