  • The more significant, immediate result is that the Court found the “Means for assigning a level of access to and control of each data file based on a user of the system’s predetermined role in a course,” a “means-plus-function” term, to be indefinite. See pages 16-17 of the Memorandum Opinion. Because that phrase is indefinite, all of Claim 1 is rendered invalid because of indefiniteness. Further, all dependent claims that rely on Claim 1 (in our case, Claims 2 through 35) are similarly invalid.

  Out of Blackboard's original 44 patent claims, 35 have now been invalidated by the patent office.
