`
`TECHNICAL FIELD
`
`[0002] The following description relates generally to providing ana graphical user interface and more
`particularly to providing an IM conversation counter and indicator for a tabbed instant messaging user
`interface having a tear-off element.
`
`BACKGROUND
`
`[0003] Online service providers facilitate access to information and services by providing interactive UIs
`(User Interfaces) that help users navigate to desired resources. UIs often take advantage of the graphics
`capabilities of a user's computer and eliminate the need to manually type text commands. Generally, a UI
`allows a user to execute particular commands or to link to certain locations by simply selectingsimply
`select screen objects such as icons, windows, and drop-down menus to execute particular commands or
`to link to certain locations. The design of a UI has a significant impact on a user's online experience. In
`particular, the icons, the windows, and the menus of a UI maymust be arranged to enable a user to
`locate preferred information and services quickly and easily. Conventionally, navigation among interfaces
`corresponding to separate communications sessions was accomplished through the selection if disparate
`icons appearing in an operating system task bar, where the icons appeared along with other icons that
`did not correspond to communications sessions.
`
`SUMMARY
`
`[0004] In one general aspect, a user interface on a displaythat enables user perception of
`informationstatus regarding a communications session that leveragesleverage an instant messaging
`platform may be rendered on a display. The user interface includes an instant messaging application
`user interface and one or more tear-off elements corresponding to ongoing instant messaging
`communications sessions. Each tear-off element is configured to enablethat enables perception and
`selection by a user of a correspondingof instant messages for an instant messaging communications
`session. Also, each tear-off element is configured to be independently visually separated from other
`elements of theuser, and a status indicator that provides a perceivable indication to the user of statistics
`regarding concurrent instant messaging application user interface and maintained as a separate entity on
`the instant messaging application user interfacesessions.
`
`[0005] Implementations may include one or more of the following features. For example, the instant
`messaging application user interface may include a general interface tear-off element that is configured
`to enable perception and selection of several of the tear-off elements collectively and to enable collective
`visual separation of the several tear-off elements from other elements of thealso include one or more
`instant messaging application user interface. The general interface tear-off element may be, for example,
`a tab or a button. The interface may be configured to enable reattachment to other elements of the
`general interface. For instance, a tear-off element may be configured to be reattached to an interface
`other than the interface from which the tear-off element was separated.
`sub-interfaces that represent distinct [0006]and concurrent instant messaging communications sessions.
`In one implementation, one or more tear-off elements may be dedicated to and enable perception and
`selection of a single corresponding instant messaging communications session. The dedicated tear-off
`elements may be independently visually separable from other elements of the instant messaging
`application user interface. The dedicated tear-off elements may include, for example, tabs or buttons.
`The user interface may also include a manual status control associated with a dedicated tear-off element.
`For instance, the manual status control may enable an indication of whether a message in the
`corresponding instant messaging communications session has been perceived by the user.the user
`interface includes a perceivable status indication that a new message is pending in at least one
`concurrent instant messaging session.

