Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . DETAILED ACTION This office action is in response to communication filed 3/10/26. Response to Amendment The examiner acknowledges the amendment of claims 1,4, and 9. Response to Arguments Regarding applicant’s argument regarding the reference of Liu, it is the examiner’s position that the reference of Liu teaches identify that a first external device is physically connected to the electronic device through the connection unit (paragraph 024). Liu teaches obtaining information from the connector and determining configuration parameter for allowing the electronic device to control the external device (paragraph 017,025-026,041). In response to applicant’s argument that that the information about the signal type communication of Liu is merely information about the external device itself, rather than environment information about a connection state, it is the examiner’s position that the configuration parameter information is considered as information relating to the connection state that allows the external device to be controlled by the electronic device (paragraph 017,025-026,041). 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. Claim(s) 1,5,7,11-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al. US Patent Application Publication 20170300343 in view of Cantero Clares US Patent Application Publication 20250037419. Regarding claim 1, Liu teaches an electronic device, comprising: a connection unit (paragraph 017,019); and a processor configured to: identify that a first external device is physically connected to the electronic device through the connection unit (paragraph 024), identify connection information about the first external device, the identified connection information including device information about the first external device, information from the first external device, and environment information about a connection state of the first external device (data indicative of the connector element, paragraph 024-025), determine whether the first external device is a device controllable by the electronic device based on the identified connection information about the first external device for recognizing a plurality of external devices (configuration parameter indicates tasks or capability associated with the connected device, paragraph 017,025-026,041), identify at least one control scheme of the first external device in response to determining that the first external device is a device controllable by the electronic device (paragraph 028,041), and determine a control scheme of the identified at least one control scheme as a priority control scheme for controlling the first external device (control is determined based the detected configuration parameters, paragraph 07,017,041). Liu is silent on teaching at least one machine learning model and the connection information include image information from the first external device. Cantero Clares in an analogous art teaches receiving image information from the first external device and teaches the use of a machine learning model for recognizing the external device (fig.4, paragraph 045). It would have been obvious to one of ordinary skill in the art at the time of the invention to modify the system of Liu as disclosed by Cantero Clares because such modification represents an improvement over the system of Liu by providing additional external device recognition means for efficiently and reliably recognizing the connected external device and provide for the configuring of the interface between the host and the external connected device. Regarding claim 5, Liu teaches the processor is configured to, in case that it is identified that the first external device connected to the electronic device powers on: identify that the first external device is connected to the electronic device through the connection unit (paragraph 020,024). Regarding claim 7, Liu teaches the processor is configured to: display a user interface for determining the priority control scheme of the first external device in response to identifying the at least one control scheme of the first external device, and the user interface includes at least one object indicating the identified at least one control scheme, respectively (paragraph 059). Regarding claim 11-12, Liu is silent on teaching at least one machine learning model for recognizing the plurality of external devices includes at least one of a first machine learning model trained by using device information about a plurality of external devices, a second machine learning model trained by using image information about the plurality of external devices, or a third machine learning model trained by using data about devices failing to connect among the plurality of external devices. Cantero Clares in an analogous art teaches receiving image information from the first external device and teaches the use of a machine learning model for recognizing the external devices (fig.4, paragraph 045). Cantero Clares teaches a first machine learning model trained by using device information about a plurality of external devices (paragraph 040). Cantero Clares also teaches the machine learning model is received from a server device (paragraph 042). It would have been obvious to one of ordinary skill in the art at the time of the invention to modify the system of Liu as disclosed by Cantero Clares because such modification represents an improvement over the system of Liu by providing additional external device recognition means for efficiently and reliably recognizing the connected external device and provide for the configuring of the interface between the host and the external connected device. Regarding claim 13, Liu teaches the connection unit includes a high-definition multimedia interface (HDMI) connection unit (paragraph 05). Claim(s) 2-3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al. US Patent Application Publication 20170300343 in view of Cantero Clares US Patent Application Publication 20250037419 and further in view of Zhang US Patent Application Publication 20170366620.. Regarding claim 2, Liu is silent on teaching transmitting, to a server device, network information through the communication unit, and receive, from the server device, the identified connection information about the first external device, wherein the network information includes information about another device connected to a same network as the electronic device.
