You know, a good lawyer is both good at listening to his client’s goals and good at negotiating. Such a lawyer would avoid a “scorched earth” outcome, if that’s what you want, and also negotiate a better deal than you could on your own. Lawyers who specialize in business transactions are sometimes called transactional lawyers (as opposed to litigators, who specialize in asserting claims in court).

Many lawyers are very good at negotiating. It is part of the job, in many corporate deals idea is not to fuck the counter party but come up with everyone is sort of happy solution.

If you are in Canada I can recommend someone who is good, former software engineer and does IP law.

And both of you will be better off if that thing you work out is sound and in both your interest. Perhaps you’re both happy now, but what about next year? What about when you move to another company? Take the advice: consult with a lawyer.
