Obviousness Analysis under 35 U.S.C. § 103

The independent claims of US9055255 (e.g., Claim 1, which defines a method) describe running a live TV application on an intelligent TV, presenting live TV broadcast content, receiving input, determining a feature to present, and then presenting that feature in a second portion of the display that overlaps the live TV broadcast content.

Claim 1 of US9055255 states:
A method comprising:
a. running, via a processor associated with an intelligent television (TV), a live TV application, wherein the live TV application is configured to control one or more interactive user functions of the intelligent TV;
b. presenting, simultaneously via a display of the intelligent TV, live TV broadcast content, wherein the live TV broadcast content is presented to a first portion of the display;
c. receiving a live TV application input at the intelligent TV;
d. determining, by the processor and in response to receiving the live TV application input, a live TV application feature to present via the display, wherein the one or more interactive user functions of the intelligent TV are controlled via the live TV application feature; and
e. presenting, via the display, the live TV application feature to a second portion of the display, wherein the second portion of the display overlaps at least a portion of the presented live TV broadcast content.

A combination of prior art references would render the claims of US9055255 obvious to a person having ordinary skill in the art (PHOSITA). Specifically, the combination of US20080034374A1 and US20120159496A1, potentially supplemented by US20120204221A1 and general knowledge of smart TV technology, appears to cover all essential elements of Claim 1.

Combination of Prior Art References:

1. US20080034374A1 (Interactive television display with a transparent region for presenting additional content to a user): This reference teaches an "interactive television display" capable of presenting "additional content" via a "transparent region" that overlays the primary content. This directly addresses the following elements of Claim 1:

   • "presenting, simultaneously via a display of the intelligent TV, live TV broadcast content, wherein the live TV broadcast content is presented to a first portion of the display": An interactive television display inherently shows primary TV content.
   • "presenting, via the display, the live TV application feature to a second portion of the display, wherein the second portion of the display overlaps at least a portion of the presented live TV broadcast content": This is explicitly taught by the "transparent region for presenting additional content to a user," where the "additional content" would constitute the "live TV application feature." The patent US9055255 itself defines a "panel" as being "translucent whereby the panel obscures but does not mask the underlying content being displayed in the display," which aligns with the concept of a transparent region.
   • "receiving a live TV application input" / "interactive user functions": The term "interactive television display" implies the capability to receive user input and control interactive functions.

2. US20120159496A1 (Apparatus and method for providing an application based television guide): This reference teaches "providing an application based television guide," which directly corresponds to:

   • "running, via a processor associated with an intelligent television (TV), a live TV application, wherein the live TV application is configured to control one or more interactive user functions of the intelligent TV": An application-based television guide is a prime example of a "live TV application" as it relates to live broadcast content. Such a guide is inherently configured to control interactive user functions, such as displaying program information, changing channels, or setting reminders. The "Intelligent TV" (or Smart TV) concept, as defined in US9055255, explicitly involves running applications and providing intuitive user interfaces for navigating content.
   • "determining, by the processor and in response to receiving the live TV application input, a live TV application feature to present via the display": An application-based TV guide necessarily determines what information (e.g., program details, schedule grids) to present based on user input (e.g., selecting a channel or time slot) and controls related interactive functions.

3. US20120204221A1 (Context-sensitive remote control user interface): This reference further reinforces the "receiving a live TV application input" element by detailing methods for user interaction with a television system, specifically through a "context-sensitive remote control user interface." This device would be a natural choice for providing input to the "live TV application" (e.g., the TV guide).

Motivation to Combine:

A PHOSITA in August 2012 would have been strongly motivated to combine the teachings of US20080034374A1 and US20120159496A1 for several reasons:

1. Advancements in Television Technology and User Experience: The concept of "Smart TVs" and "Intelligent TVs" was rapidly evolving, aiming to integrate internet and application functionalities with traditional broadcast television. The US9055255 patent itself highlights the goal of providing "seamless and intuitive user interfaces for navigating and/or executing the various features of the Smart TV". Overlaying interactive applications, like a TV guide, directly onto the live broadcast stream would enhance the user experience by allowing viewers to access information and controls without fully interrupting their primary viewing. This is a natural progression of user interface design.
2. Common GUI Practices: Displaying supplemental content, such as menus or information banners, as overlays (e.g., translucent panels) on top of primary video content was a well-established graphical user interface (GUI) technique by 2012. This is evidenced by various classifications cited in US9055255, such as H04N5/445 ("Receiver circuitry... for displaying additional information"), H04N5/45 ("Picture in picture"), and G06F2203/04804 ("Transparency, e.g. transparent or translucent windows"). Applying an "application based television guide" (US20120159496A1) to such an overlay display mechanism (US20080034374A1) would be a logical and desirable improvement.
3. Efficiency and Contextual Information: A TV guide is frequently accessed while watching live television. Presenting it in an overlapping, interactive panel, as taught by US20080034374A1, would allow users to quickly glance at schedules or get program details without having to navigate to a separate, full-screen menu, thus maintaining context and reducing cognitive load. This directly addresses the desire for "intuitive user interaction capability" of "Intelligent TVs".
4. Integration of Input Mechanisms: The integration of input devices, such as the remote control detailed in US20120204221A1, with interactive displays and applications was also a well-known area of development. A PHOSITA would readily understand how to adapt such an input mechanism to control an application-based TV guide displayed as an overlay.

In summary, a PHOSITA, aiming to improve the interactive capabilities and user experience of a television system, would have found it obvious to combine an "application based television guide" (US20120159496A1) with an "interactive television display with a transparent region for presenting additional content to a user" (US20080034374A1). This combination, further supported by the knowledge of remote control interfaces (US20120204374A1), directly anticipates the method claimed in US9055255.
