Patents are being hotly debated, LED industry patent war has never stopped. In terms of patent strategy, have elaborate layout, "unfettered" also. The industry thinks patent war is inevitable, to grow, after also have companies wait for the industry giant patents expire.
For some people criticized others crowned by patent problems, the industry giant osram what to see. Together to listen to osram, head of the patent license Dieter Dr Boss how to say.
To avoid osram patent portfolio is extremely difficult
What are the core LED patent 1. Osram? The patents to the production of white LED devices is important?
The core of osram LED patent involving the phosphor conversion light shine LED technology. The technology in the LED industry has been widely applied to the production of white LED products, the principle for the blue LED chip (usually a gallium nitride semiconductor) issued by the blue part by corresponding phosphor powder into the other one or more of the light color, and not light blue mixture of white light color conversion.
Osram LED the core patent portfolio includes all kinds of patent rights, in many different areas, some of the patents involved the use of a certain particle size distribution of YAG phosphor particles LED products, other patents involving the use of silicates phosphors LED products; In addition to these, there are many other patent description light conversion technology plan elements and LED encapsulation structure characteristics, and is not limited to the kinds of phosphor material.
In brief, osram related core LED patent portfolio covers many different fields and levels. Therefore, in the world's major market scale, especially the production of white LED devices, want to avoid all these patents are at the same time extremely difficult.
Now more than more than 20 main LED manufacturers have been active in the global market osram core LED the authorization of the patent, earlier this year Mr Photoelectric east also become osram LED the core patent license of the new members of the project.
2. The production of white LED devices involved what important patent?
Every level of the whole optoelectronic semiconductor industry value chain are likely to have intellectual property including the patent problem: for example, semiconductor epitaxial wafer, chip design and other front-end process involving thousands of patents. The LED materials, LED chips encapsulation, COB board design, and the back-end process also involves thousands of patents.
Among them, the fluorescent powder into light color light-emitting LED technology has long been a the most outstanding one of the hot issues of the LED industry. Especially the use of the following phosphor material created a lot of patent disputes: yttrium aluminum garnet (YAG) phosphor, silicate phosphor (such as B.O.S.E.) and emerging nitride phosphor (e.g., CASN). In addition, on the semiconductor chip and encapsulation technology and many hot spots.
3. It is reported that some LED manufacturers in China obtained from Toyota to synthesize the relevant licensing B.O.S.E. phosphor. The news that the LED manufacturer of white LED light bead so no longer subject to the patent problem, free to enter the international market. This statement right?
This is called B.O.S.E. permission licensing of the project, to the provisions of the relevant qualification of suppliers to buy B.O.S.E. phosphor, can solve the problem of a patent, also is the problem about B.O.S.E. this patent.
However, as other patent problems of the production of white LED devices has not yet resolved. For example: east bay optoelectronics as B.O.S.E. license authorized person of the project, also recently joined the core of osram LED approved project.
Effective patent quantity will increase
4. It is well known that the industry known as the "five companies" (the chemical, osram, philips Lumileds, sharp and Toyota synthesis) have been authorized the other side of using interactive LED some of their own patent. Other makers can pass one from the five companies to obtain a patent licensing and thus one-time solve all problems?
Indeed, the LED industry of the five companies have some bilateral intellectual property agreement between each other. But the authorization is limited to one of these bilateral agreements in the produced products used in the other side of the relevant patent, these authorization does not extend to license to a third party.
The core of the osram LED the validity of the patent portfolio to what time?
Most patent expires in mid - 2017, there are also some respectively is set to expire at the end of 2016 or early 2016.
6. By 2018, the existing pattern of patent based LED the relevant patent expires in 2017, will change?
Indeed, some basic LED most patent expires in 2017. But these will expire at the end of 2017 the basis of a small part of a patent is only the LED related patents. In all aspects of the whole optoelectronic semiconductor industry value chain, including from the epitaxial wafer and chip technology to package and module technology, there are still thousands of other patents. For the most part these other patent in 2017 years is still in the period of validity.
In addition, as far as osram know, research and patent investment in LED industry, there is no change sharply. As a result, the amount of osram think LED related effective patent will rise over the next several years. LED technology has always been and will continue to flourish in all directions and levels. The corresponding layout of intellectual property rights also continue to follow up accordingly. With many different technical hot spot market success, osram believes the new hot spots will emerge in intellectual property.
