Intellectual property protection has become the strategic commanding height of the international economic order and one of the focuses of fierce competition among countries. First, with the rapid development of science and technology, the traditional intellectual property system is facing challenges, and the scope of intellectual property protection is constantly expanding. For example, in the patent field, the United States gives patent protection to inventions such as computer-readable carriers containing computer programs, genetic engineering and business models on the Internet. The space for technological innovation in developing countries has been greatly suppressed. How to determine the scope of patent protection scientifically and reasonably has become an urgent and meaningful research topic. In the report released at the end of 1998, the World Bank pointed out: "The increasingly strengthened international intellectual property protection legislation is in danger of widening the intellectual property gap between developed and developing countries." Second, in recent years, some developed countries have vigorously promoted the internationalization of patent examination, and proposed to break the geographical restrictions of patent examination and establish a "world patent", that is, a few countries are responsible for patent examination and grant patents, and other countries recognize the examination results. The so-called "world patent" is essentially the patent examination work of all countries in the world, which is carried out by the patent offices of a few developed countries and regions such as the United States, Japan and Europe. Third, intellectual property rights are included in the jurisdiction of the World Trade Organization. Intellectual property, with equal emphasis on trade in goods and services, has become the three pillars of the World Trade Organization, and the rules of trade in goods and dispute settlement mechanism have been introduced into the field of intellectual property. According to the regulations of the WTO, any member of the WTO will be subject to cross retaliation in trade because of poor protection of intellectual property rights. Intellectual property rights have become the frontier of international trade. With the gradual reduction and cancellation of tariffs, the status and importance of intellectual property protection in international trade will become more prominent. Fourthly, the developed countries such as the United States and Japan have adjusted and formulated the intellectual property strategy facing the new century and incorporated it into the overall strategy of national economic and technological development.
