Sun has sued Austin software firm Trilogy Software Inc. for patent infringement. According to this Austin Business Journal article:

Santa Clara, Calif.-based Sun Microsystems, the world’s fourth largest maker of server computers, sued business software maker Trilogy and its Versata and Nextance units for allegedly using its data-processing systems technology protected by patents awarded since 1998, according to papers filed Nov. 30 in federal court in Wilmington, Del.

In the complaint, Sun claims the defendants “are commonly owned” and “have acted in concert in connection with the infringement of Sun’s patents.” Sun seeks a jury trial, unspecified damages and an order to stop Trilogy’s use of the data-processing systems technology.
