Ddun heavy work: the maintenance of intellectual property will never concession
Recently, a suspected infringement shield Xuzhou Heavy Machinery Manufacturing Co. Ltd. patent full casing rotary drilling rig is used in a Nanjing construction site, heavy shield to the Nanjing City Intermediate People's court filed a patent infringement lawsuit, the Nanjing intermediate people's court has accepted the law of tort and equipment for the preservation of evidence.
Chen Jianhai, general manager of Dun heavy industry, said that he will continue to pay attention to and follow up the lawsuit, and resolutely safeguard the lawful rights and interests of the enterprises in accordance with the law. He hopes the infringer will immediately stop the infringement and compensate for the economic losses brought by the infringement to shield heavy industries.
It is understood that the series of patent rights including heavy shield "full rotary rig linkage sequence Benoto" (Patent No. CN201220627594.5), "full casing rotary drilling rig pressure gear device" (Patent No. CN201220627330.X) two utility model patents.
According to understand, in January 2016, the shield of heavy industries to the Xuzhou City Intermediate People's court filed a patent lawsuit, Xuzhou City Intermediate People's court for the preservation of evidence of the alleged infringement unit in the workshop full casing rotary drilling rig, and on January 21, 2016 public hearing hearing testimony. Heavy shield in Xuzhou patent rights litigation involving patents including "sleeve clamping device of full casing rotary drilling rig" (Patent No. ZL201110215928.8), "full rotary rig automatic casing swing control device (Patent No. ZL201210482701.4), the operating system with full casing rotary drilling rig" (Patent No. ZL201210482599.8) a total of three.
According to the "People's Republic of China patent law" article eleventh: invention and utility model patent was granted, unless otherwise prescribed in this law, no unit or individual without the authorization of the patentee, not implement the patent, which may manufacture, use, offer to sell, sell or import the patented products for the purpose of production and operation, or use the patented process and use, offer to sell, sell or import the product directly obtained the patent.
Dun heavy industry regards independent research and development as the core competitiveness of the company, develops and produces full casing rotary drilling rig with completely independent intellectual property rights, breaks through the technology blockade of developed countries, and creates multiple domestic and international ones. Up to now, the company has applied for more than 70 national patents, and has obtained 46 national patent licenses, of which 5 are national invention patents, 39 are utility models, and 2 are design patents.
Always, always keep up with the global shield heavy equipment manufacturing and construction technology, and through the domestic famous universities and research institutes are long-term, in-depth technical cooperation, every year to invest a lot of manpower, material and financial resources for research and development, maintain industry leading technology.
Although "shield heavy industry" is the pioneer of this industry, we never exclude fair competition. We welcome more enterprises to join this industry. But some enterprises are unwilling to invest in R & D, directly embezzle our technological achievements and push them to the market at low price, which not only directly damages our interests, but also confuses the industry order, blows up innovation enthusiasm and is not conducive to healthy and orderly development of the industry. We welcome the proper competition, and are willing to work with the industry colleagues, with innovation as the driving force, joint full casing full rotary drilling machine industry to be bigger and stronger!
