Prior art

U.S. Patent 10,867,001 (US10867001B2) is titled "Internet search results annotation for search term elements present or absent in referenced webpages and descendant webpages" and was published on December 15, 2020. The application number is US16/790,057, and it has a priority date of June 17, 2011.

Here's an analysis of the most relevant prior art cited within the patent document itself, along with potential anticipations under 35 U.S.C. § 102. The patent document provides a list of "Applications Claiming Priority" and "Related Parent Applications" which are continuations of the original priority application, indicating they cover related subject matter. The "Cited By" section lists patents that cite 10867001, which are generally not prior art to 10867001, but rather build upon it. The "Families Citing this family" section is also not directly prior art for 10867001.

Therefore, the most relevant prior art would be the family of patents that US10867001B2 claims priority from, as these represent earlier disclosures by the same inventor(s) on related subject matter. These documents are directly referenced within the "Cross-Reference To Related Applications" section of the patent's description.

Here are the details of the most relevant prior art identified from the patent's "CROSS-REFERENCE TO RELATED APPLICATIONS" section, as these are direct antecedents or related applications from which US10867001B2 derives priority:

1. U.S. Utility patent application Ser. No. 16/553,900

   • Full Citation: U.S. Utility patent application Ser. No. 16/553,900, titled "Internet Search Results Annotation and Filtering for Missing Search Terms".
   • Publication/Filing Date: Filed on August 28, 2019.
   • Brief Description: This application generally relates to annotating and filtering internet search results, specifically addressing the issue of missing search terms in referenced webpages.
   • Potentially Anticipates: This application is a direct continuation of earlier applications and is part of the same patent family. It likely anticipates elements of claims 1 and 14 (the method and system claims) related to generating annotations for missing search terms and potentially the filtering aspects in claim 9 and 22, as indicated by its title. Given it is an earlier application in the same chain, it is highly likely to anticipate the core novelty of US10867001B2 in some form.

2. U.S. Utility patent application Ser. No. 16/199,192

   • Full Citation: U.S. Utility patent application Ser. No. 16/199,192, titled "Internet Search Results Annotation for Missing Search Terms in Descendant Webpages".
   • Publication/Filing Date: Filed on November 25, 2018.
   • Brief Description: This application specifically focuses on the annotation of search results when search terms are missing in referenced webpages but present in descendant webpages.
   • Potentially Anticipates: This application is directly relevant to claims 5, 6, 18, and 19 of US10867001B2, which describe scenarios where annotations are not generated if missing search terms are found in descendant webpages, and the definition of a descendant webpage. It also anticipates aspects of the broader claims (1 and 14) that involve the analysis of descendant webpages.

3. U.S. Utility patent application Ser. No. 15/383,907

   • Full Citation: U.S. Utility patent application Ser. No. 15/383,907, titled "Automatic Webpage Characterization and Search Results Filtering".
   • Publication/Filing Date: Filed on December 19, 2016.
   • Brief Description: This application deals with the automatic characterization of webpages and filtering of search results based on these characteristics.
   • Potentially Anticipates: This application likely anticipates elements of claims 9 and 22, which relate to the filtering function for removing search results. It also underpins the broader concept of analyzing and characterizing webpages, as mentioned in the summary and description of US10867001B2.

4. U.S. Utility patent application Ser. No. 14/820,433

   • Full Citation: U.S. Utility patent application Ser. No. 14/820,433, titled "Automatic Webpage Characterization and Search Results Annotation".
   • Publication/Filing Date: Filed on August 6, 2015.
   • Brief Description: This application focuses on the automatic characterization of webpages and the subsequent annotation of search results.
   • Potentially Anticipates: This application would significantly anticipate claims 1 and 14 of US10867001B2, particularly the aspects concerning the analysis of webpages and the generation of annotations for display. The title directly indicates the core functionality of annotation.

5. U.S. Utility patent application Ser. No. 13/163,614

   • Full Citation: U.S. Utility patent application Ser. No. 13/163,614, titled "Automatic Webpage Characterization and Search Results Annotation".
   • Publication/Filing Date: Filed on June 17, 2011.
   • Brief Description: This is the earliest application in the priority chain and introduces the fundamental concepts of automatic webpage characterization and search results annotation.
   • Potentially Anticipates: As the foundational application, this likely anticipates the broadest elements of claims 1 and 14 of US10867001B2 regarding the method and system for receiving search terms, analyzing webpages, and annotating search results based on specific characteristics. Its priority date also establishes the earliest effective date for much of the invention's core concepts.

These priority applications represent the most direct prior art as they form the continuous prosecution history leading to US10867001B2, and therefore their disclosures are critical in determining the novelty and non-obviousness of the claims in the granted patent.
