Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Amendment
This action is in response to the application filed on December 11, 2025
Claims 1, 3-6, 8-11,13 and 14 are under examination.
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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, 3-6, 8-11,13 and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ngo et al. (USP 2008/0037540) in view of Duncan Ho (USP: 2009/0141670)

Response to Argument(s)
Applicant's argument(s) filed on December 11, 2025 have been fully considered but they are not persuasive. Therefore, the rejection is maintained.
In the remarks, at page 6 and 7 the Applicant argues in substance that:
Remark:
(A) “Ngo neither teaches nor suggests, in response to the type of the data being isochronous data, generating a MAC frame for transmission of the isochronous data, the MAC frame comprising a header consisting only of a frame control field. Rather, Ngo merely discloses extending the MAC header to accommodate various fields.....”
Response: In response, Examiner respectfully disagrees with applicant’s representative’s assertions. The Examiner has thoroughly reviewed Applicants' representative’s arguments but firmly believes that the cited references to reasonably and properly meet the claimed limitation. Applicant’s representative’s are reminded that the Examiner is entitled to give the broadest reasonable interpretation to the language of the claims. Examiner appreciates applicant’s representative’s explanation however, Ngo explicitly states that the Isochronous data is real-time data (like audio/video) sent with a guaranteed, constant flow and fixed time intervals between packets, ensuring timely delivery for multimedia applications where gaps or delays are unacceptable, even if it means sacrificing some data accuracy for timeliness, unlike asynchronous data (irregular) or synchronous data (rigid intervals). It uses a shared clock to keep transmission synchronized, crucial for streaming applications like video calls or broadcasts..... Example from Ngo (Paragraph 0031, 0065 The LRP supports multiple data rates, including directional modes, and is used to carry low-rate isochronous data such as audio, low-rate asynchronous data, MAC commands including the beacon frame, acknowledgements for HRP packets, antenna steering information, capabilities information, and higher layer control data for A/V devices. a payload data packet from the application layer; a MAC header of a fixed length; a MAC header extension of a variable length; a PHY header for synchronizing the behavior of the PHY layer; a first CRC segment for a cyclic redundancy checksum for checking transmission of the MAC header and the PHY header; and a second CRC segment for a cyclic redundancy checksum for checking transmission of the MAC header extension. The MAC header extension comprises a size indication of the MAC header extension for facilitating checking of the second CRC segment. The payload includes a separate CRC field for detecting transmission errors at the receiver...)
Therefore Ngo and Duncan Ho reference teaches the claim limitation as currently presented.
Examiner’s Note
Examiner is open for discussion if the applicant’s representative need further clarifications.
