Intel Corporation v. VLSI Technology LLC

Whether the U.S. Court of Appeals for the Federal Circuit may review, by appeal or mandamus, a decision of the U.S. Patent and Trademark Office denying a petition for inter partes review of a patent, when review is sought on the grounds that the denial rested on an agency rule that exceeds the PTO"s authority under the Leahy-Smith America Invents Act, is arbitrary or capricious, or was adopted without required notice-and-comment rulemaking.
