Foundation for a Free Information Infrastructure, has a press release declaring Sep 24 World Day Against Software Patents:
Brussels, 2nd September 2008 — A global coalition of more than 80 software companies, associations and developers has declared the 24th of September to be the “World Day Against Software Patents”. Five years ago, on 24 September 2003, the European Parliament adopted amendments to limit the scope of patent law and thereby protect small software companies from the harmful effects of broad and trivial software patents. A global petition asking to effectively stop software patents worldwide will be launched on 24 September 2008, together with specific additional requests for certain regions such as Europe, the United States or India.
