I contacted a company that run fantasy sports in March 2017. My initial approach was to the HR Manager expressing my interest in joining their company in full employment. My email was responded to informing me it would be passed on to the GM and saying "it would be great for you two to catch up for a coffee at some stage". This began a series of email and phone correspondence leading to a meeting - throughout all of this I was of the genuine belief that the purpose was consideration for employment. In this actual meeting I discussed and elaborated on my ideas, visions and own specialised sports stats spreadsheet. Towards the end of this meeting it became clear that there was no job and they weren't interested in employing me - but just wanted my ideas. They have since commenced implementing those ideas. Do I have any form of Intellectual Property claim here?
