Regarding claim 19, Dalforno teaches the invention as claimed and discussed above and Dalforno further teaches the user interface is part of an ambulatory infusion pump containing the pump mechanism (The interface can be output on many different receiver devices, such as 111-113. One example is 111, which is a dedicated medical device. A pump, which is discussed, is a dedicated medical device). Regarding claim 20, Dalforno teaches the invention as claimed and discussed above and Dalforno further teaches the user interface is part of a remote control device (The interface can be output on many different receiver devices, such as 111-113. Each of the devices is a remote control device). Claim Rejections - 35 USC § 103 Claims 4, 5, 12 and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Dalforno (US 20170185953) in view of Alles (US 20240148971). Regarding claims (4,5) and (12,13), Dalforno teaches the invention as discussed above for claims 1 and 11. Claims (4 and 5) depend from claim 1 and claims (12 and 13) depend from claim 11. As discussed above, Dalforno teaches the system is configured for different types of sensors to be used. Dalforno doesn’t teach the stored characteristics include an activation protocol required to activate each of the plurality of types of sensors for use with the system, and wherein configuring the system to interface with the type of sensor based on the stored characteristics includes activating the type of sensor according to the corresponding activation protocol and the at least one processor is further configured to provide instructions to the user to guide the user through one or more steps of the activation protocol. Alles teaches a wearable ambulatory infusion pump system (200, Fig, 2) including a pump 204, a CGM 206 and a smartphone 200 similar to Dalforno. In Figs. 5-7, Alles teaches an activation protocol required to activate a sensors for use with the system and the at least one processor is further configured to provide instructions to the user to guide the user through one or more steps of the activation protocol. The proposed modification to Dalforno is to provide an application protocol taught by Alles for each of the types of sensors taught by Dalforno so that each of sensors can be configured for use when they are replaced. As discussed above, Dalforno teaches a system configurable to operate with different types of sensors and storing characteristics for each of the types of sensors. Alles is being relied upon to teach the characteristics stored for each type of sensor include an activation protocol. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to make the systems of Dalforno in claims 1 and 11 have the stored characteristics include an activation protocol required to activate each of the plurality of types of sensors for use with the system, and wherein configuring the system to interface with the type of sensor based on the stored characteristics includes activating the type of sensor according to the corresponding activation protocol and the at least one processor is further configured to provide instructions to the user to guide the user through one or more steps of the activation protocol, as taught by Alles, in order to allow a user of the system Dalforno to activate a new type of sensor after ordering a replacement. Claims 6, 7, 8, 14, 15 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Dalforno (US 2017/0185953) in view of Strickland (US 2012/0165614). Regarding claims (6, 7, 8) and (14, 15, 16), Dalforno teaches the invention as discussed above for claims 1 and 11. Claims (6, 7 and 8) depend from claim 1 and claims (14, 15 and 16) depend from claim 11. As discussed above, Dalforno teaches the system is configured for different types of sensors to be used and hence, communication with different types of sensors. Dalforno doesn’t teach the stored characteristics include a communication protocol employed by each of the plurality of types of sensors to transmit data to the communications interface, and wherein configuring the system to interface with the type of sensor based on the stored characteristics includes configuring the communications interface to communicate with the type of sensor according to the corresponding communication protocol, the stored characteristics include a type of data transmitted by each of the plurality of types of sensors to the communications interface, and wherein configuring the system to interface with the type of sensor based on the stored characteristics includes processing the data based on the type of data transmitted by the type of sensor, the stored characteristics include one or more authentication protocols required by each of the plurality of types of sensors, and wherein configuring the system to interface with the type of sensor based on the stored characteristics includes implementing the one or more authentication protocols required by the type of sensor. Strickland teaches a wearable ambulatory infusion pump system ( Fig, 2) including a pump 204, a CGM 200 and a handheld device 104 similar to Dalforno. Strickland teaches the devices can use different communication protocols including open protocols (¶25) and proprietary protocols (¶26). Strickland teaches different devices can communicate different types of data (Fig. 6 teaches the use of a standard communication extension with a first types of data and Fig. 7 teaches the use of a private extension that sends different types of data as compared to the standard extension. Figs. 6 and 7, show how each extension is implemented to allow proper communications of data). Strickland teaches the use of some functions, such as upgrading firmware on a device (¶66) require additional security verifications, which is discussed with respect to Fig. 8. The proposed modification to Dalforno is to provide communication protocols, data types and authentication protocols for each of the types of sensors taught by Dalforno so that each of different types of sensors can be configured for use when they are replaced. As discussed above, Dalforno teaches a system configurable to operate with different types of sensors and storing characteristics for each of the types of sensors. Strickland is being relied upon to teach the characteristics stored for each type of sensor include communication protocols, authentication protocols and data types. