Detailed Action
This Office Action is made in reply to Application 18/988,227 filed 19 December 2024. As originally filed, Claims 1 – 20 are presented for examination.
Specification
The use of the term AIRPLAYTM, which is a trade name or a mark used in commerce, has been noted in this application. The term should be accompanied by the generic terminology; furthermore the term should be capitalized wherever it appears or, where appropriate, include a proper symbol indicating use in commerce such as ™, SM , or ® following the term.
Although the use of trade names and marks used in commerce (i.e., trademarks, service marks, certification marks, and collective marks) are permissible in patent applications, the proprietary nature of the marks should be respected and every effort made to prevent their use in any manner which might adversely affect their validity as commercial marks.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 7 – 19 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 7 contains the trademark/trade name “airplay” in line 6. Claim 11 contains the trademark/trade name “airplay” in lines 4 - 5. Claim 12 contains the trademark/trade name “airplay” in lines 3 and 5. Where a trademark or trade name is used in a claim as a limitation to identify or describe a particular material or product, the claim does not comply with the requirements of 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph. See Ex parte Simpson, 218 USPQ 1020 (Bd. App. 1982). The claim scope is uncertain since the trademark or trade name cannot be used properly to identify any particular material or product. A trademark or trade name is used to identify a source of goods, and not the goods themselves. Thus, a trademark or trade name does not identify or describe the goods associated with the trademark or trade name. In the present case, the trademark/trade name is used to identify/describe a content casting protocol/application and, accordingly, the identification/description is indefinite.
Allowable Subject Matter
Claims 10 and 17 – 19 are objected to as being dependent upon a rejected base claim, but would be allowable if all other rejections were overcome and the claims are rewritten in independent form including all of the limitations of the base claim and any intervening claims.
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.

But Murray does not explicitly disclose in response to the network status indicating that the network is disconnected, controlling the Wi-Fi module to enable network connection and to connect to a target network.
Yoden from a similar endeavor in response to the network status indicating that the network is disconnected, controlling the Wi-Fi module to enable network connection and to connect to a target network (Yoden: [0227], where if a media playback device has been turned off or disconnected from LAN 2, It can be turned on again and/or connected to LAN 2 again).
User equipment can cast media content to a media playback device over a local area network (LAN) where a local media content item stored on the cast device can be cast or the device may cast an online media content item stored on a remote server to the media playback device, (Yoden: [0005]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Murray in view of Yoden such that if a media playback device has been turned off or disconnected from a LAN, it can be turned on again or connect to the LAN again, (Yoden: [0227]). This addresses improvement, enhancement, or argumentation of wireless communication services with greater flexibility and efficiency, (Yoden: [0004]).
Claim(s) 2 – 3 and 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Murray in view of Yoden as applied to claims 1 and 5 above, and further in view of Baron et al., US Pub. 2018/0213478 A1 (hereinafter Baron).
Regarding Claim 2, the combined teaching of Murray and Yoden discloses display apparatus according to claim 1, wherein the processor is further configured to execute the computer instructions to cause the display apparatus to perform:
after controlling the WiFi module to enable the network connection and connecting to the target network, and before obtaining the casting data sent from the casting data source device via the target network and controlling the display to display the casting data on the interface for the casting channel, controlling the display to display a first prompt indicating that the network connection is being enabled and the network being connected (Yoden: [0141], where an acknowledgement message is issued indicating a positive reply for acceptance of streaming from the cast device; [0172], where notification messages can indicate the changing status of selected media playback devices from “available” to “occupied”);
determining, within a preset time, whether the network connection is successful (Yoden: [0221], where if the connection between the cast device and the display device is lost or accidentally stopped for some reason, the cast may be resumed upon discovering the playback device within a predetermined time period after the accidental termination);
in response to that the network connection fails, controlling the display to display a network setting interface (Yoden: [0222], where it is determined if the WLAN communication is kept established or is determined to be lost). But the combined teaching of Murray and Yoden fail to explicitly disclose wherein the network setting interface comprises a network switch control and identifiers of a plurality of available networks; receiving a selection input on a target network identifier from a user on the network setting interface; and in response to the selection input, attempting to connect to the target network indicated by the target network identifier.
