Broad Institute Gets Patent on Revolutionary Gene-Editing Method

The Harvard-MIT genomic science institute stays mute on how it will assert control over the tools expected to speed cures and change gene therapy.

One of the most important genetic technologies developed in recent years is now patented, and researchers are wondering what they will and wont be allowed to do with the powerful method for editing the genome.

On Tuesday, the Broad Institute of MIT and Harvard announced that it had been granted a patent covering the components and methodology for CRISPRa new way of making precise, targeted changes to the genome of a cell or an organism. CRISPR could revolutionize biomedical research by giving scientists a more efficient way of re-creating disease-related mutations in lab animals and cultured cells; it may also yield an unprecedented way of treating disease (see Genome Surgery).

The patent, issued just six months after its application was filed, covers a modified version of the CRISPR-Cas9 system found naturally in bacteria, which microbes use to defend themselves against viruses. The patent also covers methods for designing and using CRISPRs molecular components.

The inventor listed on the patent is Feng Zhang, an MIT researcher and core faculty member of the Broad. Zhang was an MIT Technology Review Innovator Under 35 in 2013.

The patent describes how the tools could be used to treat diseases, and lists many specific conditions from epilepsy, to Huntingtons, to autism, and macular degeneration. One of the most exciting possibilities for CRISPR is its potential to treat genetic disorders by directly correcting mutations on a patients chromosomes. That would enable doctors to treat diseases that cannot be addressed by more traditional methods, a goal already set by a startup cofounded by Zhang called Editas Medicine (see New Genome-Editing Method Could Make Gene Therapy More Precise and Effective).

Another founder of Editas, Jennifer Doudna, and her institute, the University of California, have a pending patent application for CRISPR technology. How that west coast application will be affected is not yet clear. Its also unclear what impact the Broads claims on the technology will have on its commercial use and on basic research.

Chelsea Loughran, an intellectual property litigation lawyer who has been following CRISPR over the last year, says that lots of people are already using CRISPR and its not clear if it will now become harder for them to do that. All of that is in the hands of MIT and the Broad, she says.

While MIT, Harvard, and the Broad all jointly own the CRISPR patents announced yesterday, the Broads technology licensing office is managing decisions about who will get licenses to use the technology, says Lita Nelsen, director of the MIT Technology Licensing Office. (Licenses areformal permissions to use a patented technology, often in exchange for money.)

A spokesperson for the Broad says that specific details around licensing arent available at this time, but the Broad does intend to make this technology broadly available to scientists.
