Electronic submissions may be filed with the HIPO only by using the free-of-charge form provided for this purpose. The form can be accessed by clicking the Start Administration button.
In proceedings before the HIPO, electronic communication is possible only in a manner linked to identification, except for requests for information and their execution, as well as international patent cases.
Identification can be done in the following ways:
User identification system created by the HIPO, based on a one-time re-identification with the Central Authentication Agent.
Electronic signature with enhanced security is a minimum requirement.
When turning to the HIPO after identification through a partner card or the Central Authentication Agent, the HIPO will send its decisions, notifications and other calls made during the procedure to the client’s official electronic storage space.
It is important to emphasize that in case of identification with an electronic signature, the HIPO cannot communicate with its clients electronically and can deliver its decisions only on paper.
The filing procedure is as follows:
1. Download the form to your device. Filling out the form in a web browser is not recommended.
2. Login to the electronic administration system of the HIPO by using the Central Authorization Agent, partner card or electronic signature. If you have an electronic signature, please choose identification using an electronic signature with enhanced security.
3. Upload the filled form into the system. Based on the attachments marked in the form, a table will appear in which the attachments must be uploaded one by one. If you have already compiled these into a directory, you will easily find the right documents.
The size of files that can be attached to forms cannot exceed 150 MB each. The total size of the submission and all attachments may not exceed 300MB.
4. Indicate that you really intended to compile this submission, or look at the HTML submission summary.
The system compiles your submission, encrypts it and sends it to HIPO. HIPO sends an automatic notification about the arrival of the submission.
