TCL’S INVALIDITY CONTENTIONS FOR U.S. 8,078,767
`Exhibit C6: U.S. Patent No. 8,078,766 (“Takenaka”)
`
`
`As demonstrated in the claim charts below, the asserted claims of U.S. Patent No. 8,078,767 (“the ’767 patent”) are invalid (a) under
`one or more sections of 35 U.S.C. § 102 as anticipated by Takenaka and (b) under 35 U.S.C. § 103(a) as obvious over Takenaka
`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 C1-C14, and O3, 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 ’767 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.

`constituted of a USB transceiver for executing any serial communication with connected external
`device, serial interface engine (SIE) for executing communication control processing corresponding to
`USB protocol, and the like. The control unit 151 communicates the USB interface unit 153 and when
`detecting that an external device connects the USB interface unit 153, the control unit 151 executes a
`configuration setting to read out address setting of the connected external device and various kinds of
`pieces of information stored in the connected external device.”); see also 6:42-52.

`information stored in the connected external device. When detecting that an external device is USB
`device that can correspond to the apparatus of displaying the image (the television receiver) based on
`the read information, the control unit 151 communicates this external device to read the image data
`VSusb out of the external device and supply it to the image changeover unit 131, thereby enabling
`image stored in the external device to be displayed on the image display unit 136.”)
`
`6:42-52 (“At step ST1, the control unit 151 determines whether or not the television receiver 100
`connects an external device. When the control unit 151 determines that the television receiver 100
`connects the external device, the operation goes to step ST2. When the control unit 151 determines
`that the television receiver 100 connects no external device, the operation goes back to the step ST1. It
`is to be noted that the control unit 151 may determine whether or not the television receiver 100
`connects an external device based on facts whether or not a D+terminal or a D-terminal of USB
`connector provided in the USB interface unit 153 has a predetermined voltage level.”); see also FIG.

`external device has been released. If the external device keeps on connecting the television receiver
`100, the operation goes back to the step ST11 where the message PM3 keeps on displaying. If the
`connection of the external device has been released, for example, a USB cable has been released from
`a USB connector in the USB interface unit 153 or a USB connector in the external device, the
`operation goes to step ST15 where the control unit 151 finishes displaying the indication. The
`operation then goes back to the step ST1.”)
`
`To the extent 35 U.S.C. § 112, ¶6 applies, Takenaka also discloses the corresponding structure(s) and
`function(s) claimed or their equivalents, as shown above, or renders them obvious in view of the
`knowledge of one skilled in the art.
`
`To the extent that Plaintiff alleges that Takenaka does not explicitly disclose this claim limitation, this
`limitation is inherent and/or it would have been obvious in view of the knowledge of a person of
`ordinary skill in the art, AAPA, and/or in view of the references identified in Exhibits C1-C14 and O3.
`
`Defendants incorporate by reference their contentions relating to claim 6, as if fully set forth herein.
`
`Takenaka discloses a display apparatus characterized in that said control unit controls to end the
`display after a predetermined first period elapses.
`
`For example, Takenaka discloses:
`
`5:28-33 (“The image-output-processing unit 135 outputs the image output signal VSg as an output
`signal Vout having any format corresponding to an external device, not shown, when the image-
`output-processing unit 135 supplies an image signal to the external device.”)
`
`5:64-6:19 (“The control unit 151 also connects the above-mentioned various units through a bus 154.
`The control unit 151 generates the control signal CT based on the manipulation signal PS received
`from the user interface unit 152 and supplies the control signal CT to the above-mentioned various
`units through a bus 154, which enables the television receiver 100 to operate corresponding to the
`
`7.pre
`
`7.a
`
`The display apparatus
`according to claim 6,
`
`characterized in that said
`control unit controls to end
`the display after a
`predetermined first period
`elapses.

`

`user's manipulations. For example, when the manipulation signal PS received from the user interface
`unit 152 indicates that the user manipulates any signal changeover such as channel changeover,
`broadcast changeover, or input changeover, the control unit 151 controls the tuning/demodulation unit
`112 for satellite broadcasting and the tuning/demodulation unit 114 for terrestrial broadcasting to
`select a desired channel thereof or controls the demultiplexer 121, the image changeover unit 131, and
`the audio changeover unit 141 to perform their changeover operations, in order to enable to be
`presented image and/or audio of the desired channel or the desired broadcast system, or image and/or
`audio received from an external device. The control unit 151 further generates a control signal for
`displaying EPG or the like based on the broadcast data DTd received from the demultiplexer 121 and
`supplies such the control signal to the signal-generating unit 133.”)
`
`8:8-14 (“At the step ST6, the control unit 151 determines whether or not the external device has mass
`storage class. If the class checked at the step ST5 is included in the mass storage class, namely, its
`device class code is “00h” and its interface class code is “08h”, the operation goes to step ST9. If the
`class checked at the step ST5 is not included in the mass storage class, the operation goes back to step
`ST7.”)
`
`8:61-9:4 (“At the step ST11, the control unit 151 determines whether or not the connection of the
`external device has been released. If the external device keeps on connecting the television receiver
`100, the operation goes back to the step ST11 where the message PM3 keeps on displaying. If the
`connection of the external device has been released, for example, a USB cable has been released from
`a USB connector in the USB interface unit 153 or a USB connector in the external device, the
`operation goes to step ST15 where the control unit 151 finishes displaying the indication. The
`operation then goes back to the step ST1.”
