TCL’S INVALIDITY CONTENTIONS FOR U.S. 8,713,206
`Exhibit E3: U.S. Patent No. U.S. Patent Publication No. 2009/0005651 (“Nitta”)
`
`
`As demonstrated in the claim charts below, the asserted claims of U.S. Patent No. 8,713,206 (“the ’206 patent”) are invalid (a) under
`one or more sections of 35 U.S.C. § 102 as anticipated by Nitta and (b) under 35 U.S.C. § 103(a) as obvious over Nitta standing alone
`and as set forth herein, and/or combined with the knowledge of a person of ordinary skill in the art, Applicant’s Admitted Prior Art
`(“AAPA”), and/or the additional prior art references discussed in Exhibits E1-E14, and O5, the contents of which are hereby
`incorporated by reference into this chart. One of ordinary skill in the art, as of the alleged priority date of the ’206 patent, would have
`known to combine the prior art elements disclosed by the foregoing references using known methods, and to use these elements
`according to their established functions in order to achieve a known and predictable result.
`
`Except where specifically noted otherwise, this chart may apply the apparent interpretations of claim language as used by Plaintiff in
`its infringement contentions. Such use, however, does not imply that Defendants adopt or agree with Plaintiff’s interpretations in any
`way. Additionally, by providing contentions for claim preamble elements, Defendants do not take a position on whether the preamble
`is a claim limitation.

`(imager 100) according to the embodiment of the present invention. FIG. 6B shows a processing
`sequence of a known general USB connection device (slave). First, a state sequence in the case
`where, from the known general USB connection device (slave) connected via a USB cable to a host
`(PC) (step S421), the USB cable is disconnected and then reconnected will be described.
`Data communication using USB is performed between a host, such as a PC, and a device serving as a
`slave. In this example, the slave is the imager. As has been described above, the slave holds a table
`referred to as a descriptor describing its attributes. The host, such as a PC, which is USB-connected to
`the slave, obtains the descriptor from the USB connection device (slave) to identify a driver
`compatible with the slave. The host loads the identified driver and performs slave-compatible data
`communication.
`By transferring a right to access a recording medium in the slave (imager) to the host (PC), the PC
`serving as the host can process the recording medium in the slave (imager) in a manner similar to that
`in which the host (PC) processes a storage device, such as a hard disk, in the PC. The standard for
`controlling the connection of the storage device in the USB-compatible device to the PC and the
`data processing is referred to as the USB mass storage class.”)

`the USB connection is broken and the imager is disconnected from the class driver of the host
`(PC), the controller performs an operation to change from the mass storage mode to the normal
`mode. Specifically, after the disconnection from the class driver, medium recognition is performed to
`enable an application to be executed in the imager to access the recording medium (DVD in the
`example shown in FIG. 6B) in the imager, the access right to which has been transferred to the host
`(PC). When the medium recognition is performed, a content file on the medium is read by the
`application executed in the imager, and, for example, an index screen shown in step S422 of FIG. 6B
`is presented on the display unit. This is a state where the USB cable is disconnected from the USB

`a USB cable, a display unit 304, and a controller 305.
`The controller 305 displays a setting screen serving as a GUI for setting the data output mode
`for outputting data via the USB connector 303 on the display unit 304 and controls the
`information processing apparatus on the basis of information input to the GUI. That is, the
`display unit 304 serves also as an operation unit for receiving user operations.
`The controller 305 displays, as a GUI to be displayed on the display unit 304, a function selection
`screen enabling the user to select both the recording medium serving as an output data source from
`which data is output via the USB cable and the USB function (PC mode or PictBridge mode) to be
`executed, namely, the GUI screen 105 described with reference to FIG. 2. On the basis of selection
`information input on the function selection screen, the controller 305 performs the setting processing
`to output data recorded on the selected recording medium in accordance with the selected USB
`function (PC mode or PictBridge mode).”) ; see also 3:48-6:23; 18:8-23.
`1:49-57 (“The USB connection between the imager and the PC involves a communication
`specification (PC mode) such as the USB mass storage class or picture transfer protocol (PTP).
`In contrast, the USB connection between the imager and the printer involves the communication
`specification “PictBridge” standardizing the interface between PTP defining the transport layer
`and the application layer above the transport layer. Accordingly, different communication
`specifications are applied.”)

`3:42-47 (“The communication unit may output data to the external device via a universal serial bus
`(USB) cable according to the USB standard. When the USB cable is disconnected from the
`communication unit or the external device, the controller may maintain the mode of the
`information processing apparatus set at the time the USB cable was disconnected.”)
`12:59-65 (“Therefore, the user connects the USB cable 121 to the USB terminal 101 to establish a
`USB connection with the external device (PC 111 or printer 112). With this processing, a connection
`is established with the class driver associated with the connected external device, thereby
`returning to the USB connection state set prior to the disconnection of the USB cable 121.”)
`13:10-34 (“FIG. 6A shows a processing sequence of the information processing apparatus
`(imager 100) according to the embodiment of the present invention. FIG. 6B shows a processing
`sequence of a known general USB connection device (slave). First, a state sequence in the case
`where, from the known general USB connection device (slave) connected via a USB cable to a host
`(PC) (step S421), the USB cable is disconnected and then reconnected will be described.
`Data communication using USB is performed between a host, such as a PC, and a device serving as a
`slave. In this example, the slave is the imager. As has been described above, the slave holds a table
`referred to as a descriptor describing its attributes. The host, such as a PC, which is USB-connected to
`the slave, obtains the descriptor from the
