Delays happen during prosecution. Everyone knows that, including the United States Patent and Trademark Office. Which is why the USPTO will credit an applicant for the patent term lost due to USPTO delays. Whether caused by the examiner or applicant, our Patent Term Adjustment (PTA) review systematically calculates all prosecution events to determine the correct PTA.
We provide a detailed report comparing our timeline to the USPTO’s official calculation. For biopharma patents, in particular, the difference can mean tens of millions of dollars in continuing revenue.
