Editas Medicine Announces Favorable Decision from the U.S. Patent and Trademark Office in CRISPR Patent Interference

Editas Medicine, Inc.

CAMBRIDGE, Mass., Feb. 28 10, 2022 (GLOBE NEWSWIRE) — Editas Medicine, Inc. (Nasdaq: EDIT), a leading genome editing company, today announced that the United States Patent and Trademark Office (USPTO) has issued another decision in favor of the Broad Institute, Inc. (Broad) involving specific patents for CRISPR/Cas9 editing in human cells. Pending an appeal in the Federal Circuit, this decision ends U.S. patent interference between the University of California, University of Vienna and Emmanuelle Charpentier (collectively, CVC) and Broad.

This action by the USPTO is the second favorable ruling establishing Broad as the first group to invent the use of CRISPR/Cas9 to edit DNA in cells needed to manufacture gene-editing drugs for humans. With this decision, the USPTO has clearly determined that CVC was not the first to invent the use of CRISPR/Cas9 in eukaryotic cells, including human cells, and that CVC is not entitled to claims of patent on this subject. The patents at issue in the current interference belong to Broad and are exclusively licensed to Editas Medicine for the development of drugs for people with serious illnesses.

“While scientists from both groups have made important scientific contributions to the field, this procedure aimed to determine who invented the use of CRISPR/Cas9 to edit DNA in eukaryotic cells, including human cells. We are pleased with the U.S. Patent and Trademark Office’s decision ending the interference and determining the Broad Institute’s innovative work to discover and use CRISPR/Cas9 technology in human cells,” said James C. Mullen, Chief Executive Officer, Officer, Editas Medicine “This decision reaffirms the strength of our core intellectual property as we continue our work developing life-changing medicines for people with serious illnesses. We use this breakthrough technology to develop drugs, including our flagship EDIT-101 program for the treatment of ACL10.”

Editas Medicine’s core intellectual property includes issued patents covering fundamental aspects of CRISPR/Cas9 and CRISPR/Cas12a gene editing. Editas Medicine’s patents broadly cover CRISPR/Cas9 and CRISPR/Cas12a gene editing in all human cells. Successfully modifying this cell type is critical to making CRISPR-based drugs. Overall, the Company holds a wide range of fundamental intellectual property covering all components of its genome editing platform as well as enabling and product-specific intellectual property. Patents covering the use of CRISPR/Cas9 and CRISPR/Cas12a for gene editing of human cells have been granted in the United States, Australia, Europe, Japan, China and other jurisdictions.
