Based on tracked cases, Dentons Davis Brown has been involved in disputes concerning environmental technology, specifically mercury emissions control for coal-fired power plants.

Dentons Davis Brown has notably represented defendants in the "Midwest Energy Emissions Corp." patent litigation series. In cases such as Midwest Energy Emissions Corp. et al. v. Berkshire Hathaway Energy Company et al., the firm secured dismissals without prejudice for some defendants due to lack of personal jurisdiction or venue. In Midwest Energy Emissions Corp. v. Wisconsin Power and Light Company, the case was transferred to another district within 16 days of filing, preceding any merits ruling in the initial court. These cases were later centralized as part of an MDL in the Southern District of Iowa. While the plaintiff, Midwest Energy Emissions Corp., has achieved significant verdicts in other related patent enforcement actions (e.g., a $57 million verdict with different lead counsel), Dentons Davis Brown's role in these tracked matters has been in defending energy companies against such infringement claims.
