Office Action

§102 §Other
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 § 102 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, 9, 10 is/are rejected under 35 U.S.C. 102a1 as being anticipated by Hiramoto et al. (U.S. PGPUB 2014/0078355). Regarding claims 1, 9, Hiramoto et al. disclose (Figs. 6a-6c) an image sensor comprising: a two-dimensional pixel array in which a plurality of pixels including photoelectric conversion elements (2a-2d) are arranged in a form of an array on a substrate; a transparent layer (6a) formed on the two-dimensional pixel array; and a two-dimensional spectroscopic element array in which a plurality of spectroscopic elements (1a-1d) are arranged in the form of an array inside or on the transparent layer, wherein each of the spectroscopic elements includes a plurality of microstructures (micro prisms are made up of microstructures, e.g. molecules, crystalline structures, etc. ) made of a material having a refractive index that is higher ([0106]) than a refractive index of the transparent layer, the plurality of microstructures have a microstructure pattern (patterned to yield a diffractive/dispersive effect), adjacent spectroscopic elements in a two-dimensional array direction (left/right and up/down) in the two-dimensional spectroscopic element array have no translation symmetry (each split light differently), and each of the spectroscopic elements splits incident light in two-dimensional directions (left, down, right; the directions form a plane), and the plurality of pixels detect the light split in the two-dimensional directions. Hiramoto et al. also disclose (Fig. 3) an image capture optical system (12) for forming an optical image on an image capture plane of the image sensor; and a signal processing unit (13, 400) configured to process an electrical signal output by the image sensor. Regarding claim 10, Hiramoto et al. disclose (Figs. 6a-6c) a two-dimensional spectroscopic element array in which a plurality of spectroscopic elements (1a-1d) are arranged in a form of an array inside or on a transparent layer (6a), wherein each of the spectroscopic elements includes a plurality of microstructures (micro prisms are made up of microstructures, e.g. molecules, crystalline structures, etc.) made of a material having a higher ([0106]) refractive index than a refractive index of the transparent layer, the plurality of microstructures have a microstructure pattern (patterned to yield a diffractive/dispersive effect), adjacent spectroscopic elements in a two-dimensional array direction (left/right and up/down) in the two-dimensional spectroscopic element array have no translation symmetry (each split light differently), and each of the spectroscopic elements splits incident light in two-dimensional directions (left, down, right; the directions form a plane). Allowable Subject Matter Claims 2-8 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to THANH LUU whose telephone number is (571)272-2441. The examiner can normally be reached 9AM-5:30PM. Examiner interviews are available via telephone, in-person, and video conferencing using a USPTO supplied web-based collaboration tool. To schedule an interview, applicant is encouraged to use the USPTO Automated Interview Request (AIR) at http://www.uspto.gov/interviewpractice. If attempts to reach the examiner by telephone are unsuccessful, the examiner’s supervisor, Georgia Epps can be reached at 571-272-2328. The fax phone number for the organization where this application or proceeding is assigned is 571-273-8300.
