Oracle and Google's Android copyright trial begins
Oracle's claim that Google violated a number of its patents and copyrights has gone to trial in a San Francisco court.
It is one of the biggest tech lawsuits to date as business software manufacturer Oracle is claiming around $1 billion (£630 million) in compensation.
The Java developers believe Google's Android operating system infringes intellectual property rights relating to its programming language.
US District Judge William Alsup warned both firms that sensitive financial details about each company would be made public.
In a court filing made on Sunday (April 15th), Oracle stated it expected its own and Google's chief executive officers Larry Ellison and Larry Page to be among the first witnesses.
Oracle originally filed a suit against Google over these patent infringements in August 2010.
Chief technology officer at Songkick and a former Google tech team leader Dan Crow told BBC News about the upcoming trial: "If Oracle wins and APIs [application programming interfaces] are held to be copyrighted, then virtually every application - on Android, Mac OS, Windows, iPhone - has to be at least re-released under new licence terms."
