BASF Agro B.V., Arnhem (NL), Wadenswil Branch v. Makhteshim Agan of North America, Inc., No. 2012-1206 (Fed. Cir. Mar. 20, 2013)
BASF Agro B.V. (“BASF”), the world’s largest chemical manufacturer, suffered a setback in its patent litigation against Makhteshim Agan of North America (“Makhteshim”), the world’s largest generic agrochemical maker.The Court of Appeals for the Federal Circuit affirmed the Middle District of North Carolina’s grant of summary judgment of non-infringement for the defendants. The suit focuses on patents covering BASF’s termite-killing pesticide, Termidor, which is the United States’ top-selling pesticide. BASF commenced litigation in 2010 after Makhteshim began selling a competing product, Taurus SC.
The Federal Circuit affirmed the lower court’s claim construction, which was largely based on the doctrine of prosecution disclaimer, as applied to BASF’s actions during patent prosecution. Under that claim construction, the issue of non-infringement was easily decided as a matter of law; thus, summary judgment of non-infringement for the defendants was appropriate. Specifically, the court found that BASF had disclaimed so-called “barrier” techniques of pesticide application—which aim to surround buildings with a complete polygon of pesticide—in favor of deploying pesticide at discrete locations around the building boundary. Since Makhteshim’s products use the polygonal barrier method, they did not infringe BASF’s patents.
