Nintendo may bring Professor Layton and the Miracle Mask to the 3DS in North America.
Developer Level-5 has filed a trademark for the game in the US and may be saving an official announcement for E3, suggests Siliconera.
The same pattern of pre-E3 trademarks have previously occurred with Professor Layton and the Last Specter and Unwound Future.
Miracle Mask marks the fifth entry in the series. A sixth game is in development, along with Professor Layton vs. Ace Attorney, due out later this year in Japan.
