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. Claim(s) 4, 7-8, 10-16, 18, 20, 22-23, 27-28 and 32-36 is/are rejected under 35 U.S.C. 103 as being unpatentable over Asterjadhi [US 2016/0219522] in view of Kneckt [US 2020/0045634 which claims priority of provisional application 62/714416]. As claims 4, 20, 22 and 32-34, Asterjadhi [US 2016/0219522] discloses a method for wireless communications comprising, at a station [Fig 1, Ref 114] receiving, from the access point (AP) [Fig 1, Ref 104], a management frame announcing TWT schedule information of the broadcast TWT by containing a broadcast TWT element in the management frame [Fig 8, Ref 805 discloses Ref 114 receives announcing a Target Wake Time (TWT) schedule information of the broadcast TWT by containing a broadcast TWT element in the management frame, Fig 2, Par. 0054-0055, 0075]; receiving, from the AP, a trigger frame allocating a resource unit (RU) within the during a TWT service period indicated by the broadcast TWT element contained in the management frame [Fig 8, Ref 815 discloses Ref 114 receives a trigger frame during TWT SP indicated in the broadcast TWT element contained in the management frame]; and transmitting the a frame during a the TWT service period in response to the trigger frame [Fig 8, Ref 820, 825 discloses Ref 114 transmits a frame during a the TWT service period in response to the triggered frame], wherein the broadcast TWT element includes a broadcast TWT Recommendation field configured to set a value to 4, the value 4 indicating that the station prioritizes a transmission of latency sensitive traffic during the TWT service period in priority defined a type of traffic specified during the setup of the TWT service period [Fig 2, Ref TWT flow identifier “a broadcast TWT Recommendation field” set to a value 4 which indicates that the station prioritizes a transmission of latency sensitive traffic such as video as defined by the one or more traffic identifiers during the TWT service period, Par. 0068]. However, Asterjadhi [US 2016/0219522] fails to disclose requesting to an access point (AP) to become a member of broadcast Target Wake Time (TWT) the broadcast TWT element includes a broadcast TWT Recommendation field configured to set a value to 4 that is not a traffic identifier, the value 4 indicating that the station prioritizes a transmission of latency sensitive traffic as defined by the one or more traffic identifiers, during the TWT service period. In the same field of endeavor, Kneckt [US 2020/0045634] discloses requesting to an access point (AP) to become a member of broadcast Target Wake Time (TWT) [Par. 0037, 0042, 0055 discloses Sink joins the broadcast scheduler TWT of source], the broadcast TWT element includes a broadcast TWT Recommendation field configured to set a value to 4 that is not a traffic identifier, the value 4 indicating that the station prioritizes a transmission of latency sensitive traffic as defined by the one or more traffic identifiers, during the TWT service period.
