Appeal No. 1997-3302
Application No. 08/152,338
complementary electrochromic material is deposited. At this
point in the claimed process, the organic polymer substrates
are assembled in spaced relationship with the electrochromic
and complementary electrochromic films in a facing
relationship and a preformed sheet of ion-conducting polymer
is disposed between and in contact with the electrochromic and
complementary electrochromic films. The last step of the
claimed process requires the application of heat and pressure
to laminate the preformed
ion-conducting polymer sheet to the electrochromic films.
As evidence that the herein claimed process would have
been obvious to a person of ordinary skill in the art, the
examiner principally relies upon the disclosures of Defendini
and Rukavina. Referring to the disclosures in Defendini as
the "prior art," the examiner contends that the difference
between the claimed process and the "prior art" is that the
"prior art" does not show the deposition of a primer layer
between the transparent substrate and the electroconductive
metal oxide layer. The examiner further contends that it is
not clear whether the instant "preformed" ion-conductive layer
is obvious over the prior art ion-conductive polymer layer.
