Office Action

§102 §103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s arguments with respect to claim(s) 1, 5, 8 and 22 have been considered but are moot due to new grounds of rejections cited below. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim 1, 5 and 24 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Marchitto et al. (US 20040236269). Regarding claim 1, Marchitto et al. teach A sensor device for detecting properties of a skin area (Note abstract) comprising: at least one sensor unit;(50, Fig. 4) and a support device (membrane 18, par. 0101) connected to the sensor unit, wherein the support device can be connected to the skin area to be detected, wherein the sensor unit comprises a transmitter for outputting an electrical and/or magnetic signal to the skin area to be detected,(Note claim 32, a source of an alternating magnetic field to generate eddy currents in said tissue) and a receiver for measuring a signal originating from the skin area, which signal results from the signal output by the transmitter, (Note claim 32, a detector to detect said eddy currents) wherein the at least one sensor unit comprises an eddy current testing device, (Note claim 32, a controller to monitor said eddy currents) and wherein the sensor device is configured to measure an impedance of the skin area. (Note par. 0024, An electric current generated between active and return electrodes at the site of interest or eddy currents at the site of interest generated via an alternating magnetic field may be monitored to provide information about conductivity, impedance or hydration of the altered tissue.) Regarding claim 5, Marchitto et al. teach the transmitter and/or the receiver comprise a coil. ([0066] Alternatively, feedback control of electrical conductivity of the treated tissue is achieved by using applied magnetic fields and monitoring the eddy currents in the target tissue. By exposing the treated tissue to a magnetic field, for example, at a frequency between 1 kHz and 2.4 GHz, which may be produced by an induction coil or other source that generates an alternating magnetic field, eddy currents are generated in the tissue. Eddy currents induced by a changing magnetic field concentrate near the surface adjacent to an excitation coil.) Regarding claim 24, Marchitto et al. teach wherein the at least one sensor unit is insulated and/or configured to be spaced apart from the skin, such that the at least one sensor unit is not in direct contact with the skin when the sensor device is connected to the skin. (Note ablation site 19. Fig. 4, (0104 FIG. 4 depicts an alternate embodiment of the device 50. A piezoelectric actuator 12 functioning as a vibrating probe is associated with at least one electrode 42 that is in electrical contact with the ablation site 19 of the membrane 18.) Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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 22 are rejected under 35 U.S.C. 103 as being unpatentable over Marchitto et al. (US 20040236269) Brettschneider et al. (DE 102015225847 A1). Marchitto et al. teach the instant invention except the following claim limitations. Regarding claim 22, Marchitto t et al. does not teach wherein the sensor device detects an active ingredient in a skin area. Brettschneider et al. teach wherein the sensor device detects an active ingredient in a skin area.
