Lots of new information posted Dec. 1 on the Desire2Learn Patent Info blog . Suffice it to say that they are seeking relief from the USPTO to re-examine the validity of the patent, and they have petitioned the Texas court for a stay of proceedings while the re-examination is being considered. Read their post for more information. D2L had to pay $8,800 to ask the USPTO to examine itself to determine whether they are a bunch of idiots. Good luck with that. There are at least 8 prior art claims made by D2L in this request, including the oldies but goodies, Topclass and ClassNet. Even more fun is their reference to WebCT as prior art. They list six publications about WebCT that illustrate prior art where each of the publications came more than a year before the Blackboard patent filing (pages 37 & 38 of the USPTO request, linked in the D2L Patent blog).
