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, 11 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Lairson et al. (US20100086775).
Regarding claim 4, Lairson discloses the invention as described in Claim 1, but is silent on wherein the second layer comprising silver has thickness in a range of 26 nm to 28 nm (Lairson, fig.13, Ag has thickness 30 nm).
However, Lairson teaches in paragraph [0045], thickness of the silver layer 120 may be between 5 nm and 100 nm---thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to optimize silver has thickness to fit into the claimed in a range of 26 nm to 28 nm, in order to provide a high efficiency, low-cost reflective coating for the reflective surfaces employed therein (see e.g. paragraphs [0008]), and since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art, In re Aller, 105 USPQ 233 (C.C.P.A. 1955).).
Regarding claim 11, Lairson discloses the invention as described in Claim 9, but is silent on wherein the barrier layer has a thickness in a range of 4 nm to 10 nm (fig.13, the barrier layer has a thickness 2nm).
However, Lairson teaches in paragraph [0045] the barrier layer 130 may have a thickness of less than 30 nm---thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to optimize barrier layer has thickness to fit into the claimed in a range of 4 nm to 10 nm, in order to provide a high efficiency, low-cost reflective coating for the reflective surfaces employed therein (see e.g. paragraphs [0008]), and since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art, In re Aller, 105 USPQ 233 (C.C.P.A. 1955).).
Regarding claim 15, Lairson discloses the invention as described in Claim 14, but is silent on wherein the silver layer has thickness in a range of 26 nm to 28 nm (Lairson, fig.13, Ag has thickness 30 nm).
However, Lairson teaches in paragraph [0045], thickness of the silver layer 120 may be between 5 nm and 100 nm---thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to optimize silver has thickness to fit into the claimed in a range of 26 nm to 28 nm, in order to provide a high efficiency, low-cost reflective coating for the reflective surfaces employed therein (see e.g. paragraphs [0008]), and since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art, In re Aller, 105 USPQ 233 (C.C.P.A. 1955).).
