This episode concerns an opinion from the United States Court of Appeals for the Federal Circuit regarding a patent dispute between Fortress Iron, LP and Digger Specialties, Inc. The court affirmed a lower court's ruling that two of Fortress's patents were invalid because they failed to name Hua-Ping Huang, an essential coinventor who could not be located. Under 35 U.S.C. § 256, a patent may be corrected to include missing inventors only if all parties receive proper notice and a hearing, a requirement Fortress could not fulfill. The judges rejected the argument that a patent remains valid if at least one inventor is listed, clarifying that all contributing inventors must be identified. Ultimately, because the inventorship error was uncorrectable due to the inability to contact Huang, the patents were rendered legally unenforceable.
