Autodesk might want to settle this one

Autodesk has used DMCA 4 times before to pull auctions and did not complete the next step according to the law. The 5 time they did this, the vendor lost sales. Unless they took him to court over the 5 they are clearly guilty of using the DMCA to strong arm the guy and since ebay is involved as well, RICO could come into play with its every so interesting fines.
