The legal battle began in 2010 and the two firms first faced each other in court in May 2012. A federal judge ruled against Oracle, but the company then appealed. After legal wrangling, the case was sent back to court.
Despite Thursday’s outcome, Oracle lawyer Dorian Daley said it would pursue the matter further.
“We strongly believe that Google developed Android by illegally copying core Java technology to rush into the mobile device market,” he said.
“Oracle brought this lawsuit to put a stop to Google’s illegal behaviour.
“We believe there are numerous grounds for appeal and we plan to bring this case back to the federal circuit on appeal.”
