Hasbro, Inc. v. RJ Softwares et al. was filed July 24, 2008 in the New York Southern District Court. This case relates to an allegation of trade-mark and copyright law infringement against the makers of the Facebook application Scrabulous.
The effect is that the well used Facebook application Scrabulous is shut down. I'm not a big user of Facebook or the application, but the New York Times reports that fans of the application are upset. Unfortunately, Hasbro's version of the game was having downloading difficulties. Electronic Arts develops the application for Hasbro.
