DETAILED ACTION
Notice of Pre-AIA or AIA Status
1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 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 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.
Information Disclosure Statement
2. The Information Disclosure Statements (IDS) filed by Applicant on Aug 26, 2024, Sept 27, 2024 and May 13, 2025 have been received and considered. Copies of the reviewed IDS(s) are enclosed with this Office action.
Double Patenting
3. The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321 (c) or 1.321 (d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(1)(1) - 706.02(1)(3) for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321 (b).
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-l.jsp.
4. Claims 1-14 are rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 1-14 respectively of US Patent No. 12,075,021-B2.
Although the claims at issue are not identical, they are not patentably distinct from each other because Claims 1-14 of U.S. Patent No. 12,075,021 discloses all the limitations of Claims 1-14 of the current application.

5. Application claim 1 and the Patent 12,075,021 claim 1 are both drawn to the same invention, i.e., rendering and projecting images. This claim differs in scope in that application claim 1 with additional limitations, i.e., “clipping the plurality of negative intensity values of said third plurality of intensity values to zero;” “setting each intensity value in the third plurality of intensity values to the minimum of either (1) its intensity value following the clipping of the plurality of negative intensity values of said third plurality of intensity values to zero or (2) a predetermined threshold value to obtain a residual of the second color gamut; and” “calculating a vector in the first color gamut that corresponds to a white point in the predefined color gamut;” “determining a scaling factor such when the vector is scaled by the scaling factor and added to the fourth plurality of intensity values none of the fourth plurality of intensity values are negative;” “adding the vector, scaled by the scaling factor, to the fourth plurality of intensity values to generate said first plurality of intensity values” is narrow in scope than U.S. Patent claim 1. Therefore, it would have been obvious to one of ordinary in the art before the effective filing date of the claimed invention was made to modify U.S. Patent claim 1 to be narrower by adding the additional limitation, i.e., clipping the plurality of negative intensity values of said third plurality of intensity values to zero; setting each intensity value in the third plurality of intensity values to the minimum of either (1) its intensity value following the clipping of the plurality of negative intensity values of said third plurality of intensity values to zero or (2) a predetermined threshold value to obtain a residual of the second color gamut; and calculating a vector in the first color gamut that corresponds to a white point in the predefined color gamut; determining a scaling factor such when the vector is scaled by the scaling factor and added to the fourth plurality of intensity values none of the fourth plurality of intensity values are negative; adding the vector, scaled by the scaling factor, to the fourth plurality of intensity values to generate said first plurality of intensity values, so to obtain Application claim 1, as claimed.
Regarding independent claims 6 and 11, the claims are rejected under obviousness double patenting for the same rational described as Claim 1.
Allowable Subject Matter

factor and added to the fourth plurality of intensity values none of the fourth plurality
of intensity values are negative;” “adding the vector, scaled by the scaling factor, to the fourth plurality of intensity values to generate said first plurality of intensity values;” "wherein the electronic processor is further configured to: calculate drive values for the at least one spatial modulator using said first and second plurality of intensity values, said drive values defining an output gamut of the projection system;" "blend the output gamut with a native color gamut of the projection system to generate final drive values, said native color gamut being defined as a set of primaries that drives said first and second distinct sets of predefined primaries equally; and" "drive the at least one spatial modulator based on said final drive values."
