Ben Sturmfels writes "Over 500 members of the Australian software industry have have signed an open letter urging their government to abolish software patents. Signatories include free software luminaries Andrew Tridgell and Jonathan Oxer. In 2008 the Australian government began a Review of Patentable Subject Matter. While we missed the 2009 public consultation period, we hope to influence the government's response to the Review, due in February 2011. The letter will be presented to Minister Kim Carr in early August."
