Summary
This Federal Circuit opinion resolves consolidated appeals concerning inventor Gilbert P. Hyatt’s decades-long patent prosecution disputes with the United States Patent and Trademark Office. The court affirms the district court’s ruling in favor of the PTO, holding that Hyatt’s unreasonable delay in prosecuting his patent applications warranted dismissal under the affirmative defense of prosecution laches. Furthermore, the court agrees that the district court lacked Article III jurisdiction over certain pending claims for which the Patent Trial and Appeal Board had already reversed examiner rejections, as Hyatt failed to demonstrate a cognizable injury or standing for those specific claims.

We also affirm the district court’s determination that it lacked Article III jurisdiction over certain pending claims.” (at end)
Factual background
Gilbert P. Hyatt, a patent agent, filed roughly 400 patent applications in the early 1990s (the “GATT Bubble Applications”). The Patent Office examiner rejected most claims; the Board of Patent Appeals affirmed or reversed those rejections. Hyatt sued under 35 U.S.C. §145 in district court, asserting that the PTO’s prosecution‑laches defense should not apply. The district court granted judgment for the PTO on laches and held it lacked Article III jurisdiction over certain pending claims.
Procedural history
Hyatt filed four §145 actions seeking patents on GATT‑bubble applications. The district court ruled on prosecution laches and held it lacked Article III jurisdiction over claims where the Board reversed examiner rejections. The PTO appealed the laches rulings; Hyatt cross‑appealed the jurisdiction rulings. The Federal Circuit vacated and remanded the laches issues, then affirmed the district court’s judgment on both laches and jurisdiction.
