John has argued 12 cases in the United States Supreme Court since 2011, more than all but a handful of private attorneys nationwide during that period. His Supreme Court briefs have earned three Best Brief Awards from the National Association of Attorneys General, one for each of the three years he served as Michigan Solicitor General. A recent study of the Court's 2012-15 Terms concluded that John's cert. petitions had one of the highest grant rates in the country. Another recent study on "clutch" Supreme Court practitioners included John in its "veritable who's who of Supreme Court litigators" list,  and yet another recognized John as having the 3rd highest success rate for persuading Justices to adopt his legal position among frequent Supreme Court advocates who did not work for the federal government.


The subject matter of John's Supreme Court cases has ranged from constitutional questions to telecommunications law to intellectual property. In the 17 merits decisions he has received - 14 following oral argument (including two that John briefed but a colleague argued) and three as summary decisions - his client has prevailed ouright in 12 and obtained partial relief in two more, compiling a record that the National Law Journal observed "even more veteran high court advocates would envy."
