Just because you can read the source doesn't mean it isn't copyrighted.

Right, but it doesn't mean it's copyrighted either.

[mistercow]

Yes, it does. In the US, all copyrightable creative works (which includes CSS files) are copyrighted by default as soon as they are created. The system is opt-out, not opt-in.

In fact, there's not even an opt-out. You can just create a permissive license. There is no authoritative way to release a work into Public Domain.

[klapinat0r]

Exactly. In the US.

[mistercow]

Hmm, you do have a point. It seems that Malaysian and Indian law are what we need to know here, since that's where the two parties are based.

[asto]

Indian copyright law is the same. Copyrightable works are copyrighted by default.

[mthoms]

Actually it does - Copyright protection is automatic.
