Saul Zaentz. He flimflamned a very young John Fogarty into a deal under which Zaentz retained all publishing rights in perpetuity.
When John finally broke away, he was blocked (or at least severely restricted) from performing songs he wrote & made popular.
When he landed on his feet with new material, he fought Zaentz in court for the right to perform his songs in concert.
But when he won, Zaentz was looking for a revenge suit and picked OMDTR because of its similarity to "Jungle".
His suit actually precipitated a long legal battle & negotiation so that John got all his rights to the catalog back.
