Unreproducible chit Porgy composed (9)

I believe the answer is:

'unreproducible' is the definition.
(something under copyright cannot be reproduced)

'chit porgy composed' is the wordplay.
'composed' is an anagram indicator.
'chit'+'porgy'='chitporgy'
'chitporgy' anagrammed gives 'COPYRIGHT'.

(Other definitions for copyright that I've seen before include "Legal control of literary or artistic work" , "control publication" , "Document granting exclusive right to publish" , "Protection for writer" , "Sole entitlement to produce literary works" .)

I've seen this clue in The Times.
