DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application is being examined under the pre-AIA first to invent provisions.
Response to Amendment
This office action is communication to response filed 12/18/2025. Claims 1, 5-8, 11-12, 15 are pending.
Response to Arguments
Applicant’s arguments with respect to claim 1, 5-8, 11-12, 15 have been considered but are not persuasive.
Regarding the 112(a) rejection, the applicant states that paragraphs for the amendment were provided and discussed in the interview to overcome the 112 rejection. The applicant states that the examiner suggested the amendment more closely reflect the specification. The applicant argues that the specification discloses electing of the intra prediction mode on the basis of direction of the neighboring blocks that have already been reconstructed (paragraph 0039) and the neighboring blocks may be blocks are already reconstructed by the intra reconstructor or that are to be reconstructed by inter reconstructor (paragraph 0057).
The examiner agrees that the examiner stated that the amendment should more closely reflect the specification. During the interview, the applicant provided paragraphs including that of the mode selector and stated these have the support for it and the examiner indicated that as long as there was support, the applicant should amend the language to be consistent with support of the specification.
In response to the arguments the examiner respectfully disagrees. The examiner notes that upon further review of the specification, the language still does not have support and is also unclear.
The specification has support for the selecting of the intra prediction mode on the basis of direction of the neighboring blocks that have already been reconstructed. The mode selector indicates selecting a mode which determines the intra mode. The applicant’s specification in paragraph 0057 as provided states “the neighboring blocks may be blocks are already reconstructed by the intra reconstructor or that are to be reconstructed by inter reconstructor. Therefore, the mode selector does not have neighboring blocks from the inter reconstructor.
The specification discloses that there are 9 intra prediction modes and there is a mode selector. There is no description of how the mode number selection with the neighboring block, which is inter-coded, determines the current intra prediction mode. The mode number selection determines the intra prediction mode.
Secondly, the specification describes that the mode selector selects a mode. The specification does not explicitly state that the mode selector selects a number (this is technically a title for a mode in the Figures). The specification states that it is selecting a mode (which is associated with a number in the Figures). The specification does not explicitly state that an intra prediction mode number is related to the neighboring block that is inter-coded. It is also noted that mode is selected based on directionality (paragraph 0064-0066 – equation 2, it does not use the inter-coded neighboring block which does not factor into the mode selection, directionality is from the pixel pairs of neighboring blocks, the coding mode of the neighboring block has no relevance on the determination of intra prediction mode).
Therefore, the specification does not have support and the specification is unclear as to how “the intra prediction mode number, in relation to the neighboring block that which is inter coded, is selected to determine the current intra prediction mode.”
The rejection is maintained.
Regarding the 112b rejection, the applicant argues that it is clear to someone of ordinary skill in the art, how the intra prediction mode number, in relation to the neighboring block that which is inter coded, is selected to determine the current intra prediction mode
In response to the arguments the examiner respectfully disagrees. The mode selector indicates selecting a mode which determines the intra mode. The applicant’s specification in paragraph 0057 as provided states “the neighboring blocks may be blocks are already reconstructed by the intra reconstructor or that are to be reconstructed by inter reconstructor. Therefore, the mode selector does not have neighboring blocks from the inter reconstructor.
It is unclear how the mode number selection with the neighboring block, which is inter-coded, determines the current intra prediction mode. The mode number selection determines the intra prediction mode.
It is unclear what the distinction between intra prediction mode and intra prediction mode number is. The mode selector selects a mode. The selection of a mode is the intra prediction mode. It is unclear what is being determined.
The rejection is maintained.
Regarding the 103 rejection, the applicant argues that Cha fails to disclose the limitation “the intra prediction mode number, in relation to the neighboring block that which is inter coded, is selected to determine the current intra prediction mode.” The applicant argues that the examiner cites from Cha Column 5, lines 54-62 which describes inter-layer prediction not inter-prediction coded block used for intra prediction.
In response to the arguments, the examiner respectfully disagrees. The examiner does not state that inter-layer prediction is used for intra prediction. The sentence provided explicitly stated neighboring blocks are inter prediction. It is noted that Figure 3 and Figure 12 were also provided (which would include any description associated with those Figures). Cha also discloses in Column 6, lines 12-15, that the neighboring blocks of the intra block would be using any prediction method as that of blocks 15 – (described Column 5, lines 58-62), and further the blocks 15 and 25 have been reconstructed. Cha also discloses a mode selection unit which would determine intra prediction modes (Column 8, lines 61-63 ) and also again neighbor block being coded using inter prediction (Column 7, lines 43-48).
The applicant’s specification does not describe how inter prediction coded block is used for intra predication with a selection of a mode number. Cha discloses selection of mode number which determines the intra prediction mode and Cha discloses neighboring blocks may be coded using inter-prediction. Cha discloses that the same neighboring blocks are used for mode selection (Figure 6). Therefore, any relation (definition as the way in which two or more concepts, objects or people are connected; a thing’s effect on or relevance to another) to a neighboring block with mode number would meet the limitation (the applicant’s specification does not give any details and does not have support for this claim limitation).
Furthermore, in KSR International Co. Teleflex Inc., 82 USPQ2d 1385, 1395 (2007), the Court found that if all the claimed elements are known in the prior art then one skilled in the art could have combined the elements as claimed by known methods with no change in their respective functions, and the combination would have yield predictable results to one of ordinary skill in the art at the time of the invention.
