Sony Computer Entertainment, Inc. v. Connectix Corp.

Court of Appeals for the Ninth Circuit
203 F.3d 596, 2000 WL 144399 (2000)
ELI5:

Rule of Law:

Intermediate copying of copyrighted computer software during reverse engineering is a fair use when it is necessary to gain access to the unprotected functional elements of the software, and the resulting product is transformative and non-infringing.


Facts:

  • Sony Computer Entertainment, Inc. (Sony) develops, manufactures, and distributes the Sony PlayStation console, which plays games from compact discs and contains copyrighted firmware known as the Sony BIOS.
  • Connectix Corporation (Connectix) created a software program called 'Virtual Game Station' (VGS) designed to emulate the Sony PlayStation console, enabling computer owners to play Sony PlayStation games on their personal computers.
  • To develop the Virtual Game Station, Connectix engineers purchased a Sony PlayStation console, extracted the Sony BIOS from a chip inside, and copied it into the RAM of their computers.
  • Connectix engineers repeatedly copied and observed the functioning of the Sony BIOS, and disassembled discrete portions of it, to understand its functional elements and to debug their hardware emulation software.
  • Connectix also made daily copies of the Sony BIOS to develop certain Windows-specific systems for the Virtual Game Station for Windows, utilizing the CD-ROM code present in the Sony BIOS.
  • Early in development, a Connectix engineer disassembled a downloaded copy of the entire Sony BIOS to test a disassembler program, but this Japanese-language version was not used for the final emulator.
  • Connectix completed and marketed the Virtual Game Station for Macintosh computers as a 'PlayStation emulator,' advertising that it permitted users to play 'their favorite Playstation games' on a computer.
  • The Virtual Game Station software itself did not contain any of Sony’s copyrighted BIOS material.

Procedural Posture:

  • On January 27, 1999, Sony Computer Entertainment, Inc. (Sony) filed a complaint against Connectix Corporation (Connectix) in district court, alleging copyright infringement and other causes of action.
  • Sony subsequently moved for a preliminary injunction based on its claims of copyright and trademark infringement.
  • The district court granted Sony's motion for a preliminary injunction, enjoining Connectix from copying or using the Sony BIOS code in developing the Virtual Game Station for Windows and from selling the Virtual Game Station for Macintosh or Windows.
  • The district court further ordered the impoundment of all Connectix’s copies of the Sony BIOS and all works based upon or incorporating it.
  • Connectix appealed the district court’s order granting the preliminary injunction to the Ninth Circuit Court of Appeals.

Issue:

Does the intermediate copying and use of copyrighted computer software during a reverse engineering process constitute fair use under 17 U.S.C. § 107 when the purpose is to gain access to unprotected functional elements to create a new, transformative, and non-infringing product?


Opinions:

Majority - Canby, Circuit Judge

Yes, the intermediate copying and use of copyrighted computer software during a reverse engineering process constitutes fair use under 17 U.S.C. § 107 when the purpose is to gain access to unprotected functional elements to create a new, transformative, and non-infringing product. The Ninth Circuit reversed the district court's preliminary injunction, holding that Connectix's intermediate copying of the Sony BIOS during reverse engineering was protected as fair use. The court applied the four statutory fair use factors from 17 U.S.C. § 107, guided by its precedent in Sega Enterprises Ltd. v. Accolade, Inc., which recognized that disassembly is fair use when it is the only way to access functional elements of a copyrighted program for a legitimate reason. First, regarding the nature of the copyrighted work, the Sony BIOS was deemed to be 'at a distance from the core' of copyright protection because it contained unprotected functional elements that could not be accessed without copying. This factor strongly favored Connectix, as the copying was 'necessary' to gain access to these elements, and the court rejected an artificial distinction between 'studying' and 'use' of the code. Second, concerning the amount and substantiality of the portion used, while Connectix copied the entire BIOS multiple times and disassembled parts, this factor was given 'very little weight' in cases of intermediate infringement where the final product itself is non-infringing, citing Sega and Sony Corp. of Am. v. Universal City Studios, Inc. Third, for the purpose and character of the use, the Virtual Game Station was found to be 'modestly transformative' because it created a new platform (personal computer) for playing PlayStation games, making it a wholly new product. The court clarified, citing Campbell v. Acuff-Rose Music, Inc., that Connectix's commercial purpose was merely one factor against fair use, not a presumption of unfairness, and its intermediate use for compatibility was legitimate. Finally, regarding the effect of the use upon the potential market, the court found that this factor favored Connectix. Although Sony might lose console sales, the Virtual Game Station was a legitimate competitor in the market for game-playing platforms because of its transformative nature. Copyright law does not grant a monopoly over such a market, and the court emphasized that preventing competition in this way runs counter to the statutory purpose of promoting creative expression. The court also reversed the district court's finding of trademark tarnishment due to insufficient evidence.



Analysis:

This decision significantly bolsters the fair use doctrine for reverse engineering in the software industry, particularly for promoting interoperability and competition. It clarifies that intermediate copying, even of an entire copyrighted work for a commercial purpose, can be permissible if essential to uncover unprotectable functional elements and if the ultimate product is transformative and non-infringing. The ruling prevents copyright holders from using their copyrights to extend monopolies over functional aspects of their software that would otherwise not be eligible for patent protection, thereby encouraging the development of compatible and competing products. This case provides crucial guidance for developers navigating copyright law in complex technological fields.
