-<p>Contributions must not knowingly infringe on any patents. To the best of

- intent to keep it that way.</p>
+<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>
