On August 17, my lawyer sent a final cease and desist letter to google - by email and by registered mail. The answer came from google by email on the same day. You can tell that it's either a standard response or just no one really bothered with it. You get the feeling that they don't care if they get sued.
Here is the answer from google:
Hello,

I was firmly expecting such a nonsensical answer again. However, a cease and desist letter was necessary to go to court.
