The European patent for QuantumPath®'s hybrid software system has been validated in Spain
On April 1, 2026, the Spanish Patent and Trademark Office (OEPM) published the validation in Spain of European patent No. EP4231204 [1] in the Official Industrial Property Bulleting (BOPI) [2].
As Spain does not participate in the European Unitary Patent system, it was necessary to validate European patent No. EP4231204 at the OEPM in order to obtain protection rights for it in Spain. Once validated, the European patent confers the same rights as a Spanish national patent. In effect, the European patent becomes a Spanish national patent.
European patents validated through the OEPM are valid for a maximum of 20 years. Once approved, it has the same effect as a national patent. In Spain, the process of validation starts as soon as the protection notice is published in the BOPI.
Detailed information about this patent in Spain is available on the OEPM website.
The authors of this patent, who possess in-depth knowledge of the role this invention plays in QuantumPath®, assert that, although it has not been officially named as such, this patent corresponds to the hybrid software system of the platform’s original CORE.
The article EP4231204 System for developing and executing applications in hybrid quantum computing networks, the QuantumPath® software patent”[3] provides detailed information on the implementation of the invention in the QuantumPath® CORE.
