The invention application documents shall be submitted in docx format and comprise a description of the invention, at least one patent claim, drawings, if they are part of the documentation, and annotations –see item 1.2 Instructions from the President of the Industrial Property Office. The same applies to the documents of the utility model application.

The Industrial Property Office announces that from Monday, 19 March 2018 at 0:00 a.m., the variable symbol for the payment of administrative fees for European patents has changed. The variable symbol will now consist of the number 2 and the number of the European Patent, which is the same as the publication number of the European patent application, publication No. (e.g. EP 1 444 521 has VS 21444521). From that date, the automatic payment pairing system will assume the use of a variable symbol in this new form.

This amendment only applies to EP administrative fees (paid to account 3711-21526001/0710), not EP maintenance fees.
