the percent of binder (absent any optional elements) would be
50 to 99.75 or preferably 75 to 97.5 percent. Thus, the
claimed range of at least 75 percent could be considered to be
disclosed. However, claims 28 and 30 recite a range of at
least about 97 percent, which does not correspond with either
calculated range. Similarly, for the second coating layer,
the microspheres are present in an amount of 0.1 to 10 percent
or preferably 0.1 to 3 percent. Calculating the percent of
binder yields 90 to 99.9
percent or preferably 97 to 99.9 percent. Yet the claimed
percentage is at least about 75 percent in all four claims.
Since at least 75 percent does not even remotely correspond to
the calculated ranges, we have to agree that the claimed
ranges are not supported by the original disclosure.
With respect to the obviousness rejections, independent
claim 1 requires a recording sheet
which consists essentially of . . . (2)a first
coating layer which comprises a binder and
microspheres having an average particle diameter of
at least about 1 micron;(3)a second, ink-receiving
coating layer . . . comprising a hydrophilic binder
and microspheres having an average particle diameter
of at least about 1 micron. (emphasis added)
