PTA Calculation

Patent term adjustment (PTA) is a process carried out by the United States Patent and Trademark Office (USPTO) for adding day-for-day credits to the normal twenty year term from filing of a patent application based on delays in prosecution at the USPTO. Any USPTO delays occurring during prosecution of an application are offset by delays caused by applicants.

Yes, the USPTO has improved its accuracy since last year, but we still find ways to assist attorneys in law firms and our Fortune 500 clients alike find material errors. We find a systematic review surfaces significant errors which may impact tens to hundreds of thousands of dollars by affecting the term of the patent.

    A delay = PTO delay
    B delay = Pendency after 3 years
    C delay = Delay due to interference, appeal, secrecy orders
    O = Any PTO delay made after the start of B-delay
    P delay = Applicant’s failure to engage in reasonable efforts to conclude the examination
