According to an article on InfoWorld, Oracle have ammended their lawsuit against Google with specific detail. The stand-out quote from this ammendment has to be "in at least several instances, Android computer program code also was directly copied from copyrighted Oracle America code."
"The infringed elements of Oracle America’s copyrighted work include Java method and class names, definitions, organization, and parameters; the structure, organization and content of Java class libraries; and the content and organization of Java’s documentation,"
The following article gives an idea of how much detail Oracle are prepared to go to in this lawsuit, with code snippets to highlight the degree of "copying" and statements such as
"For example, as may be readily seen in Exhibit J, the source code in Android’s “PolicyNodeImpl.java” class is nearly identical to “PolicyNodeImpl.java” in Oracle America’s Java, not just in name, but in the source code on a line-for-line basis. "
So it looks like Oracle have no intention of standing down on this.
