Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefore, subject to the conditions and requirements of this title.
Claims 1-15 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more nor an integration of the judicial exceptions into a practical application. The limitations, under their broadest reasonable interpretation, mathematical concepts, operations, relationships. The claimed invention merely performs point cloud data gathering, entry and decoding process on the point cloud for determining parameters of a sample entry according to some condition. See analysis below for more details.
Regarding Independent Claim 1 and its dependent claims 2-9,
Step 1 Analysis: Claim 1 is directed to a process/method, which falls within one of the four statutory categories (process, machine, manufacture or composition of matter). Please see MPEP §2106.04.
Step 2A Prong 1 Analysis: Claim 1 recites, in part:
“decoding the first sample and one or more samples that follow the first sample in decoding order, based on the obtained parameter sets,
wherein the parameter sets are obtained from either a sample entry of a track including the first sample or a predetermined sample, based on at least one of a sample entry type of the track, a presence of a sync sample box or a presence of parameter set sample group boxes.”
The limitations as drafted, are processes that, under broadest reasonable interpretation, covers the performance of the limitation in the mind which falls within the “Mathematical Concept” grouping of abstract ideas. Please see MPEP §2106.04. The limitations of:
“decoding….based on the obtained parameter sets” is a step of mathematical operation using mathematical concept and relationship to perform math on point cloud data obtained (the limitation already includes point cloud data as being already obtained and the condition on which they were obtained, merely a specification to support the decoding step).
“wherein the parameter sets …group boxes” are giving condition to which the parameter sets are being obtained based on, merely a specification to the data of which the decoding step uses, hence, still part of the decoding step which is a mathematical operation using mathematical concept and relationship.
Accordingly, the claim recites an abstract idea.
Step 2A Prong 2 Analysis: This judicial exception is not integrated into a practical application. particular, the claim recites the following additional element(s) –
“a reception apparatus of point cloud data, the method comprising:
obtaining parameter sets necessary for a random access, from the point cloud data, based on that a request for the random access from a first sample within the point cloud data is occurred”
The additional element “a reception apparatus of point cloud data” - recited at a high level of generality (of a generic apparatus for processing data).
The additional elements include steps of insignificant extra-solution/post-solution activities of data gathering, data generating, data transmitting, etc. [acquiring data/information, transmitting data/info., outputting data/information, displaying data/info., converting data/info., generating data/info., etc.].
Accordingly, these additional elements do not integrate the abstract idea into a practical application because they do not impose any meaningful limits on practicing the abstract idea. The claim as a whole is directed to an abstract idea. Please see MPEP §2106.04.(d).III.C.
Step 2B Analysis: there are no additional elements, such as for these additional elements as indicated above, that amount to significantly more than the judicial exception. Please see MPEP §2106.05. The claim is directed to an abstract idea. Please see MPEP §2106.05
For all of the foregoing reasons, claim 1 does not comply with the requirements of 35 USC 101.
Accordingly, the dependent claims 2-9 do not provide elements that overcome the deficiencies of the independent claim 1.
Moreover, claim 2 recites, in part,
“wherein, based on that the sample entry type of the track is…from the sample entry of the track.”
recites, in part, wherein clause that merely provides unlimiting further specification that provide well-known generality, high level of generality further specification limitation to the limitation each depends on, such as what the sample entry type is based on.
Moreover, claim 3 recites, in part,
“wherein, based on that the sample entry type of the track is…does not comprise the sync sample box.”
recites, in part, wherein clause that merely provides unlimiting further specification that provide well-known generality, high level of generality further specification limitation to the limitation each depends on, such as what the sample entry type is based on a condition as recited.
Moreover, claim 4 recites, in part,
“wherein, based on that the sample entry type of the track is…point cloud data comprises the sync sample box and the first sample is indicated as a sync sample.”
recites, in part, wherein clause that merely provides unlimiting further specification that provide well-known generality, high level of generality further specification limitation to the limitation each depends on, such as basing on a certain sample type, the parameters are obtained according to a condition, which is merely data gathering additional element.
Moreover, claim 5 recites, in part,
“wherein the sync sample is present…a sample entry type ‘gpeb’ or ‘gpcb’”.
recites, in part, wherein clause that merely provides unlimiting further specification that provide well-known generality, high level of generality further specification limitation to the limitation each depends on, such as specifying that the sync sample box is present according to certain rule and condition.
