There is far more too it than has been made public, and all the

It appears that Sun is besting NetApp. Sun has gotten numerous NetApp
patent claims invalidated, including all claims for one of NetApp's
self described 'core' patents. Sun has also had a few of its patent
claims dismissed, but they have a larger arsenal which which they are
countersuing. If I were to put some skin in the game, I'd put money on
But what about Apple?
Apple needs a next generation file system, and they need it last year.
Or 2-3 years ago. Hence Apple's interest in ZFS. But the case is
already 2 years old and Sun is filing motions to stay the suit for
even longer, giving the US PTO office time to review and invalidate
even more patent claims. If Apple committed to and deployed ZFS, they
could easily be on the hook for many millions of dollars in licensing
fees down the road. It could end up costing them far more than
building a next generation FS for Mac OS X in house.
And what about FreeBSD?
