I'm aware that OpenJDK is released under the GPLv2, which has an
implicit patent grant. However I'm curious about the explicit patent
grant given by Oracle when an implementation passed the TCK test.
I'm aware that OpenJDK has passed the Community TCK tests (Which doesn't
have any field of use clauses). Does this mean that an explicit patent
grant is given to OpenJDK?
The grant is here: http://java.sun.com/javase/6/jdk-6u21-doc-license.txt
My concerns are with this paragraph:
5. Definitions. For the purposes of this Agreement: "Independent
Implementation" shall mean an implementation of the Specification that
neither derives from any of Sun's source code or binary code materials
nor, except with an appropriate and separate license from Sun, includes
any of Sun's source code or binary code materials
OpenJDK is obviously Sun's code, so I'm a little confused here. Does
this mean the patent grant doesn't apply? Or maybe the GPLv2 is the
"appropriate and separate license".
