From reading this thread, as well as the announcement, I am left with the impression that the IP is only for the CADs that have been produced for his products. After all how could he claim IP on a specific class if that class has already been produced? (Class 92, APT, etc.)
Also, as has been pointed out elsewhere, how could he say that no one else can, for example, produce a class 92 in any scale when Brush was the actual builder and surely any IP for the class could possibly reside with them?
I think that there are numerous posters in this thread that are eager to condemn Mr Jones as they already have a negative opinion of him from previous issues, and while I don't think that is right they are entitled to their opinions.
Just my two cents, but of course I could be totally wrong.
