SEGA has re-registered yet another trademark for yet another Dreamcast game. This time, it's puzzler ChuChu Rocket.

On December 22, SEGA U.S. re-registered the ChuChu trademark — one of many DC titles to get their TMs renewed. According to game site Siliconera, this year SEGA has re-registered trademarks for following Dreamcast games: Sonic Shuffle, Cosmic Smash, Jet Grind Radio and Virtual-On Oratorio Tangram.

Sure, this might just be SEGA protecting these trademarks, or it might be SEGA working on updates of these titles. Who knows? SEGA does, that's who.
