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 8 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over 653’ in view of Kikinis et al. (US 2010/0327807), hereinafter Kikinis. As to Claim 8, 653’ discloses all of the claim limitations except wherein the control system is configured to control the switch circuitry of each module such that a duty cycle of the plurality of charge pulses is based on a number of modules in the plurality of modules or a number of modules being charged. Kikinis discloses in figure 1, wherein the control system is configured to control the switch circuitry of each module such that a duty cycle of the plurality of charge pulses is based on a number of modules in the plurality of modules or a number of modules being charged [Pulse width modulation/the default duty cycle is adjusted based on to control the switches and it depends on the number of batteries, see figure 7 and also ¶0079 and ¶0085]. It would have been obvious to one ordinary skill in the art before the effective filling date of the claimed invention was made to adjust the duty cycle of charging pulse of 653’ to 50% in as taught by Chai in order to enhance the efficiency of the battery. As to Claim 19, 653 in combination with Kikinis discloses, wherein the control system is configured to control the switch circuitry of each module in each group of modules such that a duty cycle of the plurality of charge pulses is based on a number of groups in the plurality of groups of modules [653’ discloses pulse width modulation is used to control the switches and it implies the duty cycle of the pulses are adjusted; see ¶0067 and adjusting the duty cycle based on battery numbers are disclosed by Kikinis]. It is also noted that all the claimed elements of applicant’s inventions were known in the prior art (e.g. battery parameter sensing, adjusting duty cycle based on battery parameters and etc.,) and one skilled in the art could have combined the elements as claimed by known methods with no change in their respective functions, and the combination would have yielded predictable results to one of ordinary skill in the art at the time of the invention, proper motivation/rationale to combine is as given in the office action. See KSR, 127 S. Ct. at 1740, 82 USPQ2d at 1396. Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over 653’ in view of Chait et al. (US 7,786,702), hereinafter Chait.
