In other words, the PTAB ruled that the two parties’ claims were separately patentable.

But in a statement from the Broad, Chief Communications Officer Lee McGuire expressed confidence in the institute’s existing CRISPR patent. “Given that the facts have not changed, we expect the outcome will once again be the same,” he said. “To overturn the PTAB decision, the Court would need to decide that the PTAB ...