`
`

`

`[0007] In one implementation, one or more of the tear-off elements may be rendered visually as an
`integral part of the instant messaging application user interface. In another implementation, the display of
`the tear-off element persists when the element is visually separated from other elements of the instant
`messaging application user interface. In yet another implementation, the tear-off element may be
`configured to enable reattachment to other elements of the instant messaging application user interface.
`In another implementation, the user interface also includes a mechanism to determine the statistics. The
`statistics may include one or more of the following: a total number of concurrent instant messaging
`sessions; a number of instant messaging sessions with new messages; a number of new instant
`messaging sessions; and a number of new instant messages. The number of instant messaging
`sessions with new messages may further include a number of new instant messaging sessions with new
`messages and a number of old instant messaging sessions with new messages.
`
`[0008] The tear-off elements may be configured to be separately manipulable. In one implementation,
`one or more of the tear-off elements may be configured to be separately removable from the instant
`messaging application user interface, separately invokable, separately minimizable and/or separately
`movable.
`The statistics may be rendered in numerous positions on the display. For example, the statistics may be
`rendered in a title bar, in a tab header in an interface having persistent tabs, in an operating system tray,
`in a user interface toolbar, in a general interface that persists beyond active display of the user interface,
`or in a general interface actionable item that is arranged in a position on the display and that persists
`beyond active display of the user interface, where the general user interface actionable item enables
`activation of the user interface.
`
`[0009] In one implementation, more than one of the tear-off elements may be configured to be collectively
`visually separated from other elements of the instant messaging application user interface and
`maintained as a separate display elementthe user interface is a visual interface. In another
`implementation, a tear-off element may configured to be individually visually separated from other
`elements of the instant messaging application user interface and maintained as a separate display
`element. In yet another implementation, the instant messaging application user interface and tear-off
`elements may be configured to display limited information about one or more concurrent instant
`messaging sessions. For instance, the user interface may enable a more detailed display of one or more
`of the instant messaging sessions through selection of a corresponding tear-off elementis an audible
`interface.
`
`[0010] Aspects of the instant messagingIM conversation counter and indicator for a tabbed IM user
`interface having a tear-off element may be implemented by an apparatus and/or by a computer program
`stored on a computer readable medium. The computer readable medium may comprise a disc, a client
`device, a host device, and/or a propagated signal. In addition, aspects of the instant messagingIM
`conversation counter and indicator for a tabbed IM user interface having a tear-off element may be
`implemented in a client/host context or in a standalone or offline client device. The instant messagingIM
`conversation counter and indicator for a tabbed IM user interface having a tear-off element may be
`rendered in a client/host context and may be accessed or updated through a remote device in a
`client/host environment. The instant messagingIM conversation counter and indicator for a tabbed IM
`user interface having a tear-off element also may be rendered by the standalonestanalone/offline device
`and may be accessed or updated through a remote device in a non-client/host environment such as, for
`example, a LAN server serving an end user or a mainframe serving a terminal device.
`
`[0011] Other features and advantages will be apparent from the following description, including the
`drawings, and from the claims.

`
`DETAILED DESCRIPTION
`
`[0016] In general, one or more tear-off elements may be provided in an interface for instant messaging
`(IM) applications or other online applications. For example, tear-off elements may be provided to
`collectively form a tabbed IM user interface (UI), where each tear-off element represents a corresponding
`ongoing IM session. A user may tear-off one or more of the tear-off elements individually or collectively.
`Tear-off elements that have been torn off may be independently or collectively reattached to the user
`interface from which they were torn, or they may be reattached to a different user interface. In addition,
`once torn, the tear-off elements may be separately or collectively manipulated, moved, minimized,
`invoked, and activated.
`[0017] In the example of a tabbed IM UI, the tear-off elements may be presented as tabs positionedIn
`general, an IM conversation counter and indicator may be provided for a tabbed instant messaging (IM)
`user interface (UI), and the tabbed IM UI may have one or more IM interface tabs. Each interface tab is
`assigned to a pending IM session, and the tabs appear adjacent to one another to enable selection of
`and, among other things, help ease switching between IM sessions, and other operations. When several
`tear-off element tabs are concurrently shown, an. An active tab corresponds tois rendered for the IM
`session currently being viewed or manipulated by the user, and inactive tabs correspond toare rendered
`for the IM sessions which are not currently being viewed or manipulated by the user. A tear-off
`elementinterface tab typically includes an identifier, such as the screen name of an IM buddy, to identify
`the particular IM session to which the tabit is assigned. When displayed, the identifier for an IM session
`typically is configured such that a user is able to read or otherwise recognize the identifier without
`additional information. A tear-off element tab also may includeno matter how many other IM sessions are
`pending. An interface tab also includes a status indicator to indicate whether a new IM message is
`waiting to be viewed in the IM sessionfor that session. A conversation counter may be provided to inform
`the user of information relating to the concurrent IM sessions, such as the total number of concurrent IM
`sessions, the number of new IM sessions, and the number of ongoing IM sessions having a new IM
`message waiting to be viewed. A scroll bar is provided for scrolling to perceive tabs corresponding to that
`tear-off element tab.open IM sessions when the total number of concurrent IM sessions exceeds the
`maximum number of concurrent conversations that may be displayed simultaneously. The scroll bar
`allows a user to scroll up and down among the concurrent IM sessions, and may provide an indication
`that one or more of the IM sessions "hidden" by the scroll bar has a new IM message waiting to be
`viewed.
`
`In one implementation, an IM counter and indicator is provided on a tabbed IM UI to count the total
`number of concurrent IM sessions, the number of new IM sessions, and/or the number of new messages
`from ongoing IM sessions. A new IM session (i.e., a new conversation) may be flagged differently from
`an ongoing IM session with a new message. Thus, a user knows if and how many new IM sessions
`and/or new IM messages are present, even when viewing a different content area. Furthermore, when
`using the tabbed instant message (IM) user interface, new IM messages may or may not be forced into
`the foreground.
`
`An indicator is provided to the user to indicate whether the user has viewed a received IM message in an
`existing IM session. For example, an indicator such as a blinking interface tab or area on an interface tab
`may be provided for a received IM message that has not been viewed. When the user views the received
`IM, the indicator may change to a solid IM interface tab or area on an interface tab. The user will be able
`to know that a new, unviewed message has been received without having to close a window or leave a
`current IM session, and once viewed, the indicator changes without having to actually reply to the
`message itself. A different visual indication may be provided for a new IM session to distinguish the new

