Apparent copyright (6)
I believe the answer is:
patent
I believe this is a double definition.
'apparent' is the first definition.
(I know that apparent can be written as patent)
'copyright' is the second definition.
(I've seen this before)
(Other definitions for patent that I've seen before include "Licence for inventors; obvious" , "Obvious, unconcealed" , "licence inside" , "Registration of invention or trade-name" , "Obvious - property right to invention" .)
