Oracle sued Google in August over alleged intellectual-property violations in Android. On 27 October, Oracle updated its complaint with more specifics, including a number of exhibits purporting to show "line-for-line" copying by Google.
Google's answer to that filing "specifically denies that Google has infringed or is liable for any infringement of any valid and enforceable copyrights or copyright rights of Oracle." The company also denies that one of Oracle's exhibits "contains a true and correct copy of a class file from either Android or 'Oracle America's Java.'"
In addition, Oracle has "redacted or deleted from the materials shown in Exhibit J both expressive material and copyright headers that appear in the actual materials, which are significant elements and features of the files in question," Google argued.
An Oracle spokeswoman declined comment.
Oracle is seeking an injunction to stop Google from infringing on its patents, as well as triple damages. Google has termed the suit a "baseless" action that also goes against open-source software in general.
Meanwhile, the case may go to trial next October, according to another document filed Wednesday.
