The Antitrust Division stated its support for the 2015 patent policy revisions in a business review letter that it issued in January 2015, upon request from the IEEE SA. In the letter, the Antitrust Division said that the provisions would unambiguously produce net benefits for consumers with insignificant anticompetitive implications. At least one commentator has criticized the Antitrust Division's legal and economic analysis put forth in its business review letter of the revisions, claiming that the Antitrust Division exaggerated the patent policy's procompetitive benefits and wrongly dismissed as unlikely some of its potential anticompetitive costs.
