Also don't forget that after their patent(s) expired Lego tried to claim that their shape was part of their trademark. Sued the pants off of MegaBlocks for trademark infringement in Canada. Lego lost in Federal Court, lost in the Federal Court of Appeals, and finally lost in the Supreme Court, 7-0 on the doctrine of functionality (https://en.wikipedia.org/wiki/Kirkbi_AG_v_Ritvik_Holdings_Inc https://en.wikipedia.org/wiki/Kirkbi_AG_v_Ritvik_Holdings_In...). Seeing this history I'm even more disgusted by Lego than before. Even when they added the holes on underside I'm not sure that should have been seen as sufficiently innovative to be granted a patent. And any patents before... well... prior art and all that.
