Sexing Technologies filed a lawsuit against Genus PLC in the U.S. District Court for the Western District of Wisconsin, alleging that the animal genetics company infringed on seven of its patents.
The litigation is part of the long-running dispute between both entities over a sexed semen technology that allows farmers to breed bovine calves of the desired sex.
Genus sued Sexing Technologies in 2014 for allegedly monopolizing the market for sexed bovine semen through anti-competitive practices. Sexing Technologies filed counterclaims, alleging breach of agreement and patent infringement.
Genus won a permanent injunction against Sexing Technologies in April, paving the way for the launch of its own sexed semen technology in 2017. The injunction bars Sexing Technologies from invoking certain contractual restrictions from a 2012 agreement between the companies.
In granting the injunction, the court agreed that Sexing Technologies willfully monopolized the market but also found Genus guilty of infringing on two patents.
Genus noted that it intends to vigorously defend against the lawsuit and that the litigation will not delay the launch of its sexed semen technology in 2017.
