 Stemming from the publishing of several Sega Genesis games by video game publisher Accolade, which had disassembled Genesis software in order to publish games without being licensed by Sega, the case involved several overlapping issues, including the scope of copyright, permissible uses for trademarks, and the scope of the fair use doctrine for computer code.The case was filed in the U.S. District Court for the Northern District of California, which ruled in favor of Sega and issued an injunction against Accolade preventing them from publishing any more games for the Genesis and requiring them to recall all the existing Genesis games they had for sale.Accolade appealed the decision to the Ninth Circuit on the grounds that their reverse engineering of the Genesis was protected under fair use.
