On April 10, Zhongming and Philips signed a patent technology cooperation agreement for LED light source and various bulbs in Shenzhen.
With the gradual expansion of the sales scale of domestic enterprises in the overseas LED lighting market, the patent risks are also growing. The public technology cooperation between Philips and the patent technology is also based on the consideration of opening up overseas markets.
In fact, similar lighting patent cooperation cases have occurred in the past few months.
In February of this year, Zhen Mingli and Philips also reached a patent cooperation agreement. The partnership allows Zhenming to use all of the LED-related LED light sources and patented bulbs that Philips has opened to the industry.
Gregory Baque, senior director of intellectual property at Philips, said that as China's LED companies grow, we are happy to share lighting technology. Prior to this, more than 175 companies such as Acuity Brands, Osram and ZumtobEL, which have been associated with LED lighting, have signed similar cooperation agreements with Philips. Philips' patent portfolio includes many of the inventions associated with LED light sources and light bulbs. According to the statistics of the High-tech LED Industry Research Institute (GLII), Philips' LED lighting patents have been licensed to six domestic lighting companies.
“The US government is paying more and more attention to intellectual property rights and strengthening patent protection.†Liang Bingwen, a researcher at the Suzhou Institute of Nanotechnology, Chinese Academy of Sciences, said that once a domestic company is bigger, it will be subject to patent litigation by foreign companies.
According to the statistics of the High-tech LED Industry Research Institute (GLII), as of the end of 2011, there were more than 70 enterprises with domestic LED lighting sales exceeding 100 million, and more than 60% of them were mainly overseas markets. This also means that these growing companies will face increasing patent risks.
The reporter learned that in addition to directly reaching patent cooperation with international first-line lighting manufacturers, more and more companies have adopted strategic cooperation with international LED chip manufacturers to avoid patent barriers in overseas markets.
In January of this year, Shenzhen Jin Luming signed a strategic cooperation agreement with Sharp. Jin Luming provided technology and product support for Sharp in the Japanese market. It recommended the application of Sharp chips to customers in the global market, and marked the chip on the product. In fact, China's LED lighting products have been exported to overseas markets and have to use international chips.
At present, the domestic LED industry lacks core technologies, especially the core technologies and patents in the upstream chip field are basically in the hands of international chip manufacturers. On the one hand, the overseas market has strict requirements on the quality of LED lighting products, and on the other hand, several major international LED manufacturers have adopted patent crossovers to carry out patent monopoly.
With the growth of domestic LED lighting companies, there are more and more overseas patent risks. Nichia has publicly stated that if the domestic lighting companies infringing the Japanese patents, once they become bigger in the Japanese market, they will adopt patent litigation.
Regarding the way of patent cooperation and chip purchase, Zhu Dongliang, chairman of Jin Liuming, said: "In order to obtain better cooperation or authorization conditions, Chinese enterprises should first strengthen their own strength."
