The patent re-examination has been filed and things are starting to happen. Here are some URLs:
THE SFLC Release
The Sakai FAQ
Educause Letter to BlackBoard (Scroll to the bottom)

I don’t have much else to say beyond the FAQ and the press release. I am glad to be moving forward. The patent clearly was pretty poor.
Before the filing, I write a few posts about patents that allowed me to comment in an allegorical style without revealing what was being discussed or the strategy/approach being used by the SFLC.
These are from my earlier blog:

The implication is that a proper patent when filed goes to some length to find prior art.
I also wrote a blog post about the notion of software patents in general using the Boyer-Moore search as an example of how an idea should not be patented and how patents can be filed around an idea without patenting an idea.

This was not as strong but is an interesting take on things.
