Chief Justice John Roberts withdrew from a U.S. Supreme Court patent case argued last month after belatedly discovering that his stock holdings had created a possible conflict of interest.

Roberts owns 1,212 shares of Thermo Fisher Scientific Inc., whose Life Technologies unit is embroiled in a patent fight with Promega Corp. over genetic testing kits, a court official said in a letter released Wednesday. The letter said Roberts had discovered that Thermo Fisher owns the unit.
