Appeal No. 2005-0622
Application 09/911,279
Held and Caiger to obtain the disclosed benefits of Savu=s
surfactant relative to the C8 fluorinated surfactants of Held and
Caiger.
Savu teaches that the disclosed surfactant is useful as a
leveling additive for various resist inks for electronics and
semiconductors, and for inks such as gravure coat, screen print,
thermal print and pen inks (page 25, lines 17-19 and 25). This
disclosure would have provided one of ordinary skill in the art
with a reasonable expectation of success in using Savu=s
surfactant in other ink compositions, such as the inkjet ink
compositions of Held and Caiger.
The appellants question why one of ordinary skill in the art
would have been motivated to substitute Savu=s surfactant for
those of Held and Caiger, given the disclosures by Held and
Caiger that their C8 surfactants are acceptable, and particularly
given the disclosure by Held of using the C6-22 fluorinated
surfactants in combination with a siloxane surfactant (brief,
pages 15-16 and 21; reply brief, page 4). The motivation would
have been to obtain the above-discussed benefits disclosed by
Savu of using Savu=s surfactant instead of a C8 surfactant.
