Recalculating Patent Term Adjustments

View as PDF

We estimate that more than one-fourth of the US Patent and Trademark Office’s (USPTO) patent term adjustment (PTA) calculations may be wrong.

Errors can be procedural or substantive. The USPTO draws information from its database in order to calculate PTA. If such information is incorrect, then the PTA will likely be incorrect. Examples include miscoded or mislabeled documents and incorrect dates.
