Common sense required
How on earth can common expressions be "owned" by a company.
Winter is coming - its a standard expression used across the world and has been for a very long time. Perhaps I should get a film made where I use the word "Hello" a lot, then go and screw the world for trying to be make contact with other individuals.
So, lets try something :
Winter is coming
Christmas is coming
The new year is coming
Brexit is coming
See, all common expressions, none can be protected if we have freedom of speech.
Time for a reboot on the DMCA. What a bunch of complete idiots.
