The automatic trademark blacklist in Google adwords is really idiotic even if the trademark is valid. I once tried making an ad for my Mac app, and I couldn't include the word "Mac" or "Mac OS" in the copy because they are trademarks.
I had literally the exact same issue. They said I had to get them paperwork from Apple's legal department, ignoring Apple trademark page saying it's okay to use the Mac trademark to sell a Mac app which I forwarded to them with an explanation.
My exact ad said "Try _____, a better way to _____ for Windows and Mac".
