Effective Defence of European (EPO) Patent Applications

The «problem-solution» approach
Dominobrikker faller
Clarity in drafting patent claims is required to distinguish the subject matter of a claim from prior art. An unclear claim can be interpreted to the disadvantage of the applicant or proprietor. This is not just a formal matter, but a substantial issue of the highest importance.

The "problem-solution" approach is not officially part of the EPC, but is a criterion which has been developed by case law. It is now hard to find a decision of the Boards of Appeal which does not rely on the problem-solution approach when deciding inventive step. It looks easy, but when applied, it should be applied correctly. 

Central topics include:

  • Article 84 – the implications of clarity of claims 
  • Effective use of the problem-solution approach 
  • Article 56 – understanding inventive step 

The purpose of this seminar is to enable participants to understand the essentials of clarity and the most effective use of the problem-solution approach, giving them an edge over other parties.

For whom?

This seminar is suitable for European patent attorneys, patent attorneys in private practice, corporate patent attorneys and lawyers, EQE candidates, and others working regularly with intellectual property. 

In cooperation with Management Forum
