Appeal No. 2005-0817
Application No. 10/167,683
582 F.2d 638, 642, 199 USPQ 137, 140 (CCPA 1978). The second
prong of the test is whether the problem addressed by the prior
art is reasonably pertinent to the problem confronting the
applicant.
In the present case, we fully concur with the examiner that
Nakamura's disclosure of how to form a semiconductor layer is
reasonably pertinent to appellants' problem of forming a semi-
conductor layer in a micro- or nano-electronic device. Appellants
have failed to advance any rationale why Nakamura's process of
forming a semiconductor layer by solution coating a dispersion
would have been considered by one of ordinary skill in the art as
unsuitable for, or unrelated to, making the recited electronic
devices. We note that appellants' specification discloses the same
organic semiconductor materials as those disclosed by Nakamura,
e.g., perylene pigments, metal phthalocyanines and halogenated
anthanthrones (compare appellants' specification, at page 6, second
paragraph, to Nakamura at column 4, lines 43-53). Inasmuch as
appellants are forming semiconductor layers comprising the same
components as the semiconductor layer of Nakamura, we find that one
of ordinary skill in the art would have found it prima facie
obvious to employ Nakamura's process for forming the semiconductor
layer of the claimed devices.
