Jayant and Rajat Agarwalla, Indian creators of Scrabulous, a Facebook Scrabble knock-off with 2.3 million users, are about to get sued by Hasbro for copyright infringement. Even though the game is free (or precisely because the game is free), Hasbro must enforce its IP rights if it would like to keep them. The brothers admit that they began their work "without thinking through the legal aspect at the time," although they did send a letter to Hasbro that was never answered. EA has the rights to the electronic version of Scrabble, so I'm sure they are not too pleased either. Now, the lawyers are working on settling a deal.
You Can't Be, Scrabulous!
