Regarding Claims 9 and 16, Cronenberg in view of Zhang Li teaches the claimed invention as discussed above. Cronenberg further discloses in Figs. 5-7, the injector button 10 being mechanically connected to the pen body 2+3+6+10 (it is a portion of the pen body); the injector button 10 compressing when receiving an external surface force (read, e.g. para. 0073); and the injector button releasing the liquid medication from the medication cartridge when the injector button is compressed (read e.g. para. 0073). Regarding Claim 17, Cronenberg discloses in Figs. 5-7, more detailed explanations found in the rejections of the same limitations found above, an insulin self-injection pen comprising: a needle 151; a medication cartridge 4; a pen body 2+3+6+10; the medication cartridge 4 comprising a dose adjustor 44; the pen body comprising an outer casing 2+3, a dose adjustment dial 6 and an injector button 10; the needle 151 securing to the distal end 45 of the medication cartridge 151; the medication cartridge 4 being positioned within the pen body 2+3+6+10; the pen body 2+3+6+10 encompassing around the medication cartridge 4 and needle 151 (when the needle pierces the distal end 45 as described in para. 0091, the pen body encompasses the needle in the same way shown by the instant application figures); the needle 151 extending outwards from the pen body 2+3+6+10; the needle 151 being a long slender cylindrical shape; the needle 151 transferring a liquid medication into the body of a user; the proximal end of the medication cartridge 4 being attached to the pen body 2+3+6+10; the medication cartridge 4 being interchangeable within the pen body; the medication cartridge 4 being secured within the pen body 2+3+6+10; the dose adjustor 44 mechanically adjusting the quantity of medication being injected into the body of the user; the dose adjustor 44 being mechanically connected and controlled by the dose adjustment dial 6; the outer casing 2+3 being tubular in shape; the outer casing further comprising a dosage window 8; the dose adjustment dial 6 being tubular in shape; the dose adjustment dial 6 further comprising a plurality of numbers; and the injector button 10 being positioned on the top surface of the dose adjustment dial 6. Cronenberg does not disclose the outer casing comprising an LED light. Zhang Li discloses in Fig. 3, an outer casing 1 comprising a dosage window 1a showing a dosage numbers, similar to Cronenberg. Zhang Li teaches the outer casing 1 comprises an LED light 6 (read para. 0040). It would have been obvious to one of ordinary skill in the art at the time of filing to have modified Cronenberg to include the LED light taught by Zhang Li in order to illuminate to window for better visibility of the dosage (Zhang Li para. 0043). Regarding Claim 18, Cronenberg in view of Zhang Li teaches the claimed invention as discussed above. Cronenberg further discloses in Figs. 5-7, the dosage window 8 creating a cutout 7 on the outer surface (of the outer casing 2+3) at the proximal end of the outer casing 2+3; the dosage window revealing one of the plurality of numbers of the dose adjustment dial (read para. 0073). Zhang Li teaches the LED light of the combination including as shown in Fig. 3, the LED light 6 being secured along the proximal end of the dosage window 1a; and the LED light illuminating one of the plurality of numbers of the dose adjustment dial 3. Regarding Claim 20, Cronenberg in view of Zhang Li teaches the claimed invention as discussed above. Cronenberg further discloses in Figs. 5-7, the injector button 10 being mechanically connected to the pen body 2+3+6+10 (it is a portion of the pen body); the injector button 10 compressing when receiving an external surface force (read, e.g. para. 0073); and the injector button releasing the liquid medication from the medication cartridge when the injector button is compressed (read e.g. para. 0073). Claims 8, 15, and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Cronenberg (US 2019/0209782) in view of Zhang Li (CN209033383) as applied above, and further in view of Hirano (US 2003/0103418). Regarding Claims 8 and 15, Cronenberg in view of Zhang Li teaches the claimed invention as discussed above. Cronenberg in view of Zang Li does not disclose the plurality of numbers containing a phosphor substance; and the plurality of numbers glowing in low light conditions. Hirano discloses in Fig. 1, a dial 12 having a plurality of indicia 19 for a user to read and an associated LED light 20. Hirano teaches in Fig. 1 the LED light 20 emitting ultraviolet rays lighting the indicia (as read at para. 0068) the indicia 19 containing a phosphor substance (as read at para. 0067), the plurality of indicia glowing in low light conditions (emit light as read at para. 0068). It would have been obvious to one of ordinary skill in the art at the time of filing to have modified Cronenberg in view of Zhang Li further such that the LED light emits ultraviolet rays and the indicia, i.e. the dosage numbers of Cronenberg, contain a phosphor substance as taught by Hirano in order to improve visibility and emit colored light whenever a user desires (read e.g. Hirano para. 0073). Regarding Claim 19, Cronenberg in view of Zhang Li teaches the claimed invention as discussed above. Cronenberg further discloses in Figs. 5-7, the dose adjustment dial 6 rotating about the central axis of the dose adjustment dial (read para. 0073); the dose adjustment dial rotating to mechanically move the dose adjustor 44 (read para. 0109); the plurality of numbers being scribed along the outer surface of the dose adjustment dial 6 that traverse longitudinally (see threads 36 which move the dial 6 longitudinally when rotated and how the numbers which can be viewed through the window travel from the top to the bottom of surface 29; shown better in Fig. 17); and the dose adjustment dial slidably engaging with the inner surface of the outer casing (a function of the threads 36, the threads 36 of the dial 6 engaged with the internal threads 51 of the body as discussed at para. 0093). Cronenberg in view of Zang Li does not disclose the plurality of numbers containing a phosphor substance; and the plurality of numbers glowing in low light conditions. Hirano discloses in Fig. 1, a dial 12 having a plurality of indicia 19 for a user to read and an associated LED light 20. Hirano teaches in Fig. 1 the LED light 20 emitting ultraviolet rays lighting the indicia (as read at para. 0068) the indicia 19 containing a phosphor substance (as read at para. 0067), the plurality of indicia glowing in low light conditions (emit light as read at para. 0068). It would have been obvious to one of ordinary skill in the art at the time of filing to have modified Cronenberg in view of Zhang Li further such that the LED light emits ultraviolet rays and the indicia, i.e. the dosage numbers of Cronenberg, contain a phosphor substance as taught by Hirano in order to improve visibility and emit colored light whenever a user desires (read e.g. Hirano para. 0073).
