The intellectual property questions raised by the GNU General Public License (GPL) are under active discussion in PDF Solutions, where Sundar Dorai-Raj and I work. Sundar and I have recommended linking PDF commercial software to R. However, we have to be careful how we do this, because the GPL requires that the source for "all derivative works" be made public. Unfortunately, it seems unclear exactly what constitutes a "derivative work", although the GPL states that it does not apply to "independent and separate works ... when you distribute them as separate works."

Does anyone have information on this, beyond the groklaw and Forbes items already mentioned? For example, are there good examples to follow, or are all the published case studies negative like those already been mentioned?

It seems to me that a commercial company could comply with the GPL without jeopardizing its ability to pay employees and stockholders by distributing its software in two, separately installed pieces: The first would provide the base, commercial, proprietary software under a commercial license. The second would include all components distributed under the GPL license, and would add capabilities to the first. I think something like this would benefit both the R Foundation and commercial software distributors. However, our legal department has yet to rule on this, and our management is not eager to move without the blessing of our corporate legal. Therefore, more solid information, published case studies, etc., would help.

My $.02 (sorry, couldn't resist).

This is but one skirmish in the whole vexatious battle on "intellectual property
rights," which extends from software to many other venues, one of the most
interesting of which is patents on human genes. An example I heard on the radio
this morning was eHarmony.com patenting their algorithm for matchmaking, which,
the commentator said, is based on a 431 item questionnaire (yet another reason to
celebrate my long marriage; 431 questions -- yikes!) ! Needless to say, the
potential fodder for editorializing both for and against this intrusion of
"scientific method" into romance seems limitless. Do you think support vector
machines or neural nets lurk in the background of their "algorithm"?

Anyway, the only predictions that I think it safe to make are: (1) We have only
begun to fight -- and, yes, seeming samaritans (or is it samurai?) like R and GPL
may yet have to engage; (2) advances in technology will only turn the heat up and
pose yet more problems, as we move relentlessly from "thingy" inventions running
our world to 'idea-y" inventions running it.

Matchmaking, anyone?

(Thanks for your indulgence).

Cheers,
Bert

Actually, it was very recent. I pulled the electronic version of the
article from the Forbes website:


I would think twice before taking forbes articles too seriously. For
instance, they seem to think that protecting intellectual property
rights are all right when it's some big commercial company doing the
protecting, but not when they are on the other side of the table. See
this article from last year:
