Course overview

This seminar combines one day of claim drafting fundamentals with a further day of focused workshops. Attendees have the choice of either a mechanical or chemical workshop.

Key topics to be covered:

  • Patentable inventions
  • Prior art and inventive step
  • Sufficiency of disclosure
  • The importance of achieving adequate protection
  • The description and drawings
  • Selection inventions (chemical workshop)
  • Functional claiming (mechanical workshop)

Why you should attend

It is crucial to understand the fundamentals and the intricacies of European claim drafting so you are equipped to prove patent infringement and patent validity, especially in multi-jurisdictional patent litigation.

These intensive two days will help you refine your drafting skills and master the art of successfully preparing and defending claims according to European practice. You will learn the techniques to achieve adequate protection while meeting official requirements and analyse the crucial aspects of good description, amendments and interpretation to give you the edge in claims drafting.

The in-depth chemical and mechanical workshops will give you the opportunity to apply the knowledge learnt on day one and practise the skills acquired in the safe environment of the training room. There will also be ample opportunity for you to ask the experts your particular questions and find solutions to your specific claim drafting issues.

Ali Almulla, Director of Innovation & Invention Support Directorate, The Cooperation Council for the Arab States of the Gulf _ GCCPO, Nov 19

The speakers were both very passionate and knowledgeable about the subject and provided some good insights and personal reflections on the course material. The content of the course was excellent, and the second day (mechanical workshop) was particularly good because learning by doing is more beneficial for my learning process.

Emil Tostrup, Patent Consultant, Ström & Gulliksson, Nov 19

Professional speakers coming from two different technical fields gave valuable insights on how to structure claims. The best part of the course was practising claim drafting and learning how to better build suitable claims.

Nastasia Andersson, Patent Consultant, Ström & Gulliksson, Nov 19

The course was excellent: the content and the speakers. I will be sure to recommend it.

Mariana Oliveira, Technological Scouting / Patent Attorney, The Navigator Company, Nov 19

The course is really well prepared and presented and the speaker makes it easy to understand everything.

Cristina Rojo Matey, Patent Attorney Trainee, NLO, Nov 18

I thought it was a brilliant course that I would recommend to others. It was really good that there were so few people so one could ask all the "stupid" beginners' questions in a closed forum.

Vibeke Bay, Patent Attorney, Høiberg, Nov 18

The course is well organised, the speaker (Joeri) is excellent, competent, clear, patient and available to answer all our questions. The practical workshop was really useful. Overall opinion: excellent course.
