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 the earliest priority date of a patent application based on delays in prosecution at the USPTO.
We assist attorneys in law firms and our Fortune 500 clients increase revenues by adding days, weeks, or even months to the term of the patent. 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.
MaxVal offers a systematic review of the USPTO’s PTA calculation, which often results in increased PTA.
