Kudos to Red Hat for this. However, arguing that software patents are harmful for open source falls short of the mark. In the end, they are harmful to everyone. In the best case, they raise the cost of software development for everyone, open source or otherwise, including anyone who does in-house software development. In the worst case, they make the development of certain programs impossible for anyone.

I think Bill Gates called it right years ago, when he wrote that patents would bring the industry to a stillstand, but I don't agree with his "solution" to acquire as many patents as possible: doing so only buys the patent holders a bit of additional time, i.e. they will be amongst last to be paralyzed by them (which of course is not without merit). But the patent creep will eventually catch up with everyone, leaving us with a software industry that can't do anything useful without paying toll to the patent trolls who won't do anything.
