Xfire, a popular game chat utility, has recently come under attack from Yahoo. Yahoo is suing Xfire for patent infringement, citing that the technology used in Xfire was previously patented by Brian Gottlieb and Chris Kirmse while under employment by Yahoo.[break="click to read the rest"]
Should the case continue, lawyers say a matter such as this could cost over $2 million to defend and take up to two years to resolve.
The patent, referred to as the '125 patent for the last three numbers of U.S. 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 employees when they're hired.Xfire issued an official response that simply states how they are disappointed in how this matter is being handled, and they thank their over one million users for their support.
In the case of the '125 patent, Gottlieb and Kirmse were employed by Yahoo when they developed technologies for a game-specific variation on Yahoo's popular Yahoo Messenger. Yahoo has been the sole owner of the '125 patent since it was granted.
