his specification. Thus, the examiner used impermissible
hindsight when rejecting the claims. See W.L. Gore &
Associates v. Garlock, Inc., 721 F.2d 1540, 1553, 220 USPQ
303, 312-13 (Fed. Cir. 1983), cert. denied, 469 U.S. 851
(1984); In re Rothermel, 276 F.2d 393, 396, 125 USPQ 328, 331
(CCPA 1960). Accordingly, we reverse the rejection over
Rausing in view of Taillie and either Schoder or Suzuki.
Rejection over Rausing in view of Taillie and Imperial
Imperial discloses an ion deposition printing method
wherein toner particles are attracted to a pattern of ions on
a drum and then are cold fused to a substrate using a cold
roll rather than using thermal fusion as in xerography (col.
1, lines 7-16; col. 2, lines 36-43). The toner particles in
Imperial’s method are held on the substrate by a polymeric
latex having a suitable solubility with the binder of the
toner (col. 1, line 59 - col. 2, line 2).
The examiner argues that it would have been obvious to
one of ordinary skill in the art to use Imperial’s polymeric
latex to hold Taillie’s adhesive particles in place (answer,
page 6).
