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 5-6,15-16 are rejected under 35 U.S.C. 103 as being unpatentable over Ku as applied to claims 5-6, 15-16 above, and further in view of Babin (Patent No. 5,941,974). Regarding claims 5-6, 15-16, Ku discloses the claimed invention except for n is an even number, Babin teaches that it is know in the art to provide the n levels is an even number of sub-shift circuits in Figure 1, 57, 59. It would have been obvious to one having ordinary skill in the art at the time the invention was made to arrange the sub-shift circuits is an even number levels, since it has been held that arrangements of an element and its function and general conditions in a combination where the remaining elements perform the same functions as before involves only routine skill in the art.
