Woods v. DeAngelo Marine Exhaust, Inc., No. 10-1478 (Fed. Cir. 2012)
Annotate this CaseWater jacketed marine exhaust systems cool exhaust as it exits the engine of a marine vessel. These devices generally consist of two cylinders with exhaust flowing through the inner cylinder and water flowing through the space between the inner and outer cylinders. Woods exclusively licensed his 670 and 633 patents to MES. Sometime before 2006 MES became aware that DeAngelo was selling exhaust systems that were believed to infringe the Woods patents and filed suit. The district court ruled in favor of MES. The Federal Circuit affirmed, upholding exclusion of engineering drawings as an untimely interrogatory supplement despite DeAngelo’s identification of the drawings immediately upon finding them and on the final day of the scheduled discovery period. The court also upheld the district court's claim construction and rejection of claims of obviousness.
