How can I submit observations about a published application or granted patent?

By post or online:

• using the EPO's online form,
• via MyEPO,
• via the European Patent Register.

If the online form is not working you can always file your observations using Form 1038 in Online Filing 2.0 or by post.

Here is the EPO's Munich postal address:
