I have a sneaking suspicion about this..........
Most of us are sole practitioners, and have no chance of defending our images against this if they get it through.
However, I have a feeling that if some wiseacre lifts a still image from a DVD of a Hollywood movie ("No, Your Honour. I didn't know that was Tom Cruise. Never seen him in my life before.") then the might of a Hollywood studio's legal department will show this up for the rubbish that it is.
It needs a test case at the other end to get rid of it once and for all.
