Nalco litigates patent and antitrust claims against competitor

Clients Ecolab Inc.

Jones Day served as lead counsel to Ecolab Inc. subsidiary, Nalco Company, LLC, which alleged that a competitor committed fraud on the Patent Office in obtaining a patent on a method for removing contaminants from high-calcium crude oil and that the competitor used that patent to force Nalco from the market. Nalco asserted antitrust claims based on Walker-Process and sham litigation theories, as well as claims for tortious interference and malicious prosecution.
