A Study On The Patent Tactics Of Chinese4G Mobile Communication

The fourth generation of mobile communication technology is a hot topic in thefield of communications, the direction of the key mobile communication technologydetermines the future of the industry. For the high-tech industry, the patentinformation contains a huge value, patent tactics is an important part of propertytactics. In2G and3G era, intellectual property awareness of Chinese enterprises is notstrong, and many multinational companies with its own strong scientific andtechnological strength to achieve a massive accumulation of patents covering inChina.so,many Chinese telecommunications companies in the passive situationwhere inability to break through. With the advent of the4G era, the domesticmanufacturers have realized the importance of patents. Therefore, it is necessary toidentificate the fourth generation of mobile communication technologies, and to studythe distribution of patents in key technology areas and major strategic layout of thepatent applicant. Intellectual property rights, especially patents have become theimportant strategic weapon to improve the key competitiveness.This article will ues the fourth generation of mobile communication technologyto be a study object， based on the patent information，make a empirical research forthe global patent information of Fourth-generation mobile communicationtechnology． Then collate the results of research， make a comparative studybeteween it and Chinese4G mobile communications， summarize the differencesbetween the two strategies． Finally， making a analysis and mining， on the leadingapplicant，in order to provide useful information and reference for the development offourth-generation mobile communications in China．The study found:First, the fourth generation of mobile communication technology has a a fiercepatent portfolio in worldwide; the United States and China are two of the most majormarkets, followed by Japan, Korea and Europe;Second, in the field of4G, the United States and China has become the mostpowerful rival for each other; China has the advantage in the number of patents, butthe United States far more than China on patent quality; and the development ofbranches communication technology of U.S. are balance, and, the U.S has a largemultinational representatives; while the number of Chinese need to be improved, andthe strength of enterprises polarization evident; Third, the large multinational mobile communications all have strong patentrepository, not only has the advantage in the number of patents,but also in the quality;they are committed to the transformation of the patent innovations, to safeguard theirown interests, at the same time, the patented technology use into standard techniquesto obtain greater benefits. and but also to safeguard their own interests the patentedtechnology into standard techniques to obtain greater benefits. Also, they useself-developed applications, foreign acquisitions, cross-licensing of patents and othermeans to effectively operates,which worth we learning from.
