Claim Rejections - 35 USC § 103 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. Claims 16-35 are rejected under 35 U.S.C 103 as being unpatentable over “3GPP TSG-SA WG6 Meeting #37-e, E-meeting, 8 May 2020, S6-200764, Convida Wireless LCC, Solution to the Key Issue of Message Segmentation and Reassembly, 3GPP TR 23.700 v0.5.0” (hereinafter as “S6-200764”) in view of Casaccia (US 2003/0035440) Regarding Claim 16, “S6-200764” teaches a method performed by a source node in a wireless communication system, the method comprising: receiving a message related to an application (“S6-200764”, Fig 6.X.1.2-1: MT MSGin5G Message Segmentation and Reassembly, step 1, an Application Server sends a message to a MSGin5G Server that targets an Application Client on a UE); identifying whether a size of the message related to the application exceeds a maximum allowed packet size (“S6-200764”, Fig 6.X.1.2-1: MT MSGin5G Message Segmentation and Reassembly, in step 2 the MSGin5G Server compares the size of the received message to the maximum allowed packet size of the access network transport of the targeted UE and detects that the size exceeds the limit); segmenting the message related to the application into one or more segmented messages based on the maximum allowed packet size (“S6-200764”, Fig 6.X.1.2-1: MT MSGin5G Message Segmentation and Reassembly, in step 2 if the size of the received message exceeds the maximum allowed packet size, then the MSGin5G Sever segments the received message into a set of segmented messages such that each segmented message can fit within an individual access network transport packet); transmitting, to a destination node, the one or more segmented messages (“S6-200764”, Fig 6.X.1.2-1: MT MSGin5G Message Segmentation and Reassembly, in step 3 the MSGin5G Server sends each segmented message to the targeted UE within an individual access network transport packet); PNG media_image1.png 622 848 media_image1.png Greyscale “S6-200764” does not explicitly teach the below limitations: receiving a confirmation message associated with the message related to the application, wherein result information included in the confirmation message is determined based on the one or more segmented messages. However Casaccia teaches the below limitations: receiving a confirmation message associated with the message related to the application, wherein result information included in the confirmation message is determined based on the one or more segmented messages (Casaccia, Fig 9B, paragraph 83, the receiver receives the message from time t2 to t3, a NAK message is sent by the receiver from t3 to t4, the NAK message identifies the missing segment of the transmitted message, the NAK message is interpreted as being the confirmation message).
