Cellectis Sues Precision BioSciences for Infringement of its Patents Concerning Meganuclease Technology

March 13, 2008 /PRNewswire-FirstCall/ -- Cellectis SA , a world leader in rational genome engineering, has announced today that it filed a patent infringement lawsuit against Precision BioSciences, Inc. in the United States District Court for the Eastern District of North Carolina. The lawsuit seeks a declaration that, by making and selling certain meganucleases, Precision BioSciences infringes two Cellectis patents relating to its proprietary meganuclease recombination systems. The Precision Biosciences' meganucleases at issue are intended to target site-specific DNA breaks and effect a desired genome modification in a given transgenic organism, such as a plant. The lawsuit seeks both monetary damages for infringement, as well as a permanent injunction preventing Precision BioSciences from any further making, using or selling of such meganucleases. "We take our intellectual property rights very seriously and intend to vigorously pursue this patent infringement case," said Dr. Andre Choulika, CEO and co-founder of Cellectis SA., and the man who participated in coining the term "meganuclease."

Since its creation in January 2000 and throughout its development, Cellectis has made special efforts to protect new discoveries made by its research team as well as those of its partner, the world-renowned Institut Pasteur. Cellectis currently owns the exclusive rights to over 35 issued patents and 113 pending patent applications. Most of these patents are based on Cellectis' fully integrated genome engineering system referred to as its Meganuclease Recombination Systems (MRSs). These systems offer natural, efficient, precise and flexible genome surgery with several applications, among others, in the therapeutic area and in the plant science field.
