Pennzoil-Quaker State and its subsidiary, Medo Industries, turned to Quinn Emanuel when petroleum giants Valvoline and Ashland, and the inventors of the two patents at issue, sued for patent infringement for after-market car products. At the hearing on cross-motions for summary judgment, the firm used a 165-slide PowerPoint presentation to explain to the court why, in light of the claim construction and file histories, the accused products did not infringe. The court adopted the firm’s argument and granted summary judgment of non-infringement to Pennzoil-Quaker State.
