Course overview
Strong claim drafting is the cornerstone of effective patent protection. In European practice, understanding both the fundamentals and the subtleties of claim drafting is essential to secure adequate protection, defend validity and prove infringement - particularly in multi-jurisdictional litigation.
This intensive two-day training course will sharpen your drafting skills and equip you with the techniques needed to meet official requirements while achieving commercially meaningful protection. Through a detailed exploration of novelty, inventive step, clarity, claim scope, description, amendments and interpretation, you will gain practical insights into what makes a robust and defensible patent claim.
Day one delivers a comprehensive foundation in claim drafting, focusing on the principles, dos and don’ts, and the legal framework shaping European practice. Day two offers a choice of interactive mechanical or chemical workshops, where you will apply what you’ve learned in realistic drafting scenarios. These hands-on sessions provide a safe environment to practise, refine and troubleshoot your approach under expert guidance.
With a strong emphasis on practical application, this training course ensures you leave with the knowledge and confidence to draft, amend and defend patent claims effectively across jurisdictions.
During this thorough and well-structured training programme, the expert trainers use a mix of theory, examples, exercises and workshops to cover the fundamentals and advanced drafting issues and help embed the learning. Plus, ample time is built in for discussion, enabling you to address your specific challenges and benefit from the trainers’ expertise.
** This training course combines a full day of claim drafting fundamentals with a further day of focused workshops. Attendees have the choice to attend either a mechanical or chemical workshop on day two.
PLEASE NOTE:
Attendees will benefit from bringing a copy of the European Patent Convention with them.
