As for claim 14, Carbunaru discloses coil manipulator comprises one or more electrical switches that selectively activate and deactivate coils in the array of coils (par.[0053]) As for claim 15, Carbunaru discloses and shows in FIG. 7C configuration of the at least one coil is adjusted to maximize charging efficiency between the at least one coil and the implantable medical device (par.[0048]) As for claim 16, Carbunaru discloses and shows in FIG. 7C a system comprising: a chargeable device having a receiver coil; and a charging device comprising: a charging coil provided on a support substrate (via ref’s coil plate) that wirelessly transfers energy to the receiver coil; and a coil manipulator (ref’s actuator) that changes a configuration of the charging coil to improve an efficiency with which the energy is wirelessly transferred to the receiver coil during a charging session, wherein changing the configuration of the charging coil comprises at least one of moving and rotating the support substate (par.[ 0007-0014,0034,0048,0058]). As for claim 17, Carbunaru discloses at least one sensor that provides a sensor reading to determine an efficiency with which the energy is wirelessly transferred to the receiver coil during the charging session (par.[0045-0046]). As for claim 18, Carbunaru discloses the at least one sensor comprises one or more of an electromagnetic sensor, an optical sensor, an acoustic sensor, a mechanical sensor, and a thermal sensor (par.[0045-0046]). As for claim 19, Carbunaru discloses and shows in FIG. 7C wherein the coil manipulator at least one of physically moves the charging coil or adjusts an RF field produced by the charging coil As for claim 20, Carbunaru discloses and shows in FIGs. 7C and 8 a system comprising: a housing (ref’ external charging housing); a charging coil provided on a support substrate (via ref’s coil plate) contained within the housing; and a coil manipulator (ref’s actuator) that physically moves the charging coil in the housing (par.[0007-0014,0034,0058]). As for claim 21, Carbunaru discloses and shows in FIGs. 7C and 8 moving and rotating the support substrate adjusts an RF field produced by the charging coil. As for claim 22, Carbunaru discloses and shows in FIGs. 7C and 8 adjusting the RF field produced by the charging coil comprises placing a stronger portion of the RF field over the receiver coil in the chargeable device. As for claim 23, Carbunaru discloses and shows in FIGs. 7C and 8 at least one sensor that provides a sensor reading to determine an efficiency with which the energy is wirelessly transferred to the receiver coil during the charging session (par.[0048]). 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Schommer et al, (Schommer), (USNO.2005/0075700). As claim 12, Carbunaru discloses all limitations, but differs from the claimed invention because he does not explicitly disclose at least one coil comprises a single coil. Schommer discloses and shows in Figs. 3 and 12 Schommer discloses and shows in at least one coil comprises a single coil (par.[0060]) Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention was made to have modified the teachings of Carbunaru by using the at least one coil within the housing for advantages such as providing more closely be aligned with secondary coil (par.[0060]) , as taught by Schommer. Response to Arguments Applicant's arguments filed 2/26/07 have been fully considered but they are not persuasive. In response to applicants’ argument that Applicant respectfully submits that Schommer does not remedy the above-noted deficiencies of Carbunaru with respect to the feature of a coil manipulator that adjusts a configuration of the at least one coil within the housing by at least one of moving and rotating the support substrate, as recited in claim 1 The examiner respectfully disagree and submits, Carbunaru discloses and shows in FIG. 7C a charging device comprising: at least one coil provided on a support substate (via ref’s coil plate) contained in a housing (ref’ external charging housing), wherein the at least one coil wirelessly transfers energy to an implantable medical device; and a coil manipulator (ref’s actuator) that adjusts a configuration of the at least one coil within the housing by at least one of moving and rotating the support substrate (par.[ 0007-0014,0034,0048,0058]) as claimed necessitated by amendment For at least the reasons provided above, the applicant arguments regarding independent claims are not persuasive. The applicant argues that dependent claims are patentable for similar reasons and are also not persuasive. The applicant further argues that since dependent claims depend on the argued independent claim; they are patentable at least by virtue of their dependencies. Since the applicant's arguments regarding independent claims are not persuasive, the applicant's arguments regarding dependent claims are also not persuasive. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.
