Someone finally asks some sensible questions, about hijacking of the term "open".
I seem to remember the company behind either Monster Cables, or Monster energy drinks, going after anyone that used the word “monster,” even in casual context.
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.
