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 Amendment Applicant’s amendments of claims 33-52 are acknowledged by the Examiner. Applicant’s amendments of claims 33, 48, and 50-52 have overcome the previous claim objections. Therefore, the claim objections are withdrawn. Applicant’s amendments of claims 33-35, 37, 39, 42, 47, and 52 have overcome the previous claim rejections under 35 U.S.C. 112(b). Therefore, the claim rejections under 35 U.S.C. 112(b) are withdrawn. Applicant’s amendment of claims 34-51 have overcome the previous rejections under 35 U.S.C. 112(d). Therefore, the claim rejections under 35 U.S.C. 112(d) are withdrawn. Claims 33-52 are pending in the current Application. Response to Arguments Applicant’s arguments with respect to claim(s) 33-52 have been considered but are moot because the new ground of rejection does not rely on the primary reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Objections Claim 33, and 49 are objected to because of the following informalities: Claim 33 recites the limitation “for applying stimulation to the one or more muscles of the mouth” in lines 3 and 5, and “wherein a tongue of the user is located between”. Each of these limitations should be amended to include configured to language. Claim 49 recites the limitation “for overlying at least a portion…of the user’s tongue”. This limitation should be amended to include configured to language. Appropriate correction is required. 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 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. Claim(s) 35-37, and 43-45 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sama in view of Kasahara et al. (JP 6150331 B2) (hereinafter Kasahara; Examiner relies on a machine translation of Kasahara provided by Espacenet.com). In regards to claim 35, Sama discloses the invention as discussed above. Sama further discloses wherein the impedance sensor (impedance sensing system) is configured to evaluate the composition of the tongue (through electric impedance tomography) at multiple frequencies (see [0195]) Sama does not disclose the multiple frequencies is up to 100 kHz. However, Kasahara teaches an analogous apparatus (100; see [0016]; see figure 1) for determining a composition of one or more muscles of the mouth of a user (see [0016] a tongue is a muscle of the mouth; see [0024] in reference to the determination of the composition of the user’s tongue); the apparatus (100) comprising a mouthpiece (10; see [0017]; see figure 1) including one or more electrodes (12a-b; see [0017]; see figure 1) for applying electrical stimulation to one or more muscles of the mouth of a user (see [0017]) and a sensing assembly (23; see [0022]; see figure 4) configured or configurable to determine or measure, in use, the composition of a tongue of the user (see [0023], and [0026-0028]); wherein the impedance sensor (12c) of the sensing assembly (23) is configured to evaluate the composition of the tongue (see [0026-0028] at multiple frequencies up to 100 kHz (see [0023]) for the purpose of allowing the current to flow through the internal structures of the tongue (see [0023]). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the multiple frequencies for measuring the composition of the tongue as disclosed by Sama and to have utilized frequencies up to 100kHz as taught by Kasahara in order to have provided an improved apparatus that would add the benefit of providing a frequency of electrical stimulation which allows the current to flow through the internal structures of the tongue (see [0023]) thereby increasing the capability of the electrical impedance tomography disclosed by Sama to fully image the tongue. In regards to claim 36, Sama as now modified by Kasahara discloses the invention as discussed above. Sama further discloses wherein the sensing assembly (measuring means) is configured to evaluate the tongue composition at a single frequency overtime (the software may be programmed to generate impedance information using the impedance sensors of the measuring means during monophasic currents; see [0195]). In regards to claim 37, Sama as now modified by Kasahara discloses the invention as discussed above. Sama further discloses wherein the sensing assembly (measuring means) is configured to evaluate the tongue composition at multiple frequencies over time during a sampling window between 0 to 90 seconds (software program may be programmed to apply monophasic and biphasic currents having different frequencies and for different periods of predetermined time (see [0195]), and may run measurement of impedance during said period (see [0195]); said predetermined time (i.e. the sampling window) may be 1 minute (see [0194]) In regards to claim 43, Sama discloses the invention as discussed above. Sama does not disclose wherein the sensing assembly is configured to determine or measure the tongue composition by determining or measuring a volumetric or mass ratio of muscle to fat of the tongue of the user. However, Kasahara teaches an analogous apparatus (100; see [0016]; see figure 1) for determining a composition of one or more muscles of the mouth of a user (see [0016] a tongue is a muscle of the mouth; see [0024] in reference to the determination of the composition of the user’s tongue); the apparatus (100) comprising a mouthpiece (10; see [0017]; see figure 1) including one or more electrodes (12a-b; see [0017]; see figure 1) for applying electrical stimulation to one or more muscles of the mouth of a user (see [0017]) and a sensing assembly (23; see [0022]; see figure 4) configured or configurable to determine or measure, in use, the composition of a tongue of the user (see [0023], and [0026-0028]); wherein the sensing assembly (23) is configured to determine or measure the tongue composition by determining or measuring a volumetric or mass ratio of muscle to fat of the tongue of the user (23 through sensing provided by 12c, 12d, calculations provided by 31, and voltage provided from 24 determines the composition of the tongue using two cross sectional areas of the tongue, which are separated by a distance L, (said two cross sections depicting a mass ratio of muscle to fat; see [0036], [0039], and [0046]; see figure 9b) over which 12c and 12d are placed, and 30 consequently uses pre-programmed calculations which use the measured values for determining the tongue composition; see [0034-0050]) for the purpose of stably obtaining a predetermined measurement accuracy of the tongue composition (see [0006]). