Patent Term Adjustments (PTA) and Extensions (PTE)

• Patent Term Adjustment (PTA): A review of the patent's file history indicates there was no Patent Term Adjustment granted under 35 U.S.C. § 154(b). PTA is used to compensate for administrative delays by the U.S. Patent and Trademark Office (USPTO) during prosecution. The absence of any PTA suggests the patent was prosecuted and issued within the statutory timeframes set by the USPTO.
• Patent Term Extension (PTE): There is no evidence of a Patent Term Extension under 35 U.S.C. § 156. PTE is typically granted for patents covering products that undergo a lengthy pre-market regulatory review, such as pharmaceuticals, and is not applicable to the technology covered by the '051 patent.
