Turns out the Google search bar on your iPhone doesn’t come cheap.

According to court documents filed in Oracle’s lawsuit against Google, the latter tech giant reportedly paid device maker Apple $1 billion in 2014 to keep its search bar on the iPhone, Bloomberg reported.

The revelation is just one of many that have sprung up as a result of the Oracle lawsuit.

Bloomberg’s report indicated that the tech titans also have an agreement that gives Apple a cut of the revenue Google makes through the iPhone. Court testimony suggested that the revenue share was “34 percent,” but wasn’t clear on whether that was the percentage paid to Apple or retained by Google.

Additionally, Oracle’s attorney stated in court that Android has produced $31 billion in annual revenue and $22 billion in profit for Google to date. The claim prompted Google to ask the judge to eliminate such “extremely sensitive information” from the public record.

The legal battle between Oracle and Google has been ongoing since August 2010, when Oracle filed suit against Google over its use of Java technology in the Android operating system. The complaint, filed with the U.S. District Court of Northern California, sought unspecified damages from Google and an order permanently enjoining the company from continuing to violate Oracle’s patents.

Last year, the case escalated all the way to the Supreme Court, where the justices rejected Google’s request to review an appeals court ruling.

The case is now in the hands of U.S. District Judge William Alsup in San Francisco. Damages in the case are now predicted to exceed $1 billion after Oracle added more recent versions of Android to its claims.
