The Federal Trade Commission and the antitrust division of the Department of Justice have asked the US Copyright Office (PDF) to exempt "commercial soft serve machines" from the anti-circumvention rules of Section 1201 of the Digital Millennium Copyright Act (DMCA). The governing bodies also submitted proprietary diagnostic kits, programmable logic controllers, and enterprise IT devices for DMCA exemptions.
