updating PPAs (provisional patent applications)


updating PPAs (provisional patent applications)
« on: May 30, 2023, 12:16:20 AM »
is it possible to update PPAs and how to do it, or does one need to refile for every update?

Also, how long do I have to pay for a PPA if I do not do it online immediately when filing PPA? How is the payment done the easiest outside of USA?

You cannot add new material to any patent application after it has been filed so you cannot update it.  You should file a new application.  We sometimes have 2-5 PPAs that we later merge together into a full non-provisional utility application. 

If you did not pay the fee you will get a letter from the patent office telling you how to make payment.  However, in this case it would be safest and easiest for you to file your application again as a new PPA and make sure you pay the fee online this new version.
