Was TemTem ever sued by pokemon?

With the recent PalWorld debacle I started doing some more research. I think there's some clear reasons as to why Palworld would be sued and not TemTem (its success was massive, and there was also a lot of discussion from players about whether the designs were too similar).

Apparently (according to some guy on instagram threads) TemTem was once sued by the Pokemon company but it never went anywhere. I have found 0 information to corroborate this online.

I just wanted to confirm for my own curiosity - was there ever a case being built against TemTem that was brought forward?

Because as far as I know the Pokemon company has never lost a case that it initiated. TemTem is also a US based publisher, which may give Pokemon less foothold.
