Firestar Software has filed a patent claim against Red Hat for infringing on a patent Firestar filed in 2000 covering O/R mapping.

The complaint centers around Hibernate 3, and the patent claims that JBoss was given prior notice that marketing, distribution, and support services violates Firestars patent, and that Firestar “has suffered and will continue to suffer substantial damages.” Firestar produces the ObjectSpark, an transactional object mapping engine which appears to not have had a new release since May 2003, according to the Firestars press release page.
