A US and EP Comparison on Added Subject Matter

All patent offices prohibit the addition of new matter. However, the EPO is unusually strict in this regard, and Applicants and Patentees can find themselves unable to amend claims in the way they wish to encompass key commercial products. In this webinar, we will look at key EP pitfalls such as “selection from lists,” “intermediate generalization,” and the dreaded “added matter trap,” and we will contrast these with current US practice.

Topics will include:

• An overview of added subject matter and evaluation guidelines in the United States and Europe
• Practical examples of dealing with added subject matter issues which may arise during patent prosecution
• Tips for preemptively preparing for added subject matter issues during the drafting stage in the United States and Europe
• Tips for instructing local counsel
