Richard Siegel and Blanca Gudino, 39, were arrested on Wednesday after detectives found more than 2,800 LEGO boxes at Siegel's Long Beach, California, home.
You're diving into Intellectual Property law here, and there's lots of nuance beyond just registered trademarks.
You could likely be fine selling a round pastry filled with apples call "LEGOS". If there was a trademark for it at one time, and it has been abandoned, you might even be able to register the trademark yourself for your round pastries.
I seem to remember a legal decision that prevented them from doing so (a horse leaving the barn type situation), so I don't think its possible. Lego is hardcore about the "lego" trademark though:
I think they’re referencing the idiom “closing the barn door after the horse has bolted”, ie taking a measure after it’s too late to accomplish anything.
Exactly! Just like we eat a bowl of popcorns or a plate of rices or pastas with beefs or porks, maybe with a nice glass of wines, teas or milks. After that we can go to the beach to play in the sands or if it's winter we stay in and watch the snows.
