After the white LED patent era China LED factory can change the game board?

2017-08-14 10:24:49

LED industry in the past by the Nichia Chemical, OSRAM Opto Semiconductors, Career (CREE), Toyota synthesis, Lumileds and other five manufacturers to create a huge patent network, any want to sell overseas market LED manufacturers, more or less need to pay Pay "protection fee" to smooth passage. However, with the expiration of the patent, China Taiwan and South Korea manufacturers rise for the patent power, as well as mainland China manufacturers strive to upstream, so oligopoly patterns have quietly changed.

Five patent network gradually decline


In the past, LED patent litigation cases are mostly patented manufacturers accused of Taiwan, South Korea and mainland China manufacturers, which in turn the most tough chemical industry, the highest frequency of patent warfare. Nippon Semiconductor and Seoul Semiconductor's patent war in 2009 after the end of the settlement, Seoul Semiconductor has become a member of the patent licensing network, the past five-year patent licensing situation and thus transformed into a hexagram type.

However, with the five patent manufacturers of the industry more and more difficult, other patent manufacturers began to change the collection of patent licensing or patent release of the way to survive. In addition, Nichia Chemical known as the door god level white patent (YAG patent 925) will expire on July 29, 2017, together with China's Taiwan billion photoelectronics held by the Nichia Chemical patent pending patent litigation, But also in the United States and other countries to obtain a patent invalid verdict, has significantly weakened the strength of Nichia chemical patent. With the LED manufacturers to build the patent wall began to collapse, in the past these manufacturers rely on patent barriers in the global LED market booming rain fear no longer.

Chinese mainland manufacturers trying to obtain overseas market tickets

In addition to the key patent will expire, may affect the past, the rigorous patent network, the Chinese mainland manufacturers of dynamic, but also for the white patent era to bring a lot of variables.

From the LEDinside LED market ranking observed, the Chinese mainland LED manufacturers large-scale expansion, has squeezed into the world's top ten. In addition, the Chinese mainland manufacturers in recent years through acquisitions to obtain a lot of overseas companies, such as China Electronic Information Group made Bridgelux stake in the acquisition of three Luminus Luminus, and Toyota synthesis license Ruifeng and poly fly photoelectric, have shown that mainland Chinese manufacturers trying to obtain Tickets for entry into overseas markets. Coupled with more and more international brands began to OEM orders released to the Chinese mainland LED manufacturers, the export of its products overseas market share gradually increased. China's strong rise in mainland manufacturers, the international manufacturers and other regions of the manufacturers caused a great threat, the future of patent litigation is expected to emerge in an endless stream.

And Taiwan-based manufacturers billion light in June 2017 on Puri Optoelectronics (Bridgelux, Inc.) filed suit, it is understood that infringing products, including widely used in lighting 2835 products. Puri Optoelectronics claims that the world has more than 750 LED chip and packaging technology patents, and patented patent dispute with Career, the parent company for China Electronic Information Group. This is the Chinese mainland manufacturers through the overseas acquisition of LED companies to enter a specific example of overseas markets, follow-up development is worth observing. The billion light take the initiative to punch, but also highlights the changes in the LED industry map, manufacturers have adjusted the strategy, and actively maintain their own advantages.


Japan and South Korea and Taiwan manufacturers will move to downstream manufacturers litigation

In recent years, China Taiwan and South Korean manufacturers in the patent litigation strategy, but also with the sudden change in industrial situation and change, China Taiwan and South Korea manufacturers as a result of increasing competition, the cost and loss to the Chinese mainland manufacturers, Patent litigation, through litigation to prevent.

According to LEDinside observation, to LED lighting, for example, if the lighting foundry want to export products to Europe, the United States, Japan and other patent-protected market, basically still need to use no patent concerns LED, retail access and lighting brands will accept , So most of the foundry had to choose the five major manufacturers of production, the higher the price of the LED. But consider the cost, some products will choose Seoul Semiconductor, Samsung LED and LGIT and other Korean manufacturers of LED components. And China Taiwan's billion photoelectronics and Nichia chemical patent litigation made a favorable decision, and then with the wafer of the chip, the product certainly customers can be marketing the world.

In the past, the LED industry was dominated by competition among competitors, but recently there have been a large number of cases that are directed against application vendors. In the past, the industry was reluctant to sue the application vendor because the application vendor might be a competitor customer or a customer. Application manufacturers have always been holding the LED "A brand of LED with some, B brand also use some, C brand also use some" mentality, that since it has been a customer, there will be no litigation issues The But in March 2016 Nichia Chemical first to break this practice, the North American first TV brand Vizio litigation, and then also on the Feit, Lowe's, TCL and other manufacturers filed the same patent litigation, which, Lowe's North America's second largest DIY Path, second only to Home Depot. It is understood that the respondent object to a certain extent to use the day of the product, these cases are still in progress.

With this precedent, wafer-based optoelectronics, billion light, Seoul Semiconductor, etc. also adopted a similar strategy. First, Jinggui and Seoul have made patent litigation for LED filament products, the current part of the litigation has reached a settlement, but the downstream LED lighting industry has a vigilance. April 2017 crystal power accused the US channel manufacturers Lowe's, and billion light also on Nichia Chemical, Citizen Electronics and its customers large light motor litigation, it is understood that the large light motor is one of the top five lighting factory in Japan. In view of these increasingly directed by the client's patent litigation more and more, but also to re-thinking of the LED industry, whether in 2017 to 2018 after the expiration of the patent license in Japan, the patent competition will come to an end

LEDinside believes that despite the maturity of Nichia's patent, patent network loosening has made the manufacturers to change their patent layout and strategy, however, this does not mean that the patent door on this open, but only the beginning of patent warfare. Because Nichia Chemical past the absolute dominance of the patent monopoly has ceased to exist, coupled with the LED manufacturers have their own patents, the gap between each other has been narrowed, is expected to continue the patent warfare, LED application manufacturers still have to be careful to respond.
