Google LLC v. Oracle America, Inc.

593 U.S. 1 (2021); 141 S. Ct. 1183

Facts

Oracle owned copyright in the Java SE computer platform.
Java included packages containing “declaring code,” which identified commands programmers could use, and “implementing code,” which performed the underlying functions.
Google developed the Android mobile operating system.
To allow programmers familiar with Java to use familiar commands, Google copied approximately 11,500 lines of declaring code from 37 Java API packages.
Google wrote its own implementing code for Android.
Oracle alleged that the copied declarations were protected and that Google’s use was not fair.
A jury found fair use, but the Federal Circuit reversed.
The case reached the United States Supreme Court.
The Supreme Court assumed, without finally deciding, that the declaring code was copyrightable and addressed fair use.

Whether Google’s copying of Java API declaring code constituted fair use.
How fair use applies to functional computer interfaces.
Whether copying code necessary for programmers to use familiar commands is transformative.

Fair use is assessed through:
purpose and character of the use;
nature of the copyrighted work;
amount and substantiality copied;
effect on the potential market.
Computer programs often lie close to the boundary between protected expression and unprotected systems or methods.
A use may be transformative where it employs existing material for a different technological environment or purpose.
Commerciality is relevant but not conclusive.
The amount copied must be evaluated in relation to the legitimate purpose of the copying.
Market harm concerns substitution for the copyright owner’s protected market, not merely lawful competition.

The declaring code differed from ordinary literary expression.
Its principal role was to organise commands and connect programmers’ chosen instructions with implementing code.
Programmers had invested time in learning the Java command structure.
Google copied the declarations so that programmers could use that accumulated knowledge in a new mobile environment.
Android did not simply repackage Java SE for the same desktop market.
Google created a new platform for smartphones and wrote millions of lines of new implementing code.
The copied declarations formed a small portion of the overall Java codebase.
Google copied only what was necessary to preserve the familiar command structure.
The Court considered the use transformative because it allowed programmers to use familiar skills in a distinct computing environment.
Although Android was commercially successful, commercial purpose did not outweigh its technological and creative transformation.
Oracle argued that it could have licensed Java for mobile devices.
The Court found that Android was not merely a substitute for Java SE and that overly broad control over interface commands could impede future software development.
Copyright should not create a lock over programmers’ acquired knowledge where reuse of an interface is necessary to create a new system.
The functional nature of declaring code therefore substantially influenced the fair-use analysis.

The Supreme Court held that Google’s copying of the Java declaring code was fair use as a matter of law.
The decision did not finally determine whether API declarations are copyrightable.
It instead held that this particular reimplementation for Android lawfully used the copied material.
Use this case for: reimplementation of functional software interface code may be fair use where it enables programmers to use familiar commands in a new and transformative platform.
