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.
Claims 4, 16, and 20 are rejected under 35 U.S.C. 103 as being unpatentable Kim.
Regarding claim 4, while Kim does not explicitly teach that the anti-oxidation layer (171) has a thickness of 50 Å to 100 Å, it would have been obvious to one of ordinary skill in the art to adjust and obtain the optimal thickness for the anti-oxidation layer, including the claimed thickness of 50 Å to 100 Å, as a routine experimentation. It has held that discovering an optimum or workable ranges involves only routine skill in the art. Where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the workable ranges by routine experimentation. In re Aller, 105 USPQ 233.
Regarding claim 16, Kim teaches that the anti-oxidation layer formed of a transparent conductive oxide (171 formed of ITO) (page 18). While Kim does not explicitly teach that the anti-oxidation layer is formed by a physical vapor deposition (PVD) process, it would have been obvious to one of ordinary skill in the art to deposit a desired layer by the readily available PVD process in the semiconductor fabrication for obtaining the predictable coating/deposition characteristics.
Regarding claim 20, Kim does not explicitly teach further comprising a color filter, a color conversion layer, a touch screen layer, a polarizing layer, or any combination thereof. Nevertheless, it would have been obvious to one of ordinary skill in the art to include at least one of the color filter, the color conversion layer, the touch screen layer, and the polarizing layer in combination with the light-emitting device for desired usage of the light-emitting device such as the color filter formed on the light-emitting device in order to provide desired light emitting output.
Response to Arguments
Applicant’s arguments with respect to amended claims have been considered but are moot in view of new ground of rejection as set forth above in this Office Action.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
