ESP Wiki is looking for moderators and active contributors!

ESP Wiki:About

Welcome to ESP Wiki! ESP Wiki was launched in February 2009 by End Software Patents as the main global source for campaigning against software patents. After a period of inactivity, it was relaunched in September 2021. Ciarán O'Riordan was the main admin and core contributor of the wiki. Panos Alevropoulos is the current admin.

Here you will find information related to ESP Wiki. Starting in September 2021, major changes will be documented here in an irregular fashion. You can also consult our roadmap, which is a brief list of ideas we are willing to implement to ESP Wiki in the future.

Note that this page concerns solely ESP Wiki. For more information on ESP, check our dedicated entry. For updates related to ESP in general, check our blog.

Content policies

ESP Wiki shares the same content policies as Wikipedia, except for one: its neutral point of view. As a campaign to change the law, published content must adhere to both a political tone and an academic verifiability.

Against software patents

Entries are written for the purpose of raising awareness of the injustice that software patents impose on society. Opinions to the contrary are allowed to be published as long as they are accompanied by corresponding criticism.


Material challenged or likely to be challenged, and all quotations, must be attributed to a reliable, published source. Verifiability means that people reading and editing ESP Wiki can check that information comes from a reliable source.

No original research

Entries may not contain any new analysis or synthesis of published material that serves to advance a position not clearly advanced by the sources.

Discrete position allowed

As an exception, entries may feature a separate section that criticizes an aforementioned opinion. This exception is derived from the first content policy.


Completed items are moved to project updates.

  • Create an interactive map showing the state of software patents worldwide.
  • Form a robust community that is divided into distinct teams for contributing and monitoring information on the wiki.
  • Update the content of core wiki pages, using reliable sources and the wiki's style guide.
  • Catalog major software patents using MediaWiki forms.
  • Allow multiple languages; pages in languages other than English will have to be reorganized.
