This communication is in response to the amendment filed 9/4/25. Claims 1-16 are pending. 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 15-16 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 15 has been amended to further Similarly, claim 15 has been amended to cancel its dependence from claim 1, and further to recite: “wherein the consumer electronic device is configured to…” As drafted, it is unclear whether the recited “consumer electronic device” is an integral component of the recited system, as it is never claimed as a system component. In particular, the antecedent basis for a “consumer electronic device” is an intended use clause describing the communication module a communications module including at least a short range wireless communications capability for communication with a consumer electronic device including any one or more of a smartphone…” Therefore it is unclear how the additional functionalities recited in wherein clause “wherein the consumer electronic device is configured to” further defines the Applicant’s inventive system. It is not clear whether the recited functions further define the functions of the inventive system because it is not clear whether the “consumer electronic device” is a required, integral component of the inventive system. (i.e. a medical device and secure control system comprising: 1) a wearable medical device; 2) a consumer electronic device including any one or more of a smartphone, a personal computer, a smartwatch and a computer tablet; AND 3) a medical device component comprising i) a communications module…, ii) a memory…and iii) a processor…) Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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) 1-14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Spencer et al (US 9980140 B1) in view of Dicks et al (US 20150169314 A1), and in further view of Abrahamsson et al (US 20210035670 A1) Claim 1 Spencer teaches medical device and secure control system comprising: a wearable medical device comprising a pump configured to inject insulin into a user and (col. 16, lines 19-29: The device can include one or more additional components that implement these features, such as a drug delivery system 226 (e.g., insulin pump); Fig. 9A-C) a medical device controller, (col. 16, lines 47-60) i) comprising a communications module including at least a short range wireless communications capability for communication with a consumer electronic device (col. 40, lines 1-15) including any one or more of a smartphone, a personal computer, a smartwatch and a computer tablet, ( col. 16, lines 47-60; fig. 1) ii) a memory (col. 16, line 34-col. 17, line 67) configured to store a computer program and encryption keys configured to establish an encrypted communication with the consumer electronics device (col. 14, lines 10-col. 15, lines 47; col. 16, line 34-col. 17, line 67) and iii) a processor configured to execute the computer program, wherein the medical device controller and the medical device are configured to each store at least one journal for exchange of journal entries between the medical device controller and the consumer electronic device and between the medical device controller and the medical device, the journal entries comprising user identification, user rights, and operations instructed to the medical device, (Fig. 2-instruction sets; col. 14, lines 11-57: the processors 208 and the encryption chipsets 209 can be programmed to encrypt and to store the following as encrypted data 211: patient dosage parameters and models, patient data (e.g., sensor readings, medicine dosing log), keys for authentication and encryption, policies governing commands to which the device 206 responds, firmware and/or instructions that are executed by the device 206 (e.g., the instruction sets 212), and/or other appropriate information; col. 16, line 47-col. 17, line 30: the device controller application 252 can be programmed to use the processors 230 and the encryption chipsets 232 to encrypt all data that is stored locally by the device controller application 252 and to store it as encrypted data 246, and can be programmed to encrypt all packets that are transmitted to the device 206 and/or the computer system 202. Furthermore, the device controller application 252 can be configured to establish a secure network connection, such as a BLE connection using AES in GCM mode) and wherein the medical device controller is configured to provide encrypted communications to a consumer electronic device and receive information from a consumer electronic device.
