Appeal 97-2360
Application 08/234,495
A cycloalkane is a hydrocarbon having the empirical
formula C H . See, e.g., A Dictionary of Chemistry, Oxford
n 2n
University Press, page 144 (1996): "cycloalkanes Cyclic
saturated hydrocarbons containing a ring of carbon atoms
joined by single bonds. They have the general formula C H
n 2n
for example cyclohexane, C H , etc."

The compounds described by Simmonds do not have an
empirical formula which fits into the C H model. For
n 2n
example, adamantane (col. 4, line 4) has the empirical formula
C H ; pinane (col. 4, line 11) has the empirical formula C H ;10 16 10 18
camphane (col. 4, line 11) also has the empirical formula
C H ; and bicyclo[3.3.1]nonane (col. 4, line 1) has the
10 18
empirical formula C H . See the attached printouts from CD-
9 16
ROM versions of the Merck Index (version 12.1a) (page 6,
infra) and the Handbook of Chemistry and Physics (CRC Press,
Properties of Organic Compounds (1996)) (pages 7-9, infra).
The examiner has not demonstrated that any compound
listed in col. 4, lines 1-30 is a perfluorocycloalkane.
Accordingly, applicants are correct stating that Simmonds does
not describe a perfluorocycloalkane within the scope of claims
21-29.
