GROKLAW – On Standards
The LawBlog of GROKLAW has a good look at the law relating to standards. Specifically it looks at the SCO assertation that it owns something about the ELF format used by Linux along with other POSIX systems.
This is of interest since standards may be copyrightable, but the information inside them is not. Subtle point, but copyright only ever covers the expression of an idea, and not the idea itself. Patents are used for that reason.
