Syngenta Wins Azoxystrobin Patent Infringement Case

A U.S. District Court has permanently enjoined Willowood USA from importing into the United States, or making, using, selling, or offering for sale in the United States, any azoxystrobin or end-use products containing azoxystrobin made using a process that infringes Syngenta’s ‘761 patent.

The jury had previously found that Willowood’s azoxystrobin fungicide products are manufactured using azoxystrobin made by a process protected by Syngenta’s valid U.S. Patent No. 8,124,761. Syngenta’s ‘761 patent does not expire until April 15, 2029.


The Court further concluded that Willowood should not be allowed to use the azoxystrobin previously imported to manufacture fungicide products or to sell any such fungicide products, as such actions would constitute new acts of infringement causing new and additional damages not taken into account by the jury’s verdict.
