Sega Enterprises Ltd. v. Accolade, Inc. was a decision in 1992 by the United States Court of Appeals for the Ninth Circuit that applied American intellectual property law to the reverse engineering of computer software. Issues in the case included the scope of copyright, permissible uses for trademarks, and the scope of the fair use doctrine for computer code. It arose after video game publisher Accolade published several games for the Sega Genesis (pictured), disassembling it to publish games without being licensed by Sega. The U.S. District Court for the Northern District of California ruled in favor of Sega, preventing Accolade from publishing any more games for the Genesis and requiring them to recall all of their Genesis games on sale. Accolade appealed on the grounds that their reverse engineering of the Genesis was protected under fair use. The Ninth Circuit reversed the district court's order and ruled that Accolade's use of reverse engineering to publish Genesis titles was protected under fair use, and that its alleged violation of Sega trademarks was the fault of Sega. The case is frequently cited in matters involving reverse engineering and fair use under copyright law.
