6 OSRAM LED industry on patent issues

Patent issues have been hot, LED industry patent war has never stopped. Patent strategy, careful layout is, "unchecked laissez faire" have it. The industry believes that the patent war inevitable, after unabated, there are also waiting for the industry giant patent expires.

There is also a patent for yongcu people criticized the industry giant OSRAM in the end how to see. Come together to listen to the patent licensing officer Dieter OSRAM Boss how to say.

It is extremely difficult to avoid OSRAM patent portfolio

1 what are OSRAM's core LED patents? Are these patents important for the production of white LED devices?

OSRAM's core LED patent relates to phosphor converting photochromic LED technology. The technology in the LED industry has been widely used in the production of white LED, the principle for the blue LED chip (usually a gallium nitride semiconductor) issued by blue light conversion fluorescent powder corresponding to one or more color, and not converted into white light and blue light mixing.

The OSRAM core LED patent portfolio includes all kinds of patent rights, involving many different fields, one part of the patent relates to the use of YAG phosphor particles size distribution of LED products, some other patents involving the use of silicate phosphor LED products; in addition to many other patents describing the structure characteristics of color conversion technology program elements and LED package many, but not limited to fluorescent powder material.

In short, OSRAM's core LED patent portfolio covers many different areas and levels. As a result, it is extremely difficult to avoid all of these patents, especially in the production of white LED devices in the global market.

At present, more than more than and 20 active in the global market, the main LED manufacturers have access to OSRAM's core LED patent license, the beginning of this year, East Bay optoelectronics has become a new member of OSRAM's core LED patent licensing program.

2 what are the important patents involved in the production of white LED devices?

All aspects of the entire value chain of the semiconductor industry may include intellectual property issues, including patent issues, such as semiconductor epitaxy, chip design, and other front-end processes involving thousands of patents. LED materials, LED packaging, COB board chip design, as well as the back-end process also involves thousands of patents.

Among them, the phosphor converted light emitting LED technology has long been one of the most prominent hot issues in the LED industry. In particular, the use of the following phosphor materials has led to a number of patent disputes: Yttrium Aluminum Garnet Phosphors (such as YAG), Silicate Phosphors (such as B.O.S.E.) and emerging nitride phosphors (such as CASN). In addition, there are many hot spots in the semiconductor chip and packaging technology.

3 it is reported that some of the LED manufacturers in China have obtained the patent license of B.O.S.E. phosphor from TOYOTA synthesis. The news that the LED manufacturer of white LED lamp so no longer patent problems, are free to enter the international market. Is that right?

This authorization is called the B.O.S.E. licensing patent, buy B.O.S.E. fluorescent powder to the qualified suppliers, can solve a patent problem, also is about B.O.S.E. the patent issues.

However, other patent issues such as the production of white LED devices have not been resolved. For example: as the authorized person of the B.O.S.E. licensing project, as soon as possible to join the OSRAM core LED licensing project.

Total effective patents will continue unabated

4 as everyone knows, the industry known as the "big 5" (Nichia, OSRAM, PHILPS, CREE, TOYOTA and Lumileds have been synthesized) some LED patent cross licensing each other using their own. Can other manufacturers solve all patent problems by getting a patent license from one of the 5 major manufacturers?

Indeed, these 5 manufacturers LED industry has reached a number of bilateral agreement on intellectual property rights. However, the licensing of these bilateral agreements is limited to one party in the use of their own products in the other side of the patent, which does not extend to the authorization to the third party.

5 OSRAM's core LED patent portfolio to the period of validity?

Most of the patents will expire in mid, and some will expire in late 2016 or early 2018.

6 to 2018, the existing patent structure in the underlying LED patent expires in 2017 will completely change it?

Indeed, some of the basic LED patents will expire in 2017. However, these will expire at the end of 2017 the basic patent is only a small part of LED related patents. In all aspects of the entire value chain of the semiconductor industry, including the epitaxial wafer and chip technology to packaging and module technology, there are still thousands of other patents. The majority of these patents remain in effect after 2017.

In addition, as far as OSRAM knows, there is no significant change in the industry's LED research and development and patent investment. As a result, OSRAM believes that the total number of valid patents related to LED will increase in the coming years. LED technology has been and will continue to flourish in all directions and levels. The layout of the corresponding intellectual property has also continued to follow up. With a number of different technologies to achieve market success, OSRAM believes that the new hot spots will also come out of intellectual property
