Office Action

§101 §102
CTNF 18/854,402 CTNF 78781 The DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia 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 The information disclosure statement (IDS) submitted on 10/4/2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement has been considered by the examiner. Election/Restrictions 08-05 AIA Claim s 1-11, 14 and 16 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected species , there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 4/2/2026 . 08-25 AIA Applicant's election with traverse of Group II ( Claims 12 and 17 ) in the reply filed on 4/2/2026 is acknowledged. The traversal is on the ground(s) that there is no serious search burden . This is not found persuasive because as indicated in the restriction requirement, the two inventions are classified in the server side of a video network, wherein the media data is encapsulated by generating subsamples ( see H04N 21/23109 ) and the client side of a video network, wherein the media file is received and decoded ( see H04N 21/435 ). Therefore, while the structure of the data is the same, the devices, where they reside in a video network and how the encoding and decoding process is performed by each device are separate and distinct. As stated in the restriction requirement, the Examiner has provided the two separate classifications and noted the three ways of showing serious burden ( separate classification, separate status in the art and a different field of search ). The Examiner notes that these three requirements ( not only one ) has been met . The requirement is still deemed proper and is therefore made FINAL. Claim Objections 07-29-01 AIA Claim s 12 and 17 is objected to because of the following informalities: The claim recites “a reference to at least one subsample’s property or a subsample’s property”. This recitation is redundant and recites the same property twice . Appropriate correction is required. Claim Rejections - 35 USC § 101 07-04-01 AIA 07-04 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 therefor, subject to the conditions and requirements of this title. Claims 1-20 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., a law of nature, a natural phenomenon, or an abstract idea) without significantly more. Claims 12 and 17 are directed to processing received information ( see Electric Power Group, LLC v. Alston S.A., Alstom Grid INC., Psymetrix LTD., Alstom Limited, 2015-1778 ). In regards to step 2A, the claims are clearly focused on the combination of those abstract-idea processes. The advance they purport to make is a process of gathering and analyzing information of a specified content and not any particular assuredly inventive technology directed to an abstract idea. The claims limitations can be performed using pencil and paper ( see in re Bilski ). In regards to step 2B, the claims further do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the claims do not go beyond requiring the gathering, analysis, and display of available information in a particular filed, stating those functions in general terms, without limiting them to technical means for performing the functions that are arguably an advance over conventional computer and network technology. Limiting the claims to the particular technological environment of data collection and processing, without more, insufficient to transform them into patent-eligible applications of the abstract idea at their core ( see Alice, 134 S. Ct. at 2358; Mayo, 132 S. Ct. at 1294; Bilski v. Kappos, 561 U.S. 593 ). Merely selecting information, by content or source, for collection and analysis does nothing significant to differentiate a process from ordinary mental processes, whose implicit exclusion from § 101 undergirds the information-based category of abstract ideas. Inquiry then must turn to any requirements for how the desired result is achieved. In the instant application, the claims' invocation of a processor does not transform the claimed subject matter into patent-eligible applications. The claims at issue do not require any non-conventional computer, network, or display components, or even a “non-conventional and non-generic arrangement of known, conventional pieces,” but merely call for performance of the claimed information collection and analysis functions “on a set of generic computer components” and display devices ( Bascom, 2016 WL 3514158, at *6-7 ). Claim Rejections - 35 USC § 102 07-07-aia AIA 07-07 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 – 07-08-aia AIA (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. 07-15 AIA Claim s 12 and 17 are rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by Aksu et al. (U.S. Patent Application Publication 2021/0105492) . Referring to claim 12, Aksu discloses obtaining from the media file subsample descriptive metadata describing the subsample information, the subsample descriptive metadata comprising for each subsample a subsample description ( see Paragraph 0435 for the media file/coded bitstream having a sub-sample description box comprising a plurality of sub-sample entry types ), wherein each subsample description comprises an indication indicating whether the subsample description comprises a reference to at least one subsample’s property ( see Paragraph 0435 for extending a sub-sample information box to indicate the sub-sample entry index by indicating the order of presence of a sub-sample entry in the related sub-sample description box ). Aksu also discloses obtaining the property describing the subsample from the subsample’s property of the subsample description ( see Figure 2B and Paragraphs 0433-0435 for obtaining the coded bitstream and obtaining and signaling what type of packaging is used ). Referring to claim 17, see the rejection of claim 12 and further note Figure 2B for the device that obtains the coded bitstream.
