Claim(s) 1-6, 9, 11-12, 14-17, 19-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Henderson et al. (US Pub No. 2015/0297833 A1) in view of Watts et al. (US Pub No. 2020/0030540 A1).
Regarding claim 1, Henderson discloses an auto-injector (autoinjector 1, Fig. 1) comprising:
a housing (case 2, Fig. 1) for receiving a syringe (syringe 6, Fig. 1) (“… a syringe carrier in the case 2 that is adapted to hold a syringe 6 …” – Para [0109]) having a barrel (body 20, Fig. 5) containing a medicament (“… the syringe 6 includes a body 20 containing a medicament …” – Para [0127]), a plunger (plunger 10, Fig. 1) and a needle (needle 22, Fig. 6);
a plunger driver (trigger button beams 16, Fig. 3) configured to act on the syringe plunger to move the syringe plunger through the housing (“… the trigger button beams 16 move distally relative to the case 2, and deflect the tongues 15. When the tongues 15 are deflected, the hook 15.1 disengages the ratchet faces 10.5 of the legs 10.2, and the plunger 1, under the force of the drive springs 9, moves distally relative to the case 2.” – Para [0138]) during a needle insertion phase (Fig. 12) and injection phase (Fig. 13);
a safety shroud (interlock sleeve 17, Fig. 1); and
a plunger driver latch (interlock beams 17.1, Fig. 1) coupled to said safety shroud (“… two interlock beams 17.1 extend in the proximal direction from the distal end of the interlock sleeve 17.” – Para [0121]) and moveable between first (“… the interlock sleeve 17 is in the extended position …” – Para [0121]) and second positions (“… the interlock sleeve 17 is in the retracted position …” – Para [0121]) and configured to:
while in the first position before the needle insertion phase, latch the plunger driver at a pre-insertion position in the housing (“… when the interlock sleeve 17 is in the extended position, the trigger button may be locked and prevented from actuation.” – Para [0121]),
move to the second position (“When the interlock sleeve 17 moves from the extended position to the retracted position, the proximal ends of the interlock beams 17.1 cause the button locking beams 18 to deflect.” – Para [0121]) as a result of pressure applied to the safety shroud (“When the autoinjector 1 is placed on the injection site, interlock sleeve 17 may be pushed int the proximal direction into a retracted position …” – Para [0119]), to unlatch the plunger driver from the pre-insertion position (“When the button locking beams 18 are deflected, the trigger buttons 16 may move in the distal direction.” – Para [0122]) and allow forward movement of the plunger driver to a post-insertion and injection position in the housing (“… the trigger button beams 16 move distally relative to the case 2 …” – Para [0138]), and
return to the first position upon removal or reduction of pressure on the safety shroud (“… the interlock sleeve 17 returns to the extended state under the force of the spring …” – Para [0141]), wherein the auto-injector comprises a biasing member configured to bias the plunger driver latch towards the first position (“The interlock sleeve 17 may be biased by a spring in an extended position …” – Para [0119]).
Henderson does not expressly disclose that the plunger driver latch is configured to latch the plunger driver at the post-insertion and injection position and to unlatch the plunger driver from the post-insertion and injection position and allow forward movement of the plunger driver to deploy the safety shroud,
Watts teaches that the plunger driver latch is configured to latch the plunger driver at the post-insertion and injection position (“The safety plunger 206 is coupled to a syringe plunger 222 during a first part of its inward stroke.” – Para [0053]) and to unlatch the plunger driver from the post-insertion and injection position and allow forward movement of the plunger driver to deploy the safety shroud (“After decoupling, the safety plunger may move longitudinally relative to the syringe plunger 222 and continued movement of the safety plunger 206 moves the sheath 214 into a position covering the needle.” – Para [0053]).
Therefore, it would have been obvious, before the effective filing date of the claimed invention, to modify the auto-injector of Henderson to include latching the plunger driver at the post-insertion and injection position and unlatching the plunger driver from the post-insertion and injection position and allow forward movement of the plunger driver to deploy the safety shroud as taught by Watts so that the syringe plunger 222 has expelled all of a medicament or drug from the barrel 214 (Watts, Para [0053]).
Examiner interprets the interlocks beams 17.1 as being connected to interlock sleeve 17. Thus, as interlock sleeve 17 moves from an extended to a retracted position or is biased by a spring, so is the interlock beams 17.1.
Regarding claim 2, Henderson discloses the auto-injector (autoinjector 1, Fig. 1) as recited above, wherein
before deployment of the safety shroud (Fig. 13), the safety shroud is moveable between an extended position and a retracted position in the housing (“an interlock sleeve slidably disposed in the case and having an extended position and a retracted position relative to the case.” – Para [0009]) as a result of said applying, or removal or reduction of pressure (“When the autoinjector 1 is placed on the injection site, interlock sleeve may be pushed in the proximal direction into a retracted position …” – Para [0119]).
