Tianjin Soda Plant is an old factory with 88 years of history. It was once well-known in the world. For every 1 ton of soda ash produced by an alkali plant, approximately 10 cubic meters of waste liquid are discharged, including 300 to 600 kg of alkaline slag. At that time, Tianjin Tanggu had not yet formed a complete urban area. The site around the plant was full of sun salt, and the waste produced by the alkali plant was discharged to the salt pond. In the 88th year, the amount of alkali slag produced and discharged reached 24 million cubic meters, forming three alkali slag mountains and occupying an area of ​​3.9 square kilometers. The treatment of alkali residue leachate and dust pollution has become a major problem in Tianjin.
As early as the 1960s, the Tianjin Soda Plant began to study the comprehensive utilization of alkali slag. Through various proportions of supplementary materials and alkali slag, they were mixed and tested to explore technologies for the treatment and utilization of alkaline slag. The company will publish the soda slag treatment technology in related magazines at home and abroad.
Shortly after the publication of this technology, a company called Tianjin Soda Residue Development Co. found the Tianjin Soda Plant to discuss the cooperation of the technology. Although the cooperation was not discussed later, soda slag real estate company had a certain degree of mastery of this technology. So, in the year of 1995 and September 2, 1996, Caustic Real Estate Company applied to the National Patent Office for a “method for making soda slag†and “patent for soda slag engineering and its manufacturing method and equipmentâ€. He was released to the public in 1997 and 1999 respectively.
In order to allow this technology to exert greater social benefits, the Tianjin Soda Plant, which has no precautions, specially formulated soda residue soil standards and specifications for free use by society in May 1996. It was not until November 29, 1996 that the Tianjin Soda Plant recalled a patent for the "method for the production of soda residue."
In 1996, the government of Tanggu District in Tianjin determined to govern the three soda ash mountains that began in the 1960s. The total soda slag mountain comprehensive treatment project in the Tanggu District will have a total investment of 350 million yuan. Faced with such a big project, the soda residue company has moved. After the start of the No. 6 Wangzi Caustic Slag Treatment Project undertaken by Tianjin Dongteng Company, the alkali residue real estate company made representations to Dongteng, claiming that the soda-soil engineering soil technology used by Dongteng Company infringed on its patent rights, and at the same time believed that The Tianjin Soda Plant that provided the technology also infringed its patent rights and claimed a claim of 1 million yuan.
Originally, it was the first technology developed by the company itself. This was initially felt by the Soda Plant in Tianjin. It was later discovered that people did register patents first. In order to safeguard its own rights and interests, on August 30, 1999, Tianjin Soda Plant requested the ownership of the technology from the State Intellectual Property Office, and at the same time asked to revoke the patent rights of the Tianjin Soda Real Estate Development Company.
However, pending the review of the Patent Office, the soda residue company sued the Tianjin Soda Factory as a third party infringement to Tianjin City in April 2000 on the ground that the Tianjin Soda Plant transferred its patented technology to use by others. Second Intermediate People's Court.
For the lawsuit that should have been called, the Tianjin Soda Plant felt angry and helpless. It only regretted that it had not applied for a patent for its own invention in a timely manner. In order to deal with this case, the Tianjin Soda Plant established a special team with the director as the director, organized hundreds of technical personnel, legal personnel, etc., and allocated special fees to handle the case. The staff of the factory ran back and forth between the court and the national patent office, traveling between Beijing and Tianjin. It took more than five years to directly invest hundreds of thousands of yuan. Until January 7, 2004, the National Patent Reexamination Board made a review decision before it was considered as black and white: the review resolution applied to the already registered Alkali Land Company's "Alkaline Slag Engineering Soil Method and Equipment" patent. The important content was withdrawn, and at the same time, the patent for the “method for the production of alkaline residue†at the Tianjin Soda Plant was also authorized, but some of the derivative technologies based on this technology have become irreversible. At the end of May 2005, the court finally sentenced the plaintiff's Saline Real Estate Development Co., Ltd. to lose.
The case is thought-provoking: The Tianjin Soda Plant, which has been conducting research on the treatment of alkali residue for many years, will not only avoid lawsuits if it is effectively protected, but it may also have ownership of all derived technologies based on this technology. interest. This shows that companies must pay attention to the protection of intellectual property rights, otherwise the loss is inestimable.
Obviously his own technology but let others sue to the court --- Tiancao hit a lawsuit should not fight
A passive lawsuit, an undisputed waste residue treatment technology, after five years of court litigation, eight years of trial of patent disputes by the State Intellectual Property Office, finally came to an end in May this year: the defendant Tianjin Soda Factory was finally easy Won.