The rejection is maintained.
Regarding the double patenting rejection, the applicant argues that the prior art specifically Cha does not teach “the intra prediction mode number, in relation to the neighboring block that which is inter coded, is selected to determine the current intra prediction mode.”
In response to the arguments, the examiner respectfully disagrees. Please see response above for how Cha meets the limitation. The rejection is maintained.
Regarding the double patenting header, the examiner thanks the applicant for mentioning the typographical error. Claims 2-3 were inadvertently not deleted in the header as they are cancelled. The Claim numbers 2-3 were deleted from the header.
Claim Rejections - 35 USC § 112
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.
Claims 1, 5-8, 11-12, 15 are 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.
Claims 1, 5-8, 11-12, 15 recite “selecting, in relation to a neighboring block, an intra prediction mode number; using a first set of two or more mathematical expressions based on the intra prediction mode number corresponding to an intra prediction mode that has no directionality; and using a second set of the two or more mathematical expressions based on the intra prediction mode number corresponding to an intra prediction mode that has directionality…..wherein the intra prediction mode number, in relation to the neighboring block that which is inter coded, is selected to determine the current intra prediction mode.”
The specification does not describe how the intra prediction mode number selection relates to the inter-coded neighboring block to determine the intra prediction mode. The limitation “wherein the intra prediction mode number, in relation to the neighboring block that which is inter coded, is selected to determine the current intra prediction mode” requires a step of determining that is not disclosed in the specification or how the inter-coded block determines the intra prediction mode.
Secondly, the specification describes that the mode selector selects a mode. The specification does not explicitly state that the mode selector selects a number (this is technically a title for a mode in the Figures). The specification states that it is selecting a mode (which is associated with a number in the Figures). The specification does not explicitly state that an intra prediction mode number is related to the neighboring block that is inter-coded. It is also noted that mode is selected based on directionality (paragraph 0064-0066, see also equation 2, it does not use the inter-coded neighboring block which does not factor into the mode selection, the directionality is from the pixel pairs of neighboring blocks, the coding mode of the neighboring block has no relevance on the determination of intra prediction mode).
The specification has support for neighboring blocks to be reconstructed by inter reconstructor, the specification has support for selecting an intra prediction mode. The specification discloses that there are 9 intra prediction modes and there is a mode selector.
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, 5-8, 11-12, 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.
Claims 1, 5-8, 11-12, 15 recite “selecting, in relation to a neighboring block, an intra prediction mode number; using a first set of two or more mathematical expressions based on the intra prediction mode number corresponding to an intra prediction mode that has no directionality; and using a second set of the two or more mathematical expressions based on the intra prediction mode number corresponding to an intra prediction mode that has directionality…..wherein the intra prediction mode number, in relation to the neighboring block that which is inter coded, is selected to determine the current intra prediction mode.”
It is unclear how the intra prediction mode number and how the neighboring block, which is inter-coded, determines the current intra prediction mode. It is unclear what the distinction between intra prediction mode and intra prediction mode number is.
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 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 pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action:
(a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made.

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 .

Therefore, it would have been obvious to add the limitations to US 10,623,749 in order to have higher coding efficiency (Page 2, paragraph 0014) as disclosed by Kalevo and in order to have higher compression efficiency using directional intra-prediction (Column 1, lines 49-55) as disclosed by Cha.
Regarding 11 and 15, the instant application includes the additional limitations. See above for Claim 1 and 12, Kalevo discloses transmitting the bitstream (Figure 1), wherein the intra prediction mode number corresponds to an intra prediction mode that used to intra predict the neighboring block (Page 3, paragraph 0034, 0035Page 4, paragraph 0040-0041, Page 6, paragraph 0073, Figure 3A-C, Figure 4, Figure 5), further comprising: performing, for the neighboring block prior to determining the current intra prediction mode, intra-prediction using a neighboring intra prediction mode, wherein a mode number of the neighboring intra prediction mode is equal to the intra prediction mode number (Page 4, paragraph 0048, 0041-0043, Page 6, paragraph 0077-0078, Table 4, Page 10, paragraph 0143, Figure 3-5), wherein the second set comprises a mathematical expression that is not included in the first set, and the first set comprises a different mathematical expression that is not included in the second set (Page 4, paragraph 0048, 0041-0043, Page 6, paragraph 0077-0078, Table 4, Page 10, paragraph 0143, Figure 3-5), wherein the mathematical expression included in the second set and not included in the first set corresponds to an arithmetic operation between two values in order to yield a third value (Page 4, paragraph 0048, 0043, 0041, Page 6, paragraph 0077-0078, Table 4, Page 10, paragraph 0143), wherein the intra prediction mode number selected in relation to the neighboring block is represented by an integer among a plurality of predetermined integers, the plurality of predetermined integers commonly identifying intra modes available to be determined for the neighboring block and the current block, and all the intra modes available to be determined for the neighboring block are same as all the intra modes available to be determined for the current block (Page 4, paragraph 0041-0043, Figure 3-Figure 5). Therefore, it would have been obvious to add the limitations to US 10,623,749 in order to have higher coding efficiency (Page 2, paragraph 0014) as disclosed by Kalevo.
