I have developed a new algorithm and then found a potential partner to commercialise it. We went though some verification stages. No issues have been found during the time. I exposed the critical idea of my modelling to them. I did not sign any non disclosure agreement (NDA) with the company. I recently found that a new product was released from that company which has quite similar to my algorithm. Any suggestion on what I can do about it? Any recourse under intellectual property law?
