Appeal No. 1998-0189
Application 08/196,933
(1) Claims 1 through 4, 7, 10, 13, 41, and 42 are rejected under 35 U.S.C.
§ 103(a) as unpatentable over JP’2795 (see PTO English-language translation for
cites).
The following findings of fact are supported by a preponderance of the evidence.
10. JP’279 describes an ink jet recording medium that is capable of recording
images using a water-based ink containing a water-soluble dye. The recording medium
is said to have excellent absorption characteristics so that the printed images can be
well preserved. Translation, page 1, lines 4-5, and 15-19.
11. The recording medium of JP’279 comprises a support having thereon an ink-
receiving layer. The layer comprises a mercapto-containing nitrogen-containing-hetero-
ring compound of formula (I). Translation, page 6, lines 12-23, and page 7, line 16,
through page 8, line 5. JP’279 lists eleven compounds as examples of said hetero-ring
compounds, including 5-mercapto-1-methyl tetrazole, 2-mercapto-pyrimidine, and 2-
mercapto-4-methyl-pyrimidine. Translation, page 7, lines 1-6.
12. The recited “pyrimidine” compound in claim 1 reads on the pyrimidine
compounds named in finding 11.
5The Patent Abstract of Japan JP’279 was cited as an “X” reference in the
European Search Report that was filed in the Information Disclosure Statement (IDS)
filed Jul. 14, 1997, attached to Paper No. 24. The IDS was filed before the mailing of
the examiner’s answer. According to the European Patent Office, an “X” reference is
considered to be “particularly relevant, if taken alone,” to the claimed subject matter.
