Analysis of Patent Term for US 11,997,568

Date of Analysis: May 8, 2026

Based on the authoritative patent text and prosecution history for US Patent 11,997,568, the following is an analysis of its term, related applications, and projected expiration date.

Patent Term Adjustments (PTA) and Extensions (PTE):

• Patent Term Adjustment (PTA): A review of the patent's file history indicates that there have been no Patent Term Adjustments granted. The prosecution timeline did not encounter delays attributable to the USPTO that would warrant such an adjustment under 35 U.S.C. § 154(b).
• Patent Term Extension (PTE): There is no indication that a Patent Term Extension has been sought or granted for this patent. PTEs are typically associated with delays in regulatory review for products like pharmaceuticals and are not applicable in this case.

Related Applications:

• Continuation Application: US Patent 11,997,568 is the parent application for a continuing application, US 18/431,686, which was filed on February 2, 2024. This continuation application claims priority to the same 2022-01-19 provisional application as the '568 patent. As a continuation, it will likely have claims that are of a similar or narrower scope than the parent patent. The term of any patent issuing from this continuation application will be calculated from the filing date of the original '568 application.

• Divisional Applications: No divisional applications have been filed that claim priority to US Patent 11,997,568.

Projected Expiration Date:

For utility patents filed on or after June 8, 1995, the term is 20 years from the earliest effective non-provisional filing date.

• Filing Date: The application for US Patent 11,997,568 (US 17/844,488) was filed on June 20, 2022.
• Priority Date: The patent claims priority to a provisional application filed on January 19, 2022. However, the 20-year term is calculated from the non-provisional filing date.
• Calculation: Adding 20 years to the filing date of June 20, 2022, results in a projected expiration date of June 20, 2042.

This expiration date is contingent on the timely payment of all required maintenance fees to the USPTO. Failure to pay these fees at the 3.5, 7.5, and 11.5-year marks after issuance will result in the patent expiring prematurely.
