While working for my present employer, I developed seminar content of which the only physical manifestation are some Powerpoint slides. The vast majority of the value of this seminar is in the manner of presentation and the overall agenda of the material which is not propriety in any way - meaning it doesn't represent any data that isn't available to the general public.
The material was never presented for renumeration, it was solely for firm name recognition. Based on some research, I believe this seminar has a market and I am leaving my firm to pursue this as a business. I do have a clause in my employment agreement that states any work that I develop under their employ is property of the firm.
I will attempt to get written waiver of some sort before departing - which IS possible as I don't believe the firm would pursue this without me. But in the event that I can't get a waiver, my question is:
How much would I have to alter this material in order for it to be no longer the firm's? Again, it is not proprietary material.
