Extensions — US Patent 11722554

To provide a comprehensive overview of patent term adjustments, extensions, family members, and expiration date for US patent 11722554, I will use information available through the USPTO.

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) can extend the term of a patent to compensate for delays caused by the USPTO during the prosecution of a utility or plant patent application. These delays can include:

Failure to issue a first Office Action or notice of allowance within 14 months of filing.
Failure to respond to an applicant's reply to an Office Action within four months.
Failure to issue a patent within four months of the payment of the issue fee.
The application being pending for more than three years, with certain exclusions for applicant-caused delays.

Applicant delays can reduce any awarded PTA. The patent document itself or the USPTO Patent Center would provide the specific PTA calculation for US11722554.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are distinct from PTA and are generally available for patents claiming products (e.g., human drugs, medical devices, food additives, veterinary biological products) that require premarket regulatory approval from agencies like the FDA. This extension aims to restore patent term lost during the regulatory review process. There is no indication in the provided patent text that US11722554 relates to such products. Therefore, it is highly unlikely to have a PTE.

Continuation and Divisional Applications

The patent text for US11722554 explicitly states that it is a continuation of U.S. patent application Ser. No. 17/109,883, filed on December 2, 2020.

A continuation application is a second application for the same invention claimed in a prior-filed, co-pending nonprovisional application. It allows for new claims to be introduced and for further examination by the USPTO.
Divisional applications arise when an earlier application claimed two or more independent and distinct inventions.

The provided information indicates that US11722554 is a continuation, but does not explicitly mention any divisional applications.

Related Family Members

The patent states that US11722554 is a continuation of U.S. patent application Ser. No. 17/109,883. The Google Patents page for US11722554 also lists several "Priority Applications" and "Applications Claiming Priority," all stemming from the December 2, 2020, priority date. These include:

US17/819,442 (which is US11722554B2 itself).
US18/341,134, which led to US12381939B2.
US18/478,534, which led to US11985185B2.
US18/479,573, which led to US12273412B2.
US18/887,753, which led to US12192270B1.
US18/888,981, which led to US12255948B2.
US19/047,259, which led to US20250358330A1.

Additionally, US17/109,883 led to US11431786B1. This demonstrates a robust patent family built around the initial December 2, 2020, priority date.

Projected Expiration Date

The term of a U.S. utility patent generally expires 20 years from the earliest filing date of the patent application, or the earliest filing date of a parent application to which it claims priority. Any PTA would extend this term.

For US11722554, the priority date is December 2, 2020. Therefore, the anticipated expiration date, before any Patent Term Adjustments, would be December 2, 2040. The Google Patents page for US11722554 lists an "Anticipated expiration" date of 2040-12-02, which aligns with the 20-year term from the priority date. Without access to the specific PTA calculation from the USPTO for patent 11722554, it is not possible to provide a definitively adjusted expiration date.
