I've been working on something like that at
(It's still in the initial stages.)

I am aiming for a one-size-fits-all patent license that could be
made to be suitable for any field.  I welcome any feedback.

That's exactly the idea I want to promote.

You might want to subscribe to the Free Software Business list,
fsb-subscribe at, which has discussed this sort of thing before,
mostly from a software patent point of view, but most of the discussions
are applicable to patenting in general.  Archives are at  (Look far back in the archives.  You'll
find more discussion over 6 months ago than recently.)

You might also want to look at and the archives of
its mailing list.  (Participants in the Open PPC project aim to design
and build a free Power PC based motherboard.)  Hardware licensing
discussions on the openppc mailing list have tended to be more specific
to computer hardware, and not immediately applicable to your case above,
but they should still prove helpful.
