<h1>Impact Litigation for Copyleft</h1>

<p>Pursuant to our <a href="/copyleft-compliance/principles.html">Principles of
  Community-Oriented GPL enforcement</a>, Software Freedom Conservancy
  (<abbr>SFC</abbr>) engages in
  litigation only as an last resort when other methods to adjudicate users'
  rights under copyleft fail.  However, when necessary, SFC engages in impact
  litigation in lawsuits around the world &mdash; both as a Plaintiff
  ourselves and by paying the legal fees of other Plaintiffs.</p>

<h2>Current Copyleft Litigation</h2>

Our current impact litigation against <a href="/vizio/">Vizio</a> is ongoing
to establish users' rights under the GPLv2 and LGPLv2.1.  Please
do <a href="/vizio/">read more about it</a> and <a href="/sustainer">donate

<h2>Past Copyleft Litigation</h2>

These past lawsuits are listed in reverse chronological order.

<h3 id="avm">Sebastian Steck's AVM Lawsuit</h3>

<p>This <acronym title="Software Freedom Conservancy">SFC</acronym>-funded user rights lawsuit was filed by Sebastian Steck in Berlin in 2023 and received a positive final decision from the court in June 2024 with AVM providing "the scripts used to control ... installation of the executable" for the LGPLv2.1 works in the AVM router that Steck purchased.  More details are available in our press release and informational page, which provides the source code that was received from AVM allowing users to modify and reinstall copylefted works into the router's flash memory:</p>

<h3 id="best-buy-et-al">Software Freedom Conservancy v. Best Buy, et al</h3>

<p>On 14 December 2009, <acronym title="Software Freedom Conservancy">SFC</acronym> filed a federal copyright
lawsuit against 14 defendants, including Best Buy, Samsung, Westinghouse, and
JVC.
The <a href="https://ia600207.us.archive.org/21/items/gov.uscourts.nysd.355978/gov.uscourts.nysd.355978.docket.html">docket
of that lawsuit is available (on archive.org)</a> and
the <a href="/docs/busybox-complaint-2009-12-14.pdf">original complaint is on
    our website</a>.</p>

<p>SFC settled with each defendant at different times, and the
  dismissals can be seen in the docket &mdash; the last occurring in
  September 2012.  Generally speaking, and pursuant to
  our <a href="/copyleft-compliance/principles.html">Principles of
  Community-Oriented GPL enforcement</a>, Conservancy never settles a lawsuit
  unless we believe that full compliance has been achieved (or will be
  achieved imminently) with the terms of <em>all</em> copyleft licenses
  on <em>all</em> software included in the devices at issue in any lawsuit
  that we've filed.</p>
