DETAILED ACTION
1. The communication is in response to the application received 07/01/2025, wherein claims 1-20 are pending and are examined as follows. This application is a continuation of Parent Application No. 17/471,064 (now U.S. Patent No. 12,363,324 B2).
Notice of Pre-AIA or AIA Status
2. 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
3. The information disclosure statements (IDS) were submitted on 07/02/2025 and 05/07/2026. The submissions are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner.
Examiner’s notes
4. For the same reasons presented in the Notice of Allowance (03/14/2025) for Parent Application 17/471,064 (now U.S. Patent No. 12,363,324 B2), the closest prior art (notably Hannuksela, Skupin, and Rapaka) do not reasonably teach and/or suggest, either alone or in combination, all of the disclosed features of the instant claims given their broadest reasonable interpretation (BRI). As such, no prior art rejections have been made.
Claim Rejections - 35 USC § 112
5. The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claim 4 is rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
Regarding claim 4, claim 4 recites “wherein mixed_nalu_types_in_pic_flag is set to one to indicate the picture contains exactly two NAL unit types.” (emphasis added). However, the specification does not appear to disclose and/or suggest this feature. At most, the specification shows that said flag is set to one, when specifying that each picture referring to the PPS has more than one VCL NAL unit and the VCL NAL units do not have the same value of NAL unit type (nal_unit_type). See for e.g. ¶0011. This is also recited in claim 3. However, there does not seem to be any indication of the picture containing exactly two NAL unit types, as claimed. For the purposes of examination, the aforementioned limitation is construed to be similar to what is found in the specification as noted above.
Double Patenting
6. 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 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); 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(l)(1) - 706.02(l)(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.

7. Claims 1-4, 8-11, and 14-17 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-4 of U.S. Patent No. 12,363,324 B2, hereinafter referred to as 324. Although the claims at issue are not identical, they are not patentably distinct from each other because the patented claims of 324 anticipate the instant claims of this application, where both are directed to mixed NAL unit type picture constraints. Please refer to table 1 below which illustrates the mapping between both claim sets.
8. Claims 5, 7, 12, 18, and 20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of 324 in view of Hendry et al. WO 2015/142725 A1, hereinafter referred to as Hendry. By way of Hendry’s teachings, a means for clarifying whether the End of Sequence (EOS) NAL unit for multi-layer bitstreams (e.g. SHVC) applies to a particular layer, or some or all layers can be attained (e.g.¶ 00190).
9. Claims 6, 13, and 19 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of 324 in view of Deshpande US 9,807,421 B2, hereinafter referred to as Deshpande. In light of Deshpande’s teachings, lower coding complexity can be realized for higher coding efficiency along with the requirements for increased image quality and image resolution (col. 1 lines 27-40). Please see obviousness rationale below.
10. Claims 1, 3-4, 8, 10-11, 14, and 16-17 are further rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 2, 4, 5, and 6 of U.S. Patent No. 12,192,490 B2, hereinafter referred to as 490. Although the claims at issue are not identical, they are not patentably distinct from each other because the patented claims of 490 anticipate the instant claims of this application, where both are directed to mixed NAL unit type picture constraints. Please refer to table 2 below which illustrates the mapping between both claim sets.
11. Claims 5, 7, 12, 18, and 20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 2, 4, 5, and 6 of 490 in view of Hendry. By way of Hendry’s teachings, a means for clarifying whether the End of Sequence (EOS) NAL unit for multi-layer bitstreams (e.g. SHVC) applies to a particular layer, or some or all layers can be attained (e.g.¶ 00190). Please note the obviousness rationale is the same as that presented for 324 above.
12. Claims 6, 13, and 19 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 2, 4, 5, and 6 of 490 in view of Deshpande. In light of Deshpande’s teachings, lower coding complexity can be realized for higher coding efficiency along with the requirements for increased image quality and image resolution (col. 1 lines 27-40). Please note the obviousness rationale is the same as that presented for 324 above.
13. Claims 1, 8, and 14 are also provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 2, 4, 5, and 6 of copending Application No. 18/960,730 (reference application), hereinafter referred to as 730. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of 730 anticipate the instant claims of this application, where both are directed to mixed NAL unit type picture constraints. Since 730 is a continuation of 490 (above), the claims are similar to those presented in table 2 below. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.

Obviousness rationale:
Regarding claims 5, 12, and 18, they all recite “wherein the picture is denoted as current picture (CurrPic).” Although denoting a picture as a current picture in the field of video coding is within the level of skill in the art, Hendry teaches and/or suggests throughout the disclosure various instances of a current picture (e.g. ¶00161). In light of the foregoing, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify 324 to add the teachings of Hendry as above in order to clarify whether the End of Sequence (EOS) NAL unit for multi-layer bitstreams (e.g. SHVC) applies to a particular layer, or some or all layers (e.g.¶ 00190).
Regarding claims 7 and 20, they recite “wherein the PPS contains parameters that apply to an entire picture.” Although the PPS is known in the field of video coding to contain parameters that apply to an entire picture, Hendry discloses this feature in for e.g. ¶0048. The motivation for including Hendry is the same as that presented for claims 5, 12, and 18 above.
Regarding claims 6, 13, and 19, they all recite “wherein the PPS is included in a PPS NAL unit type (PPS_NUT).” Since 324 does not address this feature, Deshpande is relied on, where table 1 in col. 13 discloses a PPS NAL unit type (PPS_NUT). In light of the foregoing, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify 324 to add the teachings of Deshpande as above to realize lower coding complexity for a higher coding efficiency along with increased image quality and image resolution (col. 1 lines 27-40).