Baron from a similar endeavor teaches wherein the network setting interface comprises a network switch control and identifiers of a plurality of available networks; receiving a selection input on a target network identifier from a user on the network setting interface (Baron: Fig. 2A and [0042], where before a device is successfully paired with a network receiver, an available networks pane 222 is populated listing nearby Wi-Fi networks, for example, Tom’s Home 208, BananStand 218 and Mike’s Home 220; Fig. 2A and [0045], where a user may select Tom” Home network 208 from the listed available networks); and

Because of its broad transmission range, faster connection, and larger bandwidth capabilities, Wi-Fi is optimal for operating full-scale networks that transfer and receive large amounts of data, (Baron: [0002]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combined teaching of Murray and Yoden in view of Baron such that when connecting devices for casting in a local network, the user is able to select from a list of available nearby networks, (Baron: [0042]). This automatically triggering of connections to the network receivers via WiFi signals helps to optimize the user experience by automating tedious and inconvenient processes, (Baron: [0032]).
Regarding Claim 3, the combined teaching of Murray and Yoden discloses display apparatus according to claim 1. The combined teaching of Murray and Yoden fails to explicitly disclose, wherein the processor is further configured to execute the computer instructions to cause the display apparatus to perform: after checking the network status of the Wi-Fi module and the casting switch status and before controlling the Wi-Fi module to enable the network connection and connecting to the target network, in response to the network status indicating that the network is disconnected, controlling the display to display a network setting interface, wherein the network setting interface comprises a network switch control and identifiers of a plurality of available networks.
Baron from a similar endeavor teach after checking the network status of the Wi-Fi module and the casting switch status and before controlling the Wi-Fi module to enable the network connection and connecting to the target network, in response to the network status indicating that the network is disconnected, controlling the display to display a network setting interface, wherein the network setting interface comprises a network switch control and identifiers of a plurality of available networks (Baron: Fig. 2A and [0042], where before a device is successfully paired with a network receiver, an available networks pane 222 is populated listing nearby Wi-Fi networks, for example, Tom’s Home 208, BananStand 218 and Mike’s Home 220; Fig. 2A and [0045], where a user may select Tom” Home network 208 from the listed available networks);
obtaining a first input for enabling the network connection on the network switch control in the network setting interface from a user (Baron: [0045], where a user may select Tom” Home network 208 from the listed available networks);
in response to the first input, controlling the WiFi module to enable the network connection and connecting to the target network (Baron: Fig. 2A and [0045], where upon selecting Tom’s Home network 208, the device 202 may exchange data with the network receiver and the network receiver may initiate a Bluetooth pairing step; [0046], where data is exchanged to determine if the device and the network are compatible and if so, the network receiver may transmit a Bluetooth pairing request to the device; Fig. 2C, [0047], where once the device accepts the BT pairing request, then the device may pair with the network receiver according to the Bluetooth pairing protocol).
Because of its broad transmission range, faster connection, and larger bandwidth capabilities, Wi-Fi is optimal for operating full-scale networks that transfer and receive large amounts of data, (Baron: [0002]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combined teaching of Murray and Yoden in view of Baron such that when connecting devices for casting in a local network, the user is able to select from a list of available nearby networks, (Baron: [0042]). This automatically triggering of connections to the network receivers via WiFi signals helps to optimize the user experience by automating tedious and inconvenient processes, (Baron: [0032]).
Regarding Claim 6, the combined teaching of Murray and Yoden discloses display apparatus according to claim 5. But the combined teaching of Murray and Yoden fails to explicitly disclose, wherein the casting resource comprises a casting key, and the processor is further configured to execute the computer instructions to cause the display apparatus to perform: while obtaining the casting data sent from the casting data source device via the target network and controlling the display to display the casting data on the interface for the casting channel, decrypting the casting data sent from the casting data source device using an updated casting key, and controlling the display to display decrypted casting data.
