I'm not sure, I only just saw the notice RightInbox provided on their blog. Boomerang provides an almost identical service with a few varying features.
It seems a little far fetched that there is a patent on the feature of email tracking. I can only presume it was how they delivered the product.
Hopefully we'll see them bounce back using another method.
