The U.S. Copyright Office recently announced that it is soliciting comments on proposed exemptions in rulemaking on exemption from prohibition on circumvention of technological measures that control access to works. In its announcement (first link below), "[i]n its triennial rulemaking proceeding regarding possible exemption by the Librarian of Congress of certain classes of works from the prohibition against circumvention of technological measures that control access to copyrighted works, the Copyright Office has received 19 proposals for classes of works to be subject to exemptions." A notice has been published to announce the proposed exemptions and seeks comments, with the purpose of the rulemaking proceeding being "to determine whether there are particular classes of works as to which users are, or are likely to be, adversely affected in their ability to make noninfringing uses due to the prohibition on circumvention." The formal notice of proposed rulemaking was published in the December 29, 2008 Federal Register (excerpt link below). Comments may be submitted through February 2, 2009.