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the sensing assembly as disclosed by Sama and to have configured the sensing assembly to determine or measure the tongue composition by determining or measuring a volumetric or mass ratio of muscle to fat of the tongue of the user as taught by Kasahara in order to have provided an improved apparatus that would add the benefit of stably obtaining a predetermined measurement accuracy of the tongue composition (see [0006]). In regards to claim 44, Sama discloses the invention as discussed above. Sama does not disclose wherein the sensing assembly is configured to determine or measure the tongue composition by determining or measuring a total volume or mass of muscle and/or fat of the tongue of the user. However, Kasahara teaches an analogous apparatus (100; see [0016]; see figure 1) for determining a composition of one or more muscles of the mouth of a user (see [0016] a tongue is a muscle of the mouth; see [0024] in reference to the determination of the composition of the user’s tongue); the apparatus (100) comprising a mouthpiece (10; see [0017]; see figure 1) including one or more electrodes (12a-b; see [0017]; see figure 1) for applying electrical stimulation to one or more muscles of the mouth of a user (see [0017]) and a sensing assembly (23; see [0022]; see figure 4) configured or configurable to determine or measure, in use, the composition of a tongue of the user (see [0023], and [0026-0028]); wherein the sensing assembly (23) is configured to determine or measure the tongue composition by determining or measuring a total volume or mass of muscle and/or fat of the tongue of the user (23 through sensing provided by 12c, 12d, calculations provided by 31, and voltage provided from 24 determines the composition of the tongue using two cross sectional areas of the tongue, which are separated by a distance L, (total mass of fat calculated in [0049]) over which 12c and 12d are placed, and 30 consequently uses pre-programmed calculations which use the measured values for determining the tongue composition; see [0034-0050]) for the purpose of stably obtaining a predetermined measurement accuracy of the tongue composition (see [0006]). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the sensing assembly as disclosed by Sama and to have configured the sensing assembly to determine or measure the tongue composition by determining or measuring a total volume or mass of muscle and/or fat of the tongue of the user as taught by Kasahara in order to have provided an improved apparatus that would add the benefit of stably obtaining a predetermined measurement accuracy of the tongue composition (see [0006]). In regards to claim 45, Sama discloses the invention as discussed above. Sama does not disclose wherein the sensing assembly is configured to determine or measure the tongue composition by determining or measuring a mass or volume of one or more types of muscle of the tongue of the user. However, Kasahara teaches an analogous apparatus (100; see [0016]; see figure 1) for determining a composition of one or more muscles of the mouth of a user (see [0016] a tongue is a muscle of the mouth; see [0024] in reference to the determination of the composition of the user’s tongue); the apparatus (100) comprising a mouthpiece (10; see [0017]; see figure 1) including one or more electrodes (12a-b; see [0017]; see figure 1) for applying electrical stimulation to one or more muscles of the mouth of a user (see [0017]) and a sensing assembly (23; see [0022]; see figure 4) configured or configurable to determine or measure, in use, the composition of a tongue of the user (see [0023], and [0026-0028]); wherein the sensing assembly (23) is configured to determine or measure the tongue composition by determining or measuring a mass or volume of one or more types of muscle of the tongue of the user (23 through sensing provided by 12c, 12d, calculations provided by 31, and voltage provided from 24 determines the composition of the tongue using two cross sectional areas of the tongue, which are separated by a distance L, (muscle portion, and therefore a mass of the muscle portion calculated in [0049]) over which 12c and 12d are placed, and 30 consequently uses pre-programmed calculations which use the measured values for determining the tongue composition; see [0034-0050]) for the purpose of stably obtaining a predetermined measurement accuracy of the tongue composition (see [0006]). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the sensing assembly as disclosed by Sama and to have configured the sensing assembly to determine or measure the tongue composition by determining or measuring a mass or volume of one or more types of muscle of the tongue of the user as taught by Kasahara in order to have provided an improved apparatus that would add the benefit of stably obtaining a predetermined measurement accuracy of the tongue composition (see [0006]). Claim(s) 46 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sama in view of Takesada (JP 2015/093133 A) (Examiner relies on a machine translation of the reference retrieved from Espacenet.com). In regards to claim 46, Sama discloses the invention as discussed above. Sama does not disclose wherein the sensing assembly is configured to determine or measure the tongue composition by determining or measuring a relative ratio of a first type of muscle to a second type of muscle of the tongue of the user. However, Takesada teaches an analogous apparatus (biometric device; see [0001]) comprising an analogous sensing assembly (24; see [0013]; see figure 1) for the analogous purpose of sensing a body composition of a user utilizing an impedance of the user’s body (see [0020]) wherein the sensing assembly (24) is configured to determine or measure the body composition by determining or measuring a relative ratio of a first type of muscle to a second type of muscle of the body of the user (see [0028] in reference to the impedance measured being that of the incisor muscles, the tongue, the suprahyoid muscles, and hyoid bone muscles; thereby disclosing the sensing assembly is configured to determine the musculature composition based on fat, and the aforementioned muscles) for the purpose of performing an accurate evaluation of the measured body (see [0045]). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the sensing assembly as disclosed by Sama and to have configured the sensing assembly to measure the tongue composition by measuring first and second types of muscles of the body of the user as taught by Takesada in order to have provided an improved sensing assembly that would add the benefit of being able to sense a relative ratio of multiple muscle types for the purpose of performing an accurate evaluation of the measured body (see [0045]). 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).
