Not all products are included, and not all patent information about each Ecolab product necessarily is provided here. Ecolab products also may be covered by one or more patents in countries other than the U.S., and additional patent application(s) may be pending in the U.S. or outside the U.S. Ecolab products may be sold individually or as part of a process, system, combination product or service, and the associated patent numbers would apply in both cases.
