Patent Term and Expiration

• Patent Term Adjustment (PTA): A review of the prosecution history for US Patent 11,431,431 indicates that there has been no Patent Term Adjustment granted by the USPTO. The application did not experience 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 this patent is eligible for or has received any Patent Term Extension under 35 U.S.C. § 156, which typically applies to patents covering products that undergo a lengthy pre-market regulatory review (e.g., by the FDA).

• Projected Expiration Date: The patent was granted from an application (US 17/355,469) filed on June 23, 2021. This application claims priority to an earlier non-provisional application filed on January 27, 2015. Under 35 U.S.C. § 154, the term of a US patent is 20 years from the filing date of the earliest U.S. non-provisional application to which priority is claimed.

  Therefore, the projected expiration date is January 27, 2035. This date is contingent on the timely payment of all required maintenance fees.
