The toy companies Hasbro (who own the rights to Scrabble in the U.S. and Canada) and Mattel (who own the rights to Scrabble for everywhere else in the world) have asked Facebook to remove the “Scrabulous” application as it infringes on their copyright for the game.
Mathew Ingram has already said this but I’ll say it again: Mattel and Hasbro are making a mistake by giving in to the knee-jerk impulse to think “infringement!” and calling in the legal team. All that will do is generate ill will towards them. A far more profitable approach would be for them to simply buy the application from its creators — which they could easily do for a few hundred thousand dollars, mere pin money to them — and use it as a marketing tool for Scrabble as well as other games in their stable.
