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 .
Information Disclosure Statement
The information disclosure statements filed 01/22/2026 has been acknowledged and considered by the examiner. An initialed copy of the PTO-1449 is included in this correspondence.
Response to Arguments
Applicant's arguments filed 04/06/2026 have been fully considered but they are not persuasive. In particular, Applicant argues that cited prior arts fail to teach “a plurality of light collimators that are configured to redirect image light from the LED micro-display to be incident on the projection optics at different angles”. In response to the argument, the Office respectfully submits that Bricks discloses a collimation apparatus 7 (Figs. 1, 4, 7, 9-10, 13-16 and 18-20) provided between an array of emitters 2 and an optical imaging apparatus 10. The collimation apparatus 7 is configured to restrict an opening angle of a beam 8. Brick further teaches that the collimation apparatus 7 is configured to redirect image light from the light emitting diodes. For example, Fig.10, an input light from a light emitting diode 3 of the array 2 passes through the collimation apparatus 7. As shown in Fig.10 reproduced below, an output light 4 from the collimation apparatus 7 has a direction different from a direction of the input light. Similarly, in Fig.17, image light from the light emitting diode 3 of the array 2 is redirected (i.e., changing the direction) after passing through the collimation apparatus 7.

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.
Claims 2, 7-8, and 10-17 are rejected under 35 U.S.C. 103 as being unpatentable over Cheng et al. (US Pub 2018/0284460 A1) in view of Ahmed et al. (US Pub 2019/0335553 A1) and further in view of Brick (US Pub 2018/0299673).

The motivation would have been in order to achieve optimization of the beam guidance (Brick, para. [0119]).

Yeoh teaches a color filter (Fig.3, e.g., optical filter 392) between two neighboring waveguides of the waveguide stack of the eyepiece (Fig.3, the optical filter 392 is disposed between first neighboring waveguides 340 and 350. The optical filter 394 is disposed between second neighboring waveguides 350 and 360), wherein a first of the neighboring waveguides precedes a second of the neighboring waveguides in a light path extending from the full-color illumination system (Fig.3, the first neighboring waveguides precede the second neighboring waveguides in a light path extending from the projector subsystem 310), wherein the color filter is configured to selectively absorb light of a wavelength corresponding to a wavelength of light configured to be in-coupled by the in-coupling optical element of the first of the neighboring waveguides (para. [0030-0031], the optical filter 392 is configured to have a high transmittance value in the green and red wavelength ranges and a low transmittance value in the blue wavelength range. Therefore, image light transmitted by the first optical filter 392 and incident on the ICG 352 in the green waveguide 350 may contain primarily green image light and red image light, and very little or no blue image light. In other words, the optical filter 392 selectively absorbs blue light).

Yeoh teaches a third waveguide following the second of the neighboring waveguides in the light path; and an other color filter configured to selectively absorb light of a wavelength corresponding to a wavelength of light configured to be in-coupled by the in-coupling optical element of the second of the neighboring waveguides (para. [0030-0032], the second optical filter 394 may be configured to have a high transmittance value in the red wavelength range, and a low transmittance value in the green and blue wavelength ranges. Therefore, image light transmitted by the second optical filter 394 and incident on the ICG 362 in the red waveguide 360 may contain primarily red image light, and very little or no green image light and blue image light).
The motivation is the same as the rejection of claim 4 above.

[0057-0058], the first short-pass filter 518 may be configured to pass blue light and absorb green light, so that the green image light cross-coupled into the first waveguide 510 may be absorbed by the first short-pass filter 518).

The motivation would have been in order to prevent unwanted color light from propagating to the OPE and the EPE regions of the waveguide (Yeoh, para. [0057-0058]).

For example, a beam profile of a light beam 920 emitted from each micro-LED in micro-LED array 910 may have an HWHM (i.e., half width half magnitude) angle of, for example, about 40°).
At the time of invention was effectively filed, it would have been obvious to one of ordinary skill in the art to modify the head-mounted display system of Cheng in view of Ahmed and Brick to include the teaching of Scheller of providing an LED array having a beam profile about 40°. The motivation would have been in order to maintain the uniformity and brightness of image light (Scheller, para. [0115]).
