Office Action

§103
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Arguments Applicant’s arguments in combination with amendments, see Remarks and Claims, filed 12/18/2025, with respect to the rejection(s) of claim(s) under 35 USC 103 have been fully considered. The applicant argues that Hay’s listening component receives a voice command, which is then communicated to a different piece of medical equipment (see remarks page 15), and argues that Hay’s fails to teach a “first medical device having both an audio acquisition apparatus and a processor, wherein the audio acquisition apparatus acquires a voice signal that carries a medical procedure instruction and the processor” (see page 16). These arguments are fully considered but are not persuasive. Initially, it is noted that the claim does not provide any details of the structure of the medical device, the location of the processor, audio acquisitor apparatus, etc. Therefore, any device which includes the components, whether integrated or not, would read over the claimed limitation. Furthermore, Hays discloses a microphone configured to receive voice commands from a user; a medical device associated with a patient; a processor in communication with the microphone and the medical device associated with the patient [] the processor to receive a voice command that has instructions for the medical device associated with the patient, translate the instructions for use by the medical device, and send the translated instructions to the medical device (e.g., para 0010). The device may also comprise a processor [] The device may further comprise computer-readable media storing instructions that may be executed by the processor to receive, at the microphone, a voice command, translate the voice command into instructions for the medical equipment, and communicate the instructions to the medical equipment so that the medical equipment may take an action on a patient in accordance with the instructions (para, 0021). It is also noted that making components integral would be merely a matter of obvious engineering choice and not novel on its own. In re Larson, 340 F.2d 965, 968, 144 USPQ 347, 349 (CCPA 1965). However, in order to advance prosecution, the limitation of “ processor of the first medical device” will be read as argued by the applicant. Therefore, Hays would have disclosed having a processor associated with the first medical device but fails to explicitly disclose “the processor of the first medical device”. For the reasons recited above, the applicant’s arguments are fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made further in view of US Pat Pub No. 20180227719 to Chong et al. (hereinafter “Chong”). See details below. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) is/are rejected under 35 U.S.C. 103 as being unpatentable over US Pat Pub No. 20190038236 granted to Hays et al. (hereinafter “Hays” – previously presented ) in view of US Pat Pub No. 20180227719 to Chong et al. (hereinafter “Chong”). Regarding claim 1. (Original) Hays discloses a first medical device (e.g., para 0021 “device”), comprising: an audio acquisition apparatus, configured to acquire a voice signal (para 0021, “listening component, such as a microphone, that is configured to receive a voice command from a user”, para 0032 “listening device 200”) and to send the voice signal to a processor of the first medical device (para 0021 “processor”), wherein the voice signal carries a medical procedure instruction and is inputted by a user (para 0021 “processor to receive, at the microphone, a voice command, translate the voice command into instructions for the medical equipment, and communicate the instructions to the medical equipment”), the medical procedure instruction is operable to instruct at least the first medical device to execute a preset medical procedure (para 0021 “processor to receive, at the microphone, a voice command, translate the voice command into instructions for the medical equipment, and communicate the instructions to the medical equipment”), wherein the medical procedure comprises a plurality of preset medical actions, and there is a preset corresponding relationship between the medical procedure instruction and the plurality of preset medical actions (para 0021 “medical equipment may take an action on a patient in accordance with the instructions”, para 0023 “medical device 230”, para 0043); and the processor, configured to determine the plurality of preset medical actions that corresponds to the medical procedure instruction (para 0021), and to control execution of the plurality of medical actions after receiving the voice signal (para 0021), wherein: when the plurality of medical actions include a first medical action for execution by the first medical device and a second medical action for execution by a second medical device, different from the first medical device (para 0041 “ECG monitor”, “infusion pump 232”, etc.), the processor is further configured to: determine an execution sequence for the plurality of medical actions; and control execution of the first medical action by the first medical device and the second medical action by the second medical device according to the execution sequence (para 0021, 0041-0042, etc.). Hays teaches having a processor associated with the first medical device but fails to explicitly disclose the processor of the first medical device. Chong, from a similar field of endeavor teaches having a first medical device (i.e., medical voice command device) and teaches that it is known for the processing of the voice command and the determination of a medical device to use for satisfying the voice command may be determined by a medical voice command device that received the voice command (para 0073). It would have been obvious to one of ordinary skill in the art to modify the disclosure of Hays with the known teachings of Chong to provide the predictable result of processing the voice commands and the determination of a medical device to use for satisfying the voice command by the medical voice command device that received the voice command, removing the need for a network. The applicant should note that Chong also teaches various other limitations of the independent claim and should be considered in its entirety. Specific paragraphs of interest are [0017], [0021], [0023-0024], [0073], etc. Regarding claim 2.