Moreover, claim 6 recites, in part,
“wherein the sync sample is present…does not contain geometry component”.
recites, in part, wherein clause that merely provides unlimiting further specification that provide well-known generality, high level of generality further specification limitation to the limitation each depends on, such as specifying that the sync sample box is constrained according to certain rule and condition.
Moreover, claim 7 recites, in part,
“wherein, based on that samples in a track…in an associated track are treated as sync samples”.
recites, in part, wherein clause that merely provides unlimiting further specification that provide well-known generality, high level of generality further specification limitation to the limitation each depends on, such as specifying that basing on a type of samples in a track.
Moreover, claim 8 recites, in part,
“wherein, based on that…is not indicated as the sync sample, the parameter sets are…comprises the parameter set sample group boxes”.
recites, in part, wherein clause that merely provides unlimiting further specification that provide well-known generality, high level of generality further specification limitation to the limitation each depends on, such as specifying that basing on that the point cloud data does not comprises certain information, and the parameter sets are obtained according to certain rule, condition, merely specifying the way the data being obtained.
Moreover, claim 9 recites, in part,
“wherein, based on that the point cloud data…the decoding are not performed”.
recites, in part, wherein clause that merely provides unlimiting further specification that provides well-known generality, high level of generality further specification limitation to the limitation each depends on, such as specifying a condition to what the decoding performs or not.
Accordingly, the dependent claims 1-9 are not patent eligible under 101.
Regarding independent claim 10:
The independent claim 10 recites analogous limitations to the independent claim 1, hence, is 101 ineligible for the same reasons regarding these limitations. Moreover, claim 10 further recited additional elements of “memory; and at least one processor, the processor configured to” including generic computer and computer components recited at high level of generality. Therefore, claim 10 is rejected under 101.
Regarding independent claim 11 and its dependent claims 12-14:
The independent claim 11 recites analogous limitations to the independent claim 1, hence, is 101 ineligible for the same reasons regarding these limitations. The independent claim 11, further recited additional elements of insignificant extra-solution activities of data gathering of “storing a bitstream…or more tracks”, “generating a geometry-based…on the tracks”. The dependent claims 12-14, recite analogous limitations to the dependent claims 2-9, hence are 101 ineligible under the same reasons.
Regarding independent claim 15:
The independent claim 15 recites analogous limitations to the independent claim 11, hence, is 101 ineligible for the same reasons regarding these limitations. Moreover, claim 15 further recited additional elements of “memory; and at least one processor, the processor configured to” including generic computer and computer components recited at high level of generality. Therefore, claim 15 is rejected under 101.
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 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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 1 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over Ye-Kui Wang et. al. (“US 2016/0234526 A1” hereinafter as “Wang”) in view of Lauri Ilola et. al. (“US 2020/0381022 A1” hereinafter as “Ilola”).
Regarding claim 1, Wang teaches a method performed by a reception apparatus of data (Title shows “Placement of Parameter Sets and Sync Samples in Video Coding”; moreover, Abstract discloses “file formats and parsing and coding of video data”), the method comprising: obtaining parameter sets necessary for a random access (Par. [0042] discloses “determine whether conditions associated with random access points have been satisfied for a particular bitstream, Such as conditions associated with parameter sets”), from the data (Par. [0042] discloses “a video coder may not be able to accurately and/or consistently determine whether conditions associated with random access points have been satisfied for a particular bitstream”), based on that a request for the random access (Par. [0080] discloses “router 36 may be responsible for providing coded video data to destination device 14 in a requested format”; moreover, Par. [0085] discloses “a random access point is interpreted differently by different devices (e.g., where different devices may include a device responsible for encoding/packaging video data and a device responsible for parsing/decoding video data), a file may not be delivered and/or played back properly” indicating a request for a random access) from a first sample within the data is occurred (Pars. [0088-0089] discloses “Random Access Point (RAP)…sample in a track that starts at ISAU of a SAP