4.1 Formal requirements
You can designate the inventor(s) in the tools provided by the EPO for online filing. Another option is to fill in and file the "Designation of inventor" form (EPO Form 1002) available on the EPO website (epo.org).
4.1.016If you do not designate the inventor when you file the European patent application, you will be invited to correct this deficiency within sixteen months after the date of filing or, if priority is claimed, the earliest priority date, and in any event no later than five weeks prior to the intended date of publication of the application (see point 5.3.001). If you fail to submit the designation of inventor within the specified period, your application will be refused (see point 5.2.005).
