Parrot, just intellectual property (9)
I believe the answer is:
copyright
'intellectual property' is the definition.
'parrot just' is the wordplay.
'parrot' becomes 'copy' (I've seen this in other clues).
'just' becomes 'right' (similar in meaning).
'copy'+'right'='COPYRIGHT'
(Other definitions for copyright that I've seen before include "Protection for writer" , "Document granting exclusive right to publish" , "property of the author?" , "Legal control of literary or artistic work" , "it gives one freedom to reproduce" .)
