litewoheat writes "I started a software company a while ago that was acquired by a larger company and I now work for the combined company. I basically sold all my IP to the acquiring company, including source code going back 10+ years. I'm in the very early stages of a new startup working on all new software for a completely different market and I'm starting totally from scratch. I'm even developing on a different OS just to keep my distance from the code I've written in the past, which is no longer mine. There's nothing in my contract that says my current employer has rights on anything I develop in my free time etc. I'm integral to my current employer and when I do announce that I am leaving there will be drama. I'm reminded of John Fogerty getting sued because his new music sounded much like his old music that was owned by his old record company. I'm concerned that my current company would do the same to me when I do leave. What kinds of things should I do now that will protect me later when/if this were to happen?"
