§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 In the amendments filed November 14th, 2025, the following has occurred: claims 1, 11, and 17 have been amended; claims 1-2,4-11 and 13-20 remain pending in this application. 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. 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) 1, 2, 4, 5, and 8-10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Jang (WO 2013157669 A1, “Jang”) in view of Kumar et al. (WO 2018191425 A1, “Kumar”). Regarding claim 1, Jang discloses a method of delivering the object related message by using the wide-frequency sound signal, comprising: connecting one or more sound signal transmitters to one or more objects respectively (Fig. 3, [attached machine translation, pg. 6], speaker (311) is connected to health measuring device (210)); transmitting one or more messages related to one or more properties of the one or more objects by the one or more wide-frequency sound signal transmitters respectively ([attached machine translation, pg. 7] controller extracts unique code information for each health measurement which are provided to the DTMF module and transmitted through the speaker),; and receiving the one or more sound signals by a sound signal receiver. ([attached machine translation, pg. 7], microphone of terminal receives the transmitted signal from the speaker) Jang may not explicitly teach a wide-frequency transmitter, a wide-frequency receiver, and a wide-frequency signal, wherein the wide-frequency sound signal is an ultrasound signal; wherein the one or more object related messages are carried at the format of the sound signals via one or more waveform variations. Kumar teaches a wide-frequency transmitter, a wide-frequency receiver, and a wide-frequency signal; wherein the wide-frequency sound signal is an ultrasound signal. (Fig. 10, [pg. 18], (1002a-1002e) illustrate acoustic receivers such as transducers, microphones transceivers.

Regarding claim 2, Jang, as modified in view of Kumar, teaches the method according to claim 1. Kumar further teaches using one and only one wide- frequency sound signal receiver and a plurality of wide-frequency sound signal transmitters. ([pg. 26], in some embodiments, multiple acoustic transmitters can be situated while an acoustic receiver is moved through a detection volume to act as a reference positions for calibration) Regarding claim 4, Jang, as modified in view of Bandy, teaches the method according to claim 1.