of type 1 or 2 or 3 as defined…informally, a sample, from which when decoding starts, the sample itself and all samples following in composition order can be correctly decoded”); and decoding the first sample (Par. [0089] discloses “informally, a sample, from which when decoding starts, the sample itself and all samples following in composition order can be correctly decoded”) and one or more samples that follow the first sample in decoding order (Par. [0045] discloses “a video decoder may decode parameter set data for the video data only in the sample entry for the sample or in a sample occurring in decoding order between the sample and a previous sample in decoding order”), based on the obtained parameter sets (Par. [0045] discloses “a video decoder may decode parameter set data for the video data only in the sample entry for the sample or in a sample occurring in decoding order”), wherein the parameter sets are obtained from either a sample entry of a track including the first sample or a predetermined sample (“or” indicates a selection, therefore, only one of the options is the instant scope of the claim, the examiner selects “a predetermined sample” which is disclosed in Par. [0084] of “parameter sets may include an SPS, PPS, or VPS... a parameter set sample may be a sample in a parameter set stream that includes parameter set NAL units that are to be considered as present in a video elementary stream at the same instance in time”), based on at least one of a sample entry type of the track (Par. [0083] discloses “a sample entry may provide a description of a corresponding sample. For example, a sample entry may include a four-character code that describes a characteristic of the corresponding sample, Such as a format of the corresponding sample. Example sample entries for AVC and SVC tracks are included”), a presence of a sync sample box or a presence of parameter set sample group boxes (“or” indicates a selection, therefore, only one of the options is the instant scope of the claim, the examiner selects “a presence of parameter set sample group boxes” which is disclosed in Par. Par. [0039] discloses “the ISOBMFF enables sample-specific metadata to be specified with various mechanisms. Specific boxes within the Sample Table box (“stbl"’) have been standardized to respond to common needs. For example, a Sync Sample box ('stss') is used to list random access samples (as described below) of the track”; [0045] of “the video decoder may determine parameter set data needed for decoding the video data of the non-sync sample only from the sample entry for the non-sync sample….For example, in the event that a sample is not a sync sample and parameter set data is included in any other location of the bitstream than those specified, the video decoder 30 may reject the file as non-conforming and may not decode the sample”).
However, Wang does not explicitly teach the data being point cloud data.
Ilola teaches the data being point cloud data (Par. [0220] discloses “accessing the point cloud compression coded bitstream. The point cloud compression coded bitstream includes a texture information bitstream, a geometry information bitstream, and an auxiliary metadata bitstream As shown in block 42, the apparatus includes means, such as the processing circuitry 12, for causing storage of the point cloud compression coded bitstream”).
Therefore, it would have been obvious to one or ordinary skill in the art before the effective filing date of the claimed invention was made to combine the teaches of Wang of having a method performed by a reception apparatus of data, the method comprising: obtaining parameter sets necessary for a random access, from the data, based on that a request for the random access from a first sample within the data is occurred; and decoding the first sample and one or more samples that follow the first sample in decoding order, based on the obtained parameter sets, wherein the parameter sets are obtained from either a sample entry of a track including the first sample or a predetermined sample, based on at least one of a sample entry type of the track, a presence of a sync sample box or a presence of parameter set sample group boxes, with the teachings of Ilola of having the data being point cloud data.
Wherein having Wang’s method of having the data being point cloud data.
The motivation behind the modification would have been to improve coding efficiency by having parameter set including relevant information in appropriate placement for such coding, and further to improve coding compression with considering point cloud data information such as temporal data and geometry data for increased coding efficiency. Since both Wang and Ilola perform data compression and storing for efficient random access. Wherein Wang’s system improves coding efficiency by having parameter set including relevant information in appropriate placement for such coding (see Wang’s Par. [0061]), and Ilola’s system improves coding compression with considering point cloud data information such as temporal data and geometry data for increased coding efficiency (see Ilola’s Par. [0186]).
