In a split decision delivered June 21, the U.S. Supreme Court resolved the dilemma created by the constitutional non-reviewability of decisions rendered by the Patent Trial and Appeal Board (PTAB). The Supreme Court’s solution is to make those PTAB decisions reviewable by the director of the Patent and Trademark Office (PTO), although the PTO director’s discretion regarding which PTAB cases should be reviewed may itself prove highly controversial in the months and years to come.
