The Essentiality Test – Falling Out of Favour at the EPO?

Author: Katherine Banks Ph.D.
Editor:  Hazel Ford Ph.D.

The European Patent Office (EPO) has a notoriously strict approach when considering amendments to patent applications.  If an amendment extends the subject matter beyond the content of the application as filed, then the amendment is unallowable under Article 123(2) EPC.  This is assessed based on the “gold standard” test, which examines whether the skilled person would regard the amended subject-matter to be directly and unambiguously derivable from the application as originally filed.  Continue reading

The Unitary Patent System (UPS) and the Unified Patent Court (UPC) are on the horizon. Expected to come into force in 2017, this will be the biggest change for 40 years in European patent practice and will directly affect all current and future European patents and applications.

The European Patent Office (EPO) is responsible for the examination and grant of ‘classical’ European patents under the European Patent Convention (EPC). A classical European patent acts as a ‘bundle’ of national patents, which are locally enforceable by the Courts of a contracting state, subject to validation in that state.
