Course overview

Many patent applications and patents are lost before the EPO, either before Opposition Divisions or before Appeal. Attending this course will enable you to avoid incorrect original drafting and added subject matter which are recurrent problems in this area.

Amendments made during the grant procedure to incorporate new prior art amount to added subject matter, which is often fatal in opposition procedure before the EPO, and in nullity proceedings before national courts. Sufficiency of disclosure can also be a problem and if initial disclosure is insufficient, amending it can amount to adding subject matter.

The purpose of this seminar is to identify the problems of added subject matter and sufficiency of disclosure and show how they can be easily avoided by careful drafting.

The expert trainer will take you through how to deal effectively with these challenges and ensure you understand how to avoid potential problems with amendments so your patent applications are successful.

The key topics covered include:

Article 123(2) – identify and deal effectively with added subject matter
How to avoid problems with amendments
Article 83 – the importance of sufficiency of disclosure

This course is part of our collection of IP & Patents Training Courses.
