Working language(s)



This self-paced training course defines a learning path through the basics about Clarity and Unity of invention, with an emphasis on practical examples. Because both topics require a case-based approach, the learning path guides the user through the different topics and proposes exercises having a different degree of difficulty.

During the course participants will work on an assignment. Certificates will only be issued to participants who have completed and submitted it by the indicated deadline.


•    Clarity
•    Unity of invention
•    Search and Examination of patent applications

Target groups

Staff of national offices of EPO member states.

Level of expertise



Online training


Once successfully completed, participants will be able to effectively apply the criteria for Clarity as well as the methodology for determining the Unity of invention in line with the EPO practice (Guidelines and Case Law).


The distance learning course will explain in detail the background theory and methodologies with reference to Clarity and Unity of invention according to the EPC:
•    Clarity as in Art. 84 EPC
•    Relation of clarity with Art. 83 EPC
•    Unity of invention, Art. 82 EPC
•    Methodologies for determining the unity of invention
•    Practical exercises with different degrees of difficulty


A balanced mix of theory and practice, providing for interactive discussions by means of webinars and an online forum will help to generate new knowledge, clarify open questions and allow for immediately putting into practice the acquired know-how.


Participants should have a minimum of one year experience of searching or examining patent applications. A good command of spoken and written English is required.
