Atari Games Corp. v. Oman was a series of court cases where Atari, a video game developer, challenged the United States Copyright Office for refusing copyright registration for their arcade game Breakout. The Register of Copyrights first rejected Atari's registration in 1987, determining that Breakout lacked sufficient creativity to qualify as an audiovisual work. Atari twice appealed the register's decision before their copyright was granted. Decided in 1992, the case affirmed that video games are protected from clone developers who mimic a game's audiovisual aspects.
