Google went to appeals court Monday in an attempt to convince a three-judge panel to overturn a jury's verdict declaring its app store for Android smartphones as an illegal monopoly and block the penalties imposed by a federal judge to stop the misbehavior.

Google is preparing to head back to court on Monday to appeal a ruling that found its app store was a monopoly — one of three major antitrust suits against the tech firm.

Apple wants to ensure it has a voice in the remedies trial for the Justice Department’s search monopolization case against Google, and filed an emergency motion to stay the proceedings while it appeals the district court’s denial of its request to be more directly heard in the case.

Google asked a federal appeals court Monday to throw out a federal judge’s ruling stemming from the 2023 antitrust trial where a jury found that Google’s Play Store and billing services on Android platforms constituted an illegal monopoly.
