It would have been obvious to one of ordinary skill in the art before the effective filing date to modify the dose determination unit of Blei such that the dose is determined based on the determined type of the injection device as taught by Chen in order to deliver an appropriate dose based on collected information while relieving a user from manually recording injection and medicament information (Chen: para. 0019 and 0047-0048). Regarding claim 31, Blei teaches the system above, wherein the supplemental device (Blei: Fig. 2a, device 2) further comprises a dose determination unit (processor 24 may constitute a dose delivery determiner; para. 0057) wherein the processor (Fig. 3, processor 24) is further configured to cause the supplemental device (Fig. 2a, supplemental device 2) to determine a dose of medicament contained in the injection device (Fig. 1a, drug delivery device 1) by using the dose determination unit (dose delivery determiner determines dose of medicament quantity; para. 0057). Blei does not expressly disclose that the dose is determined based on the determined type of the injection device. Chen teaches a device (Chen: Fig. 7, injection device 700), wherein a dose is determined based on the determined type of the injection device (Fig. 9, medicament information, which includes medicament type, is received at process block 906, which is then used to determine dose at process block 908; para. 0047-0048). It would have been obvious to one of ordinary skill in the art before the effective filing date to modify the dose determination unit of Blei such that the dose is determined based on the determined type of the injection device as taught by Chen in order to deliver an appropriate dose based on collected information while relieving a user from manually recording injection and medicament information (Chen: para. 0019 and 0047-0048). Regarding claim 35, Blei teaches the method above. Blei does not expressly disclose that the dose is determined based on the determined type of the injection device. Chen teaches a device (Chen: Fig. 7, injection device 700), wherein a dose is determined based on the determined type of the injection device (Fig. 9, medicament information, which includes medicament type, is received at process block 906, which is then used to determine dose at process block 908; para. 0047-0048). It would have been obvious to one of ordinary skill in the art before the effective filing date to modify the dose determination unit of Blei such that the dose is determined based on the determined type of the injection device as taught by Chen in order to deliver an appropriate dose based on collected information while relieving a user from manually recording injection and medicament information (Chen: para. 0019 and 0047-0048). Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over Blei in view of Okamura et al. (US Patent Publication No. 20190091406 A1), hereinafter Okamura. Regarding claim 21, Blei discloses the supplemental device above. Blei does not expressly disclose that the sensor arrangement comprises a navigation switch movable between a plurality of positions, wherein the navigation switch is arranged to be biased into a position of the plurality of positions by a biasing feature of the injection device when the supplemental device is coupled to the injection device, wherein each position in the plurality of positions corresponds to a respective type of injection device, and wherein the processor is configured to determine the type of the injection device based on the position of the navigation switch. Okamura teaches a sensor arrangement (Okamura: Fig. 10, first identification information detector 28) comprises a navigation switch (Fig. 10, minute button 28a is a switch; para. 0275) movable between a plurality of positions (button 28a can be moved from either pressed or not pressed, or a multitude of positions based on the number of identifying information; para. 0275-0277), wherein the navigation switch (Fig. 10, button 28a) is arranged to be biased into a position of the plurality of positions (para. 0275-0277) by a biasing feature (Fig. 3C-D, first identification information 104g) of an injection device (Fig. 2B, 3A-D, cartridge adapter 101) when a supplemental device (Fig. 2B, drug injection device 11) is coupled to the injection device (information 104g biases the button 28a when the adapter 101 is inserted; para. 0275), wherein each position in the plurality of positions (para. 0275-0277) corresponds to a respective type of injection device (button 28a can be moved from either pressed or not pressed, or a multitude of positions based on the number of identifying information, which sends an output signal that determines the type of cartridge adapter; para. 0275-0277), and wherein a processor (Fig. 1, arithmetic circuit 41) is configured to determine the type of the injection device (Fig. 2B, adapter 101) based on the position of the navigation switch (circuit 41 receives output signals from the detector 28, determining which type of cartridge was inserted; para. 0270 and 0275-0277). It would have been obvious to one of ordinary skill in the art before the effective filing date to modify the device of Blei such that the sensor arrangement comprises a navigation switch movable between a plurality of positions, wherein the navigation switch is arranged to be biased into a position of the plurality of positions by a biasing feature of the injection device when the supplemental device is coupled to the injection device, wherein each position in the plurality of positions corresponds to a respective type of injection device, and wherein the processor is configured to determine the type of the injection device based on the position of the navigation switch as taught by Okamura in order to allow for a multitude of different types of drug injectors and for easy switching between injectors through mechanical detection (para. 0069-0070 and 0275-0277).
