There is still time to lobby your MEPs. Please spare 5 minutes to send an email registering your concerns. The proposed directive on the patentability of computer-implemented inventions comes before the European Parliament later this month. Patenting of software is a threat to all business models, but especially Open Source (including Free) software. It also penalises software developers and users of all types of software.
Dan Bricklin (who invented the electronic spreadsheet in 1979 but did not patent it) explains why at http://www.bricklin.com/patentsandsoftware.htm
