Tetris has distanced itself from a White House browser game inspired by the iconic puzzler, warning that it takes copyright infringement “very seriously.”
Tetromino’s as a design implementation is not trademarked, but the concept and names are. The Tetris Company owns the rights to any use of Tetromono’s and Tetris in the gaming sector. Being said, the patents to such concepts have already expired, so unless they were using trademarks naming I think they are fully allowed to use it. I don’t know if the Tetris company has any legal standing here.
Isn’t Tetris effectively public domain except for things that are made for consoles specifically?
