Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) provides an extension to the patent term to compensate for administrative delays by the USPTO during the prosecution of a patent application. To be eligible, the USPTO must:

• Issue an office action within 14 months after the application filing.
• Respond to a reply or an appeal within four months after the reply was filed or the appeal was taken.
• Act on an application within four months after a decision by the Patent Trial and Appeal Board (PTAB) or a federal court.
• Issue a patent within four months after payment of an issue fee.
• Issue a patent within 36 months from the filing date of the application.

The term is extended one day for each day beyond these specified periods. However, any accrued PTA can be reduced if the applicant fails to engage in reasonable efforts to conclude prosecution.

PTE is only available for the first approval of an "active ingredient."
