If you disclose an invention, are you still able to file for trade secrecy? Say I have an invention that I have already disclosed. I am now trying to seek a form of Intellectual Property for it. Am I still able to seek trade secrecy since I've already disclosed about the invention? If I can't file for trade secrecy, am I still able to file for a patent?
No. Trade secrets are not registered. Voluntary disclosure pretty much destroys trade secret status. If you want to have a trade secret, don't tell anyone without a non-disclosure agreement in place. A patent may be available to you depending on your jurisdiction. Consult an attorney in the location where you want to protect your invention.
