a silly patent (even by design patent stds), but the complaint illustrates that this patent is a pretty small part of a [smallish] thicket of patents on the ribbon concept, as well corel pretty brazenly trying to capitalize on the Office UI (whether that is a legit claim or not is up for debate) back when MS was pushing it (and of course MS allegedly meeting with Corel to "resolve" it after finding out). personal opinion is that it may have been a compelling claim in 2007/2008, but now just gives you that slimy feeling again. another good fact (probably irrelevant) is that microsoft is now (and has been) encouraging people to use the ribbon metaphor (as far as i can tell).
