Office Action

§103
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 . Applicant's submission filed on 08/13/2026 has been entered. Claims 1-20 are still pending. 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. Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over KATO in a view of Flores et a. US 2021/0403277 A1. Regarding claim 1, KATO discloses A method of providing assisted conveyance system maintenance, the method comprising: receiving, at a predictive system, a request for analysis of a change of an operating parameter (Change or addition) of a conveyance system (elevator) (abstract section); PNG media_image1.png 227 913 media_image1.png Greyscale ; and sending, from the predictive system to a user device (Display), a response including the effect of changing the operating parameter of the conveyance system. PNG media_image2.png 391 917 media_image2.png Greyscale PNG media_image3.png 514 886 media_image3.png Greyscale KATO does not teach but Flores at el. teach at the predictive system, predicting an effect of changing the operating parameter (retuning) of the conveyance system and determining if changing the operating parameter (whether needs retuning) of the conveyance system is recommended or not [0025], wherein the response includes a visual indication (via GUI) of whether changing the operating parameter of the conveyance system is recommended [0020, 0025, 0029], the method further comprising accepting the changing of the operating parameter of the conveyance system and initiating a test run of the conveyance system using the updated operating parameter [0030, 0058, 0064]. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to determine if changing the operating parameter is recommended or not along with a visual indication and initiating a test run as disclosed by Flores in KATO’s teachings to enhance performance, passenger comfort and efficiency. Regarding claim 8, KATO discloses A system (fig. 1, item 100) for providing assisted conveyance system (elevator system) maintenance, the system comprising: a predictive system in communication with a user device (item 108) over a network (via items 101 and 102), the predictive system configured to perform operations including: receiving, at the predictive system, a request for analysis of a change of an operating parameter of a conveyance system; PNG media_image4.png 310 876 media_image4.png Greyscale ; and sending, from the predictive system to the user device, a response including the effect of changing the operating parameter of the conveyance system. PNG media_image5.png 242 975 media_image5.png Greyscale PNG media_image6.png 416 975 media_image6.png Greyscale PNG media_image7.png 566 975 media_image7.png Greyscale KATO does not teach but Flores at el. teach at the predictive system, predicting an effect of changing the operating parameter (retuning) of the conveyance system and determining if changing the operating parameter (whether needs retuning) of the conveyance system is recommended or not [0025], wherein the response includes a visual indication (via GUI) of whether changing the operating parameter of the conveyance system is recommended [0020, 0025, 0029], the operation further comprising accepting the changing of the operating parameter of the conveyance system and initiating a test run of the conveyance system using the updated operating parameter [0030, 0058, 0064]. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to determine if changing the operating parameter is recommended or not along with a visual indication and initiating a test run as disclosed by Flores in KATO’s teachings to enhance performance, passenger comfort and efficiency. Regarding claim 15, a combination of KATO and Flores et al. discloses A computer program product embodied on a non-transitory computer-readable storage medium (item 101), the computer program product including instructions for causing a processor (inherent part of the elevator system 100) to implement a process providing assisted conveyance system maintenance, the process comprising: receiving, at a predictive system, a request for analysis of a change of an operating parameter of a conveyance system; at the predictive system, predicting an effect of changing the operating parameter of the conveyance system; and determining if changing the operating parameter of the conveyance system is recommended or not; and sending, from the predictive system to a user device, a response including the effect of changing the operating parameter of the conveyance system ,wherein the response includes a visual indication of whether changing the operating parameter of the conveyance system is recommended; the process further comprising accepting the changing of the operating parameter of the conveyance system and initiating a test run of the conveyance system using the updated operating parameter (see claim 8 rejection for detail). Regarding claims 2, 9 and 16, KATO discloses training the predictive system (via simulation) using one or more of engineering specifications, service records, customer complaints and history of operating parameters changes (Change of usage time). PNG media_image8.png 183 861 media_image8.png Greyscale PNG media_image9.png 111 865 media_image9.png Greyscale Regarding claims 3, 10 and 17, KATO discloses , wherein the response includes an impact analysis (improvement) of changing the operating parameter of the conveyance system. PNG media_image10.png 242 975 media_image10.png Greyscale Regarding claims 4 ,11 and 18, KATO discloses , wherein the response includes a dependency analysis (via improvement measure data 111) of changing the operating parameter of the conveyance system. PNG media_image11.png 225 890 media_image11.png Greyscale Regarding claims 5, 12 and 19, KATO discloses , wherein the response includes how changing the operating parameter of the conveyance system affects other operating parameters of the conveyance system. PNG media_image6.png 416 975 media_image6.png Greyscale Regarding claims 6, 13 and 20, KATO discloses the predictive system performing adaptive learning (simultaneously comparing) based on data points obtained from the conveyance system over time. PNG media_image12.png 146 940 media_image12.png Greyscale Regarding claims 7 and 14, KATO discloses , wherein the conveyance system is one of an elevator, escalator and moving walkway (abstract section). Response to Arguments Applicant’s arguments with respect to claims have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. The examiner also withdraws 35 USC § 101 rejection based on applicant’s amendment and arguments. Conclusion THIS ACTION IS MADE FINAL. 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.
