a particular area with a reasonable degree of precision and
particularity.
We give the terms of the appealed claims their ordinary
meaning unless we find that another meaning is intended by
appellants. See In re Morris, 127 F.3d 1048, 1054-55, 44
USPQ2d 1023, 1027 (Fed. Cir. 1997); In re Zletz, 893 F.2d 319,
321-22, 13 USPQ2d 1320, 1322 (Fed. Cir. 1996). Here, as
explained by appellants in their specification (page 6, lines
12-26), any of the compositions made up of the specified
components in the specified amounts have "properties which are
characteristic of a true binary azeotrope." While we are
cognizant that appellants offer a more conventional and
perhaps more limiting definition of "azeotrope" at page 9,
lines 3-7) of their specification, it is clear from the
specification as a whole that appellants use the term
"azeotropic" in their claims to embrace all of the
compositions that include the claimed specified components in
the specified amounts. In this regard, we note that the
specification makes manifest that mixtures that do "not tend
to fractionate to any great extent upon evaporation"
(specification, page 6, lines 18-20) are included within
