I revisited the 2007 letter sent by Alliacense to amazon. It references products from unlicensed suppliers and sold by amazon. It specifically references certain Matel toys. Also, Some of the unlicensed suppliers at that time included:
Hasbro
Matel
Leapfrog
Microsoft
Sorry, I could not copy and past the document in its entirety.
For anyone having an USITC account, you may find the letter as exhibit 7 to the original complaint filed with mutliple exhibits.
