A YouTube video that is part of a Harvard University online course on copyright law is once again accessible to students after Sony Music Entertainment unblocked it and released its copyright claim.

As Corporate Counsel reported earlier, Sony had the lecture taken down from YouTube on the grounds of copyright infringement. The videotaped lecture, which explains aspects of copyright law as it applies to music and licensing, is taught by William Fisher, a noted copyright expert who is the WilmerHale Professor of Intellectual Property Law at Harvard Law School. The lecture includes clips of several versions of the Jimi Hendrix song “Little Wing,” which prompted Sony Music, which owns the rights, to have it removed.
