ClairSign is a private company: we are not INPI, not the Guichet unique and not a public service. INPI does not sell electronic signatures. We provide the signature its Guichet unique requires, and you complete your filing yourself on the INPI website. The filing itself remains free or paid under INPI’s own rules, independently of our service.
