I`ve taken on several advertisers who were using my business name as the heading of their google PPC ad. The ads were always for juice or vitamin companies but said SCRAPBIZ at the top. ScrapBiz is a registered trademark.
They all immediately stopped but several claimed they were only using key words that were suggested to them.
It irritates the heck out of me that I have to monitor my business name to that extent. I also hate that my business gets linked through fake websites about MLM companies. I am not an MLM and I don`t care to be on these sites but you can`t seem to get yourself removed once you land there.
Kim - Fill out the form at https://services.google.com/inquiry/aw_tmcomplaint , and when you get to the section titled "Scope of Complaint - Advertisers Involved", check off "Your complaint involves all advertisers". Google will then prevent anyone from using your keyword in their ad text, whether entered by them, or automatically through keyword insertion. You`ll still have to monitor your trademark yourself, as advertisers can submit appeals to the automatic protection (i.e. trademark is designated 2(f) with generic usage), but this will pretty much prevent anyone from using your trademark.
