Oracle has extended the scope of its Android Java patent case against Google, claiming that the search giant is destroying the market for Java.
The software firm has filed papers in a US court seeking to include the six most recent versions of Android in its patent battle against Google.
Oracle alleges the six Android releases use thousands of lines of source code from the Java platform it owns.
In the filing, Oracle said, "Although all of these new Android versions are dependent upon the infringing Java code, applications written for these new Android versions are not compatible with the Java platform, because they do not run on the Java platform or on devices implementing the Java platform."
The company said apps written for the Java platform do not run on the versions of Android made available since October 2010.
The widespread dominance that Android achieved in the mobile phone market had done irreversible damage to Java’s potential market, Oracle said, accusing Google of using 37 API Java packages without permission.
Oracle noted that Google’s annual revenue had surged to $66bn from $29bn between 2010 and 2014, with the majority coming through advertising on Android.
The company said Android also helps Google generate revenue from other sources, including from the Google Play store.