Regarding claim 10, Wang teaches a reception apparatus of data, the apparatus comprising (Title shows “Placement of Parameter Sets and Sync Samples in Video Coding”; moreover, Abstract discloses “file formats and parsing and coding of video data”): memory; and at least one processor, the processor configured to (Par. [0014] discloses “a non-transitory computer-readable medium comprises instructions stored thereon that, when executed, cause one or more processors…”): obtain parameter sets necessary for a random access (Par. [0042] discloses “determine whether conditions associated with random access points have been satisfied for a particular bitstream, Such as conditions associated with parameter sets”), from the data (Par. [0042] discloses “a video coder may not be able to accurately and/or consistently determine whether conditions associated with random access points have been satisfied for a particular bitstream”), based on that a request for the random access (Par. [0080] discloses “router 36 may be responsible for providing coded video data to destination device 14 in a requested format”; moreover, Par. [0085] discloses “a random access point is interpreted differently by different devices (e.g., where different devices may include a device responsible for encoding/packaging video data and a device responsible for parsing/decoding video data), a file may not be delivered and/or played back properly” indicating a request for a random access) from a first sample within the data is occurred (Pars. [0088-0089] discloses “Random Access Point (RAP)…sample in a track that starts at ISAU of a SAP of type 1 or 2 or 3 as defined…informally, a sample, from which when decoding starts, the sample itself and all samples following in composition order can be correctly decoded”); and decode the first sample (Par. [0089] discloses “informally, a sample, from which when decoding starts, the sample itself and all samples following in composition order can be correctly decoded”) and one or more samples that follow the first sample in decoding order (Par. [0045] discloses “a video decoder may decode parameter set data for the video data only in the sample entry for the sample or in a sample occurring in decoding order between the sample and a previous sample in decoding order”), based on the obtained parameter sets (Par. [0045] discloses “a video decoder may decode parameter set data for the video data only in the sample entry for the sample or in a sample occurring in decoding order”), wherein the parameter sets are obtained from either a sample entry of a track including the first sample or a predetermined sample (“or” indicates a selection, therefore, only one of the options is the instant scope of the claim, the examiner selects “a predetermined sample” which is disclosed in Par. [0084] of “parameter sets may include an SPS, PPS, or VPS... a parameter set sample may be a sample in a parameter set stream that includes parameter set NAL units that are to be considered as present in a video elementary stream at the same instance in time”), based on at least one of a sample entry type of the track (Par.

However, Wang does not explicitly teach the data being point cloud data.
Ilola teaches the data being point cloud data (Par. [0220] discloses “accessing the point cloud compression coded bitstream. The point cloud compression coded bitstream includes a texture information bitstream, a geometry information bitstream, and an auxiliary metadata bitstream As shown in block 42, the apparatus includes means , such as the processing circuitry 12, for causing storage of the point cloud compression coded bitstream”).
Therefore, it would have been obvious to one or ordinary skill in the art before the effective filing date of the claimed invention was made to combine the teaches of Wang of having a reception apparatus of point cloud data comprising instructions to obtain parameter sets necessary for a random access, from the data, based on that a request for the random access from a first sample within the data is occurred; and decode the first sample and one or more samples that follow the first sample in decoding order, based on the obtained parameter sets, wherein the parameter sets are obtained from either a sample entry of a track including the first sample or a predetermined sample, based on at least one of a sample entry type of the track, a presence of a sync sample box or a presence of parameter set sample group boxes, with the teachings of Ilola of having the data being point cloud data.
Wherein having Wang’s method of having the data being point cloud data.
The motivation behind the modification would have been to improve coding efficiency by having parameter set including relevant information in appropriate placement for such coding, and further to improve coding compression with considering point cloud data information such as temporal data and geometry data for increased coding efficiency.

[0186]).
Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Ye-Kui Wang et. al. (“US 2016/0234526 A1” hereinafter as “Wang”) in view of Lauri Ilola et. al. (“US 2020/0381022 A1” hereinafter as “Ilola”) and Yaxian Bai et. al. (“US 2022/0366611 A1” hereinafter as “Bai”).
Regarding claim 2, Wang in view of Ilola teaches the method of claim 1, Wang teaches the parameter sets are obtained from the sample entry of the track (Par. [0205] discloses “video decoder 30 may be configured to decode parameter set data for non-sync samples only from a sample entry associated with”).
However, Wang in view of Ilola does not explicitly teach wherein, based on that the sample entry type of the track is 'gpel' or 'gpcl'.
Bai teaches wherein, based on that the sample entry type of the track is 'gpel' or 'gpcl' (“or” indicates a selection, therefore, only one of the options is the instant scope of the claim, the examiner selects “gpcl” which is disclosed in Par. [0088] discloses “mandatory : One of ‘ gpel , “ gpeg ' , ' gpcl , ‘ gpcg ’ , ' gpes ” , “ gpcs ’ , ‘ gpei ' and ' gpci ' sample entry is mandatory”; furthermore, Pars. [0094-0096] disclose “the sample entry of type ‘gpcl' is further extended to indicate spatial scalability functionality of G - PCC data . When the decoder is to decode and render a point cloud with its LoD”).
