Regarding Claim 23, Best teaches the surface cleaning apparatus (vacuum cleaner, 10) wherein the power cord (100) comprises a direct current power connector whereby (Page 10, lines 18 – 34), when the power cord (100) is connected to the surface cleaning apparatus (10) and when the direct current power connector is connected to an electrical outlet (Page 11, line 34 – Page 12, line 12), power is provided to the surface cleaning apparatus (10; Page 10, lines 18 – 34). Regarding Claim 24, Best teaches the surface cleaning apparatus (vacuum cleaner, 10) wherein the power cord (100) comprises a power supply to convert alternating current to direct current which is then supplied to the suction motor (64; Claim 6). Regarding Claim 25, Best teaches the surface cleaning apparatus (vacuum cleaner, 10) wherein the suction motor (64) is operable on direct current supplied by the power cord and direct current supplied by the energy storage member (Page 11, line 34 – Page 12, line 12; claim 6).

Regarding Claim 40, Best teaches the surface cleaning apparatus (vacuum cleaner, 10) wherein the surface cleaning head (14) comprises a brush motor (brush motor, 106) and, when the portable cleaning unit (16) is mounted to the upright section (19), the upright section (19) is mounted to the surface cleaning head (14), the portable cleaning unit (16) is switched on, the brush motor (106) is operable on power provided by the portable cleaning unit (16; Page 11. Lines 13 – 34). 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. Claims 27 and 37 are rejected under 35 U.S.C. 103 as being unpatentable over Best (WO 2005/084511A1) in view of Yoo et al. (U. S. Patent Publication No. 2008/0297101 A1). Regarding Claims 27 and 37, Best teaches the surface cleaning apparatus of claims 26 and 36 as discussed above. Best does not teach the suction motor has dual windings. Yoo, however, teaches an analogous cleaner (Abstract) with a motor having dual winding (Paragraph [0006]). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Best to further include a motor having dual windings, as taught by Yoo, to provide a apparatus that provides a higher suction power and consistent performance thus proving a superior cleaning of the surface.
