Heading: Substantial Evidence Supports the Damages Determination

Text: 60 We conclude that ample evidence in the record supports the district court's determination of damages. The district court found that Professor Rubinfeld, an expert economist, ably addressed the amount of profits to be returned, performing an analysis that calculated the incremental profits, i.e., sales less production and marketing/distribution costs, of Cyanamid that were attributable to the right to exclude generic competition. Specifically, Professor Rubinfeld calculated Cyanamid's incremental profit in terms of Materna sales, from the issuance of the '634 patent in 1984 until Cyanamid ceased enforcing the '634 patent due to this pending litigation in 1994, less Cyanamid's production and marketing/distribution costs, and compared them with the sales of co-industry leader Stuartnatal's unpatented product, less production and marketing/distribution costs, over the same period of time. Based on this analysis, which the district court determined to be credible, persuasive, and conservative, the district court found Cyanamid was unjustly enriched by $23,243,228. Accordingly, the district court did not clearly err in its factual findings underlying its award of damages for unjust enrichment.
