Xfire Countersues Yahoo!
Yahoo! filed a lawsuit against Xfire for patent infringement and is asking for money damages and jury trial. Xfire has filed a countersuit against Yahoo. Brooke Hammerling, Vice President of Media Relations saysT that in late January, Yahoo sued Xfire, the fastest growing online gaming platform and community, for patent infringement. As a result, Xfire tried to contact them and prove that its service did not infringe on Patent Number 125.
"As Yahoo has not responded to repeated efforts to get in touch and this lawsuit is an attempt to drive Xfire out of business", says Hammerlind.
The patent, referred to as the '125 patent for the last three numbers of US Patent No. 6,699,125, was granted to two then-Yahoo! employees Brian Gottlieb and Chris Kirmse on March 2, 2004. As is typical, ownership of inventions by employees remains with the corporation the employees work for. Such ownership rights are usually sealed in hiring contracts signed by the employee when he or she is first brought on.
In the case of the '125 patent, Gottlieb and Kirmse were employed by Yahoo! when they developed certain technologies for a game-specific variation on Yahoo!'s popular Yahoo! Messenger. Yahoo! has been the sole assignee--or owner--of the '125 patent since it was granted.
The complaint describes the Yahoo! Messenger instant message service--in this case, the GameProwler instant messenger application--as one that "allows users to use a game server in connection with a messenger server to permit 'buddies' to know when other 'buddies' are playing games online, and easily join such games."
Xfire offers a client application that allows gamers to chat with other gamers online. It also serves to help quickly facilitate gameplay on remote servers.
"Like the Yahoo! invention," the Yahoo! complaint reads, "this capability allows a user to see other users identified as 'friends' or 'buddies' designated on the user's computer in an instant messenger window. Also, like the Yahoo! invention, this product allows a user to see if a 'friend' or 'buddy' is online with her instant messenger program activated and also to see whether that 'friend' or 'buddy' is playing a game online...
"Defendant has no license or permission from Yahoo! to offer this capability."
The Xfire client was first made available in beta form last year. Xfire recently promoted the fact that it had reached the 1-million-registered-user threshold.
Yahoo!'s GameProwler appears to be the application it feels was compromised by the XFire client.
Key to the complaint is Chris Kirmse, now Xfire's vice president of engineering. Yahoo! claims that "after Kirmse joined defendant [Xfire], defendant began to develop, test, and offer instant messenger 'client' software and a messenger server that, when operated with game servers, offers the capabilities of the invention."
Kirmse joined Xfire in August 2003. He had left the employ of Yahoo! some years earlier, according to sources.
