The lawsuit alleges that Forepi is infringing Toyoda Gosei's patents (see below) with regard to GaN-based LEDs, and seeks an injunction against various Forepi LED products.
Prior to the lawsuit in Taiwan, Toyoda Gosei also filed a patent infringement lawsuit in the US District Court, Northern District of California on February 21, 2012. This lawsuit also alleges infringement by Forepi of Toyoda Gosei’s LED chip patents (see below), and seeks damages and an injunction against various Forepi LED products, amongst other remedies.
In its press release, Toyoda Gosei said that it has “respected others’ and our own intellectual property rights in Japan and other countries, and have made our best efforts to further develop the market. Particularly in Taiwan, we have not only manufactured and sold our products and procured parts, but we have also established cooperative relationships with our partner firms with regards to manufacturing.”
