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 (i.e., changing from AIA to pre-AIA ) 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.
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.

Regarding claim 1. Xia teaches A method comprising:
receiving, by a computing device a plurality of indications from a plurality of user devices, (Fig. 30, BSRs from transmitter 1, 2, 3 of Non-AP shared STA) wherein the plurality of indications are associated with a plurality of packets to be sent by the plurality of user devices; ([0213] An optional collection of buffer status reports is performed 556. In this example the AP periodically broadcasts a BSRP frame 558 to inquire on buffer status of the non-AP STAs, with NAV (BSRP) 555 commencing. The non-AP STAs respond with a BSR frame 560, 562 and 564 to indicate their buffer status and packet information,)

The basic trigger frame indicates the assigned RU (or RUs) for each non-AP STA to transmit UL DATA sequences.) and
causing the first user device to send the first packet at the first time (see above [0215] via the first portion of the bandwidth of the channel ([0095] With the use of wide channels for data transmission, up to 160 MHz, the channel is expected to be interference frequency selective where some frequencies experience different interference levels than others, which affects expected achievable rate and degrades performance. To solve this problem 802.11ax introduced OFDMA where adjacent subcarriers are grouped into resource units (RUs).) and at least one second user device to send a second packet, of the plurality of packets, at the first time via a second portion of the bandwidth of the channel, wherein the second packet is associated with a second quality of service (QoS) priority.

Non-real-time applications such as file transfer, Email, and data backup can tolerate greater delay. Station 204B is supplied with voice and video data from data source 214B, which has a higher QoS priority QoS(B). Voice and video applications have the most rigorous delay and loss requirements.)
