How do I split the copyright from my employer?
<p>I have gotten permission from my employer to publish a project of mine as open source, but I have the opposite problem from <a href="https://opensource.stackexchange.com/questions/1140/acknowledging-employer-in-an-open-source-project">this question</a>—my employer doesn't want their name associated with the open-source project.</p>

<p>I'm happy to do that, of course, but I want to get the legalities straight. The copyright belongs to them, so if I were to be honest in my copyright statements, I'd have to put their name.</p>

<p>The support for this effort is tepid at best, so I don't want to scare them off. The options as I see them are:</p>

<ul>
<li>Get written permission, but don't put a copyright statement. Someday someone might ask me who owns the copyright, and I'd have to tell them the company's name.</li>
<li>Transfer the copyright to me and give an irrevocable license back that says they can continue to do whatever they want. I like this, but I'm not sure they'll go for it.</li>
<li>Split the copyright, so that my copy is mine and their copy is theirs. I think they'd go for it, but I have no idea if it's legally possible.</li>
</ul>

<p>What should I do?</p>
