Presented with a publishing company defendant’s mashup of Dr. Seuss’ copyrighted works with Star Trek in a work titled Oh, the Places You’ll Boldly Go!, the US Court of Appeals for the Ninth Circuit tackled claims of both copyright and trademark infringement, including the defense of fair use and the use of trademarks in expressive works. The Ninth Circuit reversed the district court’s summary judgment in favor of defendants on the copyright infringement claim and affirmed the district court’s dismissal and grant of summary judgment in favor of defendants on the trademark claim. Dr. Seuss Enterprises, L.P. v. ComicMix LLC, et al., Case No. 19-55348 (9th Cir. Dec. 18, 2020) (McKeown, J.)
