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 . 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. Claims 1-19 are rejected under 35 U.S.C. 103 as being unpatentable over Simonian et al. (US 2013/0307419) in view of Baaijens et al. (US 2015/0061506). In regards to claim 1, Simonian discloses of a color temperature controller, comprising: control circuitry (for example 120) to: receive data from one or more sensors (for example 170, 170A, 170B) disposed in a space (for example 300, 340, see Figs 1, 3, 5 and Paragraphs 0001, 0037, 0041); determine an activity occurring in the space (300, 340) based on the received data from the one or more sensors (170, 170A, 170B) disposed in the space (300, 340, for example see Paragraphs 0001, 0038, uses measurements from the sensors to adjust the light based on a desired lighting objective, an example including an activity in the environment/are being utilized as a workspace); identify a target color temperature and a target intensity based on the determined activity in the space (for example see Paragraphs 0019, 0022, 0024-0025, 0027-0030, 0033-0034, 0036-0043, 0045-0046, represent the desired lighting and intensity and adjust according to the sensors based on the desired lighting objective); determine an output intensity for each respective one of a plurality of light sources (for example 110-1:110-N) such that, when combined, the color temperature and intensity contributed by each of the plurality of light sources (110-1:110-N) produces a combined luminous output at the received target color temperature and the received target intensity; wherein at least two of the plurality of light sources (110-1:110-N) include light sources having different output spectra (for example see Paragraph 0021, 0025); and cause each of the plurality of operatively coupled light sources (110-1:110-N) to produce the respective determined output intensity (for example see Paragraphs 0022, 0024-0025, 0030, 0034, 0038-0039, 0045-0046). However, Simonian does not explicitly disclose of the received data is indicative of at least one of a movement or a location of one or more occupants within a space; determine occupant activity using the data; and identify target color temperature and intensity based on the determined occupant activity.

In regards to claim 19, Simonian in view of Baaijens disclose of the non-transitory, machine-readable, storage device of claim 15 wherein the instructions that cause the color temperature control circuitry (120) to determine the output intensity for each respective one of the plurality of light sources (110-1:110-N) further causes the color temperature control circuitry (120) to: determine the output intensity for each respective one of a plurality of light-emitting diode (LED) light sources (for example see Simonian Paragraphs 0020-0024). Response to Arguments Applicant's arguments filed 2/20/2026 have been fully considered but they are not persuasive. The Applicant argues that the prior art fails to disclose of determining an occupant activity in the space using data received from one or more sensors in the space; however, the Examiner respectfully disagrees. As found within the explanation above, the prior art of Baaijens discloses of lighting within a space (for example the meeting room as seen in Figs 1-4, 8) that is controlled based on the presence of one or more occupants and determine an activity/task (for example having task lighting off on the table 107 for an occupant working on a backlit laptop computer as seen in Fig 4; or perhaps for reading/reviewing a potential document located on the table 307 as may be seen within Fig 8; additionally, there is also a determination by the sensors of the activity being a presentation on the screen 101, 301 where the lighting may be switched off, see Paragraph 0056) of the occupants based on sensors (for example see 124, 126 and 326A-D) within the space. Once these factors have been determined, the lighting within the space is adjusted to a desired target value based on the presence and the activity/task as is claimed. 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.
