They try to bankrupt small shop owners and producers by sueing them until they can’t financially recover, even if those shop owners would be in the right. And at the same time they don’t sue Schwarz-Group (Lidl) for doing the same stuff as the smaller shops, because Schwarz Lawyers could easily counter them and win.

They also live with the constant fear, that someone will sue them to remove their trademark name, as it is too commonly used as a synonym to bricks. Thats why they even youtubers wrongly calling competitors products Lego.
