In October 2011, Apple filed for an in-app purchase patent to help protect developers from a company called Lodsys. This is because Lodsys filed a patent lawsuit against Android and iOS developers for having in-app purchases in apps claiming that they have patents that cover that feature. Now Apple has been granted permission to intervene in Lodsys’ lawsuit against developers including Rovio, the maker of Angry Birds.
Today, finally, Apple?s motion was granted in part: ?Apple is permitted to intervene in this suit, but such intervention is limited to the issues of patent exhaustion and licensing.? ? Judge Rodney Gilstrap concluded that Apple was entitled to intervene, and in any event, a permissive intervention (one that the court can allow in its discretion) was also an option.
