Oracle wants a technie to tell the court that Google owes it billions while Google wants a marketing expert. The court needs to settle the question of the contribution Oracle's Java-related intellectual property rights make to Android's success. Google thinks that an industry expert would be more helpful to the Court and the jury than a technical expert.
An industry expert would have first-hand knowledge of the market for handsets, operating systems, and applications, how those products are marketed to consumers, and the reason why consumers make their practical purchasing decisions. Analyst Florian Mueller thinks it is really funny as Google always likes to present itself as a company with a markedly "geeky" culture. Oracle's leadership is more like a group of marketeers and investment bankers. They are business-oriented.
“Google obviously wants to downplay the role Oracle's Java IPRs play, claiming that anything those patents (and copyrights) cover is just a small part of Android as a whole,” he said.
