Patent information

Every patent granting authority has a register in which you can find the status of a patent.

By searching the patent register you can answer the following questions:

  • Is the patent granted?
  • Is the patent still valid?
  • When can I use the technique described in the patent?

Dutch patent register

You can use the Dutch patent register in order to investigate whether a patent is still valid in the Netherlands. This database contains information about published patent applications, patent rights and certificates in the Netherlands since 1912.

The European register

The European Patent Register contains all the publicly available information on European patent applications as they pass through the grant procedure, including oppositions, patent attorney/EPO correspondence and more.

Other registers

If you would like to know whether a patent is still valid in another country, please refer to the patent register of that country or telephone the national patent office of that country. You can find links to the websites of national patent offices on the EPO website.
