Q: Loophole to extend US provisional patient by 18-month by filing PCT and preserve original US priority date
I have filed a provisional US patent 11+ months ago (I have about a week remaining to file full patent). I know in the US there is no way to extend this without loosing my priority date of May 2020. However, can I refile this as a PCT, claiming the May2020 priority date, and then file the full patent in the US within the next 18-month and still have the May 2020 priority date in the US? Is this a valid loophole, which I can do if I pay ~$4000 fees for filing internationally?
A: This works, if international filing is important. However, there are better alternatives.
If the PCT is just a loophole and it has no value to you, a less expensive alternative would be to file a non-provisional application claiming priority to the provisional, optionally with a request for non-publication, and then abandon the non-provisional application at a later time in favor of a continuation or continuation-in-part application.
