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. Claims 4, 10-11 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Lyster et al. (US 20030055478 A1). As to claim 4, Lyster et al. discloses determining useful lifespan of the conductive gel and assessing if a conductive gel is unusable based on exceeding a threshold ([0117, 0247-0249]) but does not explicitly disclose the threshold is an impedance value for the conductive gel is greater than or equal 600 to 800 ohms. It would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the threshold range od Lyster et al., since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233 (see MPEP 2144.05). Furthermore, such a modification would provide the predictable results of ensuring sufficient operational parameters. As to claims 10 and 19, Lyster et al. discloses a non-implantable electrical stimulation device further comprises a storage box (Figure 30; [0259-0262]), the storage box comprises an upper cover and a lower cover, the upper cover and the lower cover form an accommodating space, and the accommodating space is configured to accommodate the electrical stimulator and the electrode assembly storage box (Figure 30; [0259-0262]) and determination of the useful lifespan of the conductive gel (Abstract, Figures 27-31), comprises: deducting an impedance value of the electrical stimulator, an impedance value of the electrode assembly excluding the conductive gel and an impedance value of the impedance component from the first total impedance, so as to obtain the impedance value of the conductive gel and determine the useful lifespan of the conductive gel ([0200-0214]). Lyster et al. additionally discloses a circuit board and an isolation component, wherein the conductive area is the circuit board that comprises a first metal trace, a second metal trace and an impedance component, the impedance component is connected between the first metal trace and the second metal trace, and the isolation component is disposed on the circuit board and exposes the first metal trace and the second metal trace (Figures 27-31; [0258-0262]). Thus, Lyster et al. discloses the circuit board and isolation component in the upper cover ([0261]; Figure 30) but does not explicitly disclose the option of placing the circuit board and isolation component are located in the lower cover. It would have been obvious to one having ordinary skill in the art at the time the invention was made to modify the location of circuit board and isolation component from the upper cover to the lower cover, since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 86 USPQ 70 (see MPEP 2144.04). As to claim 11, the modified Lyster et al. discloses the impedance value of the electrical stimulator and the impedance value of the electrode assembly excluding the conductive gel are ignored, and the impedance value of the conductive gel is the first total impedance value deducting the impedance value of the impedance component ([0127, 0140-0142, 0165-0169]).
