The hottest patent dispute between Vestas and GE

  • Detail

The patent dispute between Vestas and Ge

friends in the wind power industry know that there are several well-known wind power machine manufacturers in the world, including Mr. Zhao Honghan, the Secretary General of the China unsaturated resin Association and an industry expert, who spoke highly of Vestas, the giant of Denmark, General Electric (GE) and no in Germany after visiting the R & D center Enercon, Siemens COMESA (sgre), which completed the reorganization this year, and our domestic brand Goldwind

for high-tech products such as fans, a breakthrough invention will reduce the overall cost of fans and increase the competitiveness of enterprises. Therefore, patent application is very important for enterprises

today, I want to talk about the patent dispute between GE and Vestas, two of these giants

second prosecution, and use patents to suppress opponents

on July 31, Ge filed a lawsuit against Vestas in the California court, claiming that the latter was suspected of infringing its 705 patent. Ge said that Vestas' v.0 MW, v.0mw and v.3mw wind turbines installed in the United States used this patented zero voltage ride through technology called "methods and equipment for operating electric machinery". Ge said it had the right to claim compensation from the defendant and would seek legal means to organize Vestas to continue to use the technology

what is zero voltage ride through technology

in the process of electric operation, voltage drop in a short time often occurs due to excessive load, lightning or short circuit. In order to avoid the damage caused by voltage drop to the system, the wind turbine disconnects and attempts to reconnect. The low voltage ride through technology can keep the fan in operation without disconnection under this condition. GE's zero voltage ride through technology enables the unit to maintain and operate even when the voltage drops close to zero. Low voltage ride through technology plays a key role in the overall operation stability of the fan, so it is a key field in the research and development of various machine manufacturers

ge believes that California is a good place to sue Vestas, because both San Gorgonio wind farm and Brookfield wind farm in California use Vestas fans. Ge also said that Vestas' branch in the United States has cooperative behavior with California

in fact, this is not the first time GE has initiated a lawsuit against the 705 patent

as early as 2008, Ge sued Mitsubishi Heavy Industries (MHI) of Japan for allegedly using this patent on its 2.4MW flagship wind turbine in the United States. Mitsubishi Heavy Industries then initiated an anti lawsuit against Ge in a Florida court, accusing ge of trying to monopolize the U.S. market

the lawsuit lasted for five years, and the jury of Ge asked the defendant to compensate the plaintiff for the loss of $170million. Finally, the two sides reached a settlement in 2013, ending the dispute with a cross authorization agreement

however, Mitsubishi Heavy Industries' customers lost confidence due to this lawsuit, and their fan business was seriously damaged. In the end, Mitsubishi's 2.4MW platform plant, which invested $100million in the United States, shut down without even producing a fan

after four years, Ge once again took advantage of the 705 patent to play a game with another machine giant. Is it to protect its own rights or to try to use this means to hurt Vestas' market in the United States? There are different opinions about the purpose behind it

ge tells Vestas, why do we act now

in 2016, Vestas accounted for 43% of the total installed capacity of wind power in the United States with an installed capacity of 8.3gw, becoming the overlord of the manufacturing industry of wind power machines in the United States for the first time, slightly better than the local giant Ge by 1%

ge said that as early as 2011, Vestas knew that 705 technology belongs to GE's patent, because an engineer of Vestas once attended the jury of Ge and Mitsubishi Heavy Industries and gave testimony. Some analysts said that if Ge could file a patent lawsuit to the court within this period of time, it would likely hinder the momentum of Vestas and continue to maintain its dominant position at home

why did Ge take so long to file a lawsuit

it is commented that GE has been busy acquiring French energy giant Alstom and blade giant LM in recent years and has no energy to file a lawsuit with Vestas. Dan Shreve, partner of Danish wind energy consulting firm make in Boston, commented in his blog post that GE had become cautious due to the last lawsuit with Mitsubishi. Unless the infringement risk was large enough and the evidence was sufficient, it would not easily open Pandora's box. From this point of view, Vestas took the spotlight from GE in 2016, making Ge realize that it must take some action to deal with this foreign behemoth

the giant's patent war may lose both sides

one is the industry leader focusing on wind power, and the other is standing on the shoulders of giants. Ge renewable energy group has greatly improved its competitiveness after acquiring Alstom and LM. Nengdoujun collated and compared the basic data of the two giants. (the data of Ge in the table is the data of Ge renewable energy department. More than 90% of the business of this department is onshore wind power, so although it cannot completely accurately describe GE's wind power business, it is representative)

it can be seen that Vestas is slightly better than Ge in terms of total installed capacity and new installed capacity in 2016

today's intruder Vestas has far surpassed its rival Mitsubishi in terms of scale and product quality. GE's hope of winning this lawsuit is far less than that of four years ago. In addition, Ge also faces the risk of being counterclaimed by its rivals. Vestas responded that GE's lawsuit was groundless and would challenge its rivals

according to the Research Report of consulting firm totaro associates, by 2016, among the global wind turbine manufacturers, Ge renewable energy group had 1863 patents, some of which were brought by the acquisition of Alstom and LM. Siemens COMESA Wind Technology Co., Ltd. and Vestas ranked second and third respectively, with 125 patents. The methods often used by friction and wear testing machines to measure friction force or friction torque include mechanical method and electrical method 4 and 1117

number of patent applications of global wind turbine manufacturers

although the number of patents of Ge is ahead of Vestas, the strength of its rivals cannot be underestimated. Vestas has applied for patent protection in many regions around the world, and as the first batch of complete machine manufacturers in the wind power industry, there is no other technology to learn from in the early stage, so it can only rely on independent research and development. Predecessors planted trees and descendants enjoyed the cool. After the fan manufacturing process gradually matured, many patents were improved on the basis of existing technology. Nowadays, many patents will have similarities. If Vestas launches a counterclaim, it is likely to make an article about the technology similar to Vestas used by GE

make's shriff believes that if the two giants start a patent dispute war, it will cause losses to both sides and damage the entire U.S. wind power market. However, he believed that the two companies would eventually reach a mediation agreement. For Vestas, the primary task at present is to stabilize the confidence of customers and ensure that customers' interests will not be lost due to this lawsuit. The warning left to Vestas by the failure of Mitsubishi Heavy Industry in that year is that the least expensive resistance is to pay fees to apply for patent authorization from GE. If a lengthy lawsuit like Mitsubishi is fought, it is likely to affect the development of Vestas in the U.S. market
