Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 12, 16, 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yoshimura et al., US 2013/0330617.
Regarding claim 12, Yoshimura et al., does not teach device of claim 33, wherein the conductive protection layer has a purity of 70 wt.% or more, wherein the conductive protection layer comprises a metal layer having an impurity content of 1 wt.% or less, or wherein the conductive protection layer has an oxygen content of 30 wt.% or less.
However, "[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955).
In addition, Yoshimura comprises the same materials as in the Application, such as aluminum alloy layer (0038; 0055) and conductive protection layer, such as titanium (0038; 0047), or chromium (Cr) (0047).
Thus, A prima facie case of obviousness may be made when chemical compounds have very close structural similarities and similar utilities. "An obviousness rejection based on similarity in chemical structure and function entails the motivation of one skilled in the art to make a claimed compound, in the expectation that compounds similar in structure will have similar properties." In re Payne, 606 F.2d 303, 313, 203 USPQ 245, 254 (CCPA 1979). See In re Papesch, 315 F.2d 381, 137 USPQ 43 (CCPA 1963) (discussed in more detail below) and In re Dillon, 919 F.2d 688, 16 USPQ2d 1897 (Fed. Cir. 1990).
Regarding claim 16, Yoshimura et al., teaches device of claim 15, wherein the composite structure comprises at least a first sub-layer (metal layer) (abstract) and a second sub-layer (mixed layer) (abstract; 0063-0075), and wherein the first sub-layer and the second sub-layer comprise the same material or different materials (abstract; 0063-0075).
Yoshimura does not teach each sublayer independently have a purity of 70 wt.% or more.
However, "[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955).
In addition, Yoshimura comprises the same materials as in the Application, such as aluminum alloy layer (0038; 0055) and conductive protection layer, such as titanium (0038; 0047), or chromium (Cr) (0047).
Thus, A prima facie case of obviousness may be made when chemical compounds have very close structural similarities and similar utilities. "An obviousness rejection based on similarity in chemical structure and function entails the motivation of one skilled in the art to make a claimed compound, in the expectation that compounds similar in structure will have similar properties."

See In re Papesch, 315 F.2d 381, 137 USPQ 43 (CCPA 1963) (discussed in more detail below) and In re Dillon, 919 F.2d 688, 16 USPQ2d 1897 (Fed. Cir. 1990).
Regarding claim 22, Yoshimura et al., does not teach device of claim 33, wherein the conductive protection layer has an electrical conductivity of from 105 S/m to 108 S/m or an electrical resistivity of from 10-8Q-m to 10-6Qm.
However, "[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955).
In addition, Yoshimura comprises the same materials as in the Application, such as aluminum alloy layer (0038; 0055) and conductive protection layer, such as titanium (0038; 0047), or chromium (Cr) (0047).

"An obviousness rejection based on similarity in chemical structure and function entails the motivation of one skilled in the art to make a claimed compound, in the expectation that compounds similar in structure will have similar properties."
