St. Michael, MN (June 2018) – U.S. Water announces that on May 25, 2018, the United States District Court for the Western District of Wisconsin overturned a decision by a unanimous Federal Court jury that U.S. Patent Nos. 8,415,137 and 8,609,399 relating to U.S. Water’s pHytOUT® deposit control technology were valid. U.S. Water plans to appeal the ruling and proceed to defend these patents.
