When does Activision's rights to make TMNT games expire?

[Mugic]

I'm going to be honest, i don't think Activision cares enough about the TMNT name,most of their TMNT games are mobile games or have low-key releases, I feel the Out of the shadows was the only games they ever place any effort into, heck i think Ubisoft despite some of their TMNT games being sort of bad quality wise actually put more love and effort into their games than Activision.
