FAQ - web-form filing

General information

What is web-form filing?

A secure EPO web-based service that allows you to submit documents relating to the patent grant process with the EPO.

Who can use web-form filing?

Anyone can use it, so long as they register for the service. To register, you must provide a valid email address.

What document types can I file using web-form filing?

Only documents in PDF can be filed via the web-form filing service. The PDF should comply with WIPO's Annex F standard for e-filing.

To guarantee compliance, you should ensure that your PDF generator and resulting PDFs meet the following criteria:

  • All fonts are embedded (exception: Base 14 fonts are accepted even if they are not embedded).
  • The page size is A4.
  • The PDF is not encrypted.
  • The PDF does not contain colour or greyscale images or drawings.
  • The PDF is version 1.1 (or later).
  • The PDF does not contain embedded OLE objects.

If you are generating PDFs from paper documents using your scanner you should adjust the settings of your scanner accordingly.

The EPO offers free-of-charge access to a version of Amyuni PDF Converter which is preconfigured to produce PDF documents that can be transmitted with web-form filing.

Unitary Patent: transitional measures

When and for which European patents can a Unitary Patent be requested?

A Unitary Patent may be requested for any European patent granted on or after the date of application of Regulations (EU) No 1257/2012 and (EU) No 1260/2012. These two regulations will apply from the date of entry into force of the Agreement on a Unified Patent Court (UPCA). The EPO will announce this date on its website.

When the request for unitary effect is finalised, Online Filing 2.0 (OLF 2.0) generates an XML file. Is it possible to automatically upload an XML with the required information?

Neither Online Filing (OLF) nor OLF 2.0 supports XML filings (i.e. attaching the form as an XML). However, the systems support the importing of packages. Therefore, if the package is constructed with a Patent Management System (PMS) gateway and it meets the standards and requirements, it can be imported into OLF and OLF 2.0.

The EPO will provide the technical documentation on the PMS gateway in good time at epo.org/applying/online-services/online-filing/interface.html.
