Office Action

§102
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 Arguments With regard to the applicant arguments that Blum does not teach: A fixed lens A spectral filter With respect to independent claim 1, newly independent claims 9 and 14, and any and all depending claims, the examiner respectfully disagrees. With regard to the fixed lens Blum teaches static lenses and in [0046] likens them to a fixed lens With regard to the Spectral filter, while Blum does not use the terminology “spectral filter” he describes the workings of one in the cited paragraphs [0027-0030] by means of a sensor, detecting lighting conditions and adjusting the lens. As such the rejection is believed to be proper and has been restated below to include the new amended limitations. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-6 and 8-20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Blum (US 20140043584) herein after referred to as D1.
