Patent Term Adjustment

Maximize the lifespan of your
most valuable assets

We Dig Into The Past To Extend Your Future

While you may have anxiously waited for your patent grant, we know you’re not in a hurry for its expiration. We have helped both law firms and corporations take advantage of the true lifespan of their patents. We add not only time, but can help add millions of dollars to your company’s revenue.

Delays happen during prosecution, which is why the USPTO credits an applicant for the patent term lost due to USPTO delays. Our Patent Term Adjustment (PTA) review systematically calculates all prosecution events to determine the correct PTA, and we’ll provide a detailed report comparing our timeline to the USPTO’s official calculation.

How is Patent Term Adjustment Calculated?

Patent Term Adjustment is calculated based on examiner and applicant delays during patent prosecution:

  1. PTA = A delay + B delay + C delay – Overlapping delays – Applicant Delays
  2. A delay = PTO delays in responding
  3. B delay = Pendency after 3 days
  4. C delay = Delay due to interference, appeal, secrecy orders
  5. Overlapping delays = Any overlap between A, B, or C delays
  6. Applicant delay = Applicant’s failure to engage in reasonable efforts to conclude examination
