Oracle sues Google over use of Java in Android

Business software company Oracle is moving a US federal court against Google alleging patent and copyright infringement.

The dispute relates to the use of Java technology - the programming language used for the Android operating system development.

According to a statement from Oracle, Google "knowingly, directly and repeatedly infringed Oracle's Java-related intellectual property" for the development of Android.

"This lawsuit seeks appropriate remedies," it added.

Oracle acquired Java in a $5.6 billion purchase of Sun Microsystems earlier this year.

Larry Ellison Oracle chief views the Java software as a key asset.
