IT is worth repeating...IF ANYTHING is changed, removed/added/redefined/augmented...whether it is currently evident or not...THAT ART belongs to the entity that employed you under contract or NDA agreement. IF you made it for me, while employed by me...I OWN IT...period. Patent Language is very clear. I personally have (2)...and have collaborated with several entities outside on design efforts...Blah...Blah...All NDA'd and ALL paid by me. It is an infringement on rights to the ART owner and is protected by Law.
