CELLECTIS SA Terminates genOway’s License under its Homologous Recombination Technology


1/5/2009 11:56:11 AM

Biocitech, Romainville, January the 5th 2009 – Cellectis S.A. (NYSE – Euronext: ALCLS), the genome engineering company, announces having terminated the non-exclusive license it had granted to Genoway S.A. in 2001 for certain uses of homologous recombination. The termination is effective as of December the 30th 2008.

The license was granted under patents: FR2646438, EP419621, EP682112, US6528313, US6638768, US6528314, JP3059481, JP3298842, JP3298864, SG49110 and SG49112, and authorized making and selling cellular and animal models in a restricted field, for research uses only expressly excluding the use of such product for any commercial application.

Genoway S.A. challenged this termination in court. Cellectis intends to obtain proper compensation for the damages that it deems having suffered from the uses made by Genoway S.A. outside the licensed field.

About the licensed patents

The license granted rights under a patent family deriving from the original FR8903630 filing dating back to 1989. This family includes patents: FR2646438, EP419621, EP682112, US6528313, US6638768, US6528314, JP3059481, JP3298842, JP3298864, SG49110 and SG49112. The last patents to expire in that family will expire in 2020 in the USA. Institut Pasteur granted Cellectis with the exclusive worldwide rights over this patent family.

These patents cover certain uses of homologous recombination (also referred to as “gene targeting”), in particular for the targeted insertion of DNA sequences made functional in eukaryotic genomes, such as that of animals for example. The “knock-in” processes, currently used to obtain cellular and animal models, including mouse models, such as mice that are “humanized” for a chosen gene, are covered by these patents, which use bring significant benefits to the pharmaceutical and biotechnology industries for the understanding of biological mechanisms as well as for drug development.
