As spotted by Gamereactor, the three patents each give detail on different skills Link can perform in the game, presumably by earning them like he did in Breath of the Wild.
The first patent describes the way that Link will be able to use a new rewind feature to manipulate the environment.
Rather than completely rewinding time in its entirety, as in a game like Prince of Persia: The Sands of Time, the patent shows Link rewinding a single object, moving it back to its previous location.

The second patent shows a new ability that would let Link travel upwards and pass through ceilings, phasing through them until he reaches the other side on top.
According to the patent image, the game would have to be satisfied that both the surface he passes through and the surface he comes out of aren’t too steep and don’t have any obstacles, and that there isn’t anything in the way as Link passes through.
Finally, the third patent details Link’s ability to free-fall, in which he’ll seemingly be able to move into various positions and fire at enemies as he does.
Nintendo is deliberately choosing not to reveal the proper title for The Legend of Zelda: Breath of the Wild 2 because it contains hints about the game’s plot.
The game will not actually be called Breath of the Wild 2 but will instead have a proper subtitle, like every other Zelda game. But Nintendo is deliberately choosing not to announce the name yet.
The game will feature an expanded world that includes the skies above Hyrule.
