IBM announced today that it is donating 500 patents to the open-source community. But some Europeans see this latest move in the battle for open-source mindshare as less than altruistic. The big debate on the continent is whether discard software patents, a decision that could have dire consequences for technology giants such as IBM and Microsoft. "I think IBM is trying to kill two birds with one stone," said Florian Mueller at Munich-based NoSoftwarePatents.com, in an interview with Information Week. "IBM wants to appease the open-source people in the U.S. and simultaneously influence the political debate over patents in Europe."
