Obviousness

Obviousness under 35 U.S.C. § 103 requires an analysis of whether the differences between the claimed invention and the prior art would have been obvious to a person having ordinary skill in the art (PHOSITA) at the time the invention was made (or before the effective filing date for AIA applications). This involves considering the scope and content of the prior art, the differences between the claimed invention and the prior art, the level of ordinary skill in the art, and any secondary considerations of non-obviousness. A key aspect is identifying a motivation to combine prior art references to arrive at the claimed invention, along with a reasonable expectation of success. A PHOSITA is a hypothetical person with ordinary skill and creativity in the relevant technical field, not a genius or an inventor.

The patent US11812091, titled "Multimedia player displaying operation panel depending on contents," focuses on automatically displaying context-relevant operation panels for digital content. The priority date for this patent is August 30, 2005.

Person Having Ordinary Skill in the Art (PHOSITA)

For US11812091, a PHOSITA would likely be an engineer or developer with practical experience in multimedia systems, user interface design, and digital content reproduction, particularly in the context of broadcasting and networked content delivery (e.g., VOD). This individual would be familiar with:

• Digital content reproduction apparatuses (e.g., HOD/DVD decoders, set-top boxes, personal computers capable of multimedia playback).
• Principles of graphical user interfaces (GUIs) and remote control design.
• Protocols and standards for digital broadcasting (e.g., Japanese terrestrial digital broadcasting, PSI, PMT, data encode descriptors like auto_start_flag).
• Network communication for content delivery (e.g., VOD services).
• Programming concepts for controlling display elements based on content metadata.

The PHOSITA would possess the capability of understanding the scientific and engineering principles applicable to multimedia reproduction and user interaction, and be able to combine known elements and apply conventional wisdom in a predictable manner.

Potential Combinations of Prior Art References for Obviousness

To establish obviousness, one must demonstrate that the prior art discloses all elements of the claims and that there would have been a motivation for a PHOSITA to combine those references with a reasonable expectation of success. Simply showing that elements exist in the prior art is not sufficient; a clear reason or rationale for combining them must be provided.

Given the patent's emphasis on dynamically switching operation panels based on content type and related information (including time-related information), the following prior art references, explicitly cited in US11812091, are relevant:

1. JP-A-2005-73022:

• Disclosure: This reference describes a broadcast receiving apparatus that provides a user with "illumination of a usable key of a remote controller in accordance with information on digital contents."
• Relevance to US11812091: This reference establishes the concept of adapting user interfaces (specifically remote control keys) based on the type of digital content being reproduced. It addresses the problem of too many keys and improving user-friendliness, which is also a stated object of US11812091.

2. General GUI-based Digital Content Reproduction Apparatuses (e.g., digital broadcasting compatible personal computers and DVD reproduction compatible personal computers):

• Disclosure: The background of US11812091 acknowledges that these apparatuses "display reproduction keys for linear contents and interactive contents on a screen and unusable keys are disabled so that it is possible to improve user easy to use performance."
• Relevance to US11812091: This implicitly discloses the display of operation panels (GUI-based) for both linear and interactive content, and the concept of disabling irrelevant keys to enhance usability.

Proposed Combination 1: JP-A-2005-73022 + General GUI-based Digital Content Reproduction Apparatuses

• Rationale for Combination: A PHOSITA, seeking to improve the user experience and reduce the complexity of operating multimedia players, would have been motivated to combine the concept of content-dependent key adaptation from JP-A-2005-73022 with the GUI-based operation panels common in digital broadcasting compatible PCs and DVD players. The problem JP-A-2005-73022 addresses (too many keys on a remote) is analogous to the problem of a "wide operation panel rendering area" when all keys are displayed in a GUI, as noted in US11812091's background.
• How the Combination Renders Claims Obvious:
  • Alternative Display of Panels (Claim 1 & 14): JP-A-2005-73022 teaches adapting keys based on content, and general GUI apparatuses display both linear and interactive content keys. A PHOSITA, wanting to optimize screen space and usability, would naturally switch between distinct operation panels (e.g., a "linear content operation panel" and an "interactive content operation panel") rather than merely disabling keys on a single, large panel. This directly leads to the "alternatively display either of a first operation panel... or a second operation panel" limitation. The patent itself highlights that in conventional GUI systems, displaying all keys requires a "large panel rendering area," thus indicating the motivation to make the panel smaller.
  • Content-Dependent Control: Both references provide the foundational concept of changing the user interface based on the type of digital content (e.g., linear vs. interactive). JP-A-2005-73022 uses "information on digital contents" to illuminate keys, while general GUIs display different sets of keys for linear and interactive content.
  • Network Communication & Decoder (Claim 1 & 14): The apparatuses described in the prior art (broadcast receivers, digital broadcasting compatible PCs, DVD decoders) inherently include network communication (or broadcast reception, which is analogous in terms of content delivery) and decoders for digital content. Claim 14's specific mention of a VOD server is an obvious variation, as networked content delivery was well-known at the priority date, and VOD is a specific type of network content.
  • Time-Related and Panel-Related Information (Claim 1 & 14): While these specific terms might not be explicitly present, the concept of "information on digital contents" (from JP-A-2005-73022) and the inherent nature of different content types (linear vs. interactive) in general GUI systems would provide the basis for determining which panel to display. Introducing "time-related information" (e.g., an appreciation term) to further refine the display logic, especially for data broadcasting with a limited lifespan, would be a predictable design choice for a PHOSITA optimizing content delivery and user experience, particularly given that the patent states that "Information on data added digital broadcasting includes up-to-date news, weather forecast and the like. There arises an issue of a lapse of an appreciation term, when reproduction is made." This explicitly points to an existing problem that a PHOSITA would seek to solve with known information.

3. MPEP 2141.03 (R-01.2024): Level of Ordinary Skill in the Art

• Disclosure: "A person of ordinary skill in the art is also a person of ordinary creativity, not an automaton." This means the PHOSITA can combine teachings of multiple patents and apply common sense.
• Relevance to US11812091: This establishes that the combination outlined above does not require inventive genius, but rather ordinary creativity and problem-solving skills expected of a PHOSITA in the field.

Conclusion on Obviousness:

Based on the combination of JP-A-2005-73022 and the general knowledge of GUI-based digital content reproduction apparatuses, a PHOSITA would have been motivated to combine these teachings to create a system that automatically and exclusively displays context-relevant operation panels. The objective of improving user-friendliness and optimizing screen space, clearly articulated in the patent itself, would have provided the necessary motivation to move from merely disabling keys on a large panel to displaying distinct, smaller, and automatically switched panels. The inclusion of "time-related information" to manage content with an "appreciation term" (e.g., news) would be a logical refinement for a PHOSITA working in multimedia content delivery, addressing a known issue with such content. Therefore, the core inventive concepts of US11812091, as defined in Claims 1 and 14, appear to be obvious.
