UC granted a key CRISPR patent

However, its legal fight with Boston’s Broad Institute over rights to use the powerful gene-editing tool in plant and animal cells continues

The University of California has scored a victory in the multifront­ed war for rights to CRISPRCas9 technology, a powerful tool for editing genomes.

On Tuesday, the U.S. Patent and Trademark Office granted UC a patent covering the use of CRISPR-Cas9 for editing genome regions of 10 to 15 nucleotide­s long. Nucleotide­s are the 3 billion letters that write the genome’s book of life.

Last week, the government granted a less significan­t patent to UC, covering use of CRISPR-Cas9 to edit genetic material called single-stranded RNA.

Tuesday’s decision “is one of many we anticipate will be awarded to these inventors for their CRISPR-Cas9 invention,” said Dr. Edward Penhoet, special advisor to the chancellor at UC Berkeley and special assistant to the University of California president.

UC sees a number of potential applicatio­ns in research, diagnostic­s, and industry for their new CRISPR patent.

But some experts see it differentl­y. New York Law School Associate Professor Jacob Sherkow told the publicatio­n STAT that he ex-

pected the patents to have “pretty minimal” commercial value.

The CRISPR gene-editing tool gives scientists near godlike power: moving genes from one living creature to another. In a mere five years, it has transforme­d research into plant and animal breeding. Research is also progressin­g in efforts to cure hereditary disease and combat infectious disease and cancer.

Meanwhile, UC continues its bitter legal fight with Boston’s Broad Institute over U.S. rights to CRISPR use in plant and animal cells — a broader and arguably the most valuable patent. Tuesday’s patent is not one of those involved in that proceeding.

UC is appealing a patent office decision that Broad can keep its key CRISPR patents. If UC loses again, that’s it; a Supreme Court appeal is considered highly unlikely, according to Sharon Begley of STAT, a national science news publicatio­n. Neutral observers think a

resolution — any resolution — is what’s needed to get serious settlement talks going and maybe create a patent pool, she said.

But patents for the wide use of CRISPR-Cas9 for gene editing all types of cells have already been issued to the Jennifer Doudna-Emmanuelle Charpentie­r team by the European Patent Office, representi­ng more than 30 countries, as well as the United Kingdom, China, Japan, Australia, New Zealand and Mexico.

CRISPR’s scientific breakthrou­gh — with the potential to cure countless genetic

disorders from sickle cell anemia to cystic fibrosis — was devised in 2012 by UC Berkeley cell biologist Doudna and her European collaborat­or Charpentie­r. It was improved upon by Broad Institute’s Feng Zhang.

“Their remarkable research has only accelerate­d since then creating new jobs and opening up new possibilit­ies to improve life,” said Penhoet.

CRISPR research is a large field that involves contributi­ons from many talented scientists around the world — so many CRISPR patents are out there, each different enough to be considered a unique invention. A patent gives an inventor ownership of their discovery. If anyone else wants commercial use of it, they have to pay to license that right.

The US Patent and Trademark Office has issued more than 60 patents with claims to CRISPR to approximat­ely 100 inventors from 18 applicant organizati­ons, according to the Broad Institute.

The European Patent Office has issued more than 20 such patents to approximat­ely 30 inventors from about 10 applicant institutio­ns.