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to make the system Dalforno in claims 1 and 11 have the stored characteristics include a communication protocol employed by each of the plurality of types of sensors to transmit data to the communications interface, and wherein configuring the system to interface with the type of sensor based on the stored characteristics includes configuring the communications interface to communicate with the type of sensor according to the corresponding communication protocol, the stored characteristics include a type of data transmitted by each of the plurality of types of sensors to the communications interface, and wherein configuring the system to interface with the type of sensor based on the stored characteristics includes processing the data based on the type of data transmitted by the type of sensor, the stored characteristics include one or more authentication protocols required by each of the plurality of types of sensors, and wherein configuring the system to interface with the type of sensor based on the stored characteristics includes implementing the one or more authentication protocols required by the type of sensor, as taught by Strickland, in order to allow the sensors to operate properly in the system, i.e., establish communications, communicate sensor specific data and operate securely. Claims 9, 10, 17 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Dalforno (US 2017/0185953) in view of Mastrototaro (US 2007/0100222). Regarding claims 9, 10, 17 and 18, Dalforno teaches the invention as discussed above for claims 1 and 11. Claim 9 and 10 depend from claim 1 and claims 17 and 18 depend from claim 11. As discussed above, Dalforno teaches the system is configured for different types of sensors to be used and hence, communication and operation of the system with different types of sensors. Dalforno doesn’t teach the stored characteristics include a warmup period required by each of the plurality type of sensors following insertion before the type of sensor can reliably transmit data, and wherein configuring the system to interface with the type of sensor includes coordinating communications with the type of sensor according to the warmup period and the stored characteristics include a time interval between communications of data indicative of a glucose level for each type of sensor, and wherein configuring the system to interface with the type of sensor includes coordinating communications with the type of sensor based on the time interval. Mastrototaro teaches a system for monitoring glucose and delivering insulin (Fig. 1A-H, ¶70-¶73). In ¶73, it is taught the sensor may preferably be a real-time sensor. As used herein, the terms "real-time" and "real-time sensor" refer to a sensor that senses values substantially continuously over an extended period of time and makes such values available for use as the values are being sensed and collected rather than having to download substantially all the collected values at a later time for use. For example, a real-time blood glucose sensor might sense glucose values every 10 seconds over an extended period of 24 hours, and make the values available (e.g., processing, charting and displaying) every 5 minutes so that that users of an insulin pump have the flexibility to fine-tune and start or stop insulin delivery upon demand. Patients may thus use their pumps to make substantially immediate therapy adjustments based upon real-time continuous glucose readings displayed every 5 minutes and by viewing a graph with 24-hour glucose trends. Thus, it is important to know when the time interval for communications of data to know when data can be output to a user. In ¶111, it is taught It is possible that a sensor will need to receive regulated power for a defined duration before it can generate a stable signal, in other words it must warm up. And, if regulated power is removed from the sensor, the sensor must warm up again when the power is restored before measurements can be used. Alternatively, it is possible that each time the sensor is warmed up, new reference measurements must be input and paired with a processed sensor signal to create new reference values, which are stored in the reference memory. Reference values are needed to calibrate the processed sensor signal into sensor measurements. Furthermore, periodic reference values may be needed, and if a stable (warmed up) processed sensor signal is not available when a new reference values is needed, then a new reference measurement may have to be collected when the processed sensor signal is available and stable. In the mean time the processed sensor signal cannot be used to generate a sensor measurement. Thus, the warm up characteristics are needed to use the sensor properly in the system. The proposed modification to Dalforno is to provide time interval and warm up data for each of the types of sensors taught by Dalforno so that each of different types of sensors can be configured for use when they are replaced. As discussed above, Dalforno teaches a system configurable to operate with different types of sensors and storing characteristics for each of the types of sensors. Mastrototaro is being relied upon to teach the characteristics stored for each type of sensor include warm up data and time interval data because this data is needed to properly use a particular sensor in the system. With respect to claims 9 and 17, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to make the system of Dalforno of claims 1 and 11 have a warmup period required by each of the plurality type of sensors following insertion before the type of sensor can reliably transmit data, and wherein configuring the system to interface with the type of sensor includes coordinating communications with the type of sensor according to the warmup period, as taught by Mastrototaro, in order to know when the data from the sensor can be reliably used. With respect to claims 10 and 18, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to make the system of Dalforno of claims 1 and 11 have the stored characteristics include a time interval between communications of data indicative of a glucose level for each type of sensor, and wherein configuring the system to interface with the type of sensor includes coordinating communications with the type of sensor based on the time interval., as taught by Mastrototaro, in order to properly utilize and output the data from the sensor.
