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 Amendment The proposed amendments filed 09/30/2025 has been entered. Claims 1-11 and 13-23 are currently pending. 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 1-11 and 13-23 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. Independent claim 1 has been amended to recite “a second cable tray, the second cable tray extending between the VFD and the first fracturing pump, the second cable tray including cables extending between the VFD and the first fracturing pump, the cable tray providing for operative communication between the VFD and the first fracturing pump during transportation of the integrated fracturing system” and independent claim 10 has been amended to recite “a second cable tray, the second cable tray extending between the VFD and the first fracturing pump, the second cable tray including cables extending between the VFD and the first fracturing pump, the cable tray providing for operative communication between the VFD”. The inclusion of the second cable tray and the specific structures for the wiring is not sufficiently supported int the specification nor in the figures. The new claim language is therefore not supported and is considered new matter. Dependent claims 2-9, 11, and 13-23 are rejected for being dependent from unsupported claims. 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 and 13-23 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 1 recites “the cable tray providing for operative communication between the VFD and the first fracturing pump during transportation of the integrated fracturing system” where the Examiner is unclear as to which cable tray is being referred back to by the Applicant. The structure of the claim appears to show the unspecified cable tray is meant to call back to the second cable tray and will be interpreted as such. Claim 10 recites “the cable tray providing for operative communication between the VFD and the first fracturing pump during transportation of the integrated fracturing system” where the Examiner is unclear as to which cable tray is being referred back to by the Applicant. The structure of the claim appears to show the unspecified cable tray is meant to call back to the second cable tray and will be interpreted as such Claim 23 recites “wherein the cable tray extends along the gooseneck portion of the trailer” where the Examiner is unclear as to which cable tray is being referred to. A review of the provided specification and drawings shows that the gooseneck is closest to the VFD and therefore the second cable tray is being interpreted as extending along the gooseneck portion. Claims 2-9, 11, and 13-22 are rejected for being dependent from an unclear and indefinite claim. 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.
