Nintendo has filed a patent for its N intendo switchch Lite with the Japanese patent office. The listing simply states that it is "an electronic computer capable of playing the game" as well as the names of two input creators, Yui Ehara and Junichiro Miyatake.
Only a handheld console was released back in September of last year, so it's exciting to see ownership being developed now. However, Nintendo is known for protecting its capabilities and protecting copyright as important.
