The Unified Patent Court (UPC) has announced the publication of an updated document “Case Management System. New authentication and electronic signature. How to authenticate to the CMS system”. This follows the document provided recently (reported here) and provides clarification and more guidance about how to access the CMS using its anticipated strong authentication scheme (which will be required from 31 October 2022). It includes more information about suitable providers of the two certificates required, i.e. a Client Authentication Certificate (contained in a smart card or USB token) and an Electronic Signature Certificate.
