A New Frontier for Added Subject-Matter at the EPO?
At the European Patent Office (EPO), a recent referral of case T 873/24 from the Technical Board to the Enlarged Board of Appeal may clarify whether last summer’s decision in case G 1/24 on claim interpretation may be extended to the analysis of Added Subject-Matter. Already G 1/24 is impacting the assessment of patentability at the EPO, but should this referral be allowed, G 1/24’s effect on the assessment of added matter could result in a real shake up of the EPO’s notoriously strict assessment of support. Nonetheless, a review of how we got here highlights the value of late arguments during the EPO appeal process.
