that Red Hat is being sued for patent infringement by a company called Software Tree. The patent
involved appears to be one of many covering the idea of an impedance-matching layer between an object-oriented system and a relational database. "Red Hat acquired open source developer JBoss in 2006 for $420 million. Software Tree contends that certain of Red Hat's JBoss products, including the JBoss Enterprise Application Platform, which includes JBoss Hibernate, step on its patent.
'The infringing products have no substantial noninfringing uses,' Software Tree says in court papers. The lawsuit also names Dell, Hewlett-Packard, and Genuitec as defendants because the companies sell JBoss-based software or include it on their products.
