The ongoing dispute between Oracle and Google over Java intellectual property violations will take more time than expected to settle. According to a filing in U.S. District Court for the Northern District of California, yesterday Oracle and Google held discussion over conference and tried to sort out the differences but the meeting failed to reach an agreement.

Oracle had filed a suit against Google in August 2010, alleging infringement of patent and copyrights in the development of the popular Android-based smartphone software. Oracle is claiming that Android violated a number of copyrights and patents it holds on the Java programming language. Google has denied any wrongdoing.

Google filed its response with a California federal court last year saying that the complaint by Oracle alleging patent copyright infringement is vague, involved broad claims, not specifically identifying infringement/s by Google.

But Google had another blow when one of their engineer’s email trail was brought as evidence in the lawsuit.  Google said the email was subject to attorney-client privilege and shouldn’t be disclosed by Oracle.

“What we’ve actually been asked to do by [Google co-founders Larry Page and Sergey Brin] is to investigate what technical alternatives exist to Java for Android and Chrome,” Lindholm wrote in the email to Android chief Andy Rubin. “We’ve been over a bunch of these, and think they all suck. We conclude that we need to negotiate a license for Java under the terms we need.”

Google has some major patent and copyright infringement cases with Oracle, Apple and Microsoft, pouring a great deal of resources into protecting its position in the mobile sector. A growing amount of Google’s revenue comes from Android software, and the more popular Android becomes, the fiercer its competitors get.

But Google is not the only player being dragged to court.  Apple filed a case against Nuevas Tecnologias y Energias Catala, commonly known as NT-K, for violating and copying iPad contents to their tablets, though Apple lost that round.  Then there is the high profile battle between Samsung and Apple, where Samsung continues to face a string of legal woes across various countries, though it’s finding its own ways of fighting back.
