Case report: Toshiba loses semiconductor patent

After sending warning letters to Arima Optoelectronics Corporation (AOC), Toshiba sued the company at the IP Court for patent infringement based on the alleged continuous sale and use of similar LED models. The ‘588 patent was twice amended after being granted, in 2013 and 2014. While the 2013 amendment was approved by the Taiwan Intellectual Property Office (TIPO), the 2014 amendment was pending before the TIPO when the IP Court ruled on the case on September 22, 2015.
