SCO–Linux disputes
open-in-new
<p>In a series of legal disputes between <a href="/facts/SCO_Group/uftSH8RP">SCO Group</a> and <a href="/facts/Linux/9FvCKSTq">Linux</a> vendors and users, SCO alleged that its license agreements with IBM meant that <a href="/facts/Source_code/o9J6Jv23">source code</a> IBM wrote and donated to be incorporated into Linux was added in violation of SCO's contractual rights. Members of the <a href="/facts/Linux_community/aLlvF4D4">Linux community</a> disagreed with SCO's claims; <a href="/facts/IBM/QszA7nwd">IBM</a>, <a href="/facts/Novell/lABGMT7U">Novell</a>, and <a href="/facts/Red_Hat/5rhmBLBa">Red Hat</a> filed claims against SCO. </p><p>On August 10, 2007, a federal <a href="/facts/District_court/X72k0MGH">district court</a> judge in <i>SCO v. Novell</i> ruled on <a href="/facts/Summary_judgment/59u3SFI3">summary judgment</a> that Novell, not the SCO Group, was the rightful owner of the copyrights covering the <a href="/facts/Unix/0pNL2seI">Unix</a> operating system. The court also ruled that "SCO is obligated to recognize Novell's waiver of SCO's claims against IBM and Sequent". After the ruling, Novell announced they had no interest in suing people over Unix and stated "We don't believe there is Unix in Linux". The final district <a href="/facts/Court_ruling/4enNk4ul">court ruling</a>, on November 20, 2008, affirmed the summary judgment, and added <a href="/facts/Interest/qfNEuKg0">interest payments</a> and a <a href="/facts/Constructive_trust/UFI8AXp9">constructive trust</a>. </p><p>On August 24, 2009, the <a href="/facts/U.S._Court_of_Appeals_for_the_Tenth_Circuit/llRnEUfX">U.S. Court of Appeals for the Tenth Circuit</a> partially reversed the district court judgment. The appeals court <a href="/facts/Remand_(court_procedure)/DhuNzC8m">remanded</a> back to trial on the issues of copyright ownership and Novell's contractual waiver rights. The court upheld the $2,547,817 award granted to Novell for the 2003 Sun agreement. </p><p>On March 30, 2010, following a jury trial, Novell, and not The SCO Group, was unanimously found to be the owner of the UNIX and UnixWare copyrights. The SCO Group, through bankruptcy trustee Edward Cahn, decided to continue the lawsuit against IBM for causing a decline in SCO revenues. </p><p>On March 1, 2016, SCO's lawsuit against IBM was dismissed with prejudice; SCO filed an appeal later that month. </p>
