3M wins patent cases in Canada and China

July 12, 2011

3M Co. patent lawyers scored wins on two continents over its reflective coatings used on firefighter coats. The Maplewood-based manufacturer said Tuesday that Eurtoex of Canada was ordered by Federal Court in Ottawa to pay damages to 3M and stop selling products that 3M said infringed on its Scotchlite Reflective Material Fire Coat Trim. 3M also said that a court in Shanghai ruled last month that Zhejiang Daoming Reflective Materials Co. infringed on one of 3M's patents related to the same technology.
