It would have been obvious to a person skill in the art before the effectively filing date of the claimed invention to combine the teaching of Pang, Tian and Yoon because the teaching of Yoon would enable to provide real-time image previewing or capturing [ Yoon, paragraph 0158 ].
Response to Arguments
Applicant's arguments filed 08/11/2026 have been fully considered but they are not persuasive.
As per remarks, Applicants argued that (1) Pang’s instructions are directed solely to stop data transmission or screen transfer, none of the cited passages in Pang disclose instructions that actively cause the display device itself to terminate its display operation.
As to point (1), Examiner respectively disagrees because Pang discloses that the USB connector is unplugged, the SoC may transmit the stop screen transfer instruction to the large0format display device, causing the large-format display device to stop displaying media data packets [ i.e. broadly interpreted as cause the display device itself to terminate its display operation as argued [ paragraph 0063 ]. As such, the claimed language remains rejected as written, unpatentable over the cited prior art.
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
