Oracle sued Google in 2010 over copyright and patent infringement allegations for its use of the Java programming language in Android, now the world's most popular mobile operating system. Oracle obtained the rights to Java when it acquired Sun Microsystems.
Google has said that under fair-use laws it didn't need a license for the open-source software.
"We welcome the Supreme Court's decision to review the case and we hope that the Court reaffirms the importance of software interoperability in American competitiveness," said Kent Walker, Google's senior vice president of global affairs, in an emailed statement on Friday. "Developers should be able to create applications across platforms and not be locked into one company's software."
Oracle, however, says fair use is no way to describe how Google tapped into Java.
"We believe the Court will reject any reasoning that permits copying verbatim vast amounts of software code, used for the same purpose and same way as the original," said Oracle's Deborah Hellinger in an emailed statement Friday. "That is not 'transformative,' and certainly not fair use."
