Nintendo has applied two trademarks with the copyright office in Japan this week.

According to trademark filings, Dr. Mario World has been registered as a trademark for downloadable content for smart devices. This should be no surprise as Dr. Mario World was announced as a free-to-play smartphone title made in collaboration with LINE.

The other trademark registered was Dr. Mario. The purpose of this trademark is for entertainment such as events, raffles, tournaments, and more.
