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 .
Examiner’s Note
Examiner has cited particular paragraphs/columns and line numbers or figures in the references as applied to the claims below for the convenience of the applicant. Although the specified citations are representative of the teachings in the art and are applied to the specific limitations within the individual claim, other passages and figures may apply as well. It is respectfully requested from the applicant, in preparing the responses, to fully consider the references in entirety as potentially teaching all or part of the claimed invention, as well as the context of the passage as taught by the prior art or disclosed by the examiner. Applicant is reminded that the Examiner is entitled to give the broadest reasonable interpretation to the language of the claims. Furthermore, the Examiner is not limited to Applicants’ definition which is not specifically set forth in the claims.
Response to Amendment
The amendment filed 11/25/2025 has been entered. Claims 1-15 remain pending in the application. Applicant’s amendments to the Claims have overcome each and every objection and rejection under U.S.C. 112 previously set forth in the Office Action mailed 8/28/2025.
Response to Arguments
Applicant's arguments filed 11/25/2025 have been fully considered but they are not persuasive. The argument is moot as it is not based on the claims as examined in the office action mailed 8/28/2025 but rather on the amended claims submitted 11/25/2025. The applicant’s cited limitations to argue against the rejection, such as “and wherein the light source and the one or more sensors are positioned on opposite sides of the solar panels such that the one or more sensors are configured to detect the amount of light passing through the solar panels and wherein the indication is related to the amount of light passing through the solar panels” are part of amendments added to the claim after mailing of the office action, and therefore not present for the previous examination and rejection. See updated rejection of the claims below.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 1 and 6 are rejected under 35 U.S.C. 103 as being unpatentable over Sun (US 20170036246), herein after referred to as Sun, in view of Sela (US 20110265840), herein after referred to as Sela.

As a simplistic example, if the artificial illuminator is configured to emit light at an X intensity level, and the voltage generated by photovoltaic cell 50 in response to the illumination is 0.8.times., the efficiency reduction due to dirt is 20%.”)
