I don't think I have ever heard, or read the phrase, "The French are after me." You are going to have to do some digging to find out exactly what they have claim to, but they are a very old company. It is always possible that they are overstating their claim. It does happen. It should take you about 20 minutes to check it out. Just make sure, before you make any rash decisions based on our advice. IF it turns out that they are right, I wouldn't fight it, but I would make a stink about it, and issue press releases and all kind of stuff stating that "Christian Dior ruined my lively hood for no good reason". "If I'm going down, and it's not my fault, somebodies coming with me" , kind of attitude. Even if it's just bad press. May work to your advantage.
