- Is it really necessary to reverse-engineer the VCR+ algorithm? I thought
- that VCR+ is patented. If you can obtain the patent number, then the patent
- can be retrieved. The patent _must_ disclose the method used.
-
- Of course, you can't legally _use_ the patented technology without licensing
- it, but it's perfectly legal to understand the technology. That's the whole
- point of the patent system -- to make information public.
-
- I guess the question is whether the patent number is public information...
