However the patents expired, allowing the design concept to be copied by other companies. Hence Megabloks, and other similar products.
I don't now if LEGO sued Megabloks for anything.
Megabloks has been out ages so I am not sure when the patent expired. Lego did attempt to sue Megablok if I remember right, though it gone thrown out because it's just a brick and you can't copyright a brick.
That's pretty much what happened. LEGO has failed quite a few times to enforce their ownership of the brick, specifically the studs and tube interior construction.
The plot thickens when one realizes that the original LEGO brick (before stud and tube construction) is an unlicensed copy of the construction bricks made by Englishman Hillary Page of KiddiKraft. LEGO ordered a batch of samples, rounded the dimensions down to metrics and sold them with no license!

LEGO finally bought the patents to kiddiecraft bricks for a rediculusly low sum nearly 40 years later a few years before failing against TYCO and their "Superbricks". (LEGO won initially, but it was overturned.
Sorry to get all off topic, but I'm a nut for anything LEGO related, even the darker side of the story.
