This seems too simple, but aren't pending patents available for public scrutiny as are patents granted. I'm probably wwrong on this but I seem to remember being told that this is so. If this is the case the question of how HDCD works is easily answered/dug up. Albert Chau kchau@sfu.ca

In the US, patents pending are confidential between the Patent Office and the inventor. If the patent is denied, the invention remains confidential. It is only disclosed if the patent is granted. This is not true in some other countries, where the invention becomes public whether the patent is granted or denied. --PSW
