Office Action

§112
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 . DETAILED ACTION Response to Amendment This Office action addresses claims 1-13 and 16-20. Claims 1-12 and 17-19 remain withdrawn from consideration. Claims 13, 16, and 20 are newly rejected under 35 USC 112(a) and (b) as necessitated by amendment. Accordingly, this action is made final. The double patenting rejection has also been withdrawn. Note: Although no prior art has been applied herein, the claims have not yet been indicated as containing allowable subject matter because of the 112 rejections noted below. Claim Rejections - 35 USC § 112 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. Claims 13, 16, and 20 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 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. Claim 13, as it is currently drafted, encompasses the recited method being either performed as pre-trip tests or as diagnostics during the transportation run (see also 112(b) rejection below as to ambiguity in the claim). It is submitted that there is insufficient support in the application as originally filed for the recited method to be performed as “diagnostics” within the transportation run. The claimed method steps correspond to Figure 3, which is shown and described in the specification as “pre-trip tests” (e.g., [0038] of publication). Figure 4, which does not correspond to the claimed method, is shown and described as “diagnostics.” There is insufficient support for the method steps of claim 13 being performed as diagnostics within a transportation run as now encompassed by the claim. 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 13, 16 and 20 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. It is unclear if claim 13 as amended recites that both the pre-trip tests and the diagnostics during a transportation run are capable of performing the claimed method steps (validating, operating, determining, issuing) when activated by the test button. Based on the specification, it appears that only the pre-trip test performs the claimed method (see rejection above), leading to ambiguity in the claim. Correction is required. Conclusion A complete reply to this Office action should also include cancellation of nonelected claims 1-12. 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 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.
