The United States Supreme Court handed down its decision in Quanta v LG Electronics in June, 2008, and the unanimous, relatively short opinion has raised more questions than it perhaps answered. Professor Shubha Ghosh, now of The University of Wisconsin Law School, wrote an amicus brief on behalf of the American Antitrust Institute supporting the side that was ultimately victorious. In the following commentary, he divides his comments into three parts here: (1) what the case is about, (2) what the Supreme Court opinion says, and (3) what the Court’s opinion means. This analysis originally appeared as “The Quandary of Quanta: Thoughts on the Supreme Court Decision One Week Later” in the June 17, 2008 Antitrust and Competition Policy Blog. Read the Commentary.
