Opportunities and challenges for user-generated licensing models in gene-editing

A voluntary pool or clearinghouse model may give rise to a robust commercial ecosystem for CRISPR and could include special provisions for royalty-free research use by academics. Hence, there may be a path through the CRISPR patent jungle. But, there are many obstacles still in the way.

The revocation of Broad Institute’s patent EP2771468 reported and discussed here, marks the latest major development in a series of patent battles over the revolutionary and highly lucrative CRISPR-Cas9 technology (and other gene editing technologies) in the US and Europe.

While this is the first EPO decision in an opposition procedure concerning the Broad patent portfolio, the outcome may have implications for other related patents as the rationale for the revocation reflects a larger, systemic challenge based on the different rules regarding priority claims in different jurisdictions.

Will the EPO’s Enlarged Board of Appeal step into the CRISPR patent battle?

By  Jakob Wested, Timo Minssen & Esther van Zimmeren

Another version of this contribution has been published in Life Science Intellectual Property Review (LSIPR).

The Broad Institute is facing a formidable task in defending the revoked CRISPR patent claims in their pending appeal at the European Patent Office (EPO). Ultimately, some of the issues might still be referred to the Enlarged Board of Appeal. However, this might require a significant amount of legal and rhetorical agility.

“The Opposition Division’s interpretation of the EPC [European Patent Convention] is inconsistent with treaties designed to harmonize the international patent process, including that of the United States and Europe.”

This was the rather strong reaction of the Broad Institute after the EPO’s Opposition Division’s (OD) decision to revoke one of their CRISPR patents. It could, however, also be argued that the case presents a simple failure of the patent applicants to comply with the long-standing European practice to apply an “all applicants” approach when claiming priority under article 87 of the European Patent Convention.
