Sashco, Inc. v. Red Devil, Inc., No. 1:88-CV-01639 (D. Colo. Oct. 11, 1988). This was a Patent infringement litigation involving Sashco’s U.S. Patents 4,776,458 and 4,863,014, for clear caulk cartridges and tubes. Mr. Aitken participated in an evidentiary hearing where the Colorado court found that Red Devil had not violated a previous consent decree. Subsequently, on Red Devil’s summary judgment motion for non-infringement, the court found that Red Devil did not infringe Sashco’s patents. Mr. Aitken represented Red Devil as co-counsel.