`

`

`session from a new message in an old session. The tabbed IM user interface may be rendered in
`response to user manipulation of a general IM user interface tab.
`
`[0018] A tear-off elementThe IM conversation counter and indicator for a tabbed IM user interface may be
`rendered by any type of hardware, software, device, computer, computer system, equipment,
`component, program, application, code, storage medium, or propagated signal. In one implementation,
`the tear-off element isIM conversation counter and indicator for a tabbed IM user interface may be
`rendered in a client/host context, and the tear-off elementIM conversation counter and indicator for a
`tabbed IM user interface may be accessed or updated through a remote device in a client/host
`environment. In another implementation, the tear-off element isIM conversation counter and indicator for
`a tabbed IM user interface may be implemented in a standalone or offline client context, where the tear-
`off element is. The IM conversation counter and indicator for a tabbed IM user interface may be rendered
`by the standalone/offline device and may be accessed or updated through a remote device in a non-
`client/host environment such as, for example, a LAN server serving an end user or a mainframe serving a
`terminal device.
`
`[0019] Typically, IMinstant messaging communications involveinvolves an instantaneous or nearly
`instantaneous communication between two users, where each user is able to perceiveprovided with
`online presence information regarding other selected users ("buddies"). The IM communications may be
`machine-to-machine communications that occur without intervention by, or communication through, an
`instant messaging server after a communication session is established or authentication is performed.
`Examples of IM communications include those provided by AIM (America Online Instant Messenger),
`AOL (America Online) Instant Messaging, Yahoo Messenger, MSN Messenger, and ICQ, among others.
`Although discussed below primarily with respect to IM applications, the tear-off element may be provided
`for other online applications such as chat, e-mail, and players for streaming media.
`
`[0020] For illustrative purposes, FIGS. 1 and 2 show an example of a communications system for
`implementing techniques for transferring electronic data. For brevity, several elements in the figures
`described below are represented as monolithic entities. However, as would be understood by one skilled
`in the art, these elements each may include numerous interconnected computers and components
`designed to perform a set of specified operations and/or may be dedicated to a particular geographical
`region.
`
`[0021] FIG. 1 illustrates a communications system 100 including a client system 105 communicating with
`a host system 110 through a communications link 115.
`
`[0022] The client device 120 typically includes a general-purpose computer 170 having an internal or
`external memorystorage 172 for storing data and programs such as an operating system 174 (e.g., DOS,
`Windows.TM., Windows 95.TM., Windows 98.TM., Windows 2000.TM., Windows Me.TM., Windows
`XP.TM., Windows NT.TM., OS/2, or Linux) and one or more application programs. Examples of
`application programs include authoring applications 176 (e.g., word processing programs, database
`programs, spreadsheet programs, or graphics programs) capable of generating documents or other
`electronic content; client applications 178 (e.g., America Online (AOL) client, CompuServe client, AOL
`Instant Messenger (AIM) client, interactive television (ITV)AOL TV client, Internet Service Provider (ISP)
`client, or instant messaging (IM) client) capable of communicating with other computer users, accessing
`various computer resources, and viewing, creating, or otherwise manipulating electronic content; and
`browser applications 180 (e.g., Netscape's Navigator or Microsoft's Internet Explorer) capable of
`rendering standard Internet content and other content formatted according to standard protocols such as
`the Hypertext Transfer Protocol (HTTP).
`
`[0023] OneThe general-purpose computer 170 also includes a central processing unit 182 (CPU) for
`executing instructions in response to commands from the client controller 125. In one implementation, the
`client controller 125 includes one or more of the application programs may be installed on the internal or
`external storage 172 of the general-purpose computer 170. Alternatively, inIn another implementation,
`the client controller 125 may accessincludes application programs externally stored in and/or performed
`by one or more device(s) external to the general-purpose computer 170.

