How should new suppliers log in to the EPO procurement portal?

If you are not sure if your company is already registered in the EPO’s supplier database, please send a query to supplier@epo.org. We highly encourage new suppliers to register on the portal. For a complete guide to registration, see section 2, “Self-Registration”, in the user guide.
