Intellectual property law is a legal system that protects intangible property rights such as intellectual property and commercial logos, mainly including the following categories:

1. Copyright Law: protects the copyright of authors of literary, artistic, and scientific works, as well as the rights and interests related to copyright. Copyright covers both personal and property rights, such as publication rights, attribution rights, reproduction rights, distribution rights, etc.

2. Patent Law: aims to protect inventions and creations, including inventions, utility models, and designs. The patentee enjoys exclusive implementation rights, and without permission, others are not allowed to manufacture, use, offer for sale, sell, or import their patented products for production and business purposes.

3. Trademark Law: Protecting trademark exclusive rights and ensuring that trademarks can distinguish the source of goods or services. The trademark owner has the right to prohibit others from using the same or similar trademark on the same or similar goods.

4. Anti Unfair Competition Law: Some of its provisions involve intellectual property protection, such as protecting trade secrets. Trade secrets refer to technical information, business information, and other commercial information that is not known to the public, has commercial value, and has been protected by corresponding confidentiality measures taken by the rights holder.

These laws together constitute the intellectual property protection system, safeguarding the legitimate rights and interests of rights holders, and promoting innovation and cultural development.
