The Vello uses a folding fork similar to the one of the Tyrell Ive.
The front wheel must not be removed like on some Bike Friday, the Ahooga, Change Bike, Montague....
Now its bigger folded than the Brompton and slightly bigger folded than the Birdy.
About the who copied what, I would say that the Vello folding is close to the Tyrell folding.
As far as I know, Riese & Müller didn't copy anybody when introducing the first Birdy?
