Chamberlain Group prevails in patent infringement case

Federal jury finds that Techtronic Industries Co. Ltd (TTI) willfully infringed on two CGI patents

Oak Brook, Ill., Aug. 31, 2017 (GLOBE NEWSWIRE) -- A unanimous Federal jury in District Court in Chicago found in favor of Chamberlain Group in the assertion of patents against Hong Kong-based Techtronic Industries Co. Ltd (TTI), the parent company to brands such as Ryobi, Milwaukee, Hoover and Oreck, and several related entities. The jury found TTI to have willfully infringed on two U.S. Patents (U.S. Patent No. 7,635,966 and 7,224,275) through the manufacture and sale of its garage door opener under the Ryobi brand sold exclusively through The Home Depot.
