PTAB Upholds Corteva's Patent For Insect-Repellent Corn

By Editorial Team

The Patent Trial and Appeal Board (PTAB) has recently upheld the patent held by Corteva Agriscience LLC for an insect-repellent corn plant. This decision comes after a challenge from Inari Agriculture Inc., where PTAB ruled in favor of Corteva's patent.

Corteva's patent, directed towards an insect-repellent corn plant, was challenged by Inari Agriculture Inc. However, PTAB's decision upheld the validity of the patent, providing Corteva with continued protection for their innovative technology.

The patent in question is identified as 8,901,378, titled "Corn event TC1507 and methods for detection thereof." This patent plays a crucial role in protecting Corteva's intellectual property related to insect-repellent corn plants.

Law firms involved in this case include Finnegan and Wolf Greenfield, representing the respective parties. Companies such as Corteva Inc., DuPont de Nemours Inc., Inari Agriculture Inc., and Pioneer Hi-Bred International Inc. were also part of this legal battle before the PTAB.

This decision by PTAB reaffirms Corteva's rights over their patented technology, ensuring that they can continue to innovate and protect their advancements in the field of agricultural biotechnology.
