Every large company does this to some extent, because thre's a concept in US trademark law that if you don't aggressively and pre-emptively defend your mark then 'constructive abandonment' becomes a valid defense against infringement. That means people can rip off your trade mark and then say in court 'well, I thought he company had given up ownership of the trademark because they didn't sue 'monster plush toys', so I decided to call my energy drink 'Monster Brew.'' This is also why US companies slap a 'TM' next to every instance of their trademark, even though it becomes a visual distraction in graphic design terms. Lawyers will argue that if you don't aggressively police the bounds of your intellectual property at all times then it evaporates.
