Wow! I had no idea they were so litigious. I make my own cables now, but at least I have a reason to tell people to avoid Monster Cable.
Funny, of all the things I was looking for there, I'm surprised they didn't sue Monster.com job search engine. That would seem like a nice deep-pocket target. Certainly more profitable than Monster Mini Golf
Edit:
I didn't find it at the USPTO site, but there were a few google links that mention suing Monster.com.
