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 § 112
Claim 1-15 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Regarding claims 1 and 12, these claims recites the features of “a display comprising a plurality of structures in a regular arrangement, … wherein the display is configured to scatter a portion of radiation emitted by the radiation-emitting device with an intensity profile defined by the regular arrangement, the intensity profile having a first region of peak intensity extending along at least a second axis different to the first axis”. While the specification discloses (page 9, line 30-page 10, line 5) that a display comprises a plurality of structures in a regular arrangement such as radiation-emitting structures, e.g. pixels, and that the structures are periodically arranged in a regular grid, and that it has been observed that radiation incident upon such a display is scattered and/or reflected with a distinct profile, i.e. the regular arrangement of structures forming the display may effectively act as a reflective and/or transmissive grating, producing reflected and/or scattered light characterized by a defined interference pattern. However, it is unclear with what kind of regular arrangement such interference patter is achieved. Furthermore, it is not explained how it is achieved that such interference pattern has first region of peak intensity extending along at least a second axis. Clarification is required.
Regarding claim 9, this claim recites the limitation of “when dependent on claim 5 also the second region of peak intensity”. It is unclear how this limitation is related to the remaining recitations of claim 9. Does claim 9 depend on claims 1 and 5? It doesn’t appear to be a multiple dependent claim since claim 9 does not refer back in the alternative only. Clarification is required.
Claims not specifically mentioned above are rejected by virtue of their dependency on a rejected claim.
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) 1-15 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Xiang et al (US 2021/0255668).
Regarding claim 1, as far as the claim is understood, Xiang et al discloses a device (electronic device; paragraph 19) comprising: a display comprising a plurality structures in a regular arrangement (display with conductive traces such as source/drain lines, gate lines, anodes; paragraphs 25, 71; Fig.6b, “600”); and a radiation-sensitive device and a radiation-emitting device arranged on a first axis (under-display optical transceiver with optical transmitter and optical receiver; paragraphs 25, 71, 72; Figs.6A-6B, “602”, “604”); wherein the display is configured to scatter a portion of radiation emitted by the radiation-emitting device with an intensity profile defined by the regular arrangement, the intensity profile having a first region of peak intensity extending along at least a second axis different to the first axis (suppression of optical crosstalk in a direction orthogonal or a 45 degree diagonal to the first direction, in which the source/drain lines extend; paragraphs 71, 72; Figs.6a-6B, “XT suppression”).
Regarding claims 12-15, the method steps therein are inherently disclosed by the device of Xiang et al.
Regarding claims 2-5, the limitations therein are disclosed in paragraphs 71-72 of Xiang et al (i.e. suppression of optical crosstalk in a direction orthogonal or a 45 degree diagonal to the first direction, in which the source/drain lines extend; Figs.6a-6B, “XT suppression”).
Regarding claim 6, Xiang et al discloses that underdisplay optical transceiver with optical transmitter and optical receiver (Fig.2A, “232”, “234”; Figs.6A-6B, “602”, “604”).
Regarding claim 7, the limitations therein are disclosed in paragraph 19 of Xiang et al.
Regarding claims 8-9, as far as the claim is understood, the limitations therein are disclosed in paragraphs 25 and 71 of Xiang et al (Fig.6B, “600”).
Regarding claim 10, the limitations therein are disclosed in paragraph 21 of Xiang et al.
Regarding claim 11, the limitations therein are disclosed in paragraphs 47-48 of Xiang et al (Fig.2A, “232”, “234”, “236”).
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Barel et al (US 2022/0336560) is cited for disclosing a positioning proximity sensor.
