Person X now works at Corporation B. He/she earlier worked at Corporation A - a consultant for other businesses, where he/she was involved in business development, creation of new ideas and execution of projects for Corporation A'a clients. Corporation B is a B2C setup and sells what it produces to the end user. At Corporation B, Person X's role involves management of teams within Corp B and management of suppliers to Corp B.
Person X has do a project for Corporation and suppliers to Corp B will present ideas for project. Person X will play a role in approving / rejecting / modifying the final idea for the project. Person X, owing to his/her experience at Corp A, has an idea (let's call it 'Conzept' )that may work very well for Corp B. However, Conzept was conceived 'collectively' by person X and his/her team during a brainstorming session at Corp A some years ago. Conzept was presented to Corp A's client along with other ideas, and, Conzept was not chosen by Corp A's client then because some other idea fit the client's requirement better. Now the team at Corp A has changed, most people of the brainstorming team are employed in other companies. Person X has asked a person from the original team who still works at Corp A if Conzept was presented again to any other client and approved / used by them. Apparently, Conzept was not presented again, neither the original team nor Corp A showed interest in it again and Conzept lies forgotten. Person X has checked online to see if Conzept or any idea related to it exists online and nothing of that sort exists. Also, Corp A has not patented Conzept and no intellectual property right exists over it,
A modified Conzept, if chosen and implemented by Corp B, will work successfully in its favour.
Should Person X present a modified Conzept to his/her team at Corporation B with the knowledge that, if chosen, Conzept will become the intellectual property of Corp B and Corp B stands to gain much from the successful implementation of Conzept.
