Coming at this from an "this is a real-life example of software patents being {good|bad}".
That said, we shouldn't generalize Fraunhofer's economics to the rest of the software industry. If it was just this kind of thing I would have zero problems with it. But we should be suspicious of software patents because the patent system implicitly rewards ideas that are broad (more things a patent touches, more $$$) and non-inventive (less work to come up with a patent, more $$$). Patents can be dangerous to human progress, and the patent system encourages patents that are. A broad patent could hold a whole industry hostage for 20 years, which is an eternity in technology. I sympathize more with folks who want to get rid of the whole thing for this reason.
Even some private individuals like me (I think the company was called Fluendo?)
(edit: not Stockhausen, thank you!)
It's rather disingenuous, the assumption with the structure of your question is "within the framework of 'patents can be good'".