Kumar further teaches further comprising analyzing the received one or more wide-frequency sound signals to decide the one or more properties of the one or more objects. ([pg. 17], in representative examples, methods use one or more wideband signals for ranging. Frequencies may include ranges from Hz to kHz, kHz to multiple kHz, tens of kHz, etc. and may include ultrasonic ranges as well, such as 40 kHz or higher)([pg. 22-23], communication connections enable communication over a communication medium such as acoustic transmit and receive signals in a modulated data signal that can have properties changed so as to encode information in the signal). Regarding claim 8, Jang, as modified in view of Kumar, teaches the method according to claim 1. Jang further teaches comprising connecting one or more detectors to the one or more objects respectively, wherein at least one object is connected to a wide-frequency sound signal transmitter and one or more detectors at the same time, wherein one or more contents of one or more object properties detected by one or more detectors are transmitted at the format of the wide- frequency sound signal.([attached machine translation, pg. 4], health measuring device includes a plurality of measuring pads to gather health data) ([attached machine translation, pg. 7] controller extracts unique code information for each health measurement which are provided to the DTMF module and transmitted through the speaker)(it is the examiner’s interpretation that one of ordinary skill in the art could reasonably apply the wide-frequency signal generation capabilities of Kumar to the detectors and transmitter of Jang) Regarding claim 9, Jang, as modified in view of Kumar, teaches the method according to claim 8. Jang further teaches comprising at least one of the following: placing a pressure detector positioned under a weight pan to detect the weight of any goods placed on the weight pan, and transmitting a wide-frequency sound signal carrying the weight message; and placing a touch detector under and separated from a suspended terminal of a seesaw-like device, such that a warning message is carried by a transmitted wide- frequency sound signal when the weight placed on the suspended terminal exceeds a critical value so that the suspend terminals falls and touches the touch detector.(Fig. 2 illustrates measuring pads (213) positioned around a scale in order gather health data)(([attached machine translation, pg. 5], health measuring device (210) is a device measuring any one or more of various health parameters including body weight)(it is the examiner’s interpretation that this would indicate the measuring pads (213) acting as pressure detector)([attached machine translation, pg. 7] controller extracts unique code information for each health measurement which are provided to the DTMF module and transmitted through the speaker) Regarding claim 10, Jang, as modified in view of Kumar, teaches the method according to claim 1. Jang further teaches comprising using one and only one host with at least one embedded wide-frequency sound signal receiver to receive at least one wide-frequency sound signal transmitted from at least one wide-frequency sound signal transmitter embedded in at least one fitness equipment respectively. ([attached machine translation, pg. 7], microphone of terminal receives the transmitted signal from the speaker)(Fig. 2 (220) is a terminal in the form of a mobile device such as a smartphone which the examiner interprets to be equivalent to a host)(it is the examiner’s interpretation that one of ordinary skill in the art would be reasonably motivated to implement the wide-frequency transmitters and receivers in the fitness equipment of Jang) Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Jang in view of Kumar and Sanders et al. (WO 2005019838 A1, “Sanders”). Regarding claim 6, Jang, as modified in view of Kumar, teaches the method according to claim 5. Jang, as modified in view of Bandy may not explicitly teach further comprising deciding the relative motion between a certain wide-frequency sound signal transmitter and the wide-frequency sound receiver by analyzing the frequency variation of the wide-frequency sound signal transmitted therebetween by reference to the Doppler effect. Sanders further comprising deciding the relative motion between a certain wide-frequency sound signal transmitter and the wide-frequency sound receiver by analyzing the frequency variation of the wide-frequency sound signal transmitted therebetween by reference to the Doppler effect.([pg. 3], transmitter transmits a wideband acoustic signal to the receiver which is configured to measure any doppler frequencies added to the transmit signal as a result of relative movement of the body)([pg. 6]motion of the swimmer is overlaid onto video imagery of the swimmer carrying the device in the pool) Therefore, it would have been prima facie obvious to one of ordinary skill in the art of acoustic communications, before the effective filing date of the claimed invention, to modify the method of Jang, as modified in view of Kumar, to include the doppler frequency analysis of Sanders with a reasonable expectation of success, with the motivation of accounting for any changes in frequency of the received waves due to the doppler effect in order to accurately track the motion of the transmitter [pg. 3]. Claim(s) 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Jang in view of Kumar and Connellan et al. (US 20190113966 A1, “Connellan”). Regarding claim 7, Jang, as modified in view of Kumar, teaches the method according to claim 5. Jang, as modified in view of Kumar, may not explicitly teach further comprising at least one of the following: deciding the relative distance variation between a certain wide-frequency sound signal transmitter and the wide-frequency sound signal receiver by analyzing the intensity variation of the wide-frequency sound signal transmitted therebetween by reference to the phenomena that the intensity is inversely proportional to the relative distance in the three-dimensional space; and deciding the relative distance between a certain wide-frequency sound signal transmitter and the wide-frequency sound signal receiver by analyzing the intensity variation of the wide-frequency sound signal transmitted therebetween by reference to the phenomena that the intensity is inversely proportional to the relative distance in the three-dimensional space if the default signal intensity of the certain wide-frequency sound signal transmitter is known. Connellan teaches deciding the relative distance variation between a certain wide-frequency sound signal transmitter and the wide-frequency sound signal receiver by analyzing the intensity variation of the wide-frequency sound signal transmitted therebetween by reference to the phenomena that the intensity is inversely proportional to the relative distance in the three-dimensional space([0134], distance can be measured by determining the intensity of the returning wave) Therefore, it would have been prima facie obvious to one of ordinary skill in the art of acoustic communications, before the effective filing date of the claimed invention, to modify the method of Jang, as modified in view of Kumar, to include the sound signal intensity analysis of Connellan with a reasonable expectation of success, with the motivation of determining the distance travelled by the wave which correlates to the distance between the transmitter and receiver [0134].

([pg. 17], in representative examples, methods use one or more wideband signals for ranging. Frequencies may include ranges from Hz to kHz, kHz to multiple kHz, tens of kHz, etc. and may include ultrasonic ranges as well, such as 40 kHz or higher) Therefore, it would have been prima facie obvious to one of ordinary skill in the art of acoustic communications, before the effective filing date of the claimed invention, to modify the fitness equipment of Sanders, to include the operational frequency of Kumar with a reasonable expectation of success, with the motivation of making the system more resilient to ambient acoustic noise, rejecting echoes, and reducing sensitivity to resonances of the microphone and speakers [pg. 17-18]. Regarding claim 13, Sanders, as modified in view of Kumar teaches the intelligent fitness equipment according to claim 11.
