sfcrazy writes "Google has announced the Open Patent Non-Assertion (OPN) Pledge. In it's pledge Google says that they will not sue any user, distributor or developer of open-source software on specified patents, unless first attacked. Under this pledge, Google is starting off with 10 patents relating to MapReduce, a computing model for processing large data sets first developed at Google. Google says that over time they intend to expand the set of Google’s patents covered by the pledge to other technologies."
