Ex. 5, p. 13	¶37	col. 3:52-61
displaying at least one corresponding thumbnail image of the video at a prescribed area of the display, wherein the prescribed area is above the progress bar.	The accused products display a row of thumbnail images in an area located spatially above the progress bar during the scrubbing action Compl. Ex. 5, p. 15	¶37	col. 4:1-5

Identified Points of Contention

Scope Questions: A central question may be the construction of "prescribed area... is above the progress bar." The dispute could focus on whether the specific layout and behavior of the Roku interface falls within the scope of this spatial limitation as defined in the patent.
Technical Questions: The analysis may turn on how the Roku OS "associates" thumbnail images with "prescribed locations." The court will need to determine if Roku's method of generating and linking these preview images for its scrubbing feature matches the method contemplated by the claim.

'066 Patent Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
An image display device, comprising: a display; an external interface configured to be connected to an external device,	The accused Roku televisions include a display and external interfaces such as HDMI ports for connecting external devices Compl. Ex. 6, pp. 3-5	¶51	col. 7:5-8
a controller configured to: display an external source list menu including external device information for identifying the external interface,	The Roku OS home screen acts as a menu listing available inputs, such as "Computer (HDMI 2)," which identifies the external interface Compl. Ex. 6, p. 10	¶51	col. 8:35-41
based on the image display device being connected to the external device, display, on a position corresponding to the external device information in the external source list menu, a moving image as the external device information,	When a device is connected, the controller displays a live "moving image" from that source in the corresponding tile on the home screen Compl. Ex. 6, p. 10	¶51	col. 8:41-47
wherein the moving image is displayed after receiving a command signal from a remote controller.	This functionality is invoked by user interaction via the Roku remote controller to navigate the home screen menu Compl. Ex. 6, p. 11	¶51	col. 8:47-49

Identified Points of Contention

Scope Questions: A key dispute will likely be whether the tile-based graphical user interface of the Roku home screen qualifies as an "external source list menu" as the term is used in the patent, which illustrates a more traditional text-based list.
Technical Questions: The infringement analysis may focus on the sequence of operations. The claim requires displaying the moving image "based on" the connection and "after receiving a command signal." The court may examine whether the Roku OS performs these steps in the specific manner and sequence required by the claim.

V. Key Claim Terms for Construction

For the '918 Patent:

The Term: "prescribed area of the display, wherein the prescribed area is above the progress bar" (from claim 3)
Context and Importance: This term is critical as it defines the spatial relationship between the thumbnail preview and the progress bar. The infringement analysis will depend on whether this requires a fixed, non-overlapping area located strictly "above" the bar, a configuration the complaint alleges the accused products possess Compl. Ex. 5, p. 15
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification generally describes displaying the thumbnail to allow a user to preview the content, suggesting the exact location may be secondary to the function '918 Patent, col. 2:5-13 Parties may argue "above" could mean "not obscured by" or "in a different vertical plane than."
- Evidence for a Narrower Interpretation: Figure 3 of the patent explicitly depicts the thumbnail image (213) in a box located spatially above and separate from the progress bar (200) '918 Patent, Fig. 3 A defendant may argue this embodiment limits the term to a distinct, non-adjacent vertical position.

For the '066 Patent:

The Term: "external source list menu" (from claim 1)
Context and Importance: This term defines the fundamental user interface element at issue. The case may turn on whether Roku's graphical, tile-based home screen is equivalent to the claimed "list menu." Practitioners may focus on this term because the visual evidence in the patent differs from the accused product's interface.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The abstract and summary describe the invention in functional terms, focusing on displaying information for an external device to allow for easy recognition, which the Roku home screen arguably does '066 Patent, abstract '066 Patent, col. 2:3-11 This could support an interpretation where any UI that lists external sources qualifies.
- Evidence for a Narrower Interpretation: Figure 2 of the patent explicitly illustrates a text-based, numbered list format (e.g., "1.
