Yeah, not sure but it looks as if they are only concerned about the name being too similar to Chatroulette (Chatroulette-clone.com) but I'm no lawyer. Moving your business to the new Random Video Chat (RVC) name and abandon the the Chatroulette Clone (CRC) name seems to be the cheapest way to avoid further legal problems. You guys even said it yourself, your product is no longer a chatroulette clone because it does soo much more than what chatroulette does. To compare the two is harder now more than ever, a year ago it would of been easy to see similarities, now not so much. BUT my biggest concern is how does this affect your customers and those who plan to use your product in the ways they wanted?
No way, but he point in that the infringement of intellectual property rights might be extended to the very concept of chatroulette, which does concern not only the name, but the whole idea. What is certain is that directly qualifying something as a clone of something else may entail the risk of legal actions at any moment. To change the name is cheap, and it is definetly the first step to take !
