+<p>To the best of our knowledge, LLVM does not infringe on any patents (we have
+   actually removed code from LLVM in the past that was found to infringe).
+   Having code in LLVM that infringes on patents would violate the one of the
+   goals of the project by making it hard or impossible to reuse the code for
+   arbitrary purposes.</p>
+   
+<p>When contributing code, we expect contributors to notify us of any potential
+   for patent-related trouble with their changes.  If you own the rights to a
+   patent and would like to contribute code to LLVM that relies on it, we
+   require that you sign an agreement that allows any other user of LLVM to
+   freely use your patent.  Please contact the <a 
+   href="mailto:llvm-oversight@cs.uiuc.edu">oversight group</a> for more
+   details.</p>
