属地管辖原则，Territorial Principle

The Territorial Principle is a legal doctrine that asserts a country's laws apply only within its territorial boundaries. It is a fundamental principle of international law and jurisdiction, particularly in criminal law, taxation, and intellectual property.

Key Aspects:

1. Jurisdictional Limitation – A state can only enforce its laws within its own borders.

2. Criminal Law – Crimes committed within a country’s territory are subject to its legal system, regardless of the nationality of the perpetrator.

3. Taxation – Many countries tax income generated within their borders, even if the taxpayer is a foreign entity.

4. Intellectual Property – Patents, copyrights, and trademarks are typically enforced within the country where they are registered.

5. Diplomatic Exceptions – Certain individuals, such as diplomats, may have immunity under international treaties.
