EU central court could validate software patents

protoshell writes: "Software patents in Europe could be validated with a central patent court", warns Richard Stallman in an article published in the Guardian. After the rejection of the software patent directive in 2005, large companies has shifted their lobbying towards the validation of software patents in Europe through a central patent court, which is foreseen with the Unitary Patent project. Even if the European Patent Convention literally excludes software from patents, the European Patent Office and the German courts interprets the exclusion narrowly, which makes software patents valid at the end.
