Patent Term Adjustments

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.


Boolean IP assists law-firms, individual inventors and multinational companies and other increase revenues by adding days, weeks, or even months to the term of the patent. We believe that a systematic review surfaces significant errors which may impact tens to hundreds of thousands of dollars by affecting the term of the patent.

The Patent Term Adjustment is calculated independently of the PTO calculation using the file wrapper or data in your database. The PTA is calculated at the time of Allowance as well as Post-Issue. Petitions to correct the PTA are filed as requested when necessary.
