Re: A plague on both of them
SQL and C are international standards, so I don't think licensing them is possible even for the originators (IBM and AT&T respectively).
If the standards body doesn't have written evidence of a transfer of copyright or a license to use said copyright from the owners of the copyright, then the standards body had no business including copyrighted material in the standard, and is itself in violation of copyright, as is everyone who then followed that standard.
The thing is, prior to this stoush, no one thought you needed a copyright transfer or license to use or incorporate APIs into the standard in the first place. If Oracle wins, then they will all have been wrong and all of them will be exposed to copyright infringement claims from the original creators of the APIs (AT&T?).
