U.S. Supreme Court Administrative Law Decisions Raise Questions for U.S. Patent and Trademark Office Proceedings
Last week, the U.S. Supreme Court decided two important administrative law cases that are expected to increase judicial authority over agency adjudications and rulemaking. In Securities & Exchange Commission v. Jarkesy (decided June 27), the Court held that when the U.S. Securities and Exchange Commission (SEC) seeks civil penalties for securities fraud, the defendant is entitled to a jury trial. In Loper Bright Enterprises v. Raimondo (decided June 28), the Court held that courts should not defer to an agency statutory interpretation. While each ruling might have significant effects on some agencies, their effect on the United States Patent and Trademark Office (USPTO) should be much more limited because, generally, USPTO regulatory authorities are much more limited and because USPTO’s primary reviewing court, the U.S. Court of Appeals for the Federal Circuit, is a specialized court that does not defer to USPTO on legal questions.
