The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 2 & 11 are rejected under 35 U.S.C. 103 as being unpatentable over Cerman (US 2017/0266370) in view of Hogset et al. (US 2016/0199664). Regarding claims 2 & 11, Cerman discloses all the claimed subject matter as required. Cerman discloses that the strap 150 is elastic. Therefore, the strap 150 by itself includes an adjustable fastener to secure the brace to a body part. In case, Applicant disagrees with Examiner’s statement above. Assuming the brace in Cerman does not include an adjustable fastener. The device in Cerman can be modified as below. Hogset discloses an injection system 2 comprising: a brace 3a & 3b; an adjustable fastener (elements 4 & 5) to secure the brace to a body part. It would have been obvious to one of ordinary skill in the art, prior to the effective filling date of the claimed invention to modify the brace device of Cerman with including an adjustable fastener, as taught by Hogset, in order to secure the brace and the injection device to different locations of a body part in different sizes of patients. Claims 3-4, 12-13 are rejected under 35 U.S.C. 103 as being unpatentable over Cerman (US 2017/0266370) in view of Peeters et al. (US 8,909,391). Regarding claims 3-4 & 12-13, Cerman discloses all the claimed subject matter as required. The injection device in Cerman includes a controller 101 that is configured to control operation of various components or controlling needle insertion through a skin and delivering drug into a patient. Therefore, the injection device includes a memory storing an application (software of controlling the insertion of the needle or drug delivery to a patient); a beacon provided on/in the brace. Cerman does not disclose the limitations that: an unmanned vehicle to carry and deploy the brace; a speaker; a microphone; and a processor which executes the application to: cause the speaker and microphone to operate as a communication device. Peeters discloses a deployment system for an unmanned aerial vehicle (UAV) comprising: an unmanned vehicle (UAV) to carry and deploy a package (brace) for particular medical situation; a speaker; a microphone; a beacon (flashing a light); a memory storing an application (module) that is able to signal to a passerby for assistance in either reaching the specific location or delivering its medical support items to the medical situation, col. 14, lines 34-49; processor which executes the application/module to cause the speaker and microphone to operate as a communication device. It would have been obvious to one of ordinary skill in the art, prior to the effective filling date of the claimed invention to modify the injection system of Cerman with providing/including an unmanned vehicle to carry and deploy the brace; a speaker; a microphone; and a processor which executes the application to: cause the speaker and microphone to operate as a communication device; a beacon, as taught by Peeters, in order to deploy the medical package to provide medical support for patient who is currently in medical attention as needed. Claims 6 & 14 are rejected under 35 U.S.C. 103 as being unpatentable over Cerman (US 2017/0266370). Regarding claims 6 & 14, Cerman discloses that wherein the needle is an intraosseous needle. Thus, a person skilled in the art would recognize that the needle 110 can be an intraosseous needle, as for intended use purpose in certain medical condition. Claims 9 & 17 alternatively are rejected under 35 U.S.C. 103 as being unpatentable over Cerman (US 2017/0266370) in view of Gunay et al. (US 2023/0256159). Note: incase Applicant still disagrees with Examiner about the rejection in claim 9 above, the claim 9 is alternatively being rejected as below. Regarding claim 9, wherein the brace further comprises: one or more sensors to detect a position of the brace with respect to a body part (e.g., the sensor arrangement 153 is operable to detect a force that is provided on the strap 150 by the limb of the patient, para [0059]. It is noted that the sensor is configured to detect a force that provided on the strap is interpreted that the sensor is configured to detect a position of the brace on the body part); Assuming that Cerman fails to disclose the limitation that: the processor further executing the application to determine whether to cause the mechanism to extract the needle based on the position of the brace with respect to the body part. Gunay discloses an injection system comprising: a needle 51; a memory 264 storing an application; a processor 262, see Fig. 10; wherein one or more sensors, i.e. skin sensor to detect a position of the brace/housing with respect to a body part (e.g., the skin sensor which senses whether the device is properly positioned against a patient’s skin); and the processor which executes the application (software) to cause the mechanism to extract/extend the needle comprises: the processor further executing the application to determine whether to cause the mechanism to extract the needle based on the position of the brace with respect to the body part (e.g., para [0089], cassette 100 comprises a skin sensor which senses whether the device is properly positioned against a patient's skin. In some embodiments, the cassette 100 may not actuate a needle assembly or deliver a medication if the skin sensor does not indicate that the device is positioned properly. In other words, if the position of the brace/housing of the device is positioned incorrectly to the patient’s skin, the processor does not execute a needle assembly to deliver a medication. If the position of the brace/housing of the device is positioned correctly to the patient’s skin, then the processor further executing the application to cause the mechanism to extend/extract the needle to delivery drug into a patient’s skin). It would have been obvious to one of ordinary skill in the art, prior to the effective filling date of the claimed invention to modify the brace/housing device of Cerman with including a skin sensor to sense the injection needle being in positioned correctly with respect to the skin’s patient, as taught by Gunnay, in order to secure the brace of the injection device in correct position to deliver a drug into the patient.
