You have to file a provisional patent before filing for a utility patent, as I think I remeber that correctly. When you do file for your utility patent you have a time limit to file for the international. Imternationals are time dependant on how much you want to spend and for how long you need or want it. I didn’t get it because it was thousands for so many months. You have to be ready with your product sales before you get your utility, if you want a international, then renew it and renew it, I believe this is correct.
