Intellectual property is an important feature of knowledge economy. At present, the importance of intellectual property rights is increasingly prominent, and together with trade in goods and services, it constitutes the three pillars of the World Trade Organization (WTO).
Since 1980s, global technology trade has developed vigorously, and the transfer of intellectual property trade has increased substantially, much faster than the trade of tangible goods, and the trade of tangible goods involves more and more patents, trademarks, trade secrets and copyrights. According to the statistics of the World Intellectual Property Organization (WIPO), the trade volume of licensing trade mainly based on patented technology between countries was $2 billion in 1965, 1 100 billion in 1975 and $50 billion in 1985. The growth rate of technology trade greatly exceeded the growth rate of general commodity trade in the same period. In the foreign trade of some countries, the proportion of intellectual property trade such as patents is increasing. Take the United States as an example In 1950s, the dependence of its export commodities on intellectual property rights was only 10%. In the 1990s, this figure rose rapidly to 50%, and now it has reached 65%. From 65438 to 0999, the foreign trade deficit of the United States was $267.6 billion, but its intellectual property trade not only had a surplus of $25 billion, but also its exports exceeded traditional export products such as airplanes, reaching $37 billion.
