David, it is not just an idea and it is part of the solution I provided to the company during the verification of my solution. They have asked me to explain it to them and they never said that they have developed the same idea already themselves during that time.
I think if they say now they had the idea before I showed them mine, do you think the company would provide evidence to say that they have similar ideas?
Who asked you to present to them, did you offer or did they engage in a contract to troubleshoot or was it simply you telling them first?
Generally, I have had companies present at meetings with investors and not disclose their development as a matter of protecting their inventions and products as well and if you did not ask, they will not disclose. They will state is is not an option to discuss their sensitive info.
Exchange docs first then worry about the egos..
I think the horse has bolted and if it is common knowledge it is not patentable. You could have registered designs and copywritten documents and dated them and even had them notorised by a JP or similar but in Australia, it is first to file and in the US it is first to prove their invention. If you did not file, all over red rover.
