Notch (the guy who started Minecraft) has a really good piece on why patents are a bad idea.
Why haven’t you signed this petition?
The court seems to be trying to not rule against all software patents while acknowledging they are broken and need to be reformed.
What’s interesting about this story is the suspicion that Google and Apple had not previously filed re-examination requests because their agreements with Lodsys prevented such an action, apparently not so at least for Google.
That point is the reason patents are a blight on the software industry, you can’t just stop being a part of the system. Patents are a field of hidden landmines for any person/company that does software of any sort.
