Office Action

§101 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Response to Arguments Applicant’s arguments combined with the claim amendments have been fully considered and are found persuasive with respect to the previous rejection(s); however, upon further search and consideration due to the change in scope, an updated grounds of rejection is presented below, necessitated by amendment. 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 21-40 are rejected under 35 U.S.C. 101 because the claimed invention is not directed to patent eligible subject matter. Based upon consideration of all of the relevant factors with respect to the claim as a whole, the claims are determined to be directed to a judicial exception, specifically an abstract idea, without significantly more. Step 1 The claimed inventions in claims 21-40 are directed to statutory subject matter as the claim(s) recite(s) a system of a wearable defibrillator. Step 2A, Prong One Claim 21 recites the following steps or instructions to “determine…the identified ECG channel”, “acquire…at least one ECG signal…”, “analyze…the at least one ECG signal”, which is grouped as a mental process in MPEP 2106.04(a)(2)(III) and / or mathematical concept in MPEP 2106.04(a)(2)(I). For example, the limitations concern data collection from ECG signals and data analysis which is directed to mental processes of performing concepts in a human mind or by a human using a pen and paper and mathematical concepts. For example, these limitations are nothing more than a medical professional acquiring an ECG signal, determine a specific ECG channel for consideration and analyzing that ECG signal, using mathematical calculations/concepts. Accordingly, each of the above-identified claims recites an abstract idea as in MPEP 2106.04(a). In addition, Claim 21 recites additional pre and post solution steps involving establishing the set of information for the ECG channels, and storing that information in memory – and the delivery of therapy to the patient, which is a step that occurs independent of the abstract idea. Claim 21 also recites the additional elements of “a plurality of electrodes”, “a control unit”, “a user interface”, “a sensor interface”, “a therapy delivery interface”, “a memory”, and “at least one processor”. Step 2A, Prong Two The above-identified abstract idea in independent Claim 21 (and respective dependent Claims 22-40) is not integrated into a practical application under MPEP 2106.04(d) because the additional elements (identified above in independent Claims X), either alone or in combination, generally link the use of the above-identified abstract idea to a particular technological environment or field of use according to MPEP 2106.05(h) and appear to be extra solution activity where data to be analyzed by the abstract idea is acquired or obtained. More specifically, the additional elements of: “a plurality of electrodes”, “a control unit”, “a user interface”, “a sensor interface”, “a therapy delivery interface”, “a memory”, and “at least one processor” are generically recited computer elements in independent Claim 21 (and respective dependent Claims 22-40) which do not improve the functioning of a computer, or any other technology or technical field according to MPEP 2106.04(d)(1) and 2106.05(a). Nor do these above-identified additional elements serve to apply the above-identified abstract idea with, or by use of, a particular machine according to MPEP 2106.05(b), effect a transformation according to MPEP 2106.05(c), provide a particular treatment or prophylaxis according to MPEP 2106.04(d)(2) or apply or use the above-identified abstract idea in some other meaningful way beyond generally linking the use thereof to a particular technological environment, such that the claim as a whole is more than a drafting effort designed to monopolize the exception according to MPEP 2106.04(d)(2) and 2106.05(e). Furthermore, the above-identified additional elements do not add a meaningful limitation to the abstract idea because they amount to simply implementing the abstract idea on a computer in accordance with MPEP 2106.05(f). For at least these reasons, the abstract idea identified above in independent Claim 21 (and respective dependent Claims 22-40) is not integrated into a practical application in accordance with MPEP 2106.04(d). Moreover, the above-identified abstract idea is not integrated into a practical application in accordance with MPEP 2106.04(d) because the claimed method and system merely implements the above-identified abstract idea (e.g., mental process and using mathematical concepts) using rules (e.g., computer instructions) executed by a computer (e.g., “a plurality of