Precision BioSciences Files Patent Infringement Lawsuit Against Cellectis Related to Gene Editing Technology

RESEARCH TRIANGLE PARK, N.C.--(BUSINESS WIRE)--

Precision BioSciences, Inc., a leader in the field of genome engineering, today announced that it has filed a patent infringement lawsuit against Cellectis SA (ALCLS) and a number of its affiliates in the U.S. District Court for the Eastern District of North Carolina. The lawsuit seeks a ruling that Cellectis' manufacture, use, sale, and importation of certain engineered meganucleases infringe U.S. Patent No. 8,304,222 (the “‘222 patent”), which relates to Precision BioSciences' Directed Nuclease EditorTM genome editing technology. The lawsuit requests monetary damages as well as a permanent injunction preventing Cellectis from making, using, selling, offering for sale, or importing infringing engineered meganucleases in the United States. Precision BioSciences previously announced that it had filed suit against Cellectis for alleged infringement of U.S. Patent Nos. 8,021,867, 8,119,381, 8,119,361, 8,124,369, 8,129,134, 8,133,697, 8,143,015, 8,143,016, 8,148,098, and 8,163,514.

Among the engineered meganucleases that Precision believes infringe the ‘222 patent and numerous other Precision-controlled patents is one that is referred to as CLS4617 in a paper by Certo et al. published in Nature Methods (September 2012). The authors of this paper, which include a number of Cellectis employees, report that the CLS4617 meganuclease is being used in the United States to target and cleave a DNA sequence in the human CCR5 gene.

“Cellectis' continued disregard for Precision's foundational gene editing patent estate will not be tolerated,” said Matthew Kane, CEO of Precision BioSciences. “Precision expects all competitors, domestic and foreign, to obey United States law and to refrain from illegal use of our proprietary technology.”
