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

The UC/Vienna/Charpentier team 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.

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 […]

The PTAB decides there is no interference-in-fact

After hearing motions from both parties, the Patent Trial and Appeal Board (PTAB) rules that there was no interference-in-fact. The board decides that the Broad’s claims to the use of CRISPR-Cas9 gene editing in eukaryotic cells are patentably distinct from the broader claims of the Doudna-Charpentier team. This decision terminates the interference at what is […]
