Claims 1-20 are pending in this office action.
Response to Arguments
Applicant's arguments filed 3/23/26 have been fully considered but are moot in view of new grounds of rejection.
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.
Claims 1, 2 and 4-20 are rejected under 35 U.S.C. 103 as being unpatentable over Nokkonen et al (WO 2013/060802 A1) in view of Reed (US 2023/0028436 A1).

Nokkonen does not explicitly disclose the radio is operating on a predetermined schedule of operation of radio transmissions and radio reception.
Reed teaches radio is operating on a predetermined schedule of operation of radio transmissions and radio reception (Reed: Figs. 1-2; [0031]; [0096], battery level drop based on active period/schedule of a radio transmission).

Nokkonen does not explicitly disclose receiving the schedule of operating of radio transmissions and radio reception.
Reed teaches receiving the schedule of operating of radio transmissions and radio reception (Reed: Figs. 1-2; [0031]; [0096], battery level drop based on active period/schedule of a radio transmission).
It would have been obvious to a person having an ordinary skill in the art before the effective filling date of the claimed invention to modify the system of Nokkonen by receiving the schedule of operating of radio transmissions and radio reception as disclosed by Reed to provide a system for monitoring energy usage of battery powered wirelessly linked devices (Reed: Abstract).
Regarding claim 2, Nokkonen teaches wherein maintaining operation of the radio comprises maintaining a supply voltage greater than a reset voltage for the radio (Nokkonen: Fig. 1; [0029]-[0030] monitoring battery power and de-asserting an output signal PeakDet when voltage is above a threshold).
Regarding claim 4, Nokkonen teaches wherein the radio controller adjusts operation of the radio by changing the schedule to a lower frequency of radio operation when the output signal is inactive (Nokkonen: Figs. 1 and 4; [0029]-[0030] reduce the frequency of the processor clock).
Regarding claim 5, Nokkonen teaches wherein the radio controller is configured to provide a low voltage alert when the output signal is inactive (Nokkonen: Fig. 1; [0029], [0034] when the output signal PeakDet is asserted).
Regarding claim 6, Nokkonen teaches wherein the radio controller is configured to follow the predetermined schedule with a voltage check of the battery prior to every transmission or reception in the predetermined schedule, and to load throttle when the output signal is inactive (Nokkonen: Figs. 1-4; [0029]-[0030], [0034] monitoring battery power and de-asserting an output signal PeakDet when voltage is above a threshold).
Regarding claim 7, Nokkonen teaches wherein the radio controller is further configured to monitor the output signal during active transmissions and receptions of the radio, and to throttle transmissions and receptions when the output signal switches to inactive (Nokkonen: Figs. 1-4; [0029]-[0030], [0034] monitoring battery power and de-asserting an output signal PeakDet when voltage is above a threshold).
Regarding claim 8, Nokkonen teaches further comprising a bulk storage component coupled between the battery and the radio controller and configured to supply power for transmissions and receptions prior to using power from the battery (Nokkonen: Figs. 1-2; [0024]-[0028]).

Regarding claim 10, Nokkonen teaches wherein the bulk storage component comprises a bulk storage capacitor charged by the battery, and wherein when a transmission or reception according to the predetermined schedule is to be made, power for the radio is provided by enabling the bulk storage capacitor for powering the transmission or reception (Nokkonen: Figs. 1-2; [0024]-[0028], [0038]).
Regarding claim 11, Nokkonen teaches wherein the bulk storage component further comprises a power sharing resistor coupled between the battery and the bulk storage capacitor (Nokkonen: Figs. 1-2; [0024]-[0028], [0038]).
