The validity of two Marine Exhaust Systems patents was upheld in a recent decision by the U.S. Court of Appeals for the Federal Circuit.
The company won a patent infringement lawsuit against DeAngelo Marine Exhaust in 2010. An appeal that DeAngelo filed resulted in the appeals court victory Aug. 28 on all counts by Florida-based Marine Exhaust Systems, enforcing the original suit's ruling that DeAngelo willfully infringed on the patents.
The patents were for water-jacketed exhaust pipes for marine exhaust systems. Both court decisions found the patents to be valid and enforceable.
"We're obviously happy with the court's decision. We remain committed to protecting the costly research and design investments we make in our products. It's been a long road, but the original truth still stands — our patents are valid," Marine Exhaust Systems vice president Sheila Prieschl said in a statement. "The unfortunate aspect of this whole process has been for customers who unknowingly bought exhaust parts that infringed on our patents and got caught up in the case."
