Full Citation: U.S. Utility patent application Ser. No. 13/163,614
Publication/Filing Date: Filed on June 17, 2011.
Brief Description: Titled "Automatic Webpage Characterization and Search Results Annotation," this application introduces the foundational concepts of analyzing webpages referenced by search results, characterizing their content and composition, and annotating the search results to convey these characteristics to the user.
Potentially Anticipates Claim(s) under 35 U.S.C. § 102: Given that 11100184 is a continuation of this application, the prior art likely anticipates elements of all independent claims (Claims 1, 7, 12, 17, and 19) relating to the core idea of analyzing, characterizing, and annotating search results to provide users with information about referenced webpages. Specifically, the general methods and systems for displaying search results with annotations, as described in the claims, would find their genesis here.

Brief Description: Titled "Automatic Webpage Characterization and Search Results Annotation," this application builds upon the previous one, further developing the methods and systems for analyzing and annotating search results based on webpage characteristics.
Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This continues to anticipate aspects of all independent claims (Claims 1, 7, 12, 17, and 19), particularly those concerning the automatic characterization and annotation of webpages in search results. The evolution of the annotation types and criteria for characterization likely find their basis in this application.

Brief Description: Titled "Automatic Webpage Characterization and Search Results Filtering," this application introduces the additional functionality of filtering search results based on the determined webpage characteristics, alongside annotation.
Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This application is highly relevant to claims involving filtering. Specifically, it would anticipate aspects of Claims 3, 4, 8, 9, 13, 14, 21, and 22, which describe selectable filtering functions and the removal of search result groupings. The filtering criteria and the underlying characterization process for filtering would be established here.

Brief Description: Titled "Internet Search Results Annotation for Missing Search Terms in Descendant Webpages," this application specifically addresses the annotation of search results to indicate the presence or absence of search terms not only on the primary referenced webpage but also on its descendant webpages.
Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This application directly anticipates elements in Claims 6, 11, 16, 17, and 20, which detail the handling and annotation concerning search terms found in descendant webpages, and how "fourth type" results (where terms are missing from both the primary and descendant pages) are treated.

Brief Description: Titled "Internet Search Results Annotation and Filtering for Missing Search Terms," this application further refines the annotation and filtering mechanisms specifically related to missing search terms.
Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This application would anticipate the refined aspects of annotation and filtering for missing search terms as described in the independent claims (1, 7, 12, 17, and 19), particularly as they relate to explicitly showing missing search terms in annotations and using this as a basis for filtering.

Publication/Filing Date: Filed on February 13, 2020.
Brief Description: Titled "Internet Search Results Annotation for Search Term Elements Present or Absent in Referenced Webpages and Descendant Webpages," this application further elaborates on the annotation of search results to indicate the presence or absence of search term elements on both referenced and descendant webpages.
Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This application, being a direct continuation, is highly likely to anticipate the detailed methods and systems for annotating based on the presence or absence of search terms in both referenced and descendant webpages, as found throughout the independent claims of US11100184B2, particularly Claims 1, 6, 7, 11, 12, 16, 17, 19, and 20.
