Lego have won a case at the EU courts protecting their iconic lego figure shape.

Lego has faced a number of challenges in recent years hence the rise in competitor block sets like Canadian Mega Bloks, with a red brick not being a trademark, and the 'bumps' that allow lasting connections of bricks not being deemed an innovation by Lego.
Which may have been true as Lego took the idea themselves from a British toy manufacturer in the 1930s.
