slashdot_commentator's Journal: Network Appliances sues Sun over patent infringments in ZFS

Network Appliances is suing Sun Microsystems, alleging that seven of its patents are unlawfully being used in ZFS, the filesystem used in Solaris 10 and OpenSolaris. Ironically, Sun may have shot itself in the foot. They initiated legal proceedings against NetApp 18 months ago, over related patents Sun believed NetApp was infringing. Dave Hitz, NetApp's founder and Exec VP lays out his case in a blog entry.
