If you do the research, the U.S. Leveraged a similar deal over the UK to obtain all patents royalty free as an incentive to enter WWII.
There may be some leverage that can be applied. These corporate and IP raids netted the U.S. hundreds of trillions of dollars.
I was first devastated when I first found this out. It reminded me that the line between the "goodies" and "baddies" was not so clear.
