See the Answer at page 4, first full paragraph. At page 7 of
the Answer in his "Response to argument" section of the
answer, the examiner further acknowledges that "while
Defendini shows the use of glass as transparent substrate,
however, it is well known in the art that other materials such
as plastic which is polymeric material; glass; ceramics are
used as transparent materials for the substrate. . . . "
Accordingly, the examiner argues that it would have been
obvious to one of ordinary skill in the art to modify the
method of Defendini by replacing glass with the plastic
material of the "secondary references" since glass and plastic
are well known transparent materials for the substrates in the
manufacture of electrochromic devices. With respect to the
claimed requirement of depositing an organic polymer primer
coating on a surface of each of two organic polymer
substrates, the examiner contends that it would have been
obvious to one of ordinary skill in the art to further modify
the Defendini process by incorporating the step of depositing
the primer of Rukavina since the adhesion property of the
coated substrate is known to be enhanced by the primer layer
between the substrate and the metal oxide layer. See the
