Red Hat landed with JBoss patent suit

Red Hat has been hit by a patent lawsuit related to JBoss, just weeks after completing its purchase of the open source software company.

In a complaint filed in US District Court in Texas this week, FireStar Software claims JBoss' Hibernate 3.0 infringes on its patent for linking relational databases with object-oriented software. Hibernate is an object-relational mapping tool for Java that's an open licence product and part of the JBoss Enterprise Middleware System.

In a jury trial, FireStar is seeking treble damages (three times the amount awarded by the jury) and a halt to infringing activity, naming as defendants JBoss, Red Hat and DaVinci-Matterhorn, a wholly owned subsidiary of Red Hat.

A Red Hat representative said: "We're aware of the situation, and we're working through the proper legal channels to resolve it."

Linux distributor Red Hat announced its plan to acquire JBoss for $350m in April and completed the deal on 5 June. According to the complaint, FireStar sent a cease-and-desist letter to JBoss on 26 May, before the acquisition was completed, then sent another to Red Hat on 7 June.

Analysts are questioning why FireStar went after Red Hat in particular. The patent relates to a "method for interfacing an object oriented software application with a relational database to facilitate access to the relational database," according to the patent application itself. This technology could apply to any number of other companies just as easily, analysts said.

Anne Thomas Manes, a research director at the Burton Group, said: "Why aren't they going against Oracle? They have much deeper pockets. Why not Sun [Microsystems]? Sun's Java Persistence API is not identical to Hibernate but it's really close."

Neither FireStar nor its attorneys handling the case were available for comment.

Stephen Walli, vice president of open source development strategy at consultancy Optaros, said even if other companies don't formally join in Red Hat's defence against FireStar, they may choose to offer legal assistance in the background.

Walli said: "When you are dealing with open source issues with Red Hat, IBM, Oracle and Sun, you almost don't get to pick your target."

Both JBoss and Red Hat use the business model of charging for support and services of open source software, rather than levy licensing fees for use of proprietary technology.

Though all the companies involved in the suit are registered Delaware corporations, FireStar launched its suit in Texas. Current patent law standards allow a patent infringement lawsuit to be filed in any state where the patent was believed to be infringed on. FireStar filed its complaint in the Eastern District Court of Texas, a Federal District Court known for its expeditious processing of patent infringement cases.

Because the complaint requests a jury trial, Red Hat faces a drawn-out legal battle and a possible injunction, both of which could cost it a lot of money.
