The Washington Post has some insight into students suing the Turnitin system.|
Apparently, Turnitin's violating their copyright on their own homework, and coming up with false positives.
According to the lawsuit, each of the students obtained a copyright registration for papers they submitted to Turnitin. The lawsuit filed against Turnitin's parent company, iParadigms LLC, seeks $150,000 for each of six papers written by the students.
One of the McLean High plaintiffs wrote a paper titled "What Lies Beyond the Horizon." It was submitted to Turnitin with instructions that it not be archived, but it was, the lawsuit says.
