Application No. 08/391,379
1228 (1984); W.L. Gore and Associates, Inc. v. Garlock, Inc.,
721 F.2d 1540, 1554, 220 USPQ 303, 313 (Fed. Cir. 1983), cert.
denied, 469 U.S. 851 (1984).
The examiner has indicated how he reads these claims
on Ozawa [answer, pages 4-5]. Appellants argue that each of
these claims recites that the impedance value defines the
cassette characteristic and that Ozawa does not teach or imply
the use of impedance values to encode cassette characteristics
[brief, pages 4-7]. We note that the examiner has referred to
an IC chip connected to part 2 of Ozawa as meeting this
limitation.
We agree with appellants that Ozawa does not fully
meet the invention of these claims. Ozawa’s cassette is
designed to carry a memory chip with information that can be
bidirectionally communicated with the recording and
reproducing unit. Appellants are correct that a memory chip
is not an impedance and has no impedance value to indicate
anything. The only impedance shown in Ozawa’s Figure 3 would
be the loading detector 8 which merely detects when the
cassette has been inserted into the recording and reproducing
