The trademarks were found by Nerd Leaks and the logos have now made their way around the internet.
Tomorrow's Nintendo Direct will be devoted to Pokemon in celebration of the franchise's 20th Anniversary.
Section nine of the trademark covers the usual CD ROM, cartridges and disc-based releases, but mobile is also covered in section nine. This could be one of the five smartphone games DeNA is developing with Nintendo - the first to be released is Miitomo and it's out next month.
We'll see if we can dig up more on this. If not, we'll have to wait until tomorrow. It kicks off at 7am PT/10am ET/3pm UK.
Thanks, Nintendo Everything.
