The easy to use do-it-yourself tool that helps you easily calculate the patent's PTA and compares it to the USPTO calculation.
Patent term adjustment (PTA) is a process carried out by the United States Patent and Trademark Office (USPTO) that awards day-for-day credits to the normal patent term based on delays in prosecution at the USPTO. Any USPTO delay that occurs during prosecution of an application is offset by delays caused by applicants.
The default term of a typical patent is twenty years, counted from the earliest priority date of the patent application. Congress realized that the patent prosecution process can be rather lengthy, which eats into the patent’s lifespan, and so provided PTA to increase the life of certain patents. PTA is intended to compensate for USPTO delays in patent prosecution.
The best strategy to maximize PTA is to reduce application delay to the extent possible. We discuss here some ways to minimize patent term delays and costs.
For the national stage of a PCT application, the 14 month A-delay and the B-delay are calculated based on the date of commencement of the nation stage. The date of commencement for national stage applications is the earlier of:
