Office Action

§101 §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 . Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 18-21 are rejected under 35 U.S.C. 101 because Section 33(a) of the America Invents Act reads as follows: Notwithstanding any other provision of law, no patent may issue on a claim directed to or encompassing a human organism. Claim 18 is rejected under 35 U.S.C. 101 and section 33(a) of the America Invents Act as being directed to or encompassing a human organism. See also Animals - Patentability, 1077 Off. Gaz. Pat. Office 24 (April 21, 1987) (indicating that human organisms are excluded from the scope of patentable subject matter under 35 U.S.C. 101). Claim 18 requires the target substrate and the disclosure and claim 19 clarify this is meant to be the heart. Thus, these claims include a human within the scope and are non-statutory. The examiner suggests using the phrase "adapted to be located" when referring to the location of the sensor device in relation to the heart. Dependent claims inherit the same deficiencies. The examiner notes claim 4 requires the implantation depth which also requires a human to obtain the depth of implantation. Claim Rejections - 35 USC § 102 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. Claim(s) 11-12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Almarri et al (N. ALMARRI, et al., "Self-Powered Piezoelectric Biosensing Harvester for Intracardiac Monitoring", 2023 IEEE Biomedical Circuits and Systems Conference (BioCAS), 10/19/23-10/21/2023, 4 pgs.) cited in IDS date 6/23/2025 in view of Babakhani et al (US Publication 2022/0158497).

Skinner et al teaches that it is known to use CMOS analog temperature sensor in an implantable device as set forth in Paragraph [0108] to provide improved determination of physiological performance with low power consumption. It would have been obvious before the effective filing date of the claimed invention to one having ordinary skill in the art to modify the system as taught by Almarri et al, with wherein the circuitry further comprising a CMOS-based temperature sensor as taught by Skinner et al, since such a modification would provide the predictable results of improved determination of physiological performance with low power consumption. Babakhani et al teaches that it is known to use On-Off Keying (OOK) oscillating transmitter connected to a dual-loop antenna as set forth in Figure 21 and Paragraphs [0069], [0097]-[0098] to provide a known technique for power-efficient short range communication module. It would have been obvious before the effective filing date of the claimed invention to one having ordinary skill in the art to modify the system as taught by Almarri et al, with On-Off Keying (OOK) oscillating transmitter connected to a dual-loop antenna as taught by Babakhani et al, since such a modification would provide the predictable results of a known technique for power-efficient short range communication module. Claim(s) 1, 3-4, 7-8, 10, and 13-15 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hunter et al (US Publication 2024/0164642). Referring to Claim 1, Hunter et al teaches a self-powered sensor device comprising: a harvester module having a power harvesting element, the power harvesting element being arranged and disposed to harvest power from induced mechanical strain (e.g. Figure 1, Element 24); a sensor module having a sensor element (e.g. Figure 1, Element 14); a controller module having circuitry operably connected to the harvester module and the sensor module, the controller module being configured to receive power from the power harvesting element, to receive sensor signals from the sensor element, and to wirelessly communicate an output signal corresponding to the sensor signal (e.g. Figure 1, Element 52); wherein the controller module is powered continuously with power harvested from the power harvesting element to generate and communicate the output signal (e.g. Figure 1, Element 24). Referring to Claim 3, Hunter et al teaches the device of claim 1, wherein the sensor device is powered only by mechanical cardiac motion (e.g. Figure 1 and Paragraph [0188]). Referring to Claim 4, Hunter et al teaches the device of claim 1, wherein the harvester module, the sensor module, and the controller module are mounted on a flexible carrier (e.g. Paragraph [0012]). Referring to Claim 7, Hunter et al teaches the device of claim 1, wherein the sensor element comprises at least one piezoelectric microelectromechanical system (MEMS) sensor (e.g. Paragraph [0101]). Referring to Claim 8, Hunter et al teaches the device of claim 1, wherein the sensor element includes a spatial sensing array (e.g. Paragraph [0101]). Referring to Claim 10, Hunter et al teaches the device of claim 1, wherein the circuitry includes a signal acquisition submodule operable to process biomechanical sensor signals and extract physiological cardiac metrics (e.g. Paragraph [0094] and Figures 1 , Elements 16 and 18).

Claim(s) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hunter et al (US Publication 2024/0164642). Referring to Claim 2, Hunter et al teaches the device of claim 1, except wherein the sensor device is devoid of batteries. The examiner notes that capacitors are used to store energy and that it would have been an obvious substitution of one known element for another (to replace the batteries of Hunter et al with capacitors as is known in the art) to provide the predictable results of longer cycle life. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Li et al (US Publication 2023/0149720) discloses an intracardiac energy harvesting device with sensors which can emit electrical energy such that a detected low heart rate will have the device generate current to the heart tissue to stimulate heartbeat.
