Eich et al teaches wherein the second magnetic element magnetically couples with the first magnetic element to hold the disposable portion to the reusable portion before a securing mechanism (threads) secures the disposable portion in the reusable portion (Figure 1)(paragraph [0027]). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the second magnetic element, of the modified device of Elahi et al and Eich et al, to magnetically couple with the first magnetic element to hold the disposable portion to the reusable portion before the securing mechanism secures the disposable portion in the reusable portion, as taught by Eich et al, as such will allow for various types of disposable portions to be automatically recognized and differentiated by the reusable portion, and will minimize incorrect or erroneous recognition and/or use of disposable portions (paragraph [0007]). In regards to claim 21, in the modified device of Elahi et al and Eich et al, Elahi et al does not teach wherein the reusable portion further comprises a sensor configured to detect the second magnetic element and thereby detect disposition of the disposable unit in the reusable portion. Eich et al teaches wherein the reusable portion further comprises a sensor (3) configured to detect the second magnetic element and thereby detect disposition of the disposable unit in the reusable portion (Figure 1). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the reusable portion, of the modified device of Elahi et al and Eich et al, to further comprise a sensor, as taught by Eich et al, as such will allow for various types of disposable portions to be automatically recognized and differentiated by the reusable portion, and will minimize incorrect or erroneous recognition and/or use of disposable portions (paragraph [0007]). In regards to claim 22, Elahi et al does not teach wherein the reusable portion further comprises a sensor configured to detect disposition of the disposable unit in the reusable portion. Eich et al teaches a therapeutic agent delivery device (Figures 1-3) wherein a reusable portion (6) further comprises a sensor (3) configured to detect disposition of a disposable unit (1) in the reusable portion (Figure 1). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the reusable portion, of the device of Elahi et al, to further comprise a sensor, as taught by Eich et al, as such will allow for various types of disposable portions to be automatically recognized and differentiated by the reusable portion, and will minimize incorrect or erroneous recognition and/or use of disposable portions (paragraph [0007]). In regards to claim 23, in the modified device of Elahi et al and Eich et al, Elahi et al does not teach wherein upon the sensor detecting disposition of the disposable unit in the reusable portion, the securing mechanism is actuated to move the protrusion relative to the track and thereby secure the disposable portion in the reusable portion. Eich et al teaches wherein upon the sensor detecting disposition of the disposable unit in the reusable portion, a securing mechanism (threads) is actuated to move a protrusion (of threads of 1) relative to a track (of threads of 6) and thereby secure the disposable portion in the reusable portion (Figure 1). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the modified device, of Elahi et al and Eich et al, to upon the sensor detecting disposition of the disposable unit in the reusable portion, the securing mechanism is actuated to move the protrusion relative to the track and thereby secure the disposable portion in the reusable portion, as taught by Eich et al, as such will allow for various types of disposable portions to be automatically recognized and differentiated by the reusable portion, and will minimize incorrect or erroneous recognition and/or use of disposable portions (paragraph [0007]). In regards to claim 24, in the modified device of Elahi et al and Eich et al, Elahi et al does not teach wherein the sensor is a magnetic field sensor. Eich et al teaches wherein the sensor is a magnetic field sensor (3). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the sensor, of the modified device of Elahi et al and Eich et al, to be a magnetic field sensor, as taught by Eich et al, as such will allow for various types of disposable portions to be automatically recognized and differentiated by the reusable portion, and will minimize incorrect or erroneous recognition and/or use of disposable portions (paragraph [0007]). Claim 25 is rejected under 35 U.S.C. 103 as being unpatentable over Elahi et al, as applied to claim 9 above, and further in view of Adams et al (US 2012/0323177). In regards to claim 25, Elahi et al teaches wherein the first housing comprises a distal end (Figure 4), the securing mechanism is configured to release the disposable portion and thereby permits the disposable portion to be detached from the reusable portion (Figure 4). However, Elahi et al is silent about the syringe assembly is translatable relative to the first housing from a stowed configuration to a deployed configuration and back to the stowed configuration, in the stowed configuration the needle being disposed proximally relative to the distal end of the first housing, in the deployed configuration the needle is at least partially extended distally from the distal end of the first housing and the therapeutic agent can be delivered, and wherein upon the syringe assembly is translated from the deployed configuration back to the stowed configuration. Adams et al teaches a therapeutic agent delivery device (Figures 1-19) wherein a first housing (50) comprises a distal end, a syringe assembly (110) is translatable relative to the first housing from a stowed configuration (Figures 14-16) to a deployed configuration (Figures 17-18) and back to the stowed configuration (Figure 19), in the stowed configuration a needle (114) being disposed proximally relative to the distal end of the first housing (Figures 14-16, 19), in the deployed configuration the needle is at least partially extended distally from the distal end of the first housing and a therapeutic agent can be delivered (Figures 17-18), and wherein upon the syringe assembly is translated from the deployed configuration back to the stowed configuration (Figures 17-19). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the syringe assembly, of the device of Elahi et al, to be translatable relative to the first housing from a stowed configuration to a deployed configuration and back to the stowed configuration, as taught by Adams et al, as such will provide the needle between a protected position and an injection position for delivering the therapeutic agent to a user (paragraphs [0070][0073]), wherein the protected position would prevent an accidental needlestick to the user. Allowable Subject Matter Claim 15 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. In regards to claim 15, the prior art of record does not disclose or render obvious before the effective filing date of the claimed invention the combination of a therapeutic agent delivery device, as claimed, specifically including wherein the securing mechanism further comprises a rotary actuator, the rotary actuator being actuatable to rotatably drive the cylinder relative to the second housing, the rotary actuator is configured to actuate the securing mechanism and whereby the disposable portion is secured to the reusable portion. Elahi et al teaching a securing mechanism (128/108); however, Elahi et al does not teach wherein the securing mechanism further comprises a rotary actuator, the rotary actuator being actuatable to rotatably drive the cylinder relative to the second housing, the rotary actuator is configured to actuate the securing mechanism and whereby the disposable portion is secured to the reusable portion. Thus, claim 15 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim 9 and intervening claim 10. Claim 28 is allowed. In regards to claim 28, the prior art of record does not disclose or render obvious before the effective filing date of the claimed invention the combination of a therapeutic agent delivery device, as claimed, specifically including a rotary actuator, the rotary actuator actuatable to rotatably drive the cylinder relative to the second housing to secure the disposable portion to the reusable portion. Elahi et al teaches a therapeutic agent delivery device (Figures 1-4), comprising: a disposable portion (124), comprising a first housing (102), a therapeutic agent container assembly (cartridge) carried by the first housing (column 7, lines 27-28) a reusable portion (122) is configured to detachably carry the disposable portion, the reusable portion comprising a second housing (110), a securing mechanism (128) carried in the second housing, a cylinder (108) configured to detachably receive the disposable portion and rotate relative to the second housing to actuate the securing mechanism and thereby secure the disposable portion to the reusable portion (column 8, lines 41-48) wherein one of the disposable portion and the securing mechanism comprises a track (128), the other of the disposable portion and the securing mechanism comprises a protrusion (126) being movable along the track, and wherein the securing mechanism is actuatable to move the protrusion along the track and thereby secure the disposable portion to the reusable portion (column 9, lines 5-9) Elahi et al does not teach a rotary actuator, the rotary actuator actuatable to rotatably drive the cylinder relative to the second housing to secure the disposable portion to the reusable portion. Thus, claim 28 is allowed.
