Extensions

The USPTO does not calculate expiration dates for patents; however, they do provide resources to help estimate them, such as a downloadable patent term calculator. The term of a U.S. utility patent generally extends 20 years from its priority filing date. For applications filed on or after June 8, 1995, the expiration date is 20 years from the earliest filing date of the patent or the earliest related non-provisional application.

Based on the provided information for US patent 11516879:

• Filing Date: July 23, 2021
• Priority Date: September 7, 2016
• Publication Date: November 29, 2022

Given that the patent's filing date (July 23, 2021) is after June 8, 1995, its term would typically be 20 years from its earliest priority date. In this case, the earliest priority date is September 7, 2016.

Projected Expiration Date:
The anticipated expiration date, based on the priority date of September 7, 2016, is September 7, 2036. The patent abstract lists an "Anticipated expiration" of 2037-09-07, which appears to already account for an additional year due to patent term adjustment.

Patent Term Adjustments (PTA):
Patent Term Adjustment (PTA) can add time to a patent's term to compensate for delays caused by the USPTO during the prosecution of a utility or plant patent application. PTA applies to applications filed on or after May 29, 2000. The USPTO aims to meet certain statutory deadlines, including issuing a first office action within 14 months of filing, responding to replies or appeals within four months, acting on applications within four months of a PTAB or federal court decision, and issuing a patent within four months of the issue fee payment, or within 36 months from the filing date. Delays by the applicant can reduce any potential PTA. While the specific PTA calculation for US11516879 is not explicitly stated in the provided text, the "Anticipated expiration" date of 2037-09-07 (from the patent abstract) suggests that some adjustment has been applied to the nominal 20-year term from the priority date (September 7, 2016, which would yield a 2036 expiration).

Patent Term Extensions (PTE):
Patent Term Extension (PTE) is available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore time lost during premarket government approval from a regulatory agency. The provided patent (US11516879) relates to wireless communication, which typically does not fall under the categories eligible for PTE. Therefore, it is highly unlikely that this patent has received or would receive a PTE.
