The Software Freedom Law Center said Thursday that it has asked the U.S. Patent Office to re-examine a patent awarded to education software company Blackboard. It claims that the patent is bogus and could undermine three open-source education software projects it represents–Sakai, Moodle and ATutor. The patent, No. 6,988,138, is titled “Internet-based education support system and methods” and relates to a central feature of Blackboard’s software: The ability to grant different people, such as students and teachers, different access rights to online resources such as grades, files or quizzes.
“It’s a junk patent that should never have been given by the Patent Office,” said Richard Fontana, a patent attorney with the Software Freedom Law Center. And the patent’s claims could have an impact on the three projects, he said: “They do effectively cover just about any e-learning software that is currently in use.”
