IBM Lawsuit

In October 2016, IBM filed a lawsuit alleging copyright infringement and trade secrets misappropriation against Teraproc. The complaint accused some of the company's founders of taking “confidential and proprietary source code" for IBM's Spectrum LSF product when they left, which was then used as the basis of the competitive product OpenLava. David Bigagli, the TeraProc employee who started the OpenLava project, posted a notice on GitHub announcing that downloads for OpenLava had been disabled because of a DMCA takedown notice sent by IBM's lawyers. Bigagli later announced that the source code for OpenLava 3.0 and 4.0 would be taken down, while the source code of 2.2 would be restored in order to regain the GitHub repository and the openlava.org website, while claiming that the DMCA claim is fraudulent. On September 18, 2018, the US Courts found in favor of IBM and issued a permanent injunction against Teraproc and its agents.
