you guys are funny. If you have trademarked your name you can submit to google claim and block all ads that use your trademark as a part of ad content. You cannot prevent anybody in USA to bid on your trademark name.
You cannot forbid me to talk about you, it is freedom of speech, and I can put page about your business on my website and give my opinion and if google finds it the most relevant, comprehensive and interesting/unique article on the web about your business then you have a problem and me #1 position.
