Claims 1-20 have been presented and pending in the application. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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) 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over IM (US 2008/0222378 A1).

The teachings of the claim 6 are similarly, since the claim 13 is not patentable distinct from the claim 6 The examiner notes that the IM reference does not: 1) expressly or identically uses the term “sub-channel”; and 2) does not expressly or identically disclose memory locations with its stored data. However, such not expressly or disclosed limitations are well-known types or functionally equivalent variations that are obvious substitutions and/or modifications that can easily made by one skilled in the art, when designing a functionally equivalent system(s). As for the claimed 1) sub-channel labeling difference, the CH0-CH4 of figures 4-6 with accompanying description teaches the functionally equivalent limitations of the claimed invention. As for the claimed 2) memory locations with its stored data, one skilled in the art can easily choose, for providing functional equivalent system, to utilize or to store different, but functionally equivalent, types of data & locations for performing or accomplishing equivalent functions of the claimed invention. Therefore, it would have been obvious before the effective filing date of the claimed invention to one having ordinary skill in the art to come up with the claimed invention from the functionally equivalent teachings of the IM reference for the detailed teachings & reasons discussed above.
