The big five patent networks are fading
In the past, most of the cases of LED patent lawsuits have been filed against Taiwan, South Korea and Chinese manufacturers, with the most aggressive of Japan and the most frequent patent wars. In 2009, the chemical and Seoul semiconductor patent after the war ended in reconciliation, Seoul semiconductor has also become a member of the patent license net, the pentagon licensing situation and thus into six-pointed star type.
However, as the business of the five patents has become more and more difficult, other patent companies have begun to seek to survive in the form of patent licensing or patents. In addition, nichia level is known as the keeper of the white light patent (925) YAG patent expires on July 29, 2017, plus the light electronics for the day of Taiwan chemical held patent filed patent invalidation, also in the United States and other parts of success in the patent is invalid, has been significantly weakened, and the chemical patent intensity. As the patent walls built up in LED factories began to collapse, they were no longer in the wake of patent barriers in the global LED market.
Chinese manufacturers are trying to get tickets to overseas markets
In addition to the expiration of key patents in the big plant, the dynamics of Chinese manufacturers may also affect the future of the patent era.
From LEDinside's LED market rankings, Chinese LED manufacturers have expanded their production to the top 10 in the world. In addition, the mainland Chinese companies in recent years, many overseas companies through mergers and acquisitions, such as the equity of China electronic information group make Bridgelux, three Ann acquisition Luminus, and Toyota synthesis authorization ruifeng and fly photoelectric, all show tickets for the mainland Chinese companies trying to get into the overseas market. In addition, a growing number of international brands have started to release OEM orders to Chinese LED manufacturers, whose export market share has gradually increased. The strong rise of mainland Chinese manufacturers poses a great threat to international manufacturers and manufacturers of other regions, and future patent litigation is expected to emerge.
The company filed a lawsuit in June 2017 against Bridgelux, Inc., which is known to include 2835 products widely used for lighting. The company claims to have patents on more than 750 LED chips and packaging technologies around the world, as well as a licensing deal with Mr Keri, whose parent company is China electronic information group. This is a concrete example of Chinese manufacturers acquiring LED companies from overseas to enter overseas markets. The following development is worth observing. But this hundred million light active boxing, also highlighted in the LED industry landscape changes, the manufacturer has adjusted the strategy, actively maintains its own advantage.
Japan and South Korea have turned the lawsuit against downstream manufacturers
In recent years, Taiwan and South Korea vendors on patent litigation strategy, also with the industry situation of sudden shifts in Taiwan and south Korean manufacturers due to the growing pressure of competition, cost and by Chinese manufacturers, and adopt a proactive patent litigation, creeping through litigation.
Based on LEDinside observation, LED lighting, for example, if the lighting contract to export products to Europe, America and Japan pay attention to the market of patent protection, basically still need to use no patent concerns LED, retail channel and lighting brand will only be accepted, so most of the suppliers had to choose five patents manufacturer production, high price of the LED. But some products will also choose LED components from south Korean manufacturers such as Seoul semiconductor, samsung LED and LGIT. And Taiwan's billion light electronics, which have been awarded a favourable ruling by a patent lawsuit against Japan's chemical industry, are matched by a wafer of photoelectric wafers that can be marketed globally by customers.
In the past, LED industries have been dominated by lawsuits from competitors, but a number of recent cases have been directed against the manufacturers. In the past, companies have been reluctant to bring lawsuits against applications because they may be competitors' customers or their own customers. Application vendors using LED has always held A "A brand of the LED with some, labels also use some of the B, C label also use some" mentality, think now that is the customer, there will be no action. But in March 2016, the chemistry was the first to break the convention, lawsuit against North America's biggest TV brand Vizio, then also for Feit, Lowe 's, TCL and other manufacturers of the same patent litigation, among them, the Lowe's for North America's second largest DIY pathway, second only to Home Depot. It is understood that the subject of the lawsuit is used to a certain extent with the products of the Japanese, and these cases are still ongoing.
With this precedent, a similar strategy has been adopted for crystal yuan, billion light, and Seoul semiconductor. First, both silicon and Seoul have filed patent lawsuits against LED filament products, and some of the lawsuits have been settled, but the downstream LED lighting industry has been alerted. In April 2017, Lowe 's crystal electricity charges the pathway manufacturers, and light for the chemical, citizen electronics and its customers great light motor filed a lawsuit, according to understand the great light motor as one of the top five lighting factory in Japan. There are more and more patent lawsuits directed at the client, and the LED industry is reconsidering whether the patent competition will come to an end after the patent expires in 2017 and 2018.
LEDinside think, though, the chemical patent, patent mesh to loosen makes manufacturers change the patent layout and strategy, however, that doesn't represent patent door is open, but only is the beginning of patent wars. Because, the chemical patents in the past the advantaged position of absolute monopoly has ceased to exist, coupled with the LED manufacturers all have their own patent, the gap between each other has shrunk, expected patent war will continue to spread, LED application vendors still have to be careful.