Baron from a similar endeavor teaches wherein the casting resource comprises a casting key (Baron: Fig. 1B and [0037], where the information exchanged between devices before pairing could include a link key), and the processor is further configured to execute the computer instructions to cause the display apparatus to perform:
while obtaining the casting data sent from the casting data source device via the target network and controlling the display to display the casting data on the interface for the casting channel, decrypting the casting data sent from the casting data source device using an updated casting key, and controlling the display to display decrypted casting data (Baron: [0037], where data exchanged while pairing two devices could include a shared secret known as a link key defined as a cryptographically unique identifier that is shared only between the two devices).
Because of its broad transmission range, faster connection, and larger bandwidth capabilities, Wi-Fi is optimal for operating full-scale networks that transfer and receive large amounts of data, (Baron: [0002]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combined teaching of Murray and Yoden in view of Baron such that when connecting devices for casting in a local network, the user is able to select from a list of available nearby networks, (Baron: [0042]). This automatically triggering of connections to the network receivers via WiFi signals helps to optimize the user experience by automating tedious and inconvenient processes, (Baron: [0032]).

based on determining that the display is showing the casting information page, controlling the display to switch to a specified page (Murray: [0051], where the home button functions as a quick cast button to enable immediate play of media content provided by a specific Internet content channel). But the combination of Murray and Yoden fails to explicitly disclose in response to the return instruction, determining whether the display is showing a casting information page which meets a requirement of an airplay protocol.
Hierro from a similar endeavor in combination with Murray and Yoden teaches in response to the return instruction, determining whether the display is showing a casting information page which meets a requirement of an airplay protocol (Hierro: [0204], where many mobile phones stream content wirelessly, for instance, to an AirPlay enable receiver, as the Apple AirPlay protocol allows streaming; Murray: [0034], where the display device includes a regular TV display that is coupled to a TV box, e.g. Google TV or Apple TV products).
If a specific player request by a DRM scheme when streaming multimedia content is not the native player of the user device, the performance of the digital content reproduction may be reduced, (Hierro: [0020]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Murray and Yoden in view of Hierro such that media can be streamed on a user device via Apple AirPlay protocol, (Hierro: [0204]).

decrypt the second encrypted file with the second decryption key to obtain the service credential (Hierro: [0050], where for decrypting the digital content, keys from the DRM server are requested including key identification used by the DRM server to derive the key or keys for decryption; [0201], where credentials are generated in association with DRM).
Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Murray in view of Yoden and Hierro as applied to claim 8 above, and further in view of Gao, US Pub. 2023/0367441 A1 (hereinafter Gao).
Regarding Claim 9, the combined teaching of Murray, Yoden and Hierro discloses display apparatus according to claim 8. wherein the processor is further configured to execute the computer instructions to cause the display apparatus to perform:
based on that the data source object that is active before the display apparatus displaying the casting information page is a signal source supported by the display apparatus, controlling the display to switch to a desktop of an operating system of the display apparatus (Murray: [0055], where an operating system includes procedures for handling various basic system services; [0051], where a home button controls the display device to display a home screen). The combined teaching of Murray, Yoden and Hierro fails to explicitly teach, based on that the data source object that is active before the display apparatus displaying the casting information page is an application installed in an application layer of the operating system of the display apparatus, controlling the display to switch to a homepage of the application.
Gao from a similar endeavor teaches based on that the data source object that is active before the display apparatus displaying the casting information page is an application installed in an application layer of the operating system of the display apparatus, controlling the display to switch to a homepage of the application (Gao: [0239], where a first application interface is a native application interface and a request may induce switching of the application interface. A pop-up application interface may be an application interface at a lower layer of the current application interface, where, for example, the current application interface is a video application home page).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combined teaching of Murray, Yoden and Hierro in view of Gao such that the casting function disclosed by Murray, Yoden and Hierro could occur as a multi-window projection scenario in the layered architecture disclosed by Gao, (Gao: [0118]). Goa discloses an Android system with layered architecture including an application layer, an application framework layer, a system library, an Android runtime, and a kernel layer for the multi-window projection scenario, (Gao: Fig. 4 and [0119]). This allows for when performing a multi-window projection scenario, a projection interface can be projected in an adapted state and an adapted size, thereby improving user experience of projection, (Gao: [0006]).
