From Wikipedia, the free encyclopedia
The Tetris Company LLC, aka TTC, is based in Hawaii and is managed by Henk Rogers. The company currently owns the trademark to the game Tetris, originally conceived by Alexey Pajitnov. Tetris is widely considered one of the most popular games ever released, which is reflected by its mobile edition being the top seller in the industry.[1] . The company licenses the Tetris trademark to video game development companies and maintains a set of guidelines that each licensed game must meet. [2]
TTC had a moment of fame in the late 90s when they tried to get every freeware and shareware version of Tetris off the market by sending out cease-and-desist letters. It's widely believed[citation needed] that the company has no valid legal basis to claim rights to any tetromino game that does not infringe on the Tetris name trademark, since copyright "look-and-feel" suits have not stood up in court in the past (Lotus v. Borland), and as of 2006, a search at the United States Patent and Trademark Office revealed no U.S. patents related to Tetris assigned to Elorg, TTC, or Tetris Holding.
