SAN FRANCISCO (Reuters) - Google's Android operating system has generated revenue of about $31 billion and profit of $22 billion since its release, an Oracle Corp lawyer told a U.S. court hearing the software company's copyright lawsuit against Google.
A lawyer for Google did not discuss the figure, according to a transcript of the hearing in a Northern California federal court last week. But he said the Alphabet Inc unit might be willing to disclose more information about the revenue produced by Android as part of the court proceedings, the transcript reviewed by Reuters showed.
The Android mobile operating system began with the release of the Android alpha in November 2007. The first commercial version, Android 1.0, was released in September 2008.
Oracle is accusing Google of using its Java software without paying for it to develop Android.
Google said in a court filing on Wednesday that the Android disclosures should not have been made public, and asked the court to place it under seal.
Google was not immediately available for comment. Oracle declined to comment.
The closely watched case involves how much copyright protection should extend to the Java programming language, which Google used to design the operating system. Oracle is seeking royalties for Google's use of some of the Java language, while Google argues it should be able to use Java without paying a fee.
Bloomberg previously reported the Oracle lawyer's comment.
