Office Action

§101 §102 §112
DETAILED ACTION 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 39-44, 48, 50-53, 55-56, 58-60, 62, 67-69 & 71-72, specifically independent claim 39, is rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception without significantly more. Please see the below analysis providing the details as to why the invention is directed towards non-statutory subject matter. Step 1: Claim 39 is directed to a method. Therefore, the claim falls within a statutory category of invention. Step 2A, prong 1: Claim 39 recites the method steps of: “receiving…at least one electrical signal determined based on monitored electrical activity…from a plurality of electrodes… “receiving…at least one motion signal based upon movement of the patient and generated by at least one motion sensor… “recording…a wear onset event based on one or more of the at least one electrical signal and the at least one motion signal…” “providing…a graphical representation of wear compliance of the patient based on the recorder wear onset event and the recorded wear offset event…” “receiving…one or more notification criteria from one or more of a caregiver of the patient or a prescriber of the wearable defibrillator…” “comparing…the patient’s wear compliance and the one or more notification criteria…” “outputting…a notification to one or more of the patient, the caregiver of the patient or the prescriber of the wearable defibrillator if the patient’s wear compliance… Under the broadest reasonable interpretation, claim 1 recites the method steps comprising mental processes (i.e. receiving, recording signals, providing, receiving, comparing and outputting based on event from said signals). Thus, since claim recites limitations within the mental processes the claim is directed to an abstract idea. Step 2A, prong 2: Claim 39, as a whole fails to integrate the abstract idea into a practical application. Claim 1 recites the following additional elements, which for the reasons set forth below, do not integrate the abstract idea into a practical application: “…a wearable defibrillator…” which is directed to data gathering, see MPEP 2106.05(g). “…by at least one processor…” which is directed to mere instructions to apply an exception, see MPEP 2106.05(f). “…from a plurality of electrodes…” which is directed to data gathering, see MPEP 2106.05(g). “…at least one motion sensor…” which is directed to data gathering, see MPEP 2106.05(g). Therefore, the claim fails to integrate the abstract idea into a practical application. The examiner also notes that the additional elements recited above do not apply or use the judicial exception to affect a particular treatment or prophylaxis for a disease or medical condition. The above claims are silent to providing any treatment at all to a patient. Step 2B Claim 39 as a whole fails to recite an inventive concept. The additional elements, when considered individually and in combination, do not recite significantly more than the abstract idea for the reasons as set forth above in Step 2A, Prong 2. Upon re-evaluating the limitation that was previously identified as insignificant extra-solution activity in Step 2A, Prong 2, the following evidence to show that the limitation is well-understood, routine and conventional: real-time discrete data obtained from a medical device/data previously collected from a medical device (i.e. body surface/unipolar electrodes) Presenting offers and gathering statistics, OIP Techs., 788 F.3d at 1362-63, 115 USPQ2d at 1092-93; Receiving or transmitting data over a network, e.g., using the Internet to gather data, Symantec, 838 F.3d at 1321, 120 USPQ2d at 1362 (utilizing an intermediary computer to forward information); TLI Communications LLC v. AV Auto. LLC, 823 F.3d 607, 610, 118 USPQ2d 1744, 1745 (Fed. Cir. 2016) (using a telephone for image transmission); OIP Techs., Inc., v. Amazon.com, Inc., 788 F.3d 1359, 1363, 115 USPQ2d 1090, 1093 (Fed. Cir. 2015) (sending messages over a network); buySAFE, Inc. v. Google, Inc., 765 F.3d 1350, 1355, 112 USPQ2d 1093, 1096 (Fed. Cir. 2014) (computer receives and sends information over a network). producing at said computer processor a human-readable output (i.e. processor) of the analysis of the gathered data, this is also WURC, as evidenced by Electric Power Group, LLC v. Alstom S.A., 830F.3d 1350, 119 USPQ2d 1739 (Fed.Cir. 2016), which discusses “conventional computer, network, and display technology” and states that “nothing in the patent contains any suggestion that the displays needed for that purpose are anything but readily available. We have repeatedly held that such invocations of computers and networks that are not even arguably inventive are “insufficient to pass the test of an inventive concept in the application” of an abstract idea”.” Similarly, there is nothing in Applicant’s specification that indicates that the device that is “producing at said computer processor a human-readable output indicating” the findings of the analysis is anything but readily available. The examiner also notes that the limitations of the dependent claims, i.e. claims 40-44, 48, 50, 53, 55-56, 58-60, 62, 67-69 & 71-72, define outputting by the at least one processor, transmitting by the at least one processor, detecting by the at least one processor, recording the wear onset event, notifying the indication of a patient wear compliance, etc., which further limit claim limitations already indicated above as being directed to an abstract idea. Therefore, the above dependent claims are also directed to patient-ineligible subject matter. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 43 & 56 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 43 recites the limitations "the acceptable impedance range" in line 11 and “the impedance level” in line 13. There is insufficient antecedent basis for these limitations in the claim. Claim 56 recites the limitations "the impedance level" in line 3, “the impedance level” in line 5 and “the impedance threshold” in line 5. There is insufficient antecedent basis for these limitations in the claim. 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.
