To provide a detailed analysis of US patent 11961422 regarding patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date, I need to access the official USPTO records for this specific patent.

My search for "US11961422 PTA PTE continuation divisional related family members expiration date site:uspto.gov" did not directly return a USPTO patent page or its prosecution history with these specific details. The USPTO website provides tools to search for patent assignments and other patent data, but direct programmatic access to individual patent prosecution histories, including PTA/PTE calculations and family relationships, is typically done through their Public Patent Application Information Retrieval (Public PAIR) system or the Open Data Portal. These systems often require specific queries or direct navigation that cannot be fully replicated in my current environment for a real-time, in-depth look at a single patent's complete prosecution history.

Without direct access to the full prosecution history from the USPTO for US11961422, I cannot definitively detail any granted PTA or PTE, nor can I confirm all continuation or divisional applications and their specific impacts on the patent term.

However, based on the general rules for U.S. utility patents, I can state the following:

  • Patent Term: For U.S. utility patents filed on or after June 8, 1995, the standard patent term is 20 years from the filing date of the earliest U.S. non-provisional or PCT application to which priority is claimed.
  • Patent Term Adjustment (PTA): PTA may be awarded by the USPTO to compensate for delays during patent prosecution. This adjustment is added to the 20-year term. Information about PTA is typically listed on the front page of the patent.
  • Patent Term Extension (PTE): PTE is primarily available for patents covering products, particularly pharmaceuticals, that have undergone regulatory review delays. It is limited to one patent per approved product and a maximum of 5 years. A PTE certificate is filed in the patent's file history.
  • Continuation and Divisional Applications: If a patent is granted on a continuation or divisional application, its term generally expires 20 years from the effective filing date of the earliest U.S. non-provisional or PCT application in the family to which it claims priority.

The patent itself (US11961422B2) indicates a "Prior art date" of 2021-05-14 and a "Filing date" of 2023-01-30. It also states "Priority date (The priority date is an assumption and is not a legal conclusion. Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.) 2021-05-14". This indicates that the 2023-01-30 filing date might not be the earliest effective filing date for term calculation purposes if it claims priority to an earlier non-provisional application or PCT application from 2021-05-14.

Without accessing the official USPTO prosecution history via Public PAIR or the Open Data Portal for US11961422, I cannot provide precise details on:

  • The exact Patent Term Adjustment (PTA) granted, if any.
  • Whether any Patent Term Extension (PTE) has been applied for or granted.
  • A definitive list of all continuation or divisional applications.
  • The exact earliest effective filing date used for term calculation, which would be crucial for determining the precise expiration date.
  • Other related family members beyond what is explicitly listed on the patent's front page as "Other versions" (US20230177980A1) or within the "Priority date" information (US18/103,234, US18/595,094, US18/667,712, US18/667,677).

However, the Google Patents page for US11961422B2 lists an "Anticipated expiration" date of 2042-05-13. This date is likely calculated based on the 20-year term from the earliest priority date (2021-05-14) plus any PTA.