electrodes”, “a control unit”, “a user interface”, “a sensor interface”, “a therapy delivery interface”, “a memory”, and “at least one processor” as claimed). In other words, these claims are merely directed to an abstract idea with additional generic computer elements which do not add a meaningful limitation to the abstract idea because they amount to simply implementing the abstract idea on a computer according to MPEP 2106.05(f). Additionally, Applicant’s specification does not include any discussion of how the claimed invention provides a technical improvement realized by these claims over the prior art or any explanation of a technical problem having an unconventional technical solution that is expressed in these claims according to MPEP 2106.05(a). That is, like Affinity Labs of Tex. v. DirecTV, LLC, the specification fails to provide sufficient details regarding the manner in which the claimed invention accomplishes any technical improvement or solution. Thus, for these additional reasons, the abstract idea identified above in independent Claim 21 (and respective dependent Claims 22-40) is not integrated into a practical application under MPEP 2106.04(d)(I). Accordingly, independent Claim 21 (and respective dependent Claims 22-40) are each directed to an abstract idea according to MPEP 2106.04(d). Step 2B Claim 21 does not include additional elements that are sufficient to amount to significantly more than the abstract idea in accordance with MPEP 2106.05 for at least the following reasons: These claims require the additional elements of: “a plurality of electrodes”, “a control unit”, “a user interface”, “a sensor interface”, “a therapy delivery interface”, “a memory”, and “at least one processor”. The above-identified additional elements are generically claimed computer components which enable the above-identified abstract idea(s) to be conducted by performing the basic functions of automating mental tasks. The courts have recognized such computer functions as well understood, routine, and conventional functions when claimed in a merely generic manner (e.g., at a high level of generality) or as insignificant extra-solution activity. See, MPEP 2106.05(d)(II) along with Versata Dev. Group, Inc. v. SAP Am., Inc., 793 F.3d 1306, 1334, 115 USPQ2d 1681, 1701 (Fed. Cir. 2015); and OIP Techs., 788 F.3d at 1363, 115 USPQ2d at 1092-93. Per Applicant’s specification: “a plurality of electrodes”, “a control unit”, “a user interface”, “a sensor interface”, “a therapy delivery interface”, “a memory”, and “at least one processor” are described in the disclosure as a component that is generic and conventionally used and known in the art: “known ambulatory wearable defibrillators...” [4 – published app]. Accordingly, in light of Applicant’s specification, “a plurality of electrodes”, “a control unit”, “a user interface”, “a sensor interface”, “a therapy delivery interface”, “a memory”, and “at least one processor” and their function are considered well-understood routine and conventional in the art, performing presolution activities that are merely data gathering steps for the abstract idea in Claim 1. Additionally, the claimed terms are reasonably construed as a generic computing device. Like SAP America vs Investpic, LLC (Federal Circuit 2018), it is clear, from the claims themselves and the specification, that these limitations require no improved computer resources, just already available computers, with their already available basic functions, to use as tools in executing the claimed process. See MPEP 2106.05(f). Furthermore, Applicant’s specification does not describe any special programming or algorithms required for “a plurality of electrodes”, “a control unit”, “a user interface”, “a sensor interface”, “a therapy delivery interface”, “a memory”, and “at least one processor”. This lack of disclosure is acceptable under 35 U.S.C. §112(a) since this hardware performs non-specialized functions known by those of ordinary skill in the computer arts. By omitting any specialized programming or algorithms, Applicant's specification essentially admits that this hardware is conventional and performs well understood, routine and conventional activities in the computer industry or arts. In other words, Applicant’s specification demonstrates the well-understood, routine, conventional nature of the above-identified additional elements because it describes these additional elements in a manner that indicates that the additional elements are sufficiently well-known that the specification does not need to describe the particulars of such additional elements to satisfy 35 U.S.C. § 112(a) (see MPEP 2106.05(d)(I)(2) and 2106.07(a)(III)). Adding hardware