+% GPL's Handling of Non-Copyright Systems
+% Bradley M. Kuhn
+% Tuesday 9 May 2017
+
+# Non-Copyright Systems
+
++ Patents, NDAs, & other agreements often impact software.
+
++ GPL is essentially a copyright license.
+     - so, how does GPL handle these systems?
+
++ As always, GPL has **conditional** permissions.
+     - some such conditions relate to these other legal regimes.
+
++ Compliance for these is much more legalistic than technical.
+
+
+# GPLv2§7
+
+<span class="fitonslide">
+<p>[GPLv2&sect;]7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+</p>
+</span>
+
+# GPLv3 Improvements
+
++ GPLv3 expands GPLv2&sect;7 into multiple sections.
+
++ Creates detailed rules.
+      - an improvement
+      - legal compliance analysis is less complicated.
+
+# Staffing Question
+
++ In complex environments, both lawyers &amp; developers should analyze
+  compliance obligations.
+
++ Simple environments (i.e., no actual proprietary components in product),
+  less expertise &amp; cross-disciplinary staff time needed.
