The Rise of Open Source Licensing
Mikko Välimäki
A Challenge to the Use of Intellectual Property
in the So ware Industry
Mikko Välimäki The Rise of Open Source Licensing
Op — from Linux to Firefox and MySQL database
— has changed so ware business as we knew it. New start-ups have
challenged industry heavyweights from Microso to Oracle with inno-
vative copyright licensing strategies and courageous anti-patent policies.
Almost every major so ware company has been forced to react to the
commodifi cation trend.
Drawing from detailed case studies, historical narrative and the ap-
plication of economic theory, this book shows how open source licensing
is used for strategic advantage. So ware developers enter open source to
distribute their work more effi ciently and increase innovation. So ware is
no longer property, they say. Interestingly, everything has worked despite
— rather than because of — ever-expanding intellectual property rights.
Is there a limit? In the United States, the headline cases by SCO against
Linux supporters and users opened the surface of intellectual property
infringement risks. In Europe, there is ongoing public debate about the
impact of so ware patents on open source. This book goes beyond fear and
doubt arguing that such legal risks are in the end just necessary but man-
ageable uncertainties, which always come with a new business model.
M V teaches technology law at the Helsinki University of
Technology. He has consulted extensively on open source licensing.

THE RISE OF OPEN SOURCE LICENSING
ACHALLENGE TO THE USE OF INTELLECTUAL PROPERTY IN THE
SOFTWARE INDUSTRY
III
FOREWORD
This book is the result of my PhD studies at the Helsinki University of
Technology. I started working towards a doctoral degree right after
graduation from the University of Helsinki in 1999. I was supposed to
write a thesis in law. Now I need to apologize my then-supervisors profes-
sor Niklas Bruun and docent Pekka Timonen not to complete the thesis at
the law faculty in four years as was once planned. What happened was
that I met my future academic mentor, professor Jukka Kemppinen, who
had just started his professorship at the Helsinki University of Technology.
He convinced me to change my plans and my university in the late 1999.
The actual theme of this thesis started to emerge during my year at UC
Berkeley from 2000 to 2001. At that time I was working with Olli Pitkänen
and we were supposed to study digital rights management. But I went on
and spotted open source. I was lucky to participate at some of the first
business and technology conferences ever that were arranged on the topic
in California. I concluded that this is the area I have the best knowledge of
and, besides, it doesn’t seem to be a fad that disappears in the next two
years. So why not write about it?
The main creative writing periods of this book were in October 2003 in
Berkeley libraries and cafes, and August 2004 in the Starbuckses of Santiago
de Chile. In addition, there were also those numerable nights when I com-
pleted separate articles, which form considerable subparts of this thesis. I fin-
ished the work by completing all the open and missing parts under the su-
pervision of professor Juha Laine.
Dissertation examiners professor Jukka Heikkilä and Dr. Ilkka Rahnasto
made a number of substantial comments to a draft version of this book. I
have taken most of them into account. Professor Thomas Riis from Copenha-
gen Business School kindly accepted the invitation to act as the academic op-
ponent.
My understanding of open source has greatly benefited from discussions
with those who practice software business. As the public interest in open
source has grown, I have found myself lecturing and consulting open source
licensing to different organization from Finnish software companies to Inter-
IV
American Development Bank. Special mention goes to Antti Halonen who
introduced me to MySQL before there was a company for that particular pro-
ject. Mårten Mickos, MySQL’s CEO since 2001, has also been of help by giv-
ing constructive feedback and kindly sharing his connections.
Another bunch of special thanks go to my research colleagues Ville Ok-
sanen and Herkko Hietanen. In addition to several co-authored research pa-
pers, the founding of Electronic Frontier Finland in 2001 has definitely sharp-
ened my argumentation and overall writing skills. Through the association, I
have had the opportunity to participate into the public policy discussion on
copyright and patents from the inside.
I want to also thank Olga ja Kaarle Oskari Laitisen Säätiö, Jenny and Antti
Wihuri Foundation, Helsingin Sanomain 100-vuotissäätiö, Soneran tutki-
mussäätiö, Ella and Georg Ehrnrooth foundation and the Research Founda-
tion of Helsinki University of Technology for their grants supporting my re-
search work when that support was most needed.
Finally, thanks to my family, friends and colleagues not especially men-
tioned. There are just too many people I’ve met at universities, conferences,
business meetings and bars all around the world who have given their sup-
port and contribution in one way or other to this project. It makes me no
sense to list you all.
