IP Holdings, LLC less than three weeks before trial, in a case that had been pending in the District of Delaware for nearly three and one-half years.

This suit is believed to be the first patent infringement suit involving open-source software. Red Hat recently settled this suit and another recently-filed suit with the same plaintiff. The settlement was structured to be compatible with all versions of the GPL (General Public License), the open-source license under which many Red Hat products are developed and distributed, and provides licenses to the patents for all of Red Hat's products. In addition, the license extends not only to Red Hat and its customers, but also to members of the open-source community who contribute to the development of Red Hat's products.
