Appeal No. 2005-0581
Application No. 10/228,124
the art to incorporate proline, or other conventional ink drying
agents, in the coating composition of Miyabe. We find no
teaching in either of the applied references, and appellant has
pointed to none, that drying agents such as proline would be
unsuitable for the coating layer of Miyabe.
Appellant maintains that "Miyabe is directed to synthetic
papers, and that the reference teaches at column 2, lines 4 to
35, that coatings suitable for real papers are not necessarily
suitable for use with synthetic papers" (page 12 of principal
brief, penultimate paragraph). Appellant urges, therefore, that
claim 9, which defines the substrate as paper, is particularly
allowable. However, this argument does not speak to the
obviousness of using a known ink drying agent disclosed by
Isganitis in the coating layer of Miyabe. As stated by the
examiner, "[t]here is no teaching in Miyabe that the coating of
the reference is unsuitable for use on cellulosic paper supports"
(page 7 of Answer, first paragraph). Also, we agree with the
examiner that the broadly recited "paper" of claim 9 encompasses
synthetic paper, particularly since appellant's specification
refers to different types of materials as paper, including filled
plastics for making "never-tear paper" (page 18 of specification,
first paragraph).
