Patent Office Orders Re-Examination of Blackboard Patent
SFLC, provider of pro-bono legal services to protect and advance Free and Open Source Software, had filed the request in November on behalf of Sakai, Moodle, and ATutor, three open source educational software projects. 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.
A re-examination of this type usually takes one or two years to complete. Roughly 70% of re-examinations are successful in having a patent narrowed or completely revoked.
