According to the wikipedia page, the last Lego patent expired in 1989. There may have been some design patents that expired more recently perhaps (assuming wikipedia is correct) ?
My experience of the Lego knockoff products has been that they use inferior plastic that isn't quite as stiff as the Lego formulation and they don't get the internal moulding right either, so the parts don't lock together in quite the right way: they don't have that secure 'click together' feeling that Lego proper has.
