The district court ruled for Google over patents and copyright- that it was not a copyright at all, the Court of Appeals then reversed and demanded a second court trial on whether Google was doing fair use of Oracle's legitimate copyright, which the district court again held for Google, and then the Court of Appeals reversed the second ruling and held for Oracle that it was not fair use of their copyright, and then Google appealed that to the the Supreme Court ... and won in April 2021, putting an end to this case which was filed in August 2010. But the appeals court in between the district court and the Supreme Court meant that for a long while in the middle Oracle was the winner.

This is part of why patents and copyrights can't be the moat for your company. 11 years, with lots of uncertainty and back-and-forth, to get a final decision.
