Regarding Claim 11, it has been rejected for the same reasons as claim 3. Regarding Claim 12, it has been rejected for the same reasons as claim 4. Regarding Claim 13, it has been rejected for the same reasons as claim 5. Regarding Claim 14, it has been rejected for the same reasons as claim 6. Regarding Claim 15, it has been rejected for the same reasons as claim 7. Regarding Claim 16, it has been rejected for the same reasons as claim 8. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 17, 20-22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Fang et al. Pub. No. US 20230216990 A1 in view of Official Notice Regarding Claim 17, it has been rejected for the same reasons as claim 1 and further teaches a terminal device, comprising: a processor (Fig. 2 Unit 110, processor; and a memory coupled to the processor (Fig. 2 Unit 120 and 121 where memory coupled to the processor), wherein the memory is configured to stores a code instructions that, when executed by the processor is configured to execute the code instruction (Para 159, The internal memory 121 may be configured to store one or more computer programs, and the one or more computer programs include instructions. The processor 110 may run the instructions stored in the internal memory 121, so that the electronic device 100 is enabled to perform the data sharing method provided in some embodiments of this application); and wherein the first call transfer indication message causes the main terminal device to update a displayed window from a window indicating that the current call is answered on the terminal device to a window indicating that the current call is answered on the main terminal device (Para 240, After the mobile phone switches the video call to the smart television 102, the mobile phone returns to the user interface before the video call is generated. For example, the mobile phone displays a home screen before receiving a video call request. As shown in FIG. 4(d), after the mobile phone switches the video call to the smart television 102, the mobile phone returns to the home screen. In some embodiments, the graphical user interface may include a first notification message 214. The first notification message 214 may display text information, for example, “The video call is being performed on the living room television”, to prompt the user that the video call is being performed on the living room television. The graphical user interface may further include a control 215. If the mobile phone detects an operation performed on the control, the mobile phone may send a third switching message to the smart television 102. In response to the third switching message, the mobile phone may continue the video call and display data collected by the camera of the other party, and the smart television 102 may display an interface displayed before a moment at which the mobile phone switches the video call to the smart television 102. In some other embodiments, if the mobile phone displays an interface of another application (such as gallery or reading) or an interface of a video call application before receiving the video call request, after the mobile phone switches the video call to the smart television 102, the mobile phone may display a corresponding interface before the switching. For a video call initiator, an interface displayed by the video call initiator before the video call request is initiated may include information about a called contact, a chat window with the called contact, or the like. After the mobile phone switches the video call to the smart television, the mobile phone may display a response interface before the switching i.e., the first call transfer indication message causes the main terminal device to update a displayed window from a window indicating that the current call is answered on the terminal device to a window indicating that the current call is answered on the main terminal device). Fang does not specifically teach wherein the main terminal device is a device that receives calls from a telecommunications network operator via a subscriber identity module. However, examiner would like to take official notice as it is well known in the art of communication that mobile device 100 of Fang inherently has a subscriber identity module that receives the call from a telecommunication network operator. Therefore, it would have been obvious for one having ordinary skill in the art before the effective filing date of the claimed invention to come to conclusion with the method of Fang so user can fully use capabilities of each intelligent device and can obtain better user experience during the video call. Regarding Claim 20, it has been rejected for the same reasons as claim 2. Regarding Claim 21, it has been rejected for the same reasons as claim 3. Regarding Claim 22, Fang teaches wherein sending the first call transfer indication message to the main terminal device in response to the user operation on the call transfer key comprises: displaying, by the terminal device, a candidate device list in response to the user operation on the call transfer key, wherein the candidate device list comprises a device that is located in the same local area network and logs in with the same user account as the terminal device; and sending, by the terminal device, the first call transfer indication message to the main terminal device in response to a user operation of choosing the main terminal device from the candidate device list (Para 247 and Fig. 7b). Response to Arguments Applicant's arguments filed 4/08/2026 have been fully considered but they are not persuasive. Applicant is arguing with regards to claim 1, that the first window is displayed in response to the call being in an answer state and suggest that Fang does not teach the current limitation. However, examiner disagrees and