Information Disclosure Statement
The information disclosure statement(s) filed on 9/27/2023, 3/26/2025, 8/11/2025 have been acknowledged and considered by the examiner. Initialed copies of supplied IDS(s) forms are included in this correspondence.
Claim Objections
Claim 19 is objected to because of the following informalities:
Line 9 of the claim states “a tube lens” when it should state “the tube lens”.
Appropriate correction is required.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-21 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, 11, and 19, claims state the limitation “substantially constant” in line 4 of claim 1, line 3 of claim 11, and line 4 of claim 19. This limitation is unclear because the term “substantially constant” can encompass myriad speeds such as 20 mm/sec or 75 mph. What are the metes and bounds of these claims if they must later be clarified and limited as being greater than 20 mm/sec? Dependent claims 6 and 16 resolve this issue, however if some other meaning is attributed to “substantially constant” aside from that which is claimed in claims 6 and 16, then what is captured by this limitation beyond being greater than 20 mm/sec? Regarding the independent claims, one of ordinary skill in the art would not be apprised as to the scope of the invention (MPEP §2173.05(b) I). For purposes of compact prosecution, examiner will interpret this limitation to be greater than 20 mm/sec as stated in claims 6 and 16.
Claim 20 recites the limitation "the mirror" in lines 2 and 5 of the claim. There is insufficient antecedent basis for this limitation in the claim. This rejection could be overcome if “the mirror” is amended to say “the first mirror”.
Claim 21 recites the limitation "the mirror" in line 1 of the claim. There is insufficient antecedent basis for this limitation in the claim. This rejection could be overcome if “the mirror” is amended to say “the first mirror”.
Also, claims 2-10, 12-18, and 20-21 are rejected by virtue of their dependency.
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.

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.
Claims 8-9, 17 are rejected under 35 U.S.C. 103 as being unpatentable over Owens as applied to claims 1 and 11 above, and further in view of Arnold et. al US 20150301428 (hereinafter “Arnold”).
Regarding claim 8, Owens teaches the image capture system of claim 1, and Koyama further teaches the tube lens (17).
Owens does not specify wherein the tube lens includes a fluidic focusing device including a variable focus shift based on a variable index of refraction.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have a fluidic focusing device as taught by Arnold in the image capture system of Owens in order to control the shape of the emitted beam (Arnold para. 0196).
Regarding claim 9, Owens and Arnold teach the image capture system of claim 8, and Arnold further teaches wherein the fluidic focusing device (300) includes a tunable acoustic gradient lens (Arnold para. 0002 and 0196).
Regarding claim 17, Owens teaches the method of claim 11, and Koyama further teaches the tube lens (17).

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have a fluidic focusing device as taught by Arnold in the image capture system of Owens in order to control the shape of the emitted beam (Arnold para. 0196).
Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Owens as applied to claim 1 above, and further in view of Raghunathan US Patent 9,678,326 (hereinafter “US 326”).
Regarding claim 10, Owens teaches the image capture system of claim 1, and Owens further teaches the tube lens (Owens para. 0152).
Owens does not specify wherein the tube lens includes a digital micromirror device, however Owens does teach scanning mirrors (Owens para. 0146).
In the same field of endeavor, US 326 teaches wherein the tube lens (US 326 fig. 1 – 122, 130) includes a digital micromirror device (US 326 col. 5 lines 4-8) for the purpose of allowing different light collection angles to be selectively imaged onto the light detector (US 326 col. 5 lines 15-17). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the tube lens include a digital micromirror device as taught by US 326 in the image capture system of Owens in order to allow different light collection angles to be selectively imaged onto the light detector (US 326 col. 5 lines 15-17).

Regarding claim 18, Owens and Arnold teach the method of claim 17, and Owens further teaches the tube lens (Owens para. 0152).
Owens and Arnold do not specify wherein the tube lens includes a digital micromirror device, however Owens does teach scanning mirrors (Owens para. 0146).
In the same field of endeavor, US 326 teaches wherein the tube lens (US 326 fig. 1 – 122, 130) includes a digital micromirror device (US 326 col. 5 lines 4-8) for the purpose of allowing different light collection angles to be selectively imaged onto the light detector (US 326 col. 5 lines 15-17). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the tube lens include a digital micromirror device as taught by US 326 in the image capture system of Owens and Arnold in order to allow different light collection angles to be selectively imaged onto the light detector (US 326 col. 5 lines 15-17).
