Patent Term Adjustment (PTA) was established by the American Inventors Protection Act of 1999 and provides for day-for-day adjustment of patent term (i.e., the period of time a patent is in force) for certain USPTO administrative delays (“the 14-4-4-4-36 timeframes”) for certain patent applications. The specified timeframes are to: issue an Office Action within 14 months after application filing, respond to a reply or appeal within four months, act on the application within four months after a decision from the Patent Trial and Appeal Board (PTAB) or from a Federal court, and issue the patent within four months after payment of the issue fee. Additionally, a 36-month timeframe applies if the USPTO does not issue a patent within three years of the filing date or national stage commencement, with certain exceptions. Further, time consumed by interference or derivation proceedings, delays caused by placing the application under a secrecy order under 35 U.S.C. 181, or time consumed by a successful appellate review may result in positive patent term adjustment (PTA). Any positive PTA is offset by any period that an applicant failed to engage in reasonable efforts to conclude prosecution. This measure reports the PTA for all mailed actions.
