June 21, 2017: Taiwan-based Everlight Electronics filed a lawsuit in the US District Court, alleging that Califonia-based Bridgelux, manufacturer of LED lighting sources, has infringed the company’s US Patent 6,335,548 and 7,253,448, which is related to essential and fundamental structures in LEDs.
Everlight has said that Bridgelux has infringed the patents by manufacturing and selling LED products like the 2835 series packaged surface-mount device (SMD) LEDs. The patented technology is used in high-, mid- or low-power LED products.
Besides the US market, Everlight’s patent protection on these structures extends to Europe, Korea, and Japan as well. However, the lawsuit is limited only to such products in the USA and does not cover any jurisdictions outside the USA.
The lawsuit requests the court to stop Bridgelux from selling, manufacturing, importing or exporting any such patented products, and to also demands to be given damages sufficient enough to compensate for Bridgelux’s infringement.
However, Bridgelux says that Everlight’s infringement claims are without merit and intends to defend itself against these claims. “As history demonstrates, Bridgelux respects the intellectual property rights of others and will not be intimidated by the misuse of litigation from those seeking an unfair advantage or seeking to limit the advantage Bridgelux has earned from our technology investments,” says Bridgelux’s CEO Tim Lester.
Bridgelux counter attacks by saying that the lawsuit is the result of its success with its 2835 SMD products in the market, and Everlight’s inability to compete with with it. Bridgelux employs its own patent portfolio to protect its rights.
