Swedish Patent Database

PRV's online service Swedish Patent Database is a completely free search service. No login is required. The Swedish Patent Database covers:

  • Swedish patents
  • Swedish public patent applications
  • European patents (EP patents) validated in Sweden.
  • European patent with unitary effect (Unitary patents)

    Unitary patents are searchable in the database, but a link will take you directly to the European Patent Register (on the EPO website) for all information about an individual patent.

  • EP applications published under §88 of the Patents Act
  • Granted EP patents where Sweden is designated, meaning the applicant has clearly requested that the patent be made valid in Sweden. (Searchable in the database for six months from EPO’s grant date.)
  • Supplementary Protection Certificates (SPCs) and extensions to SPCs for patents

The patent database includes all the information and documents which are in PRV's archives, spanning from 1885 until the present day. For older patent material, the information may be limited.
