Implications of the Green Case There are two important implications of the Green Case for television producers. First, the idea embodied a proposal document is not copyright, words in the document are; but this would not protect the same idea expressed in different words. There is no point in writing "copyright' on the document, but in most circumstances it would be protected by the law of confidential see section 25.6). There may be some point, therefore, in writing confidential on the document. The second consideration to come out of the Green Case is the question that it raises about the validity of format rights. This is dealt with a more length in section 25.5
