Prior art

Here's an analysis of the most relevant prior art for US patent 11451883, based on the provided patent text and focusing on documents that predate its earliest priority date of June 20, 2005.

The earliest priority date for US11451883 is June 20, 2005, claimed from U.S. Provisional Patent Application No. 60/692,356. Therefore, any prior art must have an effective date before June 20, 2005, and not be part of the direct priority chain of US11451883.

The provided patent text references the following as related or foundational:

1. U.S. Pat. No. 4,592,546 to Fascenda et al.

• Full Citation: U.S. Pat. No. 4,592,546 to Fascenda et al.
• Publication/Filing Date: The provided text indicates this patent had "expiration" prior to the current invention, enabling new uses. The specific publication or filing date is not explicitly stated in the provided text. However, its mention as an expired patent enabling new technology indicates it predates US11451883's priority date.
• Brief Description: This patent broadly relates to systems that utilize a multicast network with cell phones and other mobile communication devices to enable television viewers to participate in games of skill, such as predicting aspects of a live event (e.g., a football play).
• Potential Anticipation (35 U.S.C. § 102): While Fascenda et al. establishes a foundational concept of interactive entertainment linked to television events via mobile devices, it likely does not anticipate the specific features claimed in US11451883. The key differentiating elements of US11451883, as found in its independent claims (e.g., claims 1, 20, 41, 62, 81, 102, and 123), include the detailed methodology for managing client resources and assets. Specifically, these claims involve:
  • Receiving a list of assets necessary for executing an application.
  • Comparing this list with a first set of assets already resident on the computing device.
  • Receiving only a second set of assets that are not already resident on the device.
  • Further refining this by prioritizing the second set of assets (e.g., into necessary and preferred assets).
    These granular asset management and differential downloading techniques are central to US11451883's invention and are not evident in the high-level description of Fascenda et al. as provided in the background of US11451883.

2. U.S. Provisional Patent Application Ser. No. 60/588,273 (and its non-provisional U.S. patent application Ser. No. 11/166,596)

• Full Citation: U.S. Provisional Patent Application Ser. No. 60/588,273. The non-provisional application derived from this provisional is U.S. patent application Ser. No. 11/166,596.
• Publication/Filing Date:
  • Provisional Application Ser. No. 60/588,273: Filed July 14, 2004. This date predates the earliest priority date of US11451883 (June 20, 2005).
  • Non-provisional Application Ser. No. 11/166,596: Filed June 24, 2005. While its filing date is after US11451883's priority, it claims priority from the July 14, 2004 provisional, making the content of the provisional effective prior art as of that earlier date.
• Brief Description:
  • Provisional 60/588,273 is entitled "A METHODOLOGY FOR PROVIDING ALL CONTESTANTS IN GAMES OF SKILL PLAYABLE ON CELL PHONES WITH THEIR CURRENT STANDING WHILE RECEIVING GAME CONTROL INFORMATION ONE-WAY VIA A ‘BROADCAST’ TRANSMISSION."
  • Non-provisional 11/166,596 is entitled "METHODS AND APPARATUS FOR DISTRIBUTED GAMING OVER A MOBILE DEVICE."
    Together, these describe systems for distributed games of skill played on cell phones, involving the reception of game control information (potentially via one-way broadcast) and providing participant standings.
• Potential Anticipation (35 U.S.C. § 102): These applications are highly relevant as they explicitly disclose "distributed gaming over a mobile device" and "games of skill playable on cell phones," aligning with the core application area of US11451883. The mention of "receiving game control information" suggests the transfer of data necessary for the game. However, similar to the analysis for Fascenda et al., the provided descriptions do not clearly articulate the specific asset management methodology found in US11451883's independent claims.
  The key differentiating elements of US11451883, such as receiving a list of assets, comparing it with resident assets, and only receiving the missing second set of assets (claims 1, 20, 41, 62, 81, 102, 123), particularly for optimizing memory and transmission efficiency, are not explicitly described in the titles or brief descriptions of 60/588,273 or 11/166,596. Furthermore, the emphasis on "one-way via a 'broadcast' transmission" in the provisional's title suggests a different interaction model compared to the client-server request-and-response model for asset delivery in US11451883. The prioritization of assets (e.g., necessary vs. preferred assets) for efficient memory utilization, as detailed in US11451883 (e.g., claims 3, 4, 24, 25, 45, 46, 64, 65, 85, 86, 106, 107, 125, 126), further distinguishes US11451883 from these prior art references based solely on their provided descriptions.

3. U.S. patent application Ser. No. 11/298,901

• Full Citation: U.S. patent application Ser. No. 11/298,901.
• Publication/Filing Date: Filed December 9, 2005.
• Brief Description: Entitled "A GAME OF SKILL PLAYED BY REMOTE PARTICIPANTS UTILIZING WIRELESS DEVICES IN CONNECTION WITH A COMMON GAME EVENT."
• Potential Anticipation (35 U.S.C. § 102): The filing date of this application (December 9, 2005) is after the earliest priority date of US11451883 (June 20, 2005). Unless this application claims an earlier priority date that precedes June 20, 2005 (which is not indicated in the provided text), it would not constitute anticipatory prior art under 35 U.S.C. § 102 against the claims of US11451883 that are supported by the June 20, 2005 priority date. Therefore, it is generally not considered relevant anticipatory prior art in this context.
