Well, to pick one, here is the language from the Initial Developer's
patent grant in CDDL:

	No patent license is granted: (1) for code that You delete from
	Original Software, or (2) for infringements caused by: (i) the
	of the Original Software, or (ii) the combination of the
Original Software 
	with other software or devices.

So, for example, FT could open-source an audio codec under CDDL and have
a high degree of confidence that they have granted a license
*only* for patents which read on the Original Software and
*only* for CDDL-licensed applications.  Compare and contrast with
the blanket promise not to assert patents Licensor gives Licensee
in your current draft of CeCILL.

I'm not suggesting that the patent non-assertion clause of CeCILL
violates the OSD.  I am suggesting that when big company lawyers
read CeCILL in its current form, they will blacklist it.
