Twin Peaks Software, Inc., which makes proprietary data replication and cloud storage software, sued Red Hat and its subsidiary Gluster for patent infringement back in February. Last week, Red Hat filed a counterclaim in that litigation, alleging copyright infringement by Twin Peaks in misappropriating GPL’d software. Today SFLC begins an investigation of Twin Peaks’ products, to ascertain whether any of our clients’ rights are being infringed through the violation of FOSS licenses.
Black Duck Software recently published some summary statistics about free and open source software license adoption, based on data it collected by crawling the web. The report lists “top 20 licenses that are used in open source projects” and the proportion of projects which use each license, as well as historical figures purportedly representing the number of projects using and planning to use GPLv3 variants for each month of the last two years. Because of inherent difficulties in collecting this kind of data, and because Black Duck’s own methods are opaque and unverifiable, the report is largely meaningless.
