Appeal No. 1998-1146 Page 8
Application No. 08/410,177
The examiner (answer, pages 4 and 5) has found that
Comelli exemplifies the use of a mixture of 1,3-dioxolane with
3-methylpentane in determining thermodynamic properties of
such mixtures. As found by the examiner, the fifth
composition reported in the third column of Table II of
Comelli "exemplifies having a molar ratio of 0.3182 moles of
1,3-dioxolane and 0.6818 moles of 3-methylpentane" which
corresponds to "a weight ratio of about 29 weight percent 1,3-
dioxolane and about 71 weight percent 3-methylpentane" (answer
pages 5 and 6). Appellants’ representative claim 1 is
inclusive of such a composition by calling for from about 4 to
about 50% by weight of 1,3-dioxolane and from about 59 to
about 77% by weight of 3-methylpentane as one optional
azeotropic mixture. As such, we agree with the examiner that
Comelli anticipates, prima facie, the composition required by
representative claim 1 as well as claims 2, 5 and 9 which
latter claims stand or fall together with representative claim
1. Similarly, we agree with the examiner that Inglese
anticipates, prima facie, the composition required by
representative claim 1 as well as claim 2 for reasons as et
forth by the examiner at page 7 of the answer.
