Keine "Software-Patente" in Europa
Wir protestieren gegen "Software-Patente" in Europa. 

Die EU-Kommission und der Ministerrat bemühen sich im Verborgenen um 
unbegrenzte Patentierbarkeit von Software, wie von internationalen 
Großkonzernen und Patentanwälten gefordert. Sie ignorieren dabei die 
demokratische Entscheidung des Europa-Parlamentes vom 24. September 2003, 
welche die Unterstützung von mehr als 300.000 Bürgern, 2.000.000 Kleinen & 
mittelständischen Firmen und Dutzenden von Ökonomen und Wissenschaftlern 
genießt. 

Darüber hinaus können Sie uns unterstützen, indem Sie den Aufruf zum Handeln 
II des FFII e.V. unterzeichnen.

Vielen Dank,
