Just ran into a generic 2 word phrase used in my US targeted ad copy that AdWords says is disallowed due to trademark issues.
Turns out no one has a TM on this according to USPTO, (it may be too general a descriptive phrase) and there appear to be no sites using a TM or R on this phrase that I can find.
One company does use it in their URL, but they are outside of our area and also make no R or TM claim on their pages.
Plus, when I go into "contest" the phrase, the interface does not indicate that the contestation has been logged, and the interface gives me little confidence that they even care about the contestation.
When talking trademarks, remember that you must abide by trademark laws for each country that you've set your campaign targeting to.
This means that if you have a campaign set to both the US and UK; the ad copy and keywords in that campaign must abide by the trademark laws of both countries.
There are times Google makes a mistake and you can ask for an exception as well.
We may at some point want to use it internationally, but at the first look, I just don't understand how they could call it limited by trademark, as there is nothing in the USPTO. Is there some other authority they are using that is more comprehensive than USPTO?
-- by the way, in follow up, a call to Google customer service did resolve the situation quite nicely - so the answer to my question has been resolved.
