Red Hat faces a patent infringement lawsuit over an application that came under its wing as a result of its acquisition of JBoss.
FireStar Software alleges that the Hibernate 3.0 software infringes on a patent issued in August 2000. The patent involves mapping between an object model and a relational database.
Hibernate 3.0, a persistence engine, is a component of the JBoss Enterprise Middleware System.
FireStar is seeking unspecified damages. The patent claim could potentially have an effect beyond Red Hat, says Florian Mueller, a leading activist against software patents.
