Regarding applicant (Remark’s page 7-8) making statement that “During the interview, the Examiner agreed that the proposed amendments appeared to overcome the current rejections under 35 U.S.C. § 103. In particular, the cited references fail to teach or suggest at least "identify[ing]...a subset of network packets corresponding to a region of a video frame ... [that is] selected based at least on state data of an application that generated the video frame," as recited in amended independent claim 1 and similarly in amended independent claim 17.”
The examiner respectfully points out that as per the interview summary of interview conducted on 11 February 2026, it was mentioned in the interview summary that, general discussion was done related to proposed amendment in relation previously cited arts. However, no agreement was reached.
As per the rejection below, Gu does teach the amended feature of, “the region of the video frame selected based at least on state data of an application that generated the video frame” as disclosed in Gu, Col. 1, line 24 discloses, application such as video conferencing. Col. 2, line 60-62, business meetings via video conferencing (i.e. application running video conferencing on different user terminal during video conference. Col. 10, line 65-67, col. 11, line 1, the central section is fixed it does not change from frame to frame but in different example, central section may adjust overtime according to user input, i.e. based on user input while video conference changes the central section. Therefore region of the video frame is selected based on state data (i.e. user input) of the video conference application that generated the video frame of video conference.

Also, the edge data network 2000 may encode the extra FoV image 215 to generate a first extra FoV frame, i.e. Fov = user field of view or user has selected the view the area of frame. Par. edge data network 2000 may encode the user FoV image 210 by using a relatively high-image quality parameter (e.g., a high bit rate) and a high frame rate to generate a user FoV frame, and generate user FoV frame packets 220 including information about the user FoV frame. Par. 0088, encode the user FoV image 210 by using a relatively high-image quality parameter (e.g., a high bit rate) and a high frame rate to generate a user FoV frame, and generate user FoV frame packets 220 including information about the user FoV frame Par. 0106, appropriately allocate resources for the user FoV image and the extra FoV image according to an available bandwidth and a required latency given by a VR application, the edge data network 2000 may identify a transmission parameter, such as an FEC code rate or an FEC block size, and an encoding parameter related to image quality of each area (e.g., a frame data size), ), i.e. allocate higher amount bandwidth resources as fov image portion and associated FEC as they are sent in higher resolution quality, here higher amount of bandwidth assigned of total bandwidth reads on higher percentage of total bandwidth); and
allocate a second percentage of bandwidth for the encoded video stream to one or more second error correction packets for a packet sequence that carries regions of the video frame other than the selected region (Par. 0083The edge data network 2000 may encode the user FoV image 210 to generate a first user FoV frame.
