Thank you for your service. Super cool project. Hopefully they make their way to archive.org or Github someday.
(Based on 30 seconds of googling, it seems that the USA and Australia gives inventors a 1 year grace period after publishing, but the granted patent might not be valid in other countries.)
Not sure if it got better or worse with WTO patent rules.
The patent then serves as temporary moat on applying that specific technique or producing that specific device to refund the inventor.
In practice... well, sometimes patents were used to recover details of closed-source software or hardware.
