Lucid summary of Blackboard's defence of its patent

Updated 31/5/2008

Writing in THE Journal, Dave Nagel provides a lucid summary of Blackboard's response to the US Patent Office's rejection of US Patent 6988138. For me the striking feature of Blackboard's response was its use of excerpts - including sections of witness testimony - from the recent patent infringement court case. Desire2Learn has 30 days to counter. From what I can make of it, the Software Freedom Law Centre, whose ex parte invalidity claim was merged with Desrie2Learn's inter partes claim, is precluded from involvement. 31/5/2008. Things are now moving quite fast in the dispute between Blackboard and Desire2Learn, with each company jockeying for position, in Blackboard's case from a position of apparent strength. Michael Feldstein has extensive coverage.
