Every night, the online Belgian patent register ('eRegister') receives an update with public data that were entered or generated the preceding day on the Benelux Patent Platform, the computer application with which the Belgian Intellectual Property Office handles the registration, treatment and publication processes for patents and supplementary protection certificates.
Currently, some updates are spread over consecutive nights due to the large, weekly volume of data concerning European patents designating Belgium.
For a European patent it is possible that data about the inventor(s) are missing from the online Belgian patent register. They can be found via the link to the European patent register pending an update of the Belgian patent register.
For European patents with Unitary Effect, the authentic source of information is the European Patent Register : please refer to it.
