Natural Alternatives International, Inc. v. Andrei Iancu, Director, United States Patent and Trademark Office

Did the Court of Appeals for the Federal Circuit err in analyzing rulings by the Patent Trial and Appeals Board when it failed to base its decision on the Board’s stated reasoning that was the only reasoning briefed by the Patent Office, failed to explain its reasons for departing from the agency guidance, and removed patent law from the ambit of normal property law to create a non-statutory exception to property law? When is priority established for a patent application under the Trade-Related Aspects of Intellectual Property Rights (TRIPs) so that a Patent Owner can change priority in one application without affecting the priority of applications that have already established priority?
