The Patent Portfolio Research Of Air Purification Technology

Air purification technology is to solve the problem of indoor air pollution. As the demand for air purification products increases urgently, the domestic air purifier market has entered a stage of rapid development. For foreign companies entered into the field of air purification very early, they have done deep research of the air purification technology and also applied a lot number of patents in the main consuming countries. From now on, only a few patent dispute happened in Chinese air purification market. However, domestic enterprises must do a good study of patent information analysis about air purification technology to avoid patent dispute in the future.The patent information analysis of foreign air purification technology shows that foreign air purifier market has entered a mature stage. Japan, South Korea and America are the major patent application nation of air purification technology. These three countries occupied the most of the total application. The important patent applicants are almost from the three countries. The patent information analysis of the foreign key enterprises Panasonic, Daikin and Samsung shows that they all attach great importance to the domestic market and give consideration to other regions of the world at the same time. They all have a very comprehensive coverage of air purification technology. However, the Panasonic Corp’s technical strength is stronger and The Samsung Corp’s market capacity is stronger.The patent information analysis of Chinese air purification technology shows that China’s air purification market has entered a stage of rapid development. China has a large amount of patent application but the patent applicant is very fragmented. Patent information analysis of domestic enterprises Gree and Haier show that they enter the field of air purification is not for a long time and began to apply for patent actively In recent years. They have a small number of patents and the coverage of technology is very narrow. Compared with foreign enterprises, domestic enterprises do not have the advantage in the number of patents and technology level.At present, foreign enterprises have about 80% of Chinese air purification market share and they have superior in technology and brand. Faced with this situation, from the perspective of enterprises, domestic enterprises should take the initiative to accept the challenge, actively carry out technical research and pay attention to the patent application in order to improve technology coverage and area coverage of their patents. When it is necessary, they can consider buying patents or seeking research and development partners. From the perspective of industry, domestic enterprises can consider the establishment of industry alliance. The industry alliance themselves can set up their own patent pool to help them improve the ability of patent management and the overall competitiveness of enterprises. That will be good for them to deal with the strong competition pressure from foreign enterprises. The state can provide funding and policy support in the aspect of industry.
