Solast week the feds may have dashedUC Berkeleys billion-dollar dreams when it decided not to give the universitypatent rights over CRISPR-Cas9, a revolutionary gene-editing technology. <\/p>\n
The Feb. 15ruling from the U.S. Patent and Trademark Office let Berkeleys rivaltheBroad Institutejointly owned by Harvard and MITkeep itsexisting patents issued in 2014.UC Berkeleyhas yet to say whether or not it will appeal. <\/p>\n
Berkeley was seeking to have some of those patents repealedbecause the university says they conflict with its pending patent application for CRISPR. <\/p>\n
The judges reasoned that Berkeleys patent request doesnt affect Broads existing patents because the two are based on different gene editing techniques. <\/p>\n
Berkeleys patent request is for editing genes in bacteria, whereas Broads existing patents are for editing genes in eukaryotic cells, i.e. cells found in plants and animals, including humans. <\/p>\n
But Berkeleyargues that its research toolcan easily be extended to use in non-bacterial cells. <\/p>\n
That distinction is key since potentially lucrative applications of gene editing in medicine and health will involve eukaryotic cells found in humans. <\/p>\n
UC Berkeley biologist Jennifer Doudna, who is credited with co-inventingCRISPR-Cas9 now has two options: <\/p>\n
1) Appeal to the U.S. Court of Appeals for the Federal Circuit 2) Go back to the U.S. Patent and Trademark Office <\/p>\n
If Berkeley appeals, the court could overrule the patent office decision in favor of Berkeley. <\/p>\n
If Berkeley loses, it could go backto the patent office, where itcould be required to narrow itsclaims, i.e., specifying that its technique is only intended to be used in bacteria. <\/p>\n
Or it could get a broad patentthat still doesnt specifyhow to use CRISPRin eukaryotic cells. But according to Jacob Sherkow, a law professor at New York Law School, that could lead to future legal challenges. <\/p>\n
Its not going to be that strong because anyone who wants to challenge it later can say, that patent doesnt disclose how to use the tool in eukaryotic cells,' says Sherkow. <\/p>\n
And the money is in altering those specific cells. <\/p>\n
So whats next? Only Berkeley knows; the university has said it will carefully consider all options. <\/p>\n
Science journalists are abuzz about what this means for biotech. Heres a sampling of what theyre saying: <\/p>\n
1.Berkeley + Broad = VirtualMonopoly on CRISPR-Cas9 (Gizmodo) <\/p>\n
Why does this matter? While academic researchers can still use CRISPR for free, companies hoping to harness the gene editing tool to fight disease, solve agricultural problems, or for myriad other potential applications, may have to pay not one, but both institutions, a hefty fee. Its a decision that has caused some to wonder whether the rights to such revolutionary technology dont really belong to a third party: the people. <\/p>\n
2. Could the Case Encourage Scientiststo Be Less Honest?(STAT) <\/p>\n
The patent judges concluded that the inventors themselves were uncertain about making CRISPR work in human cells. <\/p>\n
That could send a terrible message to scientists, said Dr. Robert Cook-Deegan of Arizona State University, an expert on legal and ethical issues surrounding biotechnology. I hope this does not become the poster child that patent offices use to coach scientists not to be honest about uncertainties about their discoveries, he said. The fact that Doudnas quotes were used by the judges mainly tells me Doudna was being honest. I hope scientists will continue to be honest and not succumb to being told they cant say things that might undermine a broad patenting strategy. <\/p>\n
3. Fogettaboutit, Companies Can SidestepBerkeleyand Broad(Nature) <\/p>\n
Researchers in academia and industry have been pushing CRISPR gene editing beyond the scope of the Broad and Berkeley patents. <\/p>\n
Both patent families cover the use of CRISPRCas9, which relies on the Cas9 enzyme to cut DNA. But there are alternatives to Cas9 that provide other functions, and a way to sidestep the BerkeleyBroad patent fight. <\/p>\n
One attractive alternative is Cpf1, an enzyme that may be simpler to use and more accurate than Cas9 in some cases. The Broad has already filed patents on applications of Cpf1 in gene editing, and has licensed them to biotech company Editas Medicine in Cambridge, Massachusetts. <\/p>\n
Remember, my friends, if UC Berkeley appeals, this whole process could last through 2020. Or longer. <\/p>\n
