According to the scene of the Frankfurt Lighting Fair, KLITE (Ningbo, Zhejiang) was reported for allegedly infringing on the filament lamp patent, resulting in the stall being surrounded and requesting a rectification booth. The allegedly infringing LED filament lamp bulb was suspected of being confiscated.

It is reported that the company that initiated the lawsuit is Taiwan's "liquid-solid-state lighting" company. According to public information, Liquid-Solid Solid-State Lighting Co., Ltd. was established in 2006 and is dedicated to the research and development of best vintage LED bulbs and lighting systems. Since its inception, the products have won many awards for invention exhibitions. Among them, LED filament bulbs have obtained invention patents in many countries including Taiwan, the United States, Japan, China, and Europe. TSMC bought the company in 2009.
Ningbo Kaiyao is a leading supplier of LED lighting application products and professional solutions. Ningbo Kaiyao is among the leading companies in the outdoor LED String lights market in China. Kai Yao Lighting, jointly established by Ningbo Kaiyao, Haining Kaidi, and Zhejiang Far East, ranked first in LED filament lamp exports in the first half of 2017. Its major exports are the United States, Poland, and France. The three countries accounted for the total proportion. Up to 72%.

In fact, as early as January 7, 2015, Ningbo Kaiyao Lighting obtained the patent authorization of Zhejiang Ruidisheng LED LED filament lamp. It is reported that the LED filament lamp produced by Ruidison Company was led by a team of retired researcher Ge Shichao of Zhejiang University. The LED filament lamp has been patented worldwide.

Ningbo Kaiyao is the lighting company with the largest export volume of Giant Flexible LED filament bulbs in China. It is not surprising that it has become the focus of attention of companies in the same industry in China and even in the world. If this infringement is true, it is bound to cast a shadow on the export sales of Ningbo Kaiyao LED filament lamps.

For this patent dispute, Ningbo Kaiyao quickly clarified the facts to prevent negative impact on the company. A formal legal statement was issued on the matter. The statement stated that the filament lamp accused of infringement was covered by a patent numbered DE 202015100715, which was authorized by patent owner SIM LIGHTING DESIGN COMPANY LIMITED to Kai Yao.
