Nintendo Switch 2 Controller Patent Points to Sequel for Million-Selling Game, Fans Believe

A fresh patent for a new Nintendo game controller has set tongues wagging that a Ring Fit Adventure sequel is on the way for Switch 2.

The patent, dug up by the appropriately-named Nintendo Patents Watch, was filed at the end of May 2025 and published online publicly this week — albeit with all of its images currently redacted.

Nintendo is named as the owner of the patent, which is listed as being for “video game controllers (accessories).” Most importantly, Nintendo employee Fumiyoshi Suetake is mentioned as the controller’s specific designer.

Suetake was a key figure in the development of the original Ring Fit Adventure, which launched in 2019 for Nintendo Switch and has now sold more than 15 million copies. The game is packaged with a pilates ring-style accessory, which players squash and stretch while exercising.

The appearance of Suetake’s name on the patent is a big clue that the currently unannounced controller may be a new Ring Fit accessory.

Additionally, Nintendo Patents Watch pointed out that Nintendo recently extended the patent on its original Ring Fit Adventure controller, suggesting the company still wanted ongoing legal protection for a product that was already available.

And finally, manufacturing giant Foxconn, a long-time Nintendo partner, has previously noted it is helping to develop new “force sensing technology” for a gaming firm, and has published a diagram showing what looks to be an updated Ring Fit controller.
