Office Action

§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 . Election/Restrictions Applicant’s election without traverse of Species III, i.e. claims 73-78, 81, 83 and newly submitted claims 88-95 in the reply filed on November 24, 2025 is acknowledged. The examiner notes that the listing of the elected claims, per the ‘Applicant’s Remarks’ filed on November 24, 2025 is different then the claims listed above. The applicant states that the election involves claims 73-79, 81-83 and 88-95. Per the restriction requirement submitted on October 2, 2025, claim 79 is part of the ‘species II’ grouping and claim 82 is of the ‘species I’ grouping (and is currently cancelled). Based on the election and the claims grouped in the restriction requirement responded to, the above claims will be examined. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 68, 73-78, 81, 83 & 88-95 is/are rejected under 35 U.S.C. 103 as being unpatentable over Biel et al. (US 20180168508) in view of Hresko et al. (US 2017/0296056). Biel et al. discloses: Claim 68 An externally worn defibrillation device comprising: a sensor interface that includes physiological signal circuitry that is coupled to an electrocardiogram sensing electrode that is configured to be applied to a skin of a patient wearing the defibrillation device, wherein the physiological signal circuitry is configured to generate an electrocardiogram signal that is representative of cardiac activity of the patient; E.G. via the disclosed external, wearable medical device 100 in the form of a garment 110 , that further includes sensing electrodes 112 that are configured to detect one or more cardiac signals {[0058]-[0061] & (Fig 1)}. therapy delivery circuitry that is coupled to a therapy electrode that is configured to provide an electrical therapeutic shock to the patient; E.G. via the disclosed therapy delivery interface 302 that is coupled to the therapy electrodes 114 that provide therapy to the patient {[0068]-[0069] & (Fig. 3)}. at least one processor configured to process the electrocardiogram signal and control the therapy delivery circuitry to cause the electrical therapeutic shock to be provided to the patient: E.G. via the disclosed at least one processor 318 {[0069] & (Fig 3)}. detachment circuitry that is configured to detect a condition that is indicative of presence or absence of an electrical connection E.G. via the disclosed medical device controller 120 further comprising an electrode falloff detector 324 configured to monitor and to identify elemental fall off during operation of the wearable medical device ([0073]-[0074]). alarm circuitry configured to, based on absence of the electrical connection, generate an alert E.G. via the disclosed alarm module 326 based on the alarm profiles/conditions stored in data storage, wherein said profiles/conditions are directly related to the data obtained via the falloff detector 324 {[0076] & (Table)}. and a user interface configured to output the alert to the patient wearing the defibrillation device. E.G. via the disclosed user interface 308 coupled to the processor 318, which is further configured to delivery a ‘type of alarm’ such as an audible or visual alert and/or notification to the patient {[0076] & (Table)}.