Claim(s) 11 - 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Murray in view of Yoden and Hierro as applied to claim 7 above, and further in view of Perold et al., US Pub. 2015/0334562 A1 (hereinafter Perold).
Regarding Claim 11, the combined teaching of Murray, Yoden and Hierro discloses display apparatus according to claim 7. But the combined teaching of Murray, Yoden and Hierro fail to explicitly disclose, wherein the processor is further configured to execute the computer instructions to cause the display apparatus to perform: based on determining that the display is showing the casting information page, invoking an airplay Software Development Kit (SDK) in the display apparatus to broadcast the return instruction to an airplay application, to allow the airplay application to control the display to switch to the specified page in response to the return instruction.
Perold from a similar endeavor in combination with Murray, Yoden and Hierro teaches based on determining that the display is showing the casting information page, invoking an airplay Software Development Kit (SDK) in the display apparatus to broadcast the return instruction to an airplay application, to allow the airplay application to control the display to switch to the specified page in response to the return instruction (Perold: [0073], where suitable mobile application development environments are available from several sources including Airplay SDK; Hierro: [0204], where many mobile phones stream content wirelessly, for instance, to an AirPlay enable receiver, as the Apple AirPlay protocol allows streaming; Murray: [0034], where the display device includes a regular TV display that is coupled to a TV box, e.g. Google TV or Apple TV products; Murray: [0051], where the home button functions as a quick cast button to enable immediate play of media content provided by a specific Internet content channel).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Murray, Yoden, and Hierro in view of Perold such that an Airplay SDK can be used, (Perold: [0073]). This invention allows resource access to be programmatically provisioned in a way that was either not possible or practical in the prior art, enabling the asset or resource to be provisioned to one or multi-users, (Perold: [0042]).
Regarding Claim 12, the combined teaching of Murray, Yoden, Hierro and Perold discloses display apparatus according to claim 11, wherein the processor is further configured to execute the computer instructions to cause the display apparatus to perform:
forwarding the return instruction to a startup service by invoking the airplay SDK; and
broadcasting the return instruction by invoking the startup service, to send the return instruction to the airplay application (Perold: [0073], where suitable mobile application development environments are available from several sources including Airplay SDK; Hierro: [0204], where many mobile phones stream content wirelessly, for instance, to an AirPlay enable receiver, as the Apple AirPlay protocol allows streaming).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Kiley et al., US Pub. 2019/0069015 A1 teach determining if the user access gateway integration is available and if so a “cast” button on the device is pressed and the user is prompted to connect to vCast, which connects the device to the controller over the network. If hotel does not have user access gateway integration, a pairing code is displayed on the Chromecast device and the guest can enter the pairing code and a connection is created, (Fig. 3 and [0018]-[0019]).
Rombakh et al., US Pub. 2018/0241609 A1 teach that virtual cast devices can represent cast devices. For example, using Chromecast or Apple TV, a virtual cast device can appear as if it were a Chromecast or Apple TV, ([0028]). Media Status messages can be sent to cast sender in response to a request, ([0034]).
Hwang et al., US Pub. 2021/0303253 A1 teach using a screen sharing service, e.g. Miracast, screen mirroring, airplay, wireless display, etc., to control an electronic device by a user input back channel, ([0003], [0007] and [0034]). A communicator can be controlled to transmit UI data to an external device through a screen sharing channel, ([0042]). During a screen sharing session, the electronic device may change a channel being broadcast by user dragging the screen of the external device to the left or to the right, ([0110]).
Nakagawa, US Pub. 2018/0268869 A1 teach establishing a Wi-Fi Display connection and then the source and sink devices can share parameter information needed to establish a network connection therebetween, ([0042] – [0044]).
Yanazume et al., US Pub. 2017/0110083 A1 teach part-selecting via images in a case where the display device is a multi-function model. For example, a display part 1330-6 for providing an instruction to execute a function of switching input channels to a SCREEN MIRRORING, (Fig. 12 and [0124]-[0125]).
