The LED Lighting industry has experienced rapid development in recent years. However, after the rapid development and growth, the symptoms of the subsequent weakness of the LED industry are becoming more and more obvious. Patent has become a bottleneck for the further development of LED enterprises. From the appearance of lighting to internal structure, many domestic LED companies lacking core competitiveness will imitate and plagiarize. Seen as the only way out, many companies that focus on patent research suffer.
In the past few years, the semiconductor lighting industry has gradually got rid of the hat with low technology content. The first wave of technological innovation has been basically completed, and patents have become a powerful weapon for enterprises to open up markets and crack down on competitors.
In 2017, the number of patent litigation cases in the LED industry has increased. Among them, domestic and foreign companies such as Japan Yahua, Yiguang and Seoul Semiconductor have been making efforts in the patent battlefield.

Written at the end:
Most of the current technology patents in the LED industry are in the hands of large enterprises. Therefore, the authorization of patents through patent cross-licensing or other means is the primary priority, but this is not secure. For enterprises, the core technology is mastered. It is the safest in your own hands.
Perhaps, the acquisition of patents by means of purchase is also an effective way, such as NVC 500 million acquisition of new generation of LED semiconductor technology international patents. However, it is the key for enterprises to improve their R&D capabilities. Only when they have patents can they have the refusal to plagiarize and let the company go fast and steady.
In addition, from a policy perspective, the government should increase support for small and medium-sized enterprises that lack the strength of patent research, and improve the research strength of small and medium-sized enterprises is an effective measure to truly reduce the phenomenon of patent infringement in the industry. At the same time, promote industry self-discipline and reduce the industry's tolerance for plagiarism.