`
`

`

`[0024] The general-purpose computer 170 also includes a central processing unit 182 (CPU) for
`executing instructions in response to commands from the client controller 125, andtypically will include a
`communication device 184 for sending and receiving data. One example of the communication device
`184 is a modem. Other examples include a transceiver, a set-top box, a communication card, a satellite
`dish, an antenna, aor another network adapter, or some other mechanism capable of transmitting and
`receiving data over the communications link 115 through a wired or wireless data pathway 150. The
`general-purpose computer 170 optionally includesalso may be a television ("TV") tuner 186 for receiving
`television programming in the form of broadcast, satellite, and/or cable TV signals. The TV tuner 186
`permitsAs a result, the client device 120 tocan selectively and/or simultaneously display network content
`received by communications device 184 and TVtelevision programming content received by the TV tuner
`186.
`
`[0025] The general-purpose computer 170 maytypically will include an input/output interface 188 that
`enablesfor wired or wireless connection to various peripheral devices 190. Examples of peripheral
`devices 190 include, but are not limited to, a mouse 191, a mobile phone 192, a personal digital assistant
`193 (PDA), an MP3 player (not shown), a keyboard 194, a display monitor 195 with or without a touch
`screen input, a TV remote control 196 for receiving information from and rendering information to users,
`and an audiovisual input device 198.
`
`[0026] Although FIG. 1 illustrates devices such as a mobile telephone 192, a PDA 193, and a TV remote
`control 196 as being peripheral with respect to the general-purpose computer 170, in another
`implementation, such devices may themselves include the functionality of the general-purpose computer
`170 and operate as the client device 120. For example, the mobile phone 192 or the PDA 193 may
`include computing and networking capabilities and function as a client device 120 by accessing the
`delivery network 160 and communicating with the host system 110. Furthermore, the client system 105
`may include one, some or all of the components and devices described above.
`
`A graphical user interface, such as a tabbed IM user interface, may be displayed on the display monitor
`195 or other peripheral device 190. A tabbed IM user interface includes one or more tabs located
`adjacent to one another, and each tab is assigned to an IM session. An IM conversation counter and
`indicator may be provided for the tabbed IM user interface.
`
`[0027] Referring to FIG. 2, a communications system 200 is capable of delivering and exchanging data
`between a client system 105 and a host system 110 through a communications link 115. The client
`system 105 typically includes one or more client devices 120 and/or client controllers 125, and the host
`system 110 typically includes one or more host devices 135 and/or host controllers 140. For example, the
`client system 105 or the host system 110 may include one or more general-purpose computers (e.g.,
`personal computers), one or more special-purpose computers (e.g., devices specifically programmed to
`communicate with each other and/or the client system 105 or the host system 110), or a combination of
`one or more general-purpose computers and one or more special-purpose computers. The client system
`105 and the host system 110 may be arranged to operateoperated within or in concert with one or more
`other systems, such as, for example, one or more LANs ("Local Area Networks") and/or one or more
`WANs ("Wide Area Networks").
`
`[0028] The client device 120 and the host device 135 are generally capable of executing instructions
`under the command of, respectively, a client controller 125 and a host controller 140. The client device
`120 and the host device 135 are connected to, respectively, the client controller 125 and the host
`controller 140 by, respectively wired or wireless data pathways 130 and 145, which are capable of
`delivering data.
`
`[0029] The client device 120, the client controller 125, the host device 135, and the host controller 140
`typically each typically include one or more hardware components and/or software components. An
`example of a client device 120 or a host device 135 is a general-purpose computer (e.g., a personal
`computer) or software on such a computer capable of responding to and executing instructions in a
`defined manner. Other examples include a special-purpose computer, a workstation, a server, a device,
`
`Facebook's Exhibit No. 1007
`005
`
`Snap Inc. Ex. 1007 Page 0005
`
`

