+The Structure Query Collection is released to the public domain.
+
+Andrew Dalke and Andrew Dalke Scientific AB dedicate any and all
+copyright interest in this code and data sets and any database right
+to the public domain. We make this dedication for the benefit of the
+public at large and to the detriment of our heirs and successors. We
+intend this dedication to be an overt act of relinquishment in
+perpetuity of all present and future rights to this code under
+copyright law.
+
+If this is not acceptable to you, your laywers, or your judicial
+system, then we grant you the right to apply the terms of the CC0 1.0
+Universal license waiver instead.
+
+
+Please note that portions of this collection may be covered under
+someone else's copyright or database right. The details depend on the
+data set and your judicial system. To the best of my current
+understanding:
+
+  The BindingDB data sets have no restrictions. The SMILES strings are
+  user-contributed via Marvin and too short and non-creative to be
+  covered under copyright. The SMILES are collected in the US, which
+  is not covered under the EU database right. The SMILES are extracted
+  from the log files, with no creativity into the selection or
+  arrangement, so under the Feist ruling, the data set is not subject
+  to copyright.
+
+  The Ehrlich and Rarey SMARTS come from the "Additional Files" data
+  sets. I can find no specific copyright claim to that data, but the
+  paper itself is under the CC Attribution License 2.0. The BioMed
+  Central journals policy is that these files are usually "Open Data",
+  with very permissive terms. (Too bad I can't find those terms.)
+  HOWEVER! The actual SMARTS patterns comes from other sources.  See
+  the README in that directory for details. While I believe that there
+  are no copyright or database right claims which prevent the use and
+  distribution of these SMARTS, I have not been verified that this
+  belief is true.
+
+  The RDKit SMARTS are released under RDKit's MIT/BSD-like
+  license. The authors of those SMARTS specifically intend for them to
+  be widely used.
