InsaneGeek writes: NetApp is suing Sun over it's use of patented algorithms used in ZFS. Sun originally claimed NetApp infringed upon their patents after investigating Sun's claims and believing they are without merit, NetApp is striking back with ZFS being the target. NetApp has requested a court injuction against their patented implementation continued distribution in open or closed source form. According to CNET News NetApp will not use the courts to go after any educational, research or non-competing users of the technology. What kind of wrinkles does this put into Apple's plan of having ZFS included in Mac OS X Leopard, and the obvious competing FreeNas project's plans to use ZFS upon release of FreeBSD 7.0, etc.