Therefore, it would have been obvious to one or ordinary skill in the art before the effective filing date of the claimed invention was made to combine the teaches of Wang in view of Ilola of having a method performed by a reception apparatus of data, the method comprising: obtaining parameter sets necessary for a random access, from the data, based on that a request for the random access from a first sample within the data is occurred; and decoding the first sample and one or more samples that follow the first sample in decoding order, based on the obtained parameter sets, wherein the parameter sets are obtained from either a sample entry of a track including the first sample or a predetermined sample, based on at least one of a sample entry type of the track, a presence of a sync sample box or a presence of parameter set sample group boxes, the parameter sets are obtained from the sample entry of the track, with the teachings of Bai of having wherein, based on that the sample entry type of the track is 'gpel' or 'gpcl'.
Wherein having Wang’s method of having wherein, based on that the sample entry type of the track is 'gpel' or 'gpcl'.
The motivation behind the modification would have been to improve coding efficiency by having parameter set including relevant information in appropriate placement for such coding, and further to improve point cloud compression processing for dynamically varying point clouds with different entry types for an efficient compress method. Since both Wang and Bai perform data compression and storing for efficient random access.

[0080] discloses “router 36 may be responsible for providing coded video data to destination device 14 in a requested format”; moreover, Par. [0085] discloses “a random access point is interpreted differently by different devices (e.g., where different devices may include a device responsible for encoding/packaging video data and a device responsible for parsing/decoding video data), a file may not be delivered and/or played back properly” indicating a request for a random access) from a first sample within the data (Pars. [0088-0089] discloses “Random Access Point (RAP)…sample in a track that starts at ISAU of a SAP of type 1 or 2 or 3 as defined…informally, a sample, from which when decoding starts, the sample itself and all samples following in composition order can be correctly decoded”) are included in either a sample entry of a track including the first sample or a predetermined sample (“or” indicates a selection, therefore, only one of the options is the instant scope of the claim, the examiner selects “including the first sample” which is disclosed in Par. [0089] of “informally, a sample, from which when decoding starts, the sample itself and all samples following in composition order can be correctly decoded”; Par. [0045] discloses “a video decoder may decode parameter set data for the video data only in the sample entry for the sample or in a sample occurring in decoding order between the sample and a previous sample in decoding order”), based on at least one of a sample entry type of the track (Par. [0083] discloses “a sample entry may provide a description of a corresponding sample. For example, a sample entry may include a four-character code that describes a characteristic of the corresponding sample, Such as a format of the corresponding sample. Example sample entries for AVC and SVC tracks are included”), a presence of a sync sample box or a presence of parameter set sample group boxes (“or” indicates a selection, therefore, only one of the options is the instant scope of the claim, the examiner selects “a presence of parameter set sample group boxes” which is disclosed in Par. Par. [0039] discloses “the ISOBMFF enables sample-specific metadata to be specified with various mechanisms. Specific boxes within the Sample Table box (“stbl’) have been standardized to respond to common needs. For example, a Sync Sample box ("stss') is used to list random access samples (as described below) of the track”; [0045] discloses “the video decoder may determine parameter set data needed for decoding the video data of the non-sync sample only from the sample entry for the non-sync sample….For example, in the event that a sample is not a sync sample and parameter set data is included in any other location of the bitstream than those specified, the video decoder 30 may reject the file as non-conforming and may not decode the sample”).
However, Wang does not explicitly teach the data being point cloud data.

The point cloud compression coded bitstream includes a texture information bitstream, a geometry information bitstream, and an auxiliary metadata bitstream As shown in block 42, the apparatus includes means , such as the processing circuitry 12, for causing storage of the point cloud compression coded bitstream”).

[0100] discloses “when the coded G-PCC geometry data and the coded G-PCC attribute data are stored in separate tracks… Carriage of Geometry-based Point Cloud Compression Data”) based on the tracks (Par. [0099] discloses “when the G-PCC data file is carried in a single track, the G-PCC encoded data is represented by a single track declaration. Single-track encapsulation of G-PCC data may utilize a simple ISOBMFF encapsulation by storing the G-PCC data file in a single track without further processing”).