applicant would like to bring it to the attention of the applicant that during patent examination, claims must be given the broadest reasonable interpretation (See MPEP 2111). Having said that, Fang teaches from Para 193, The phone manager is configured to provide a communications function of the electronic device 100, for example, management of a call status (including answering, declining, or the like) i.e., current call status is displayed and then Para 224 and Fig. 3(b), the graphical user interface may include a status bar, a navigation bar, a hang-up control 201, a voice switching control 202, an answering control 206, first information 203, second information 204, and third information 205 i.e., by the first auxiliary terminal device and then disclose from Para 215 and Fig. 3(a) to FIG. 3(d) show an example of graphical user interfaces during multi-device interaction according to an embodiment of this application. FIG. 3(a) and FIG. 3(b) respectively show user interfaces when a user makes and answers a video call by using a video call application. As shown in FIG. 3(a), the user interface may include a status bar 21, a navigation bar 22, a hang-up control 201, a voice switching control 202, first information 203, second information 204, and third information 205 i.e., a first window is displaying. Fang teaches from Para 225, The answering control 206 is configured to answer the video call. The mobile phone may detect a touch operation performed on the answering control 206 (for example, a tap operation performed on the answering control 206). In response to the operation, the mobile phone may answer the video call, and start to display data collected by a camera of the other party. It is noted that applicant is claiming that the current call being in the answering state i.e., in response to a current call being in an answer state. It is noted that applicant is claiming that the current call “being” in an answer state which mean that “to be” in the answering state and therefore, Fig. 3b reads on applicant claimed invention and for those reasons, rejection is maintained. Applicant is further arguing that since claim 9 is rejected based on combination of claim 1 and 8 and the current feature is not present in claim 1 and 8, therefore, applicant is requesting withdrawal of the rejection. However, examiner disagree. As explained above Fang clearly disclose all limitation of claim 1. Therefore, for at least the above reasons applicant argument is not persuasive and the rejection is maintained. Applicant is further arguing that amended independent claim 17 require the first call transfer indication message causes the main terminal device to update a displayed window from a window indicating that the current call is answered on the terminal device to a window indicating that the current call is answered on the main terminal device and suggest that Fig. 4(b) that there is no window on the television displaying that the call is being answered on the mobile phone. The television has no awareness of or UI indication of the mobile phone's call state prior to receiving the switching message. However, examiner disagree. First of according to claim language it suggests that the main terminal device to update a displayed window from a window indicating that the current call is answered on the terminal device to a window indicating that the current call is answered on the main terminal device. Fang clearly teaches that limitation. Fang teaches from Para 240, After the mobile phone switches the video call to the smart television 102, the mobile phone returns to the user interface before the video call is generated. For example, the mobile phone displays a home screen before receiving a video call request. As shown in FIG. 4(d), after the mobile phone switches the video call to the smart television 102, the mobile phone returns to the home screen. In some embodiments, the graphical user interface may include a first notification message 214. The first notification message 214 may display text information, for example, “The video call is being performed on the living room television”, to prompt the user that the video call is being performed on the living room television. The graphical user interface may further include a control 215. If the mobile phone detects an operation performed on the control, the mobile phone may send a third switching message to the smart television 102. In response to the third switching message, the mobile phone may continue the video call and display data collected by the camera of the other party, and the smart television 102 may display an interface displayed before a moment at which the mobile phone switches the video call to the smart television 102. In some other embodiments, if the mobile phone displays an interface of another application (such as gallery or reading) or an interface of a video call application before receiving the video call request, after the mobile phone switches the video call to the smart television 102, the mobile phone may display a corresponding interface before the switching. For a video call initiator, an interface displayed by the video call initiator before the video call request is initiated may include information about a called contact, a chat window with the called contact, or the like. After the mobile phone switches the video call to the smart television, the mobile phone may display a response interface before the switching i.e., the first call transfer indication message causes the main terminal device to update a displayed window from a window indicating that the current call is answered on the terminal device to a window indicating that the current call is answered on the main terminal device For at least the above reasons applicant argument is not persuasive and the rejection is maintained.
