Resolving an appropriate standard for what Is “material” information in patent prosecution

In a Federal Circuit appeal on behalf of client Digital Control, Inc. (DCI), Finnegan was able to obtain a reversal of the district court’s judgment. The reversal paved the way for a favorable settlement, and it also resolved an important issue on what is “material” information in prosecuting patent applications in the PTO. The patents at issue in the case were fundamental to DCI’s business and involved electronic locating equipment for horizontal drilling devices.
