Appeal No. 95-1798
Application 07/397,415
“incomplete” for failing to recite various process
parameters. We shall not affirm this rejection.
It is by now well established that it is the
function of the descriptive portion of the
specification and not that of the claims to set forth
operable proportions and similar process parameters and
that claims are not rendered indefinite by the absence
of the recitation of such limitations. [Citations
omitted.]
With respect to the non-prior art rejection in this appeal,
Jackson is dispositive. We therefore reverse the rejection of
claims 5 through 7, 10 and 11 under 35 U.S.C. § 112, second
paragraph.
SECTION 103
Claims 2 through 4, 12 and 14 through 18 stand rejected
under 35 U.S.C. § 103 as unpatentable over the combined
disclosures of DeBoer and Bertoni. According to the examiner, it
would have been obvious to modify DeBoer’s iodinated contrast
agent for radiography, per the teachings of Bertoni, to arrive at
the claimed subject matter. We disagree.
Independent claim 14 defines a water-soluble iodinated
polymer comprising a dextran backbone having grafted thereon
groups of the formula
