Prior art

To identify the most relevant prior art for US patent 11553055, I will access the patent's citation list. Since direct access to the USPTO database for live citation extraction isn't feasible here, I will rely on the provided patent text, which includes "Prior art keywords" and a "Links" section that typically leads to official patent data.

Based on the provided patent text, the "Prior art keywords" are listed as: entity, model, communication, communications, data. The patent also lists several "Other versions," which usually include related applications or publications, some of which may contain their own prior art citations. The most direct source for prior art cited by US11553055B2 would be within the patent document itself.

The patent US11553055B2 explicitly states: "This application is a division of U.S. patent application Ser. No. 16/015,935, filed Jun. 22, 2018, now U.S. Pat. No. 10,917,483, which claims the benefit of U.S. provisional application Nos. 62/523,419, 62/523,475, 62/523,452, 62/523,463, 62/523,490, and 62/523,507, each filed Jun. 22, 2017. U.S. patent application Ser. No. 16/015,935 and each of the above-indicated U.S. provisional applications are incorporated by reference as if fully set forth."

Therefore, these are the immediate family of prior art documents. To identify other relevant prior art (non-family), I would typically look at the "References Cited" section of the patent on the USPTO website or Google Patents. However, since the prompt specifies to only use the provided text as authoritative, and the full "References Cited" list is not explicitly provided in the text snippet, I cannot detail all prior art references.

To address the request within the constraints, I will identify the provided family prior art and mention that a complete analysis of cited prior art would require accessing the full "References Cited" section of the patent.

Most Relevant Prior Art (from patent family listed in description):

The patent US11553055B2 is a divisional application, and therefore directly related to:

• U.S. Patent No. 10,917,483
  • Full Citation: U.S. Pat. No. 10,917,483
  • Publication/Filing Date: Filed June 22, 2018 (as U.S. patent application Ser. No. 16/015,935).
  • Brief Description: This is the parent patent from which US11553055B2 is a divisional. It would cover similar or overlapping subject matter regarding systems for automated communication-based intelligence engines, including creating and maintaining entity models, clustering entities, and routing online conversations. The abstract for US11553055B2 largely mirrors the concepts likely present in its parent.
  • Potential Anticipated Claim(s): Given its direct relationship as a parent application, it potentially anticipates all independent claims (Claim 1, 11, 12, 18, 19) of US11553055B2, or at least covers the foundational aspects that would make the claims of US11553055B2 obvious extensions. The divisional nature implies that some claims in US11553055B2 were not allowed in US10917483 but were deemed patentable when pursued in a separate application.

In addition, the parent application (U.S. patent application Ser. No. 16/015,935) claims the benefit of several provisional applications. These provisional applications establish an earlier priority date for the subject matter disclosed within them.

  • Publication/Filing Date: Filed June 22, 2017.
  • Brief Description: As a provisional application, its content would likely describe an early version of the automated communication-based intelligence engine, entity modeling, or related aspects.
  • Potential Anticipated Claim(s): Potentially all claims of US11553055B2, depending on the scope of disclosure within this provisional application.

• U.S. Provisional Application No. 62/523,475

  • Full Citation: U.S. provisional application No. 62/523,475
  • Publication/Filing Date: Filed June 22, 2017.
  • Brief Description: Similar to the above, this provisional application would disclose aspects of the invention at an earlier stage.

A full and comprehensive prior art analysis would require examining the "References Cited" section of US11553055B2, which typically lists patents and non-patent literature considered by the examiner. Since this list is not provided in the prompt's text, I cannot enumerate those additional prior art documents.
