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 Acknowledgment is made of the amendment filed 1/14/2026, in which:claims 1, 6, and 19-20 are amended; and the rejections of the claims are traversed. Claims 1-20 are currently pending and an Office Action on the merits follows. CLAIM REJECTIONS - 35 USC § 103 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. 1. Claims 1-5 and 7-20 are rejected under 35 U.S.C. 103 as being unpatentable over Lagowski et al. US 20200019034 in view of Budhia et al. US 10744936 in view of Zedlitz et al. US 20200057346 and further in view of Roy US 11351892. Consider claim 1. Lagowski discloses a control system for a vehicle fig. 7 control system of vehicle 12 including 98, the control system comprising: a processor fig 7 Processor 94; and memory coupled to the processor fig 7 processor 94 is in communication with memory 96 [0057] and storing instructions that, when executed by the processor [0057] configured to store various instructions and routines configured to control the window control module 50 or modules in communication with the controller 90 , cause the control system to: retrieve a plurality of context data inputs associated with the vehicle see fig. 7 sensor data is sent to controller 90 (e.g. 22, 27, 26, 24, 34 ) and fig. 6 74-78 and 80, wherein the context data inputs include location information for the vehicle [0026] navigation system and directional sensor 34 which includes GPS and directional sensors (e.g., compass, magnetometer, etc.) and one or more of: type information for the vehicle, a driving mode of the vehicle [0026]change in a heading direction identified by the directional sensor of the navigation system 34 , an ambient condition for the vehicle [0026] the time of day, and the geographic region in which the vehicle 10 is operating [0024] exterior light sensor may comprise an ambient light sensor, and a user preference associated with the vehicle [0037][0042] use preset settings or manual adjustment of dimming windows. Allowable adjustment may range from a fully clear or nearly fully clear state to a fully darkened state. [0056] fig. 7 manual control via user interface 92; determine, based on the context data inputs, a tint value fig. 4 [0048] window control module 50 may be operable to control a voltage or other electrical attribute supplied to each of the dimming zones for a portion of dimmable glass coupled to the vehicle fig. 6 74-80[Wingdings font/0xE0]82 [0052-0054] based on sensor data 22 24 26 27 28 and also vehicle operation direction and geographic data each of the dimming windows and or dimming zones is controlled , wherein determining the tint value includes determining a respective weighted visible light transmission value for each respective context data input in the plurality of context data inputs fig. 6 74-80[Wingdings font/0xE0] 82 [0052-0054] note that each sensor’s reading is factored in which controlling each dimming window and dimming zones; generate a command to control the portion of dimmable glass that includes the determined tint value fig. 6 74-80[Wingdings font/0xE0]82 [0054] controller 90 of the window control system 12 may control each of the dimming windows 14 and dimming zones 16; and; and transmit the command to a dimming controller coupled to the portion of dimmable glass to control a tinting level of the portion of dimmable glass according to the determined tint value. fig. 7 controller sends signal to window control module fig. 6 74-80[Wingdings font/0xE0]82 [0054] controller 90 of the window control system 12 may control each of the dimming windows 14 and dimming zones 16; and Lagowski does type information for the vehicle and respective weighted visible light transmission value.

RESPONSE TO ARGUMENTS Applicant's arguments have been fully considered but are moot in view of the new grounds of rejection. Applicant argues (pages 7-8) that the cited references do not disclose the features of the amended claim. The Office agrees and has accordingly updated the rejection to address the newly added limitations to claims 1, 6, and 19-20 (see rejection above for details). 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 extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action.