`

`a component, other physical or virtual equipment or some combination of these capable of responding to
`and executing instructions. The client device 120 and the host device 135 may include devices that are
`capable of establishing peer-to-peer communications.
`
`[0030] An example of client controller 125 or host controller 140 is a software application loaded on the
`client device 120 or the host device 135 for commanding and directing communications enabled by the
`client device 120 or the host device 135. Other examples include a program, a piece of code, an
`instruction, a device, a computer, a computer system, or a combination of these for independently or
`collectively instructing the client device 120 or the host device 135 to interact and operateoperated as
`described. The client controller 125 and the host controller 140 may be embodied permanently or
`temporarily in any type of machine, component, physical or virtual equipment, storage medium, or
`propagated signal capable of providing instructions to the client device 120 and the host device 135.
`
`[0031] The communications link 115 typically includes a delivery network 160 making a direct or indirect
`communication between the client system 105 and the host system 110, irrespective of physical
`separation. Examples of a delivery network 160 include the Internet, the World Wide Web, WANs, LANs,
`analog or digital wired and wireless telephone networks (e.g. Public Switched Telephone Network
`(PSTN), Integrated Services Digital Network (ISDN), and Digital Subscriber Line (PSTN, ISDN, and
`xDSL)), radio, television, cable, or satellite systems, and any other delivery mechanismsmechanism for
`carrying data. The communications link 115 may include communication pathways 150, 155 that enable
`communications through the one or more delivery networks 160 described above. Each of the
`communication pathways 150, 155 may include, for example, a wired, wireless, cable or satellite
`communication pathway.
`
`[0032] FIG. 3 illustrates a communications system 300 including a client system 105 communicating with
`a buddy client system 305 and an IM host system 310 through a communication link 115. Such a
`communications system may be used by users of IM service providers, such as, for example, AIM, ICQ,
`Yahoo Messenger, and Microsoft Messenger.
`
`[0033] In one implementation, the IM host system 310 may have characteristics similar to those
`described above with respect to host system 110, and the. The client system 105 and the buddy client
`system 305 may include communication software to enable users of the client systemsaccess to the IM
`host system 310 by users.
`
`[0034] TheIn general, the IM host system 310 may support IMsupports instant messaging services
`irrespective of a user's network or Internet access. Thus, the IM host system 310 may allowallows users
`to send and receive IMsinstant messages, regardless of whether they have access to any particular ISP.
`The IM host system 310 also may support associated services, such as administrative matters,
`advertising, directory services, chat, and interest groups related to the IMinstant messaging. The IM host
`system 310 has an architecture that enables the devicesmachines (e.g., servers) within the IM host
`system 310 to communicate with each other. To transfer data, the IM host system 310 employs one or
`more standard or exclusive IM protocols.
`
`[0035] To access the IM host system 310 to begin an IMinstant messaging session in the implementation
`of FIG. 3, the client system 105 establishes a connection to the IM host system 310. Once a connection
`to the IM host system 310 has been established, the client system 105 may directly or indirectly transmit
`data to and access content from the IM host system 310. By accessing the IM host system, a user can
`use the IM client application to view whether particular users ("buddies") are online, exchange IMsinstant
`messages with particular buddies, participate in group chat rooms, trade files such as pictures, invitations
`or documents, find other buddies with similar interests, get customized information such as news and
`stock quotes, and search the Web. Buddy client system 305 may be similarly manipulated to establish a
`contemporaneous connection with IM host system 310.
`
`[0036] Once connectivity is established,For example a user who is using client system 105 may view
`whether a buddy using buddy client system 305 is online, and typically may view whether the buddy is
`
`Facebook's Exhibit No. 1007
`006
`
`Snap Inc. Ex. 1007 Page 0006
`
`

