Patent Term Adjustment (PTA)

The standard 20-year term for US Patent 8250357 would typically be calculated from its non-provisional filing date of September 13, 2001. This would result in a base expiration date of September 13, 2021. However, the stated expiration date is December 23, 2028. This difference of approximately 7 years, 3 months, and 10 days indicates a significant Patent Term Adjustment, granted to compensate for delays incurred during the patent's prosecution at the USPTO. Patent Term Adjustment aims to ensure that inventors are not penalized for unreasonable delays by the USPTO, as outlined in 35 U.S.C. § 154(b).

There is no indication of Patent Term Extension (PTE) for US Patent 8250357.
