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 . Summary Claims 1-16, 21, and 22 are pending. Claims 1-16 are allowed. Claims 21 and 22 are rejected. This is a Final Rejection as necessitated by the amendment and arguments (hereinafter “the Response”) dated 26 Feb 2026. Claim Rejections - 35 USC § 112(a) 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(s) 22 is/are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. Regarding claim 22: Claim 22 recites “a body extending from the top of the flange, and including an outer surface formed as a continuous closed surface.” This limitation is not enabled by the Applicant’s disclosure. In every embodiment set forth in the specification, the body has a hole in the top for the probe to protrude through. See probe 16 in FIG. 2 with the hole clearly seen in FIG. 3A between 52A and 56. Therefore it is not enabled for the outer surface of the body to have a continuous closed surface. Claim Rejections - 35 USC § 112(b) 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(s) 21 and 22 is/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 claims 21 and 22: Claims 21 and 22 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being incomplete for omitting essential elements, such omission amounting to a gap between the elements. See MPEP § 2172.01. The omitted elements are: “a probe extending from the strut” as recited in claim 1. Both of these claims recite “an aircraft sensor” in the preamble, however there is no sensing element recited. Therefore, there is no structure recited in the claim that would make recited invention a sensor. Allowable Subject Matter Claims 1-16 are allowed. The following is an examiner’s statement of reasons for allowance: Independent claim 1 contains allowable subject matter. None of the prior art of record teaches or suggests the claimed invention. Specifically not found in the prior art of record are the limitations of a flange connected to and extending radially outward from a top portion of the housing and a vent shaft fluidly connected to a bore and including an outlet wherein the outlet is located on an opposite side of the flange from the closed end of the bore, in combination with the other limitations of claim 1. The closest prior art of record has been discussed in the previous office action. Claims 2-16 are allowed due to their dependence on 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.” Response to Amendment/Argument The amendments to the claims to overcome the previous objections are acknowledged and said objections are accordingly withdrawn. The amendments to the claims to overcome the previous rejections under 35 U.S.C. 112 are acknowledged and the previous rejections are accordingly withdrawn. Please note that there are still outstanding 112 rejections based on the language of new claims 21 and 22. 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.
