 Generally such lawsuits have been unsuccessful, chiefly because the functional design of the basic brick is considered a matter of patent rather than trademark law, and all relevant Lego patents have expired.On November 17, 2005, the Supreme Court of Canada upheld Mega Bloks' right to continue selling the product in Canada.A similar decision was reached by the European Union's Court of First Instance on November 12, 2008 when it upheld an EU trademark agency decision following an objection by Mega Bloks against a trademark awarded to Lego in 1999.
