Also, since you posted this before leaving the company, you've also given them documented discovery of your idea that was developed while you were under employment with them.

I'm not trying to be sneaky or hide anything. Like I said, I want to do this in a clean way. If I can't do it, I'll come up with another idea later if/when I don't work for them.
Seems a little silly to have to consult a lawyer before posting to HN. Thanks for your thoughts though (seriously)
That's like saying it's silly to ask a doctor why you have chest pain before you ask Reddit. This is not an area where you want the opinions of a bunch of non-experts. Pay the relatively small amount of money to find out the answer from some who actually understands the relevant law.
Do you always run to the doctor at the first sign of chest pain? I would bet you, or most everyone, does just a little bit of research/asking around first. That's all I'm doing.