`

`able to receive IMsinstant messages. If the buddy is online, the user may exchange IMsinstant messages
`with that buddy.
`[0037] In one implementation, the IMsinstant messages sent between client system 105 and buddy client
`system 305 are routed through IM host system 310. In another implementation, the IMsinstant messages
`sent between client system 105 and buddy client system 305 are routed through a third party server (not
`shown), and also may or may not be routed through IM host system 310. In yet another implementation,
`the IMsinstant messages are sent directly between client system 105 and buddy client system 305.
`
`[0038] Referring to FIG. 4, illustrates a communications system 400 including a client system 105
`communicating with a buddy client system 305 and an IM host system 310 interact according to a
`procedure 400 to provide a tear-off element for instant messaging (IM) applications or other online
`applications. The procedure 400 may be implemented by any type of hardware, software, device,
`computer, computer system, equipment, component, program, application, code, storage medium, or
`propagated signal. Furthermore, although not shown in FIG. 4, the client system 105 and the IM host
`system 310 may be directly or indirectly interconnected through known or described delivery networks,
`examples of which are described with respect to network 160. In one implementation, the procedure 400
`may be implemented in a client/host context, and the tear-off element may be provided for instant
`messaging (IM) applications or other online applications through a remote device in a client/host
`environment. In another implementation, the procedure 400 may be implemented in a standalone or
`offline client context, and the tear-off element may be provided for instant messaging (IM) applications or
`other online applications by the standalone/offline device and may be accessed or updated through a
`remote device in a non-client/host environment such as, for example, a LAN server serving an end user
`or a mainframe serving a terminal device. The procedure 400 may be implemented to provide tear-off
`elements for instant messaging (IM) applications or other online applications of any OSP or ISP.through
`a communication link 115. System 400 illustrates a possible implementation of the communications
`system 300 of FIG. 3.
`
`In the implementation shown in FIG. 4, the IM host system 310 includes a login server 470 for enabling
`access by users and routing communications between the client system 105 and other elements of the
`IM host system 310. The IM host system 310 also includes an IM server 490. To enable access to the IM
`host system 310 by users, the client system 105 and the buddy client system 305 include communication
`software, such as for example, an OSP client application and an IM client application. The OSP and IM
`communication software applications are designed to facilitate a user's interactions with the IM service.
`
`In general, the IM host system 310 supports instant messaging services irrespective of a user's network
`or Internet access. Thus, the IM host system 310 allows users to send and receive instant messages,
`regardless of whether they have access to any particular ISP. The IM host system 310 may support
`associated services, such as administrative matters, advertising, directory services, chat, and interest
`groups related to the instant messaging. The IM host system 310 has an architecture that enables the
`machines (e.g., servers) within the IM host system 310 to communicate with each other. To transfer data,
`the IM host system 310 employs one or more standard or exclusive IM protocols.
`
`To access the IM host system 310 to begin an instant messaging session in the implementation of FIG.
`4, the client system 105 establishes a connection to the login server 470. The login server 470 typically
`determines whether the particular user is authorized to access the IM host system 310 by verifying a user
`identification and password. If the user is authorized to access the IM host system 310, the login server
`470 usually employs a hashing technique on the user's screen name to identify a particular IM server 490
`within the IM host system 310 for use during the user's session. The login server 470 provides the client
`system 105 with the IP address of the IM server 490, gives the client system 105 an encrypted key (e.g.,
`a cookie), and breaks the connection. The client system 105 then uses the IP address to establish a
