Rorschach test
On September 9, 2008, Hogrefe attempted to claim copyright over the Rorschach ink blots during filings of a complaint with the World Intellectual Property Organization against the Brazilian psychologist Ney Limonge. These complaints were denied. Further complaints were sent to two other websites that contained information similar to the Rorschach test in May 2009 by legal firm Schluep and Degen of Switzerland.
