DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1 is/are rejected under 35 U.S.C. 103 as being unpatentable over Komatsubara et al. (JPH07188755A) . Regarding Claim 1 , Komatsubara teaches a method of forming a grain-oriented silicon steel sheet comprising: Preparing a cold-rolled steel sheet having a chemical composition containing 0.01% mass of C or more [0028] and 1.0% Si or more [0020] ; Subjecting the steel to decarburization annealing [0011]; Applying a MgO-based annealing separator to a surface of the steel sheet [003 7 ]; Drying the annealing separator by baking [0028] ; Coiling the sheet; and subjecting the sheet to final annealing. [0011] The prior art is silent regarding the step of storing the sheet after coiling; however, one of ordinary skill in the art would have been motivated to store a coiled electrical sheet to prevent deformation, corrosion and property degradation before it is transferred to a new unit operation which may be in a different part of the plant or different location to undergo final annealing. As the silicon steel sheet is made by a substantially identical meth od; one of ordinary skill in the art would have expected the annealing separator after drying to have similar properties based on storage time and carbon dioxide composition as required by formula (1) under the expectation that substantially identical products have similar properties ( See MPEP 2112.01(I) ).
