Weil recently achieved a victory for client BASF in three Patent Office Inter Partes Review proceedings related to technology for reducing emissions from diesel exhaust.
In May 2015, Johnson Matthey, Inc. filed petitions seeking to have the Patent Office review three BASF patents relating to a diesel exhaust filter that simultaneously removes particulate matter and nitrogen oxide from diesel exhaust. The BASF technology allows the automotive industry to meet increasingly stringent emissions standards implemented by governments throughout the world.
Despite a preliminary finding that Johnson Matthey had presented prior art that was likely to render the BASF patents invalid, after a full IPR hearing and trial, Weil ultimately convinced the Patent Office that all of the challenged claims in the BASF patents were patentable.
