Flagrant licence (6)
I believe the answer is:
patent
This clue is a double definition.
'flagrant' is the first definition.
(I've seen this before)
'licence' is the second definition.

(Other definitions for patent that I've seen before include "licence inside" , "glaring" , "Obvious - property right to invention" , "evident" , "Copyright" .)
