Board of Appeal of the European Patent Office

Less than two months after CVC made the surprising move to revoke two of its seminal European CRISPR patents, Sigma-Aldrich has done it too. While the facts that led to Sigma’s “self” revocation may be different than CVC’s, this en vogue trend of avoiding final decisions is troubling because it denies the public of the certainty it deserves. 

There is no shortage of surprises and twists in the decade-long fight over the control of dominant IP in the CRISPR space.  The newest one is the self-revocation of two seminal CRISPR patents in Europe by the team led by two Nobel Laureates Emmanuelle Charpentier and Jennifer Doudna (aka “CVC”).
