In 1978, the writer and publisher clashed over issues of creative control, and Gerber was abruptly removed from the series. On August 29, 1980, after learning of Marvel's efforts to license Howard for use in film and broadcast media, Gerber filed a copyright infringement lawsuit against Marvel corporate parent Cadence Industries and other parties, alleging that he was the sole owner of the character. This was one of the first highly publicized creator's rights cases in American comics, and attracted support from major industry figures, some of whom created homage/parody stories with Gerber to fund a lawsuit against Marvel; these included Destroyer Duck with Jack Kirby. The lawsuit was settled on September 24, 1982, with Gerber acknowledging that his work on the character was done as work-for-hire and that Marvel parent Cadence Industries owned "all right, title and interest" to Howard the Duck and the Howard material he had produced. On November 5, 1982, Judge David Kenyon approved the motion and dismissed the case.
