Patent Filing FAQ
Can I make changes to my Provisional Patent Application, even though it's already filed?
The U.S. Patent & Trademark Office does not accept updates to a submission, so if you feel you want to update your filing, you would need to file a new provisional patent application.
You can also submit these updates in the actual patent filing itself, if you are planning to file a patent later. However, if you forgot to include a critical component of your invention, you’ll need a new provisional patent application to fully protect your invention.
By signing into your account and clicking on your provisional patent application, and choosing “Review Answers,” you will be able to see the answer to this and several other potential questions you may have after submitting your filing.
