I conceived of a piece of software while employed with company A. That
software was implemented and is being offered in the marketplace. I signed
no intellectual property (IP) agreements and no confidentiality or
non-disclosure agreements. I did sign an employment agreement that
mentions
that employment is "contingent" on signing IP and non-disclosure
agreements.
I did not sign any such agreements and non were offered to me to sign.
The issue is that now that I'm not with the company any more, I'd like to
build a similar product from scratch and with it start a new company. I
don't have any source code of company A's product.
Can I do this without getting into legal trouble? If not, what kind of
legal
problems could I run into?
They probably own *that* software if you did it on their time, in their
shop, and so on; I think you can start from scratch and develop your own
product, assuming you infringe no patents or trademarks. There probably are
no patents (or I presume you'd be an inventor and know about it) so don't
call it the same thing, avoid a similar appearance, etc. Obviously you
cannot appropriate large blocks of code from the first product into your new
product or you'll infringe the copyright.
