Appeal No. 95-2917
Application 08/082,895
about 10,000 gauss. Appellants point out that the flux
density in the preferred embodiment is of about 6,000 gauss.
Our reviewing court states that it is not a function of
the claims to specifically exclude possible inoperative
combinations. Atlas Powder Co. v. E.I. Dupont De Nemours &
Co. 750 F2d 1569, 1576, 224 USPQ 409, 414 (Fed. Cir. 1984)
citing In re Dinh-Nguyen 492 F.2d 856, 858-59, 181 USPQ 46, 48
(CCPA 1974). We note that the Appellants' specification
teaches that the critical limit of the flux density during
writing is to be equal or less than 10,000 gauss to prevent
destabilization of the magnetic read head. The specification
further provides enabling embodiments
that would have allowed those skilled in the art to make and
use the invention. Furthermore, we note that claim 1 recites
"the flux density at said MRE during writing being equal to or
less than about 10,000 gauss, whereby destabilization of the
said MRE when writing with said write head is prevented."
Therefore, we find that Appellants have met the requirements
