A security incident has been identified in the Belgian eFiling web application. Thanks to the rapid detection of the incident, the affected systems were immediately secured. However a limited amount of user account data and a potentially limited selection of patent data have been exposed.
An initial analysis indicates that primarily the Belgian (BE) Patent office is affected; there is currently no evidence that the Dutch (NL) or Luxembourgish (LU) Patent offices are affected, though investigations are still ongoing.
As a precautionary measure the Online Filing platforms for BE, LU, NL have been taken offline until the analyses are complete and security can be guaranteed. This analysis is ongoing and will be on going all the next week. We will inform you when Online Filing is available again.
While the platform is offline, submissions can be sent to the Netherlands Patent Office via
e-loket (https://login.rvo.nl/accessrouter/eloket/login1) or, per post. If you need a submission date, you can also submit the documents in person at the Netherlands Patent Office. You will need to make an appointment for this first.
As a precautionary measure, we ask you to remain vigilant regarding any suspicious emails, text messages etc. that may be phishing attempts impersonating the Patent Office.
If you receive a suspicious message or notice any unusual activity on your account:
