TCL’S INVALIDITY CONTENTIONS FOR U.S. 7,746,413
`Exhibit A2: U.S. Patent No. 7,234,111 (“Chu”)
`
`
`As demonstrated in the claim charts below, the asserted claims of U.S. Patent No. 7,746,413 (“the ’413 patent”) are invalid (a) under
`one or more sections of 35 U.S.C. § 102 as anticipated by Chu and (b) under 35 U.S.C. § 103(a) as obvious over Chu 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 A1, A3-A9, and O1, 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 ’413 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.

`
`Prior Art: U.S. Pat. No. 7,234,111 (“Chu”)
`
`Chu discloses a controlling method of an operation screen for operations of a remote control device.
`For example, Chu discloses:
`Abstract (“A system for dynamically adapting a presentation generated with a scalable application to a
`display screen of any of a plurality of heterogeneous device platforms is disclosed. The system
`includes a device platform and a transformation module. The device platform is one of the
`heterogeneous device platforms and includes a display screen. The device platform is operable to
`initiate generation of a hierarchical configuration representing a plurality of graphical user interface
`components. The transformation module is operable to selectively arrange the graphical user interface
`components on a page as a function of the hierarchical configuration. In the addition, the
`transformation module is operable to selectively transform the graphical user interface components to
`maximize the fill of the display Screen by the page. “)
`1:7-10 (“The present invention relates generally to graphical user interfaces (GUI) and, more
`particularly, to a scalable GUI architecture to adapt applications to the user interface of different
`heterogeneous device platforms.”)

`dependent pages. At least one of the device platform dependent pages may be selected to display the

`mouse, a touch screen, a keypad, audio capabilities or any other mechanism providing an interface for
`a user of one of the heterogeneous device platforms.”)
`6:35-51 (“Different heterogeneous device platforms may also include different input methods
