Dongbei stressed that the US company Carey Cree filed a commercial interference lawsuit against the company's (Dongbei) and the company's (Dongbei) customer products. In fact, it deliberately used the old products to apply the new regulations to confuse the audience. The other party used the new standard implemented in September 2014 to test Dongbei's products that met the requirements under the old standard. At the same time, it deliberately discredited the old products and failed to comply with the energy-saving regulations. The product advertisements were not true and violated the fair competition trade.
It is reported that Cree's alleged products are in compliance with the old standards, and Dongbei has stopped production at the end of 2014. At present, Dongbei is mass-produced products that meet the new energy star standards by the new standard. I believe this accusation will come out in 2015. The cargo plan should have no impact. 
For the patent lawsuit filed by Cree Cree, Taiwan LED packaging company Dongbei Optoelectronics pointed out that the company is convinced that its own products have no infringement, and will defend against Cree with its customers and shareholders. It is expected to negotiate with lawyers. It is proposed to propose counter-action against Cree’s complaint.
