Prior art

To identify the most relevant prior art for US Patent 11809431, I will examine the "Cited By" section on the patent's Google Patents page, as this typically lists prior art references considered by the patent examiner.

Here's the most relevant prior art for US Patent 11809431, based on its citations:

1. US 10,061,812 B2

• Full Citation: US 10,061,812 B2 (Bradley et al.)
• Publication/Filing Date: The priority date for US11809431B2 is 2013-03-15, and it explicitly states "Priority claimed from US14/212,429," which ultimately led to patent US10061812B2. The publication date of US10061812B2 is September 4, 2018, and its filing date was March 14, 2014.
• Brief Description: This patent is titled "System and method for achieving goals" and appears to be a grandparent or related patent to US11809431. It describes systems and methods for tracking progression toward goals for clients, involving providers, data compilation, threshold determination, and alerts. This suggests a very similar underlying invention or earlier iteration of the same technology.
• Potential Anticipation (35 U.S.C. § 102): Given the shared title, inventors, and abstract content, US 10,061,812 B2 potentially anticipates all independent claims (Claim 1, Claim 13, and Claim 18) of US 11,809,431 if its teachings disclose each and every element of those claims. The description of receiving input for clients, assigning providers, compiling data, setting goals, determining if goals are met, and issuing alerts is highly similar to the core aspects of the independent claims in US 11,809,431. Specifically, it mentions "a system, method, server, and computer readable medium for tracking progression toward one or more goals," and details steps like "Input is received establishing one or more clients," "the one or more client(s) are individual(s) receiving treatment or assistance," "the data associated with the one or more clients are stored in a server available through one or more networks," "Each of the one or more clients are assigned to one or more providers in response to selections from an administrator," "Goals are set for each of the one or more clients," "Data associated with each of the one or more clients is compiled as received from the one or more providers in the server," and "Alerts are automatically communicated in response to the compiled data varying from a threshold to become significant for one of the one or more clients." This directly mirrors the elements found in Claims 1, 13, and 18.

Further analysis would require a detailed claim-by-claim comparison between US11809431 and US10061812B2 to pinpoint exact areas of anticipation or obviousness.
