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 . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the Claim 57 “a supporting ring” must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections Claim 53 is objected to because of the limitation “the first lock body” in paragraphs 3 and 4. It is suggested amending the limitation to “the first displaceable lock body.” Appropriate correction is required. Claims 54-60 need similar amendments. Appropriate correction is required. 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 53-72 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. Claim 59 recites “the lock body” in line 2. It is not clear whether the “lock body” refers which lock body, the first lock body or the second lock body. Appropriate correction is required. Claim 53 recites the limitation "“the first lock body” in paragraphs 3 and 4. There is insufficient antecedent basis for this limitation in the claim. Appropriate correction is required. Claims 54-60 recite the limitation "“the first lock body.” There is insufficient antecedent basis for this limitation in the claim. Appropriate correction is required. Claim 60 recites “the latch” in line 5. There is insufficient antecedent basis for this limitation in the claim. Appropriate correction is required. Claim(s) that depend(s) from the rejected claim(s), that is, claim(s) 61-72 is/are rejected.

Abstract. Para. [0003].) 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 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) 55 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cetnar (US Pub. App. 2007-0210588) in view of Ginsburg (US Patent No. 3,527,268). For claim 55, Cetnar discloses the latch mechanism according to claim 54, But does not disclose wherein: the gear arrangement has a gear ratio selected to ensure a sufficient amount of torque is exerted on the first lock body to pivotably displace same between active and inactive configurations (18 and 20 are rotated during locking and unlocking, para. [0025-0027]. Hence, there must be sufficient torque to operate the locking system.) Cetnar does not disclose the gear ratio is between 1:40 and 1:100; and the gear arrangement comprises one of a bevel gear arrangement, spur gear arrangement, worm gear arrangement, spur and crown arrangement, rack and pinion arrangements and a multistage gear arrangement. Ginsburg teaches a lock assembly with a worm gear (Col.16, L59), bevel gear (Col.18, L32), and the gear ratio can be adjusted depending upon the need (Col.18, L32-35). Ginsburg teaches a method of gear arrangement to select the gear ratio to depending upon the need. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Cetnar with a gear arrangement to have desired gear ratio (including between 1:40 and 1:100), as taught by Ginsburg with a reasonable expectation of success of providing a gear arrangement with gear ratio between 1:40 and 1:100 depending on the need of the environment. Claim(s) 72 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cetnar (US Pub. App. 2007-0210588) in view of Tran (US Pub. App. 2007-0290793). For claim 72, Cetnar discloses the structure according to claim 71, further comprising a control unit for controlling automated actuating mechanisms of the one or more latch mechanism; at least a first sensor device provided in communication with the control unit, wherein the control unit is associated with a siren or alarm module and wherein the first sensor device is selected from a list comprising: a motion detector device; a smoke detector device; a temperature sensing device; a sound detector device; a door or window proximity sensor; and a light sensor (Controller 210. Abstract. Figure 8.) Tran teaches mesh network door lock with at least a sensor provided in communication with the control unit, wherein the control unit is associated with a siren or alarm module and wherein the first sensor device is selected from a list comprising a motion detector device.; a smoke detector device; a temperature sensing device; a sound detector device; a door or window proximity sensor; and a light sensor (the network nodes can be mesh network appliances to provide voice communications, home security, door access control, lighting control, power outlet control, dimmer control, switch control, temperature control, humidity control, carbon monoxide control, and fire alarm control. Para. [0026].) Tran teaches a method of automatic control of the lock operation efficiently and remotely. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Cetnar to have at least a first sensor device provided in communication with the control unit, wherein the control unit is associated with a siren or alarm module and wherein the first sensor device is selected from a list comprising: a motion detector device; a smoke detector device; a temperature sensing device; a sound detector device; a door or window proximity sensor; and a light sensor, as taught by Tran with a reasonable expectation of success of having an automatic control of the lock operation efficiently and remotely. Conclusion Prior art made of record and not relied upon is considered pertinent to applicant's disclosure and provides examples of similar inventions. There are no suggestions in the prior art of record for combining any of the references to arrive at as claimed. A few of the prior art cited but not applied includes Mills (US 5,632,702); House (US 8,499,495); and Kleefeldt (US 4,440,006).
