Welcome to the End Software Patents Wiki! End Software Patents is a global initiative of the Free Software Foundation with one goal: the elimination of all software patents in the world.
ESP Wiki is a comprehensive tool for finding information about software patents with the aim of organizing a global campaign for their legislative blocking. It includes detailed arguments, campaign material, numerous resources, and extensive legal information.
ESP Wiki is an international collaborative effort fueled by volunteers. It is the best source available for campaigning against software patents. We currently have 680 pages. You can help us expand them and improve their quality.
ESP Wiki is a pool of information, not a statement of ESP's views or policies.
