Nintendo has grabbed another trademark for use in Japan. This time around they've secured a trademark for the name Pilotwings. This trademark applies to just video games, but no details on what it will be used for were shared.
Why do I have a funny feeling that if they *were* to use Switch's VR mode, it would be with this?
Chances are it means nothing. Nintendo renew trademarks all the time and most times nothing ever comes of them. Today, they also renewed a couple of trademarks for the Gamecube controller and another Smash Bros Brawl. It's just something they periodically have to do or they'll lose the rights to the items/games.
