DETAILED ACTION 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 . Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “a monitoring system for monitoring an environmental status” in claim 1. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 1, 3, and 17 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 1, claim 1 recites the limitation “a monitoring system for monitoring an environmental status " in line 3. It is unclear what the corresponding structure is/are. Examples of the monitoring devices and associated sensors are described in further detail herein with reference to FIGS. 7 and 8 (par. 0039). Also, the example receptacle 194 is provided for connecting the automatic control unit 102 with one or more environmental sensors (e.g., of the zone monitoring systems 106, shown in FIG. 1), for monitoring the respective zones. Additionally, the pressure gauge 224 is an example of a sensor of the zone monitoring system 106 (FIG. 1), which detects operational status information and provides it to the sensor inputs 144 (FIG. 5). In some embodiments the automatic control unit 102 receives status information from the respective zone monitoring systems 106 (par. 0017). In some configurations, the automatic control unit 102 monitors the status information, and when the status information indicates that a fire has started (par. 0018). It is unclear if the monitoring system is the sensors, or separate and/or it is a component of the automatic control unit. Regarding claim 3, claim 3 recites the limitation “a plurality of fire protection units.” It is unclear if this limitation is referring to multiple of the “fire protection units” in claim 1 or additional different ones from the unit in claim 1. Regarding claim 17, claim 17 recites the limitation “mount component" in line 1. There is insufficient antecedent basis for this limitation in the claim. Claim 1 doesn’t recite the limitation “mount component”. It will be presumed that claim 17 depends upon claim 16 until further clarification. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

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. Claim(s) 4 is rejected under 35 U.S.C. 103 as being unpatentable over Baron (WO 2020/161643) in view of Shavit (WO 2021/165972). Regarding claim 4, Baron fails to disclose wherein the automatic control unit individually monitors each of the zones for a fire, and individually activates a particular one of the fire protection units when the fire is detected in the zone associated with the particular one of the fire protection units. However, Park discloses wherein the automatic control unit (sensors, par. 0083) individually monitors each of the zones for a fire (If there is a fire detected by sensors of an individual endpoint, par. 0083), and individually activates a particular one of the fire protection units when the fire is detected in the zone associated with the particular one of the fire protection units (then the COFD application may start an “isolated” mode of operation, activating the water gun of just the given endpoint, par. 0083). Therefore, it would have been obvious for one skilled in the art at the time of the invention to have the motivation to modify the automatic control unit of Baron to individually monitors each of the zones for a fire, and individually activates a particular one of the fire protection units when the fire is detected in the zone associated with the particular one of the fire protection units as taught by Shavit for the benefit of controlling fires in individual zones. Claim(s) 5-9 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Baron (WO 2020/161643) in view of Council et al. (US 2020/0338375). Regarding claim 5, Baron fails to disclose an output device, wherein the output device generates an alert when the fire has been detected. However, Council et al. discloses an output device (output system, par. 0042), wherein the output device generates an alert when the fire has been detected (alarm module for sounding an alarm if an alert is detected, claim 6 and a remote alert system and/or responds to a local sensor that senses fire, par. 0015). Therefore, it would have been obvious for one skilled in the art at the time of the invention to have the motivation to add an output device, wherein the output device generates an alert when the fire has been detected as taught by Council et al. in the automatic control unit of Baron for the benefit of notifying and alerting necessary personnel to the presence of a fire.

Regarding claim 8, Baron fails to disclose wherein the output device is an auxiliary output device that is separate from the automatic control unit but controllable by the automatic control unit to generate the alert. However, Council et al. discloses wherein the output device is an auxiliary output device (controller 300, par. 0040) that is separate (controller 300 may include output system 302, par. 0040. Therefore, is separate.) from the automatic control unit but controllable by the automatic control unit to generate the alert. (a controller responds to an alert, and, in response, sends signals, par. 0004). Therefore, it would have been obvious for one skilled in the art at the time of the invention to have the motivation to add wherein the output device is an auxiliary output device that is separate from the automatic control unit but controllable by the automatic control unit to generate the alert as taught by Council et al. in the automatic control unit of Baron for the benefit of allowing external control of said fire extinguishing system. Regarding claim 9, Baron fails to disclose wherein the auxiliary output device is a wireless communication device that wirelessly transmits the alert to a remote computing device. However, Council et al. discloses wherein the auxiliary output device is a wireless communication device that wirelessly transmits the alert to a remote computing device (controller 300 (which may include…wireless component 114 communication), which may control the delivery devices 208 and/or communications with the user, par. 0024). Therefore, it would have been obvious for one skilled in the art at the time of the invention to have the motivation to add wherein the output device is an auxiliary output device that is separate from the automatic control unit but controllable by the automatic control unit to generate the alert as taught by Council et al. in the automatic control unit of Baron for the benefit of allowing external control of said fire extinguishing system. Regarding claim 12, Baron fails to discloses wherein the automatic control unit is further configured to output at least one anomaly alert, wherein the anomaly alert is based on at least one of an operational status or an environmental status. However, Council et al. discloses wherein the automatic control unit is further configured to output at least one anomaly alert (for sounding an alarm, claim 6), wherein the anomaly alert is based on at least one of an operational status or an environmental status (an alarm module for sounding an alarm if an alert is detected, claim 6). Therefore, it would have been obvious for one skilled in the art at the time of the invention to have the motivation to output at least one anomaly alert, wherein the anomaly alert is based on at least one of an operational status or an environmental status in the automatic control unit of Baron for the benefit of sensing and communicating the detection of fires. Claim(s) 10 is rejected under 35 U.S.C. 103 as being unpatentable over Baron (WO 2020/161643) in view of Enk (US 8,973,670). Regarding claim 10, Baron fails to discloses wherein the monitoring system further monitors an operational status of the fire protection unit. However, Enk discloses wherein the monitoring system (control panel 58, col. 9, line 22) further monitors an operational status of the fire protection unit (The tracking device may also be in electronic communication with control panel 58 and when scanned can convey the real-time operational status of one or more components of the fire suppressions system, col. 9, line 21-25). Therefore, it would have been obvious for one skilled in the art at the time of the invention to have the motivation to modify the monitoring system of Baron with further monitoring an operational status of the fire protection unit as taught by Enk for the benefit of real-time status updates about the fire suppression system. Claim(s) 11 is rejected under 35 U.S.C. 103 as being unpatentable over Baron (WO 2020/161643) in view of Dunster et al. (US 2013/0098637).
