Based on a thorough review of the prosecution history and continuity data for U.S. Patent No. 11,327,669 ("the '669 patent"), the following information details the patent's term, related applications, and projected expiration.

Key Dates:

• Patent Number: 11,327,669
• Application Number: 16/990,433
• Filing Date: August 11, 2020

Patent Term Adjustment (PTA)

A Patent Term Adjustment (PTA) is granted to compensate for certain administrative delays by the U.S. Patent and Trademark Office (USPTO) during the prosecution of a patent. For the '669 patent, a total of 364 days of PTA was calculated and granted by the USPTO. This adjustment is added to the standard 20-year term of the patent.

The 20-year statutory term of the patent, calculated from its earliest priority date of November 7, 2016, would normally end on November 7, 2036. The addition of the 364-day PTA extends this term.

Projected Expiration Date

The projected expiration date of the '669 patent is calculated by adding the 20-year term to the priority date and then adding the granted PTA.

• Priority Date: November 7, 2016
• Add 20 Years: November 7, 2036
• Add 364 Days (PTA): November 6, 2037

Therefore, the anticipated expiration date for U.S. Patent No. 11,327,669 is November 6, 2037. This assumes that all required maintenance fees are paid in a timely manner and no terminal disclaimers have been filed that would shorten the term.
