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 . Response to Arguments The examiner agrees the amendments overcome the prior art however new claim 11 raises new matter issues. Drawings The previous drawing objections are overcome by the present amendments. Claim Rejections - 35 USC § 112(a) The previous 112(a) rejections are overcome by the present amendments however new issues have arisen. The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claim 11 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. In regards to claim 11, the combination of both the “buffer” and the “transmission base” is new matter. Both of these features exist separately in different embodiments but not together. Furthermore, the specification does not reasonably convey that the inventors had possession of both in the same embodiment. Claim Rejections - 35 USC § 112(b) The previous 112(b) rejections are overcome by the present amendments Allowable Subject Matter Claims 4-5 and 8-10 allowed. The following is a statement of reasons for the indication of allowable subject matter: The prior art does not teach or fairly suggest electronic door lock as claimed in independent claim 1 of the instant application. The examiner can find no motivation to combine or modify the references of record without the use of impermissible hindsight. Regarding claim 1, the prior art of record, including Liang (TW M404254 U) and Menta (US 20060021404 A1), teaches electronic door locks having much of the claimed structure, but fails to teach each and every limitation of the claims. Specifically, the prior art fails to teach the elastic body is a torsion spring, and the buffer is a torsion spring, in addition to the other claimed structure and functionality. One of ordinary skill in the art would not find it obvious to modify the structure and functionality of the elastic body of the prior art to be configured and to function as claimed in the instant application without the use of hindsight and/or destroying the references. Therefore, the prior art does not disclose the electronic door lock of claim 1. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, 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 nonprovisional extension fee (37 CFR 1.17(a)) 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 mailing date of this final action.
