First, apologies if this question has already been answered!  Anyway,
here goes...

Originally, PB was licensed under Apache 2.0.  Later, the license was
changed to BSD to make it more compatible with GPL2.  On the FAQ there
is the following statement:

"Does Google have any patents on Protocol Buffers?

Google currently has no issued patents on Protocol Buffers, and we are
happy to address any concerns around Protocol Buffers and patents that
people may have."

Now the advantage of the Apache license is that it includes a specific
statement about the licensing of patents instantiated in the code,
which is not present in the BSD license.

What is Google's policy on this now the license has changed please?
