Apache 2.0 has a better patent clause - against hostile IP claims, so tax dispute is not terminate the OrioleDB license:
"If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed."
It also seems a lot less strict on what is being terminated.
On violation the Apache 2.0 license terminates the patent license. I might be mistaken, but that reads an awful lot like you're still allowed to use the software provided you do so in a way which doesn't violate the patent.
On the other hand, the OrioleDB license seems to terminate the entire license - so the way I read this it would include parts of the software which aren't covered under the patent itself.
MPLv2 has a stronger version of this (I also personally prefer it in general to Apache-2.0 if you can't stomach GPLv3).
