Most Relevant Prior Art for US Patent 7844889

Here's an analysis of the prior art cited in US Patent 7844489, focusing on its potential anticipation of claims under 35 U.S.C. § 102.

The patent US7844889 itself refers to several related applications in its "RELATED APPLICATIONS" section, which can be considered as prior art in some contexts due to their filing dates. These are:

• U.S. Non-provisional application Ser. No. 09/878,097 (issued as U.S. Pat. No. 7,210,099)

  • Full Citation: U.S. Pat. No. 7,210,099, filed Jun. 8, 2001, entitled “RESOLUTION INDEPENDENT VECTOR DISPLAY OF INTERNET CONTENT.”
  • Publication/Filing Date: June 8, 2001 (Filing Date).
  • Brief Description: This patent is a direct continuation of 09/878,097 and Continuation-in-Part of 09/828,511. It generally describes methods and apparatus for zoom-enabling the display of Internet content by retrieving and translating HTML, XML, and other Internet content into vector representations. It also discusses client-side processing using a rendering engine for scaling, zooming, and panning page layout information, and generating display lists and bounding boxes for text and images.
  • Potential Anticipation: This patent is a direct antecedent. Therefore, the core concepts of translating web content to scalable vector representations, generating display lists with vectors and bounding boxes, and client-side rendering with user-selected zoom and pan would be anticipated by 7,210,099, especially for claims 1, 16, and 21.

• U.S. Non-provisional application Ser. No. 09/828,511 (Abandoned)

  • Full Citation: U.S. Non-provisional application Ser. No. 09/828,511, filed Apr. 7, 2001, entitled “RESOLUTION INDEPENDENT VECTOR DISPLAY OF INTERNET CONTENT.”
  • Publication/Filing Date: April 7, 2001 (Filing Date).
  • Brief Description: This is an earlier application with a similar title and subject matter to 7,210,099. Although abandoned, its content may still be prior art if publicly accessible at the time. It likely covers the foundational ideas of resolution-independent display of Internet content using vector representations.
  • Potential Anticipation: If its content was publicly available as of its filing date (April 7, 2001), it would anticipate claims 1, 16, and 21 of US7844889 regarding the fundamental method, system, and computer-readable medium for resolution-independent display of web content through vector translation and display manipulation.

• U.S. Provisional Application No. 60/211,019

  • Full Citation: U.S. Provisional Application No. 60/211,019, filed Jun. 12, 2000, entitled “METHOD AND SYSTEM FOR RESOLUTION INDEPENDENT DISPLAY OF HTML AND XML CONTENT.”
  • Publication/Filing Date: June 12, 2000 (Filing Date).
  • Brief Description: This provisional application claims to describe a method and system for resolution-independent display of HTML and XML content. This would likely lay the groundwork for converting markup language content into a displayable format that can be adjusted for different resolutions.
  • Potential Anticipation: Given its title and early filing date, this provisional application would very strongly anticipate the core concepts of claims 1, 16, and 21, specifically regarding the handling of HTML and XML content for resolution-independent display. This includes the translation of content and its subsequent rendering.

• U.S. Provisional Application No. 60/217,345

  • Full Citation: U.S. Provisional Application No. 60/217,345, filed Jul. 11, 2000, entitled “METHOD AND SYSTEM FOR SELECTION, RETRIEVAL, AND CONVERSION OF COMPUTER CONTENT TO VECTOR FORMAT FOR RESOLUTION INDEPENDENT DISPLAY.”
  • Publication/Filing Date: July 11, 2000 (Filing Date).
  • Brief Description: This provisional application focuses on the selection, retrieval, and conversion of computer content into a vector format for resolution-independent display. This highlights the process of obtaining the content and transforming it into a scalable representation.
  • Potential Anticipation: This provisional application would anticipate elements of claims 1 and 16 that deal with the retrieval of web content and its conversion into a scalable vector representation for resolution-independent display, as well as the storage medium of claim 21 related to these operations.

• U.S. Non-provisional application Ser. No. 11/045,649 (issued as U.S. Pat. No. 7,584,423)

  • Full Citation: U.S. Pat. No. 7,584,423, filed Jan. 28, 2005, entitled “METHOD, PROXY AND SYSTEM TO SUPPORT FULL-PAGE WEB BROWSING ON HAND-HELD DEVICES.”
  • Publication/Filing Date: January 28, 2005 (Filing Date).
  • Brief Description: This patent, a divisional of 09/878,097, specifically addresses supporting full-page web browsing on hand-held devices, implying techniques for adapting web content to smaller screens while maintaining usability, likely through scaling and panning.
  • Potential Anticipation: This patent would likely anticipate aspects of claims 1, 16, and 21 related to the display of web content on client devices of varying resolutions, particularly hand-held devices, and the underlying methods and systems to achieve this, including scaling and panning.

• U.S. Non-provisional application Ser. No. 11/045,757 (issued as U.S. Pat. No. 7,461,353)

  • Full Citation: U.S. Pat. No. 7,461,353, filed Jan. 28, 2005, entitled “SCALABLE DISPLAY OF INTERNET CONTENT ON MOBILE DEVICES.”
  • Publication/Filing Date: January 28, 2005 (Filing Date).
  • Brief Description: Another divisional of 09/878,097, this patent directly describes the scalable display of Internet content on mobile devices. This would explicitly cover the core functionality of US7844889 for mobile contexts.
  • Potential Anticipation: Similar to 7,584,423, this patent would directly anticipate the aspects of claims 1, 16, and 21 concerning scalable display of Internet content, especially on mobile devices, including the methods for scaling and rendering, and the system components involved.

It's important to note that the benefit of the filing dates of these earlier applications is claimed by US7844889, which means they are considered part of the same patent family and are highly relevant.
