The Patent Term Adjustment (PTA) statute at issue is 35 USC 154(b)(2)(c), which provides for a deduction from any PTA award "equal to the period of time during which the applicant failed to engage in reasonable efforts to conclude prosecution of the application." The statute also expressly delegates to the USPTO the authority to "prescribe regulations establishing the circumstances that constitute a failure of an applicant to engage in reasonable efforts to conclude processing or examination of an application."
