On October 28, 1986, Harvey Films had a lawsuit with Columbia Pictures claiming that the logo for the film Ghostbusters was similar to the logo for The Ghostly Trio, specifically the ghost in the logo was similar to Fatso, and Columbia argued that Fatso was only a portion of their, at the time, renewed trademark, and there were three ghosts instead of just one. The court argued that the logos are largely dissimilar and that The Ghostly Trio had only the words of the trademark and the three ghosts while the logo for Ghostbusters has a sign for prohibition with only the torso and head of only one ghost.
A case between Harvey Films and Columbia Pictures on October 28, 1986, centered on allegations that the Ghostbusters logo bore a striking resemblance to The Ghostly Trio's logo, with specific attention to the ghost in the Ghostbusters logo being similar to Fatso from The Ghostly Trio.
