How can I provide the supporting documents to the EPO?

In principle, you must submit together with the PPH request paper copies of all documents listed in FAQ ‘What are “supporting documents”?’.

 

If the application is published and the documents are available via the respective Dossier Access System (DAS) or Patentscope, you may request that the EPO retrieves these documents electronically. In this case, you must submit a list of the documents to be retrieved.

You also need to submit a list of all documents other than patent documents (i.e. non-patent documents) cited in the OEE work product(s).
