Will not be affected by the order of application (all by yourself)
If it is a third party, the date of application shall prevail.
They are all their own patents, so you don't have to take the initiative to revoke them. You can apply for an extension announcement at most.
But be careful not to fail the application first and then pass it, then you will be miserable (I can beat you with your first application and apply for approval later)
But this is a bad move in the lawsuit, and it will consume your bullets at most.
Don't publicly authorize the patent before it is published, because it will become an "open technology" without "novelty"
