Response to Arguments / Amendments
Applicant’s arguments have been fully considered, but they are not persuasive, see discussion below.
Rejections under 35 U.S.C. § 102:
The applicant argued that Gudumasu fails to anticipate at least the features of "wherein, based on the track being a temporal level track, the highest temporal level identifier value is determined as a highest value among temporal level identifiers present in a scalability information box," as recited in amended claim 1.
As to the above argument, Gudumasu discloses the highest temporal level identifier value is determined as a highest value among temporal level identifiers present in a scalability information box by selecting the maximum number of temporal layers to be present in the G-PCC data file to support temporal scalability and distributes the G-PCC frames in the data file to multiple temporal layers (([0275]).
Gudumasu also discloses metadata for each track includes a list of sample description entries, each providing the coding or encapsulation format used in the track and the initialization data for processing that format. Each sample is associated with one of the sample description entries of the track. … Each entry sets forth part of the track time-line by mapping part of the composition timeline or by indicating ‘empty’ time, for example, portions of the presentation timeline that map to no media, also known as an ‘empty’ edit such as shown in the table below ([0097]).

Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1, 4 & 6-8 are rejected under 35 U.S.C. 102(a) (2) as being anticipated by Gudumasu et al. (US 20230281923, hereinafter Gudumasu).
Regarding Claim 1, Gudumasu discloses a method performed by a reception device of point cloud data, the method comprising:
obtaining a geometry-based point cloud compression (G-PCC) file including the point cloud data ([0106], FIG. 7, data for a geometry-based point cloud compression GPCC item 702 for three G-PCC tiles is carried in three tile items by storing each G-PCC tile in a separate tile item 704, 706, 708); and
obtaining a sample group description box with a predetermined group type from the G-PCC file ([0117]-[0119], A G-PCC tile track is identified by a GPCCTileSampleEntry sample description. The sample entry type for a G-PCC geometry or attribute tile track is ‘gpt1’ with Sample Entry Type: ‘gpt1’ and Sample Description Box (‘stsd’));
wherein, based on the sample group description box being present in a track in the G-PCC file ([0112], G-PCC base track uses a GPCCSampleEntry with a sample entry type of ‘gpcb’when the G-PCC data file contains multiple tiles and the tile data is carried in geometry tile tracks and attribute tile tracks ), an entry count in the sample group description box is equal to a value obtained by adding 1 to a highest temporal level identifier value included in the track ([0275], [0312], select the maximum number of temporal layers to be present in the G-PCC data file to support temporal scalability and distributes the G-PCC frames in the data file to multiple temporal layers; and temporal level sample group ‘tele’ indicates a TemporalId value and the sample with temporal level TemporalId is mapped to the sample group description index TemporalId+1 (adding 1 to a highest temporal level identifier); [0366]); and
wherein, based on the track being a temporal level track, the highest temporal level identifier value is determined as a highest value among temporal level identifiers present in a scalability information box([0275], select the maximum number of temporal layers to be present in the G-PCC data file to support temporal scalability and distributes the G-PCC frames in the data file to multiple temporal layers; [0097], metadata for each track includes a list of sample description entries, each providing the coding or encapsulation format used in the track and the initialization data for processing that format. Each sample is associated with one of the sample description entries of the track. … Each entry sets forth part of the track time-line by mapping part of the composition timeline or by indicating ‘empty’ time, for example, portions of the presentation timeline that map to no media, also known as an ‘empty’ edit such as shown in the table below;

wherein, based on the track being a temporal level tile track, the highest temporal level identifier value is determined based on whether a tile scalability information box is present in the temporal level tile track ([0275], select the maximum number of temporal layers to be present in the G-PCC data file to support temporal scalability and distributes the G-PCC frames in the data file to multiple temporal layers; [0097], metadata for each track includes a list of sample description entries, each providing the coding or encapsulation format used in the track and the initialization data for processing that format. Each sample is associated with one of the sample description entries of the track. … Each entry sets forth part of the track time-line by mapping part of the composition timeline or by indicating ‘empty’ time), and
wherein, based on the tile scalability information box not being present in the temporal level tile track, the highest temporal level identifier value is determined as a highest value among temporal level identifiers present in a scalability information box in a tile base track, and wherein the tile base track references the temporal level tile track ([0366], A maximum number of temporal layers present in a data file including the timed-metadata track may be identified in the data file. A geometry tile track may signal at least one temporal layer identifier of G-PCC samples present in the geometry tile track. A samples of a G-PCC component of a geometry tile track may be grouped based on temporal level of each sample; [0097], metadata for each track includes a list of sample description entries, each providing the coding or encapsulation format used in the track and the initialization data for processing that format. Each sample is associated with one of the sample description entries of the track. … Each entry sets forth part of the track time-line by mapping part of the composition timeline or by indicating ‘empty’ time).
Regarding Claim 4, Gudumasu discloses the method of claim 3, wherein, based on the tile scalability information box being present in the temporal level tile track, the highest temporal level identifier value is determined as a highest value among temporal level identifiers present in the tile scalability information box ([0366], A maximum number of temporal layers present in a data file including the timed-metadata track may be identified in the data file. A geometry tile track may signal at least one temporal layer identifier of G-PCC samples present in the geometry tile track. A samples of a G-PCC component of a geometry tile track may be grouped based on temporal level of each sample; [0097], metadata for each track includes a list of sample description entries, each providing the coding or encapsulation format used in the track and the initialization data for processing that format. Each sample is associated with one of the sample description entries of the track. … Each entry sets forth part of the track time-line by mapping part of the composition timeline or by indicating ‘empty’ time).
Regarding Claim 6, Gudumasu discloses the method of claim 1, wherein, based on a predetermined box being present in a temporal level tile track, the entry is identified based on a value of a sample group description index ([0312], temporal level sample group ‘tele’ indicates a TemporalId value and the sample with temporal level TemporalId is mapped to the sample group description index TemporalId+1 (adding 1 to a highest temporal level identifier); [0366]).
