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 .
Claims 1 – 16 are presented for examination.
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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1-4, 7-9 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Niederloehner et al. (US 2016/0025869 A1; pub. Jan. 28, 2016).
Regarding claim 1, Niederloehner et al. disclose: A detection system, comprising: a semiconductor layer for converting photons or particles into charge carriers (fig.1 item 14, para. [0038]-[0039])); and a light emitting layer for generating light from the charge carriers (fig.1 item 12, para. [0038]-[0039])).
Regarding claim 2, Niederloehner et al. disclose: the semiconductor layer coverts x-rays into the charge carriers (para. [0038]-[0039])).
Regarding claim 3, Niederloehner et al. disclose: the semiconductor layer is amorphous selenium (a-Se), GaAs, CdZnTe, CdTe, or perovskite crystal (ABX3) (para. [0004]).
Regarding claim 4, Niederloehner et al. disclose: the light emitting layer is an organic light emitting diode (OLED), GaAs, AlGaAs, InGaAs, CdTe or CdZnTe (para. [0025]).
Regarding claim 7, Niederloehner et al. disclose: A detection method, comprising: converting photons or particles into charge carriers in a semiconductor layer; and generating light from the charge carriers (the claim is rejected on the same basis as claim 1).
Regarding claim 8, Niederloehner et al. disclose: the semiconductor layer coverts x-rays into the charge carriers (para. [0004] describes the same materials as that claimed in claim 3).
Regarding claim 9, Niederloehner et al. disclose: the semiconductor layer is amorphous selenium (a-Se), GaAs, CdZnTe, CdTe, or perovskite crystal (ABX3) (para. [0004]).
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
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 5-6, 10-11, 14 are rejected under 35 U.S.C. 103 as being unpatentable over Niederloehner et al. (US 2016/0025869 A1; pub. Jan. 28, 2016) in view Schwarzman et al. (US 2014/0070109 A1; pub. Mar. 13, 2014).

[0022]).
In light of the benefits for improved response time of the detector, energy and spatial resolution, stability and homogeneity of the multi-pixel detector response, increase the signal-to-noise ratio, and decrease the cross talks, without sufficiently increasing thermal noise and dark current as taught Schwarzman et al., it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Niederloehner et al. with the teachings Schwarzman et al.

[0022]).
In light of the benefits for improved response time of the detector, energy and spatial resolution, stability and homogeneity of the multi-pixel detector response, increase the signal-to-noise ratio, and decrease the cross talks, without sufficiently increasing thermal noise and dark current as taught Schwarzman et al., it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Niederloehner et al. with the teachings Schwarzman et al. to have a reflective layer, a Bragg grating, a surface structure, and/or microlens between the semiconductor layer and the light emitting layer.
