Background
Thales filed French patent application No. 10 04947 for a “Method for the temporal display of an aircraft mission.” The claims described displaying flight-plan stages on a screen along a time-based scale, or “timeline,” including a user-selected portion of a timeline longer than the graphical window. Dependent claims addressed automatic recentering, a magnifying function, a map view, arrangements using one or more screens, and coordinated movement between the timeline and an aircraft symbol on the map.
On July 17, 2018, the Director General of the National Institute of Industrial Property (INPI) rejected the application because it concerned only a presentation of information associated with a mathematical method and lacked technical characteristics under Article L. 611-10(2) of the Intellectual Property Code. Following an earlier cassation and remand, the Paris Court of Appeal rejected Thales’s challenge on March 26, 2025. Thales then appealed to the Court of Cassation.
The Court’s Holding
The Court of Cassation dismissed Thales’s appeal and upheld the rejection of its patent application. It held that a claim confined to the information displayed and the forms of presentation is not a patentable invention unless it identifies a technical device or means producing a technical effect that contributes technically to the problem stated in the application. The asserted effect must rest on an objectively reliable causal connection between the claimed feature and assistance provided to the user in performing a technical task; an effect dependent on the user’s subjective interests or preferences is insufficient.
The Court also clarified that the technical character of a claim is assessed at the patent-eligibility stage, separately from the invention’s contribution over the prior art, which belongs to the inventive-step analysis. Because this application predated the relevant PACTE Law changes, INPI was not examining inventive step and could consider only whether the claimed subject matter constituted an invention.
The Court agreed that claim 1 merely presented flight information on a timeline without claiming technical means distinct from that presentation. Mentioning a display screen, partial timeline views, or zooming did not establish the required technical contribution where the claims and specification did not disclose relevant technical interaction means, a distinct technical problem, or a technical task facilitated by those features. The same reasoning applied to claims 3 through 7: recentering, magnification, map displays, screen arrangements, and coordinated symbol movement remained presentations of information without a claimed technical contribution or characterized human-machine interaction.
Key Takeaways
- A presentation of information is not patentable merely because it appears on a screen or concerns operational information such as an aircraft mission.
- Eligibility requires a claimed technical device or means producing a credible technical effect that contributes to solving the problem identified in the application.
- A display that allegedly assists a user must have an objectively reliable causal connection to performance of a technical task; subjective usefulness or preference is not enough.
- Technical character is assessed for patent eligibility, while contribution over the prior art is assessed separately as part of inventive step.
Why It Matters
The decision provides a structured test for French patent applications directed to graphical interfaces and information displays. Applicants cannot establish technical character solely by placing informational content on conventional hardware or by labeling display operations as zooming, recentering, or synchronized movement.
For interface-based inventions, the claims and specification should identify the relevant technical means, the technical task or problem addressed, and a credible causal link between the claimed feature and the resulting technical assistance. The ruling is particularly significant for cockpit displays and other decision-support interfaces whose value may otherwise be characterized as cognitive presentation rather than technical contribution.
