LED highbay light patent competition

Poor 10 years. In addition, compared with foreign countries, China's lack of original technology, essentially all of the patent application technologies in the areas of foreign technology roadmap. * China's chip, package and LED highbay light applications with foreign hot application direction deviates. Such as chips, China's patent applications not covered by foreign companies highly valued chip shape technology, surface roughening, the substrate lift-off technique. Packaging field, China's patent applications have their own advantages branch, but in recent years more popular base and the phosphor material gap with foreign countries is huge. Applications, patent applications in China advantage of the technology is relatively mature instructions, landscape lighting, some of the applications involved in the display, and traffic lights, but the technical branch of the international fashion, such as LED highbay light and backlighting applications rarely. * Domestic invention patent applications are mainly concentrated in research institutes and institutions, most of the utility model patent lies in the hands of individuals. Upstream invention patent applications focused on the Chinese Academy of Sciences Institute of Semiconductor Physics and Physics, Changchun-ray machine. Ratio does not exceed 5% of the enterprises occupy invention patents, utility model patents does not exceed 10%. This is very different with foreign-based enterprise application. , Semiconductor lighting patent situation in the development of semiconductor lighting technology very quickly, the industry is far from reach maturity, industrialization chip luminous efficiency of 30lm / W only have very different requirements for general lighting 100lm / W or more indicators. Future technology roadmap in the growing, white light technology roadmap in discover, substrate, epitaxy, chip, packaging technologies are constantly updated. So we still have a lot of breakthrough opportunities. In each technical area applications than or close to the technical branch of the foreign applications, especially in the upstream industry has some peripheral invention patents, which respond to possible patent litigation battle for the future of the bargaining chips. There is still room 1.LED white light for general lighting development, China has the opportunity to work with their foreign counterparts, a higher low. Our composite substrate patents have certain advantages. 3 of epitaxial patent is easy to narrow the scope of protection and to avoid patent litigation more difficult. 4 chips China has great development potential, the white general lighting chip technology with existing technology may be quite different. Promising field of affordable products and application areas. 6.2 years to 3 years will not have large-scale litigation against Chinese enterprises.
Third, China First, the patent system is the use of inappropriate use of the patent system there. The patent system lies in the use of technological achievements to the public in exchange for a monopoly in certain areas and times, then the patented technology is easy to form a monopoly, is it easy to be protected determines the technological achievements are appropriate to apply for a patent. Are appropriate to apply for a patent, when to apply for a patent, how to implement patent protection is an important aspect of the patent system to use, we are somewhat lacking in these places. Second, the scope of patent protection is not appropriate. Foreign patent applications, to claim a very broad, general functional limitations, or physical and chemical properties to write. The rights of our country, often joined many non-essential technical features, the scope of the claims than narrower. Although the theme of protection of a patent application, but the patents of the applicant can be much smaller. Third, the use of the patent system is domestic applicants started late. Since 1985, China has established the patent system to the 1999 patent application blank period. At present, China's semiconductor lighting, the number of patents we have obtained a lot less. Only low-level use of the patent system. Lack of unified deployment of the patentee's patent application, patent applications only in individual individual protection based on the implementation of specific measures is limited to the unilateral licensing and litigation protection. Fourth, the semiconductor lighting patent strategy should be pragmatic in technology to promote the coexistence of a variety of technical route, technical route are likely to form Chinese characteristics has focused on the industrial level to do something, do nothing. In the face of a huge number of patent, to break the monopoly, the establishment of independent innovation, intellectual property, it is necessary to promote the coexistence of a variety of technical route, be focused on Chinese characteristics are likely to form the technical route. Considered from the perspective of technology roadmap, the domestic several echelon study. The first echelon but also around the mainstream of the international technology roadmap to explore the creation of new intellectual property, the main technical route. Second or third tier is necessary to study abroad did not achieve mass production of the new method, out of the the international three techniques route surrounded, such as the development of direct white chips, the development of direct white light white phosphor excited. Considered from the perspective of industry chain, China should focus on the development of packaging and application technology, but the the upstream technology field can not give up. China in every aspect of the upstream accumulation of technology, such as composite substrate in the substrate technology, The epitaxy quantum well and tunnel junction technology, chip technology in the electrode and dicing technology and other fields, China has peripheral has a number of patents, on this basis, should be further play to our strengths, carry out the transverse, longitudinal study, to strive for greater development space. On market development strategy to take advantage of the patented regional characteristics to distinguish between the development of domestic and international routes.
Patents are territorial. Foreign entrants patented technology in China and their actual skills are differences we can make full use of these spaces, take a direct foreign technology not apply in China manufacture, sale and use in China. Recommended that domestic products are mainly take the peripheral route of the basic patent in Europe and America, or to improve the basic patent on the basis of, or looking for Europe and the United States is not peripheral patent applications in China. If access to overseas markets, we can consider the pioneering technology powers did not apply for a patent regions such as the Middle East and African countries. Such as access to the markets of Europe, America and Japan, it is necessary to carefully study these countries patent rights to the scope of protection and patent infringement judgment rule. The United States Department of case law, only in strict accordance with the literal meaning of the claims, any expansion of the explanations are not allowed. European Centre Limited On, claims the scope of protection to the claims set forth the basic kernel, expanding out to make the appropriate explanation. Thus, in the U.S. and European markets, the need to take different measures. The former can be used a variety of methods to circumvent or substitute, such as the overall deterioration equivalent replacement. For the European market, it is recommended not to rush into. If you do not circumvent or alternative, it is recommended that with the introduction of tactics. At present, China's Taiwan manufacturers in order to enter the field of high-end, frequently in contact with a few large companies in Japan, some manufacturers have Japanese company in the upstream patent license. Our country in order to gain a foothold in the upstream industry, you can also take this strategy. Short, to realize the semiconductor lighting, it is necessary to further improve the GaN-based LED luminous efficiency and a significant reduction in production costs. Currently, the domestic institutions engaged in GaN-based LED highbay light research and production, the forces are not very strong, should strengthen exchanges and cooperation, give full play to their respective advantages and concentrate on forward-looking research conducted strive for with independent intellectual property significant achievements and patents. While drawing on the international model of cooperation, patent cross-licensing with these companies to break through the barriers of intellectual property rights, so that you can make the national semiconductor lighting industry for survival and development opportunities, and an invincible position in the fierce international competition .
