The past year has been one of the most active yet for legal issues relating to open source software. With corporations continuing to use open source software in an ever-widening variety of situations, most can now ill-afford to ignore the impact of these issues on their businesses. In this installment of the Celesq®-West IP Master Series, Jason Haislmaier, a partner with the law firm of Holme Roberts & Owen LLP and the author of the ThinkingOpen blog (www.thinkingopen.wordpress.com), and Stormy Peters, Director of Community and Partner Programs at OpenLogic and co-founder of the GNOME open source foundation, provide a look at these issues and a discussion of what changes they bring for corporate counsel charged with the task of open source compliance. Topics include: - The \"BusyBox\" Lawsuits-the first lawsuits filed in the U.S. seeking to enforce the GNU General Public License (GPL), brought by the developers of the popular open source software application BusyBox; - Open Source Software Patent Infringement-Software patents asserted by and against users and developers of Linux and other open source software such as Red Hat, Novell, Sun Microsystems and Net App; - The Impact of GPLv3-the ongoing use and adoption of version 3 of the most popular open source license in the world; and - Changes in Open Source Compliance-how to evolve your open source compliance efforts beyond merely risk mitigation to help add value to your business.
