1. background: technological innovation level and policy support of enterprises. Enterprises in the target country have a high level of technological research and development, and the government has also introduced policies to encourage technological innovation, which requires strengthening the protection of their own technological achievements in the market, setting up patent barriers and preventing the entry of similar foreign products.
2. Purpose: To protect domestic industries and obtain excess profits. Setting up patent barriers can make domestic similar products have technological monopoly for a certain period of time, protect the development of domestic industries, and at the same time obtain excess profits by virtue of technological advantages. This is also the goal of the government of the target country to support the national industrial policy.

In fact, setting too high or abusing patent barriers also belongs to trade protectionism, which invisibly hinders the fair competition of products from other countries, affects the global trade situation and is not conducive to long-term economic development.
