Patent disputes in the LED industry are nothing new. From chips to packaging to materials, the “patent war†has been accompanied by the development of the entire industry.
Cree's global patent battle encounters "small setbacks"
Taiwan's LED packaging factory Hongqi Technology successfully invalidated the Chinese patent (Patent No. X) of Cree's Huizhou Cree Semiconductor Lighting under the name "Devices and Methods for Installing Electronic Components".
Hongqi Technology issued a statement stating that the invalidation procedure was entrusted to Beijing Tongli Yucheng Intellectual Property Agency Co., Ltd. on December 22, 2014. The Patent Reexamination Board of the State Intellectual Property Office of China officially announced the patent on July 26, 2015. The rights are all invalid.
Cree is accused by Fett Electric of infringing LED patents. In 2015, Feit Electric announced a patent infringement lawsuit against Cree in the Central District of North Carolina to prevent Cree from continuing to sell 4FLOW LED bulbs and seeking damages. Felt Electric claims that Cree's 4FLOW LED bulbs infringe its US Patent Nos. 8408748 and 9016901.
Dongbei made a counter-action against CREE's complaint in 2015. For the patent litigation filed by Cree, Dongbei Optoelectronics also responded that the company is convinced that its products have no infringement, and that it will defend its rights with its customers and shareholders. In the face of Cree, it is expected to propose a counter-action against Cree’s complaint after consulting with a lawyer.
The patent battle between Cree and Xuming both to reconcile Cree and Xuming Optoelectronics for more than a year, the two sides agreed to end more than a year of patent infringement lawsuits. Xuming Optoelectronics agreed to implement a ban that will take effect on October 1, 2012, prohibiting the import and sale of products that SemiLEDs have been accused by the defendant in the United States, and a one-time reimbursement of Cree for the damage caused in the past.
GE accused lighting science infringement of being rejected by GE Lighting. Six LED manufacturers, including LSG, infringed on two of their LED patents, US Patent No. 6,787,999, entitled "LED Modular Light Source Product Patent", and US Patent No. 6,979,864. Named "High Power LED Power Pack Patent for Spotlight Modules".
In August 2015, the Lighting Science Group announced that the US District Court for the Northern District of the United States granted LSG's summary judgment motion and declared that certain GE Lighting patents were invalid, and rejected GE Lighting's patent infringement claim against LSG.
Nichia Chemicals suspends WOFI infringement on August 31, 2015. Nichia went to the German court in Düsseldorf, Germany, and allegedly infringed on Japanese patents against WOFI, a German subsidiary of Taiwan Everlight.
The Japanese accused WOFI, based on the latest approved YAG patents (ie EP080 and EP053), requested the court to issue a permanent injunction, ordered WOFI to file the relevant books and award damages.
White LED patent dispute victory over Nichia billion light <br> <br> billion light in April 2012, Japan Asia-based white LED US Patent No. US 5998925 and US 7531960, in the United States District Court for the Eastern District of Michigan filed a patent is invalid and Non-infringement claim.
On April 22, 2015, the jury of the District Court of the Eastern District of Michigan in the United States decided that the rights claimed by Japan Yahua were invalidated on the grounds that the patent was not progressive and the patent was not enforceable.
As early as March 2012, Yiguang also filed a patent invalidation lawsuit against the German Federal Patent Court in the German Federal Patent Court, German Patent No. DE 69702929 (EP 0936682). The German Federal Patent Court issued an invalid judgment on the patent in September 2014, which contained all the rights of the patent as invalid, and the Japanese Asianization had to bear the referee fee.
Seoul Semiconductor accuses Craig of electronic infringement LED patents. In 2014, Seoul Semiconductor (SSC) filed a Craig patent infringement lawsuit in the Southern District Court of Florida. The lawsuit includes a core technology to produce LED chip manufacturing technology foundation, LED packaging technology, lens technology, and backlight unit (BLU) technology.
In July 2015, the lawsuit had the latest results. The court confirmed the validity of its five patents and patent infringements.
Dow Corning v. Commet's infringement was invalidated On May 18, 2015, the Patent Reexamination Board of the State Intellectual Property Office officially issued a document stating that Dow Corning's patent number is ZL 03824673.2, the invention patent - "curable organopolysiloxane composition and All patents for semiconductor devices fabricated using this composition are ineffective.
In the LED high-end high-refractive-package silicone industry, the Japanese company Dow Corning v. the domestic company Commet's infringement case has been entangled for nearly one year. This innovative R & D results related to ownership of the patent battle finally settled <br> <br> OSRAM sued ASUS violated its white LED patent in May 2015, Osram announced in litigation against manufacturers of consumer electronics in Taiwan's Asustek patent infringement In the middle, won the first-instance judgment.
Osram claims that some of the white LEDs used in ASUS's first-generation Nexus 7 tablet infringe its German patent DE 196 55 185. The Düsseldorf District Court granted OSRAM an injunction and ruled that ASUS must compensate for the losses caused by patent infringement to OSRAM. ASUS appealed against this ruling, while OSRAM initiated enforcement.
Japan won the Nobel prize to detonate blue LED patent battle <br> <br> formerly engaged in Tokushima Prefecture Nichia Shuji Nakamura, two research and development, has developed a blue LED in the early 1990s. In 2001, Nakamura went to court with the company and demanded to pay 20 billion yen. After that, the court repeatedly persuaded the two sides to reach a "reconciliation" with 840 million yen (about 40.42 million yuan).
Audubon group stringent patent protection LED <br> <br> Tridonic together with Toyota Gosei Co., Ltd., Germany LeuchtstoffwerkBreitungen GmbH and LitecGbR composed BOSE Union, owned by blue LED and the yellow silicate phosphor to generate white light technology Basic patent.
In March 2015, under the authorization of the BOSE Alliance, Tridonic filed a patent infringement lawsuit against AOC International (Europe) BV and AOC International (Europe) GmbH, which infringed the EP1352431 B1 patent held by the BOSE Alliance.
summary:
Shopping malls such as the battlefield. The market is changing rapidly. If you want to survive in the market and have breakthrough development, you must have a "weapon" that can be surprisingly successful. Price competition is no longer the best policy, and the price/performance ratio has long been hanged by companies. Patents, which have been under-recognized in the past, are increasingly being mentioned.
