That all sounds complicated and open to debate. Was Jeremy an employee? Did Kyle have any standing to fire him? What were the circumstances under which Jeremy left? Did Kyle use any primary IP contributions from Jeremy, like architectural designs?

Also, if there is sufficient evidence to declare that the 50/50 partnership existed, then Jeremy did not have to do anything to explicitly declare or let Kyle know that he (Jeremy) understood himself to still possess a 50% stake. There would be no such thing as an "implicit acceptance" of losing equity.

Basically the points you raise are not at all obviously addressable, and there are many ways they could play out that actually do support a significant award to Jeremy, regardless of whether that is a popular outcome.
