Patent expiration, LED packaging company or welcome opportunity
As we all know, the technical patents of the global LED industry have been firmly grasped in the hands of Cree, Philips, Osram, Nichia and Toyota Synthetics. In order to maintain their competitive advantage and maintain market share, these five major manufacturers have applied for a number of patents covering the entire industry chain, including raw materials, equipment, packaging and applications.
However, the feng shui turns, this patent barrier is not unbreakable, but there are signs of loosening. According to the provisions of the Patent Law, the period of protection of invention patents is 20 years, and the period of protection of utility model patents and design patents is 10 years, that is, LED-related patents that have been proposed since 1990, which have gradually expired since 2010, and this A significant portion of this also involves important white LEDs. In other words, in the next two to three years, a group of core patents in the 1990s will expire. In addition, related patents involving phosphors will gradually become ineffective during 2012-2014.
Therefore, the development of LED packaging enterprises will usher in new opportunities, and it is expected to emerge in the non-phosphor white LED lighting technology.
The barriers are warming up, and the "cottage version" patent is buried.
In recent years, domestic LED companies have applied for LED patents in an endless stream, but if you study them carefully, you will find that most of the patents are not original. They are either picking up people's teeth, making some repairs based on the original patents of international LED giants, or opportunistic. In the utility model or design, the patent "cottage" is quite high, and the gold content is naturally greatly reduced. In the face of global lawsuits triggered by international giants, more than 70% of domestic patents will expire.
At present, LED companies exporting to overseas markets have frequently suffered from patents. At the same time, with the rapid development of the mainland LED lighting industry, international lighting giants have taken advantage of the core technology to seize the Chinese market. Although China's LED industry has an advantage in terms of output and price, it is difficult to keep pace with international first-line brands in terms of technology. At that time, the foreign brands will be under pressure and the patents will be self-respecting. The LED industry may repeat the mistakes of the photovoltaic industry. Some experts even predict that in the next two to three years, it is very likely that foreign giants will collectively accuse the local small and medium-sized lighting companies of patent infringement.
However, it is gratifying that some companies have begun to plan ahead. For example, Zhen Mingli and Zhong Ming signed a patent cooperation agreement with Philips in February and April 2012 respectively. In November, Jingdian and Toshiba of Japan authorized the AlGaInPLED technology patent. In addition, the Taiwan factory also announced in December that it will be authorized to interact with Toyota Synthetic.
It is foreseeable that as market competition intensifies, patent disputes will become the norm. In order to prevent problems before they occur, Xiao Bian suggested that enterprises should try to purchase some technical patents in the absence of a trump card patent, or jointly funded by a number of enterprises to obtain licenses. At the same time, through the establishment of patent alliances, strengthen patent strategy research. Boldly adopt the "patent pool" method, integrate many patents of patent holders, cross-authorize and license each other, and finally respond to the "encirclement and suppression" of international LED giants in a group manner.
Market segment or current patent "new pet"
It is true that the vast majority of LED core technology is in the hands of a few international manufacturers, but LED crepe, do not have to look down on it. Throughout the history of LED development, LED application field development can be described as new, from the initial mobile phone backlight, to the current lighting, from behind the scenes to the front, and in the future will be in the direction of artificial intelligence. Therefore, for the discovery of LED patents, whether it is innovative invention, utility model, or design, there is a great space:
1) Silicon substrate patents are expected to achieve even better results: In 2012, the Chinese manufacturer Jingneng Optoelectronics launched a luminous efficiency of more than 120lm / W silicon-based high-power LED chip products, let us fully exaggerated. The industry believes that in the field of sapphire substrate LEDs, Chinese LED companies have almost no core technology patents and have been in a passive state. However, in terms of çŸ½ substrate LED chips, Chinese LED companies can stand on the same starting line as foreign manufacturers, and are expected to break through the perimeter and create patents on silicon substrates to compete for market voice.
2) Artificial intelligence LED or new favorite: Smartphones and tablets have become household names, and the combination of artificial intelligence control technology and LED applications has become a trend. Recently, Philips invented Huelights that can be controlled through Android and iOS technology programs. The American indoor lighting company ByteLight has developed a positioning service based on LED lights, which allows the program to calculate the current position in one second, with an accuracy of up to one meter. The LED luminaire emits a flashing signal that is then received and detected by the user's smartphone camera, and the user does not need to align the camera to a particular direction, and can also receive a direct source signal that is fed back. All of the above indications show that since smart mobile devices are widely loved by consumers, the combination of LED lighting and mobile smart device technology is bound to gain popularity in the near future. You can consider looking for a cooperative connection point between mobile devices and LED technology, conducting technical research and patenting to trigger a new round of LED technology storm.
All in all, patents are a long-lasting battle. It is necessary to focus on technology and build up a thin film. In 2013, even if we can't do the world's top three, we must use the positive energy to overthrow the patented mountains, or independent research and development, independent innovation, or cross-authorization, and break through the group. In any way, in the spring of the recovery of all things, plant a belief. I believe that the season of spring blossoms will not be far from us.
