The bar for novel/non-obvious seems really low if this patent has been successfully defended.
Even worse is that Red simply ripped off JPEG2000 and got a patent on it.
The patent "system" has become a tool for exactly what it was supposed to prevent: the theft of people's work.
IP expiration dates are a "brain plasticity" parameter in society. Higher values mean lower rates of change, too low values mean too high rates of change. Twenty years is a sweet spot.
Now if a new patent is filed the patent office cannot ignore it as prior work. While the bar for machine generated patents is high. There is IMHO no reason why prior art cannot be machine generated and if something very similar can equally generated by a machine it becomes even more questionable if something is patentable at all.
