Expert e-Commerce GmbH v.Seoul Viosys Co., Ltd.
In a significant decision regarding patent scope, the UPC Board of Appeal invalidated key claims of EP 3 926 698. The core finding centered on the doctrine of impermissible expansion, holding that a claim cannot extend beyond what was clearly and unambiguously disclosed in the original application documents. This ruling reinforces strict interpretation requirements for divisional applications, emphasizing that the scope must be traceable to both the initial filing and the parent PCT application. For patent practitioners, this case serves as a strong reminder of the critical importance of precise drafting and disclosure during the prosecution phase.
expert klein GmbH v.Seoul Viosys Co., Ltd.
In this UPC appeal, expert klein GmbH successfully challenged the validity of EP 3 926 698 held by Seoul Viosys Co., Ltd. The court ruled that Claim 1 was invalid because it contained an impermissible extension of subject matter. Specifically, features not clearly and unambiguously disclosed in the original application or PCT filing were deemed outside the scope of protection. This decision reinforces strict interpretation principles regarding claim scope derived from initial patent disclosures, a critical point for IP strategy.
