Weyerhaeuser Company (Weyerhaeuser) (defendant) was a firm in the business of manufacturing and selling hardwood lumber. From 1990 to 2000, Weyerhaeuser invested more than $75,000,000 into its lumber operations in the Pacific Northwest. Due to the investment and the increased production capacity, Weyerhaeuser’s need for logs increased. From 1998 to 2001, the price of logs increased, while the price of the hardwood lumber made from the logs decreased. Ross-Simmons Lumber Company, Inc. (Ross-Simmons) (plaintiff) was one of Weyerhaeuser’s competitors in the market for hardwood lumber. After the price of logs increased and the price of lumber decreased, Ross-Simmons incurred heavy losses and had to shut down its operations in 2001. Eventually, Ross-Simmons brought a complaint against Weyerhaeuser, alleging that Weyerhaeuser had engaged in an unlawful predatory-bidding practice to force Ross-Simmons out of business. In district court, a jury returned a verdict for Ross-Simmons. Weyerhaeuser appealed the decision, but the court of appeals affirmed. Weyerhaeuser appealed.
