ectoman writes "Are firms responsible for GPL violations on code they receive from third parties? A German court thinks so. The Regional Court of Hamburg recently ruled that Fantec, a European media player maker, failed to distribute 'complete corresponding source code' for firmware found in some of its products. Fantec claims its third-party firmware supplier provided the company with appropriate source code, which Fantext made available online. But a hackathon organized by the Free Software Foundation Europe discovered that this source code was incomplete, and programmer Harald Welte filed suit. He won. Mark Radcliffe, an IP expert and senior partner at DLA Piper who specializes in open source licensing issues, has analyzed the case—and argued that it underscores the need for companies to implement internal GPL compliance processes. 'Fantec is a reminder that companies should adopt a formal FOSS use policy which should be integrated into the software development process,' he writes. 'These standards should include an understanding of the FOSS management processes of such third-party suppliers. The development of a network of trusted third-party suppliers is critical part of any FOSS compliance strategy.'"
