Patent Litigations as a Barrier to Innovation:
The Case of LEDs
Authors:
Cédric Gossart Altay Özaygen Müge Özman
Research aims
Do patent litigations deter innovations in Light Emitting Diodes?
Are there structural differences between litigated and non- litigated patents in the LED sector?

Litigation data: MAXWAL litigation databases
Discriminant function analysis: performed for 1990-2000 and 2000-2010.
Results
Litigated patents are significantly different in terms of their scientific basis, and their potential use in later innovations.
Litigated LED patents are highly scientific (i.e. they cite many scientific publications) => good quality => hard to invalidate => more law suits for infringement => barrier for SMEs & high costs (=> less money for innovation).
