Vision no patent goes over the 12 months, does the patent pending protection go away? Or what happens? Yes, so that's a great question. The provisional patent is temporary protection for exactly one year after you file. So if you file on January 12 2020, your provisional is good until January 12 2021. You have to file the non provisional before that one year time period or you've lost all rights to the idea. It's your app, you don't have any rights. So what can be done, you have to file a non provisional before the end of the year. If it goes 12 months in one day, you've waited too long.
