One quick example, before people go all 'nuclear' on Samsung on here, perhaps I should remind you of this:
The trademarked clock owned by the Swiss Railway company that Apple
STOLE and put into iOS, it then released said iOS update with the trademarked clock to the public and that was the first time the Swiss Railway Company knew Apple had stolen it.
The Swiss Railway Company then approached Apple who then paid 21 million $ for it's use, most likely to save embarrassment of removing the trademarked clock design they stole and because Apple was threatened with legal action.
Just showing that Apple steals too.
