I'm in the camp that assumes a MIT/BSD license would also grant any
patent license to use the work that the author may control. This is
my assumption because those licenses don't specifically reference
copyright in the language. Although, perhaps the MIT/BSD licenses,
popular as they may be, should be deprecated by the OSI if they are
seen as a substantial risk.
While the CC0 may be a fantastic public domain dedication and backup
license that keeps its nose clean and focused only on copyright law,
it seems that the explicit denial of patent license is a show stopper
for it to be considered a solid open source approach.
Perhaps the outcome here could be not approval of CC0 -- but instead,
a CC00 or CIP0 public domain dedication that additionally includes
patent right abandonment as well? That, I think would be OSD compliant
and very happily deployed by software developers.
