"Google Inc.’s Android operating system has generated revenue of $31 billion and $22 billion in profit, a lawyer for Oracle Corp. said in court while disclosing figures Google says shouldn’t have been made public.
An analysis of the search engine giant’s tightly held financial information was disclosed Jan. 14 by an Oracle attorney in the database maker’s lawsuit accusing Google of using its Java software without paying for it to develop Android. Google said in a court filing that the lawyer based her statement on information derived from its confidential internal financial documents."
