Our company was recently acquired, and I've been tasked to verify that our software is compliant with respect to open source licenses.Specifically, I have been asked to obtain from software vendors that we purchased libraries from, a document that verifies the purchased software does not contain open source software (OSS) which, by being sold as closed-source, might violate its original license.I am a software developer (not a lawyer), but am familiar with the various licenses that OSS can be distributed under. I am familiar with checking OSS licenses before bundling or embedding it with our own commercial software, however I've not previously been required to question vendors of commercially-licensed software.Is there a particular document that I should be asking for? If so, what is the proper way to refer to it without having to explain the above? I am not looking for legal advice, but instead asking if there's a common name for this procedure (or if this is even commonly done at all).
What should I ask for when verifying open source compliance of purchased commercial software?
