Got sued for an AMIGA game made with BACKBONE in 2015!
My bro suggested that these legal companies are often retained by the actual copyright holders to pursue any copyright matters and they are probably acting without the parent companies knowledge of the particular case. He suggested you contact the actual owners of the copyright and explain the situation (free game in non competing market) and see if they will stop the action or grant you usage as long as its clearly marked as unaffiliated with the copyright owners (and remains free).
Also keep in mind for any copyright claim to remain valid they must actively defend the IP.
