The CRISPR patent battle is back on as UC Berkeley files an appeal

The University of California Berkeley has filed an appeal in a heated CRISPR patent interference case that ruled in the Broad Institute of MIT and Harvard’s favor last earlier this year.

Last year, the U.S. Patent Office started looking into whether or not the Broad Institute had the right to a separate patent for CRISPR-Cas9, which allowed for human use of the technology. Berkeley countered its patent was broad enough to cover all use of the technology and that the Broad should not have the right to a seperately filed patent.

The court ruled no interference in the case, meaning the the U.S. Patent Trial and Appeal Board (PTAB) decided co-discoverers of the technology Jennifer Doudna and Emmanuelle Charpentier had first successfully demonstrated the technology. However, the Broad Institute had the right to the patent for human use.

At the time, CRISPR pioneer and Berkeley professor Jennifer Doudna told TechCrunch the ruling was a positive as it didn’t throw out her claim that her patent should be able to cover all cells.

However, the Broad Institute would have a clear advantage in human use. The patent ruling also left a lot of confusion for companies wanting to apply the technology. It was unclear which institution to get permission from or which to make a deal with for various applications.

UC Berkeley has now filed with the U.S. Court of Appeals for the Federal Circuit in Washington, DC, to appeal the court’s decision that the Broad Institute should have the rights to the separate patent.

According to UC Berkeley, the decision took “a narrow and restrictive approach that ignored certain key evidence,” concluding conventional techniques would not guarantee success. UC Berkeley argues its invention would work in bacterial gene-editing of eukyrotic cells and that this was a natural leap.

It further argues  PTAB had ignored evidence that six other labs had quickly achieved eukaryotic editing using the information provided by a 2012 Science paper using Doudna and Charpentier’s work before the Broad had filed its separate patent.

“The PTAB’s ruling flies in the face of core legal principles that govern the interference-in-fact inquiry, and defies common sense,”  the UC brief states. “If uncorrected, that ruling threatens to allow Broad to arrogate to itself much of UC’s transformational invention without Broad demonstrating anything close to the genuine innovation that would justify finding its claims to be separately patentable. This Court should not let such a profoundly erroneous and unjust result stand.”

We’ve reached out to the Broad Institute but have so far not heard back. We’ll be sure to update this article if and when it does respond to us about the appeal.