that performs “‘well understood, routine, conventional activit[ies]’ previously known to the industry” will not make claims patent-eligible (TLI Communications along with MPEP 2106.05(d)(I)). The recitation of the above-identified additional limitations in Claim 21 (and respective dependent Claims 22-40) amounts to mere instructions to implement the abstract idea on a computer. Simply using a computer or other machinery in its ordinary capacity for economic or other tasks (e.g., to receive, store, or transmit data) or simply adding a general-purpose computer or computer components after the fact to an abstract idea (e.g., a fundamental economic practice or mathematical equation) does not provide significantly more. See MPEP 2106.05(f) along with Affinity Labs v. DirecTV, 838 F.3d 1253, 1262, 120 USPQ2d 1201, 1207 (Fed. Cir. 2016) (cellular telephone); and TLI Communications LLC v. AV Auto, LLC, 823 F.3d 607, 613, 118 USPQ2d 1744, 1748 (Fed. Cir. 2016) (computer server and telephone unit). Moreover, implementing an abstract idea on a generic computer, does not add significantly more, similar to how the recitation of the computer in the claim in Alice amounted to mere instructions to apply the abstract idea of intermediated settlement on a generic computer. A claim that purports to improve computer capabilities or to improve an existing technology may provide significantly more. See MPEP 2106.05(a) along with McRO, Inc. v. Bandai Namco Games Am. Inc., 837 F.3d 1299, 1314-15, 120 USPQ2d 1091, 1101-02 (Fed. Cir. 2016); and Enfish, LLC v. Microsoft Corp., 822 F.3d 1327, 1335-36, 118 USPQ2d 1684, 1688-89 (Fed. Cir. 2016). However, a technical explanation as to how to implement the invention should be present in the specification for any assertion that the invention improves upon conventional functioning of a computer, or upon conventional technology or technological processes. That is, per MPEP 2106.05(a), the disclosure must provide sufficient details such that one of ordinary skill in the art would recognize the claimed invention as providing an improvement. Here, Applicant’s specification does not include any discussion of how the claimed invention provides a technical improvement realized by these claims over the prior art or any explanation of a technical problem having an unconventional technical solution that is expressed in these claims. Instead, as in Affinity Labs of Tex. v. DirecTV, LLC 838 F.3d 1253, 1263-64, 120 USPQ2d 1201, 1207-08 (Fed. Cir. 2016), the specification fails to provide sufficient details regarding the manner in which the claimed invention accomplishes any technical improvement or solution. For at least the above reasons, the system of Claim 21 (and respective dependent Claims 22-40) are directed to applying an abstract idea as identified above on a general purpose computer without (i) improving the performance of the computer itself or providing a technical solution to a problem in a technical field according to MPEP 2106.05(a), or (ii) providing meaningful limitations to transform the abstract idea into a patent eligible application of the abstract idea such that these claims amount to significantly more than the abstract idea itself according to MPEP 2106.04(d)(2) and 2106.05(e). Taking the additional elements individually and in combination, the additional elements do not provide significantly more. Specifically, when viewed individually, the above-identified additional elements in independent Claim 21 (and respective dependent Claims 22-40) do not add significantly more because they are simply an attempt to limit the abstract idea to a particular technological environment according to MPEP 2106.05(h). When viewed as a combination, these above-identified additional elements simply instruct the practitioner to implement the claimed functions with well-understood, routine and conventional activity specified at a high level of generality in a particular technological environment according to MPEP 2106.05(h). When viewed as whole, the above-identified additional elements do not provide meaningful limitations to transform the abstract idea into a patent eligible application of the abstract idea such that the claims amount to significantly more than the abstract idea itself according to MPEP 2106.04(d)(2) and 2106.05(e). Moreover, neither the general computer elements nor any other additional element adds meaningful limitations to the abstract idea because these additional elements represent insignificant extra-solution activity according to MPEP 2106.05(g). As such, there is no inventive concept sufficient to transform the claimed subject matter into a patent-eligible application as required by MPEP 2106.05.
