Google joins the BAN-wagon with Apple in removing Tetris-like games from its Android app store, according to Ars. The Tetris Company, which handles licensing for the popular franchise created by Alexei Pajitnov, has sent a DMCA takedown to Google, who in turn has eliminated all Teris-like games from its store.
35 Tetris-like games have been removed from the Android market - even though many of them didn't use any art or knock off names that might trick users into thinking the games were the "real deal."
Tetris Company's challenge to these games, according to ARS, is that they "infringe on the game's trade dress, which is protected under the Lanham Act" (see bitlaw.com for the actual law). Trade dress relates to the "likeness of a product" and deals with copy cat products that might be confused with the real product.
The official game created by EA sucks, says Ars. I'll take their word for it.