Regarding claim 3, Henderson discloses the auto-injector (autoinjector 1, Fig. 1) as recited above, wherein
before deployment of the safety shroud (Fig. 13), movement of the safety shroud (interlock sleeve 17) from the extended position to the retracted position moves the plunger driver latch (interlock beams 17.1) from the first position to the second position (“When the interlock sleeve 17 moves from the extended position to the retracted position, the proximal ends of the interlock beams 17.1 cause the button locking beams 18 to deflect.” – Para [1021]) to unlatch the plunger driver from the pre-insertion position (“When the button locking beams 18 are deflected, the trigger buttons beams 16 may move in the distal direction.” – Para [0122]).
Regarding claim 4, Henderson discloses the auto-injector (autoinjector 1, Fig. 1) as recited above, wherein
movement of the safety shroud from the retracted position to the extended position (“… the interlock sleeve 17 returns to the extended state under the force of the spring …” – Para [0141]) returns the plunger driver latch to the first position (“the interlock sleeve 17 returns to the extended state under the force of the spring …” – Para [0141])
Henderson does not expressly disclose to unlatch the plunger driver from the post-insertion and injection position
Watts teaches to unlatch the plunger driver from the post-insertion and injection position (“The safety plunger 206 decouples from the syringe plunger 222 at a point on the inward stroke, which may be when the syringe plunger has expelled all of a medicament or drug from the barrel 214.” – Para [0053]). B
Therefore, it would have been obvious, before the effective filing date of the claimed invention, to modify the auto-injector of Henderson to include to unlatch the plunger driver from the post-insertion and injection position as taught by Watts so the safety plunger 206 moves the sheath 214 into a position covering the needle (Watts, Para [0053]).
Examiner interprets the interlocks beams 17.1 as being connected to interlock sleeve 17. Thus, as interlock sleeve 17 moves from a retracted to an extended position, so do the interlock beams 17.1.
Regarding claim 5, Henderson discloses the auto-injector (autoinjector 1, Fig. 1) as recited above, wherein
the safety shroud (interlock sleeve 17, Fig. 3) comprises a first angled cam surface configured to engage a second angled cam surface of the plunger driver (resilient button locking beams 18, Fig. 3) (“Proximal ends of the interlock beams 17.1 include ramped surfaces which engage with corresponding ramped surfaces of resilient button locking beams 18 disposed in the case 2.” – Para [0121]) to move the plunger driver latch to the second position when the safety shroud is moved to the retracted position (“When the interlock sleeve moves from the extended position to the retracted position, the proximal ends of the interlock beams 17.1 cause the button locking beams 18 to deflect.” – Para [0121]).
Examiner interprets the interlock beams 17.1 to be connected to the interlock sleeve 17, and thus the ramped surfaces of 17.1 to be part of interlock sleeve 17.
Regarding claim 6, Henderson discloses the auto-injector (autoinjector 1, Fig. 1) as recited above, wherein
wherein the plunger driver latch (pivoted clip 21.1) comprises a pivot (See annotated Fig. 16)

wherein the plunger driver latch is rotatable about the pivot to move between the first position (Fig. 16) and the second position (Fig. 17) (“… a pivoted clip 21.1 on the case 21 which in a non-deflected position engages a recess in the needle shield 21 and in deflected position disengages the recess in the needle shield 23.” – Para [0125])
Regarding claim 9, Henderson discloses the auto-injector (autoinjector 1, Fig. 1) as recited above, wherein
the biasing member comprises a spring (“The interlock sleeve 17 may be biased by a spring in an extended position …” – Para [0119]).

the auto-injector comprises an openable lid (door 3, Fig. 1) to allow insertion and removal of the syringe (“In the open position, the door 3 provides access to a syringe carrier in the case 2 that is adapted to hold a syringe 6 …” – Para [0109]), wherein the lid is configured to hinge between an open position and a closed position (“… the door 3 may be formed on a side of the case 2 and rotate about a transverse hinge between the open and closed positions.” – Para [0109]).
Regarding claim 15, Henderson discloses the auto-injector (autoinjector 1, Fig. 1) as recited above, wherein
the lid (door 3, Fig. 3) is configured on a closing movement thereof to prime a drive spring (drive spring 9, Fig. 1) of the plunger driver (trigger button beams 16, Fig. 3)(“… the drive springs have been compressed … and the door 3 is being closed.” – Para [0116]).
Regarding claim 16, Henderson discloses the auto-injector (autoinjector 1, Fig. 1) as recited above, wherein
in combination with a syringe (syringe 6, Fig. 1) comprising a syringe safety shroud (needle shield 23, Fig. 19) configured to cover a needle of the syringe when in a closed position (“… the syringe 6 with the needle shield 23 in an extended position, covering a distal tip of the needle 22.” – Para [0125]).
