28 F.4th 1214
Fed. Cir.2022Background
- Patent-at-issue: U.S. Reissue Patent RE47,474 ("’474 patent") for an "intelligent" whole-aircraft ballistic parachute system that uses processors to command pre‑ and post‑activation actions (e.g., autopilot commands to change pitch, roll, or attitude) upon receipt of an occupant parachute deployment request.
- Representative asserted claims (137–139) require processors coupled to an activation interface, pitch sensor, autopilot, rocket, and memory; upon a deployment request the system both deploys the parachute and commands the autopilot to change pitch/roll/attitude.
- Petitioner Cirrus filed IPR challenging claims 137–139; the PTAB found claims obvious over a combination of Cirrus’s SR22 Pilot Operating Handbook (POH) and U.S. Patent No. 6,460,810 (James) and denied Fleming’s motion to amend as lacking written description and being indefinite.
- POH discloses Cirrus’s CAPS ballistic parachute and advises deploying from a wings‑level, upright attitude and at higher altitude for better chances of success; it warns about adverse factors (high speed, low altitude, etc.).
- James discloses a semiautonomous flight director that can program autopilots to perform emergency actions (including deploying a parachute and executing flight maneuvers) upon receipt of emergency signals.
- On appeal the Federal Circuit affirmed the PTAB: (1) claims 137–139 obvious over POH+James; (2) proposed substitute claims denied for lack of written description (the "Procedural Selection Limitations" requiring processor‑based selection/activation were not supported).
Issues
| Issue | Plaintiff's Argument (Fleming) | Defendant's Argument (Cirrus/Board) | Held |
|---|---|---|---|
| Whether POH+James teach commanding an autopilot to change pitch/roll/attitude based on an occupant parachute deployment request | The prior art does not disclose commanding an autopilot to perform those maneuvers upon receipt of a parachute deployment request | James discloses automatic emergency procedures (including deploying a parachute) and autopilot actions; POH teaches desirable flight parameters for parachute deployment, so a skilled artisan would combine them to program the autopilot | Affirmed: obvious — a skilled artisan would be motivated to combine James and POH to cause autopilot maneuvers upon a deployment request |
| Whether the prior art teaches away or makes the combination unsafe | Prior art cautions against autopilot use in some emergencies (e.g., low altitude, takeoff/landing), so a skilled artisan would be dissuaded | Warnings are context‑specific; neither reference teaches never to use autopilot in any emergency and James/POH support some autopilot use | Affirmed: no teaching away; safety concerns do not defeat obviousness |
| Whether objective indicia (copying) show non‑obviousness | Fleming’s evidence of alleged Cirrus copying of his disclosures proves nonobviousness | Cirrus provided evidence of independent development and dissimilarities; Fleming’s materials lacked meaningful infringement analysis | Affirmed: PTAB reasonably found Fleming failed to show copying sufficient to carry weight as objective indicia |
| Whether proposed substitute claims meet written description requirement (Procedural Selection Limitations) | Specification/earlier application disclose an "intelligence override" and other passages that support processor‑based selection and activation as claimed | The cited passages describe manual override (pull‑handle/button) and do not disclose processor‑based selection/activation of one of two procedures as claimed | Affirmed: substitute claims lacked written description support; motion to amend properly denied |
