Patent litigators from the law firm Warner Norcross & Judd LLP have successfully defended a patent infringement case brought by Attica Automation covering automated inspection equipment.
Earlier this month, a jury in the U.S. District Court in the Eastern District of Michigan agreed that Clawson-based Linear Group Services and ND Industries had not infringed a patent owned by Attica Automation. Attica brought its suit in 2013 against Linear and ND Industries, alleging that Linear had copied patented technology in developing its new automatic sorting equipment. Attica also accused ND Industries of infringement through its use of Linear’s machines.
Linear introduced a new automated inspection machine in 2011, which quickly gained acceptance by the fastener industry. The Linear machine adopted a new approach, removing the “good parts” from the line and allowing “bad parts” to continue on into a reject bin. Previous systems, including the method covered by Attica’s patent, had removed the “bad parts” from the line. read more
