What changed

The EPO published patent application EP3733058A1 titled 'Device for Recording the Vascular Response of the Human Spinal Cord Triggered by a Suprasensible Stimulus Through the Use of Functional Near-Infrared Spectroscopy.' The applicant is Pontificia Universidad Católica De Chile with inventors including Felipe Ignacio Valenzuela Beck, Sergio Andrés Uribe Arancibia, Antonio Alejandro Eblen Zajjur, Ranganatha Sitaram, and Mohit Rana. The technology covers the use of fNIRS for recording spinal cord vascular responses to suprasensible stimuli. The designated states include all EU member states plus other European countries.

Organizations developing similar neurovascular monitoring technology should review the patent claims for potential freedom-to-operate implications. No immediate compliance actions are required. Patent applications undergo examination before grant, and granted patents may be subject to opposition.
