I like coding up various projects in my free time, and there's the potential for one of them to gain a little traction now that my employer wants to use it to promote their API. It was largely put together before I worked there, but it's being constantly improved and updated.
I've talked to them and they're cool that I'll continue to own the IP. However, I also want to get confirmation in writing to be doubly sure, but I'm not sure what such a document or contract would look like. Does anyone have an example or pointers? More general suggestions are welcome too!
Anecdotally, my employment contract has a clause that grants my employer shared copyright to all my work unless they officially disclaim interest, but because that clause exists there's also a pretty simple process: I present a 1-paragraph overview of the project and someone with signatory authority writes on the paper "[My employer] is not interested in this project." Then signs it.
I don't know how well this would stand up if it ever came down to a court case, and there's definite benefit in that there's only 8 of us here so pinning down such an authority is a matter of me putting the paper on the desk next to mine.
