(emphasis added). 35 U.S.C. § 103(a)(1999); Graham v. John Deere
Co., 383 U.S. 1, 14, 148 USPQ 459, 465 (1966).
Here, as pointed out by the appellants in their briefs, the
examiner has not established any convincing reason, suggestion or
motivation for combining the references so as to arrive at the
claimed subject matter. In particular, the examiner has not
fairly explained why one of ordinary skill in the art would turn
to the disparate structure of Watanabe, and teachings related
thereto, for a suggestion to modify the structure of Oda.
Watanabe is concerned with furnishing a temperature controller
and related structure that is “capable of highly accurately and
quickly controlling the temperature of a semiconductor device
such as a semiconductor laser.” See column 1, lines 50-55 of
Watanabe. The temperature control system of Watanabe includes
thermal insulation (5, Fig. 1) disposed around the semiconductor
device, a temperature sensor (3, Fig. 1), an electronic cooling
device (4, Fig. 1), and a block shaped heat sink (7, Fig. 1).
Watanabe specifies that the heat sink and the electronic cooling
device function together to control temperature. Oda, on the
other hand, is concerned with an ink tank, ink jet cartridge and
recording apparatus. A head tip (18, Fig. 1) of Oda includes a
plurality of ink jet nozzles and is supported in a heat sink (17,
