A federal appeals court has found all 38 of Blackboard Inc.’s contested patent claims to be invalid in ongoing litigation between the D.C.-based education software company and its Canadian competitor, Desire2Learn Inc.
This is the second time in the course of the three-year lawsuit that courts have poked major holes in Blackboard’s patent.
“Blackboard is obviously disappointed with the Federal Circuit’s decision and will seek further judicial review,” said Matthew Small, chief business officer for Blackboard (NASDAQ:BBBB). “Meanwhile, claims 39-44 of the 138 patent remain valid and enforceable. These claims were not at issue in the appeal.”
