U.S. Court of Appeals for the Federal Circuit hears oral arguments in appeal of PTAB ruling

CVC argued in the April 30, 2018 hearing before the U.S. Court of Appeals for the Federal Circuit (CAFC) that the PTAB incorrectly concluded that the use of CRISPR-Cas9 to edit eukaryotic cells was separately patentable from its use in other settings when it terminated the interference without deciding priority of invention. The appeal centers […]

Doudna-Charpentier team submits Appellant Brief to U.S. Court of Appeals for the Federal Circuit (CAFC)

This brief argues that the Patent Trial and Appeal Board (PTAB) used incorrect standards in assessing whether CRISPR-Cas9 genome editing in eukaryotes was an obvious extension of its core invention and the Jinek 2012 paper describing it. Specifically, it argues that previous court decisions, including by the U.S. Supreme Court, establish that the correct standard […]
