The US Patent and Trademark Office today ordered re-examination of the e-learning patent owned by Blackboard Inc. Once again, we have the Software Freedom Law Center to thank for filing the request. Their press release tells us this:
The Patent Office found that prior art cited in SFLC's request raises "a substantial new question of patentability" regarding all 44 claims of Blackboard's patent....
