Office Action

§112
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 . 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 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. Claim Status In the amendment filed on February 2, 2026, claims 1-3, 6, 8, 10 and 11 have been amended. Therefore, claims 1-11 are currently pending for examination. Claim Objections Claims 1-3 are objected to because of the following informalities: Claim 1 recites “early warning unit vehicle-mounted hazardous chemicals” in multiple instances which appear to be a typographical error of “early warning unit of vehicle-mounted hazardous chemicals”. Claims 1 and 3 recite “configured to” followed by “ing” verbs. Claim 2 recites “ the chemicals physical and chemical safety monitoring” in line 2-3 which appears to be a typo. Appropriate correction is required. 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. Use of the word “means” (or “step for”) in a claim with functional language creates a rebuttable presumption that the claim element is to be treated in accordance with 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph). The presumption that 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph) is invoked is rebutted when the function is recited with sufficient structure, material, or acts within the claim itself to entirely perform the recited function. Absence of the word “means” (or “step for”) in a claim creates a rebuttable presumption that the claim element is not to be treated in accordance with 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph). The presumption that 35 U.S.C. 112(f) (pre-AIA 35 U.S.C. 112, sixth paragraph) is not invoked is rebutted when the claim element recites function but fails to recite sufficiently definite structure, material or acts to perform that function. Claim elements in this application that use the word “means” (or “step for”) are presumed to invoke 35 U.S.C. 112(f) except as otherwise indicated in an Office action. Similarly, claim elements that do not use the word “means” (or “step for”) are presumed not to invoke 35 U.S.C. 112(f) except as otherwise indicated in an Office action. 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: Claim 1 limitations “a physical and chemical safety monitoring and early warning unit”, “a vehicle-mounted gateway unit”, “an alarm prompt unit”, “a remote management unit”, “an anti-theft/robbery monitoring and early warning unit”, and “a hazardous chemical transportation emergency rescue guidance unit”. Claim 7 limitation “a vehicle local alarm prompt subunit” and “a remote monitoring client software alarm prompt subunit”. 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 wishes to provide further explanation or dispute the examiner’s interpretation of the corresponding structure, applicant must identify the corresponding structure with reference to the specification by page and line number, and to the drawing, if any, by reference characters in response to this Office action. If applicant does not intend to have the claim limitation(s) treated under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112 , sixth paragraph, applicant may amend the claim(s) so that it/they will clearly not invoke 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, or present a sufficient showing that the claim recites/recite sufficient structure, material, or acts for performing the claimed function to preclude application of 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. For more information, see MPEP § 2173 et seq. and Supplementary Examination Guidelines for Determining Compliance With 35 U.S.C. 112 and for Treatment of Related Issues in Patent Applications, 76 FR 7162, 7167 (Feb. 9, 2011). 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. Claims 1-11 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 pre-AIA the applicant regards as the invention. Claim 1 limitations “a physical and chemical safety monitoring and early warning unit”, “a vehicle-mounted gateway unit”, “an alarm prompt unit”, “a remote management unit”, “an anti-theft/robbery monitoring and early warning unit”, and “a hazardous chemical transportation emergency rescue guidance unit”, and Claim 7 limitation “a vehicle local alarm prompt subunit” and “a remote monitoring client software alarm prompt subunit” invoke 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. However, the written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. Therefore, the claim is indefinite and is rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. Applicant may: (a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph; (b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)). If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. Claims 2-11 are also rejected since they depend from the rejected claim 1. Allowable Subject Matter Claims 1-11 would be allowable if overcome 112 rejections and claim objections set forth above. The closest prior art Zhang et al. (CN110001499) teaches a system integrates functions such as detection, alarm, spraying, real-time uploading of onsite data, and emergency response after a leak occurs in a hazardous chemical transport vehicle (Par 35), but fails to teach at least “a vehicle-mounted hazardous chemicals anti-theft/robbery monitoring and early warning unit, wherein the vehicle-mounted hazardous chemicals anti-theft/robbery monitoring and early warning unit is associated with the vehicle-mounted gateway unit, and is associated with the alarm prompt unit and the remote management unit through the vehicle-mounted gateway unit; and the vehicle-mounted hazardous chemicals anti-theft/robbery monitoring and early warning unit is capable of performing real-time monitoring on anti-theft/robbery safety information of the vehicle-mounted hazardous chemicals, is capable of directly cooperating with the vehicle-mounted gateway unit according to monitored information to perform early warning analysis on a risk of being theft/robbed or lost on a vehicle carrying hazardous chemicals and the vehicle-mounted hazardous chemicals, and is capable of generating early warning information when the risk occurs, sending the early warning information to the remote management unit through the vehicle-mounted gateway unit, and simultaneously issuing a warning through the alarm prompt unit;” and “the hazardous chemical transportation emergency rescue guidance unit is capable of being linked with the vehicle-mounted hazardous chemicals physical and chemical safety monitoring and early warning unit and the vehicle-mounted hazardous chemicals anti-theft/robbery monitoring and early warning unit, and is capable of forming emergency disposal on-site guidance information for a vehicle driver when a vehicle triggers a vehicle-mounted hazardous chemicals physical and chemical safety monitoring and early warning and a vehicle-mounted hazardous chemicals anti-theft/robbery monitoring and early warning;”. Response to Arguments Applicant's arguments filed on 02/02/2026 have been fully considered but they are not persuasive. On page 14 of the Applicant’s Response, applicants argue that “Applicant submits that the claims recite units and modules of the safety management system for vehicle-mounted hazardous chemicals that comprise specific physical and structural elements. See FIGS. 1-18 and description thereof throughout the specification. As such, Applicant submits it is improper to apply the MPF clause in the construction of claims 1-11 under 35 U.S.C. 112 (f) or pre-AIA 35 U.S.C. 112, sixth paragraph.” In response, Examiner respectfully disagrees because Applicants arguments “FIGS 1-18 and description thereof throughout the specification” does NOT identify NOR clearly link the corresponding structure for performing the claimed function. The claim limitation(s) that are interpreted under 35 U.S.C. 112(f) clearly uses a generic placeholder (unit, subunit etc.) 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. However, the specification fails to disclose the corresponding structure to perform the entire claimed function and to clearly link the structure, material, or acts to the function. If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. Conclusion THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the date of this final action.
