Multiple PPA (provisional patent application) Submissions?
« on: March 08, 2017, 02:50:27 AM »
Could an individual submit a provisional patent application (PPA)  and then resubmit a similar PPA if they wanted to add or subtract detail to make it more marketable in the future?  I understand the first to file date would be moved back for the new filing, but wouldn't this give the inventor the option of a quick but less documented PPA and a more fully documented PPA with a later start date when more details are known.

If PPA's aren't actually read or searchable, what is to stop multiple PPA submission of a similar, or the same topic by the same inventor or group?

Yes you can file multiple PPAs and we do this all the time, especially when you are making changes or tweaks to your invention.  You can than file a non-provisional within 12 months of your first PPA and link it back to multiple PPAs, or, you can file the non-provisional and just have it link back to a single PPA as long as the full non-provisional is filed within 12 months.

(I made a slight modification to your post to define PPA as being provisional patent application to help new people who may be reading this post later.)
