Each country’s intellectual property system is roughly the same, but there are some differences based on the country’s history, culture, and customs.
First of all, when joining the WTO, there are requirements for intellectual property laws, which must meet the most basic requirements agreed by various countries, and the rest should be adjusted according to the circumstances of each country. For example, pornographic publications are protected by copyright in many countries. But according to our country's history, tradition, and current laws, pornographic publications are illegal and will not receive protection.
As international trade develops and becomes more frequent, FTA (Free Trade Agreement) appears. FTA, as the name suggests, is about realizing "intimate and seamless" commercial transactions between two or more countries. In order to facilitate trade, many legal aspects must be fully understood, among which intellectual property law "bears the brunt" because, national Countries attach great importance to intellectual property rights and require that this aspect be roughly consistent with the intellectual property laws of the host country.
Nowadays, many products are inseparable from intellectual property laws. Patents, copyrights, etc., often become the basis for businesses to survive.
Based on the above, intellectual property law, now, will also consider international issues in legislation.
