Trademark, patent and copyright are three different forms of intellectual property rights, which are used to protect different types of creation and innovation. The main differences between them are as follows:

Trademark:

A trademark is a logo used to distinguish the source of a specific commodity or service, which can be graphics, characters, combinations of graphics and characters, etc. The main purpose of trademarks is to protect the interests of corporate brands and consumers, and to ensure that consumers can identify and distinguish different goods or services. Trademark right protects the exclusive right to use a trademark, so that the holder of a registered trademark can prevent others from using the same or similar trademark on the same or similar goods or services and avoid confusion and misleading.

Patents:

Patent is the exclusive right to protect invention and creation, which can be the novelty of products, methods and processes and the non-obvious technological innovation. The main purpose of patent is to encourage innovation and technological progress and protect the rights and interests of inventors. By obtaining a patent, the inventor can exclusively use, manufacture, sell and authorize others to use his invention within a certain period of time. The patent right protects the technical scheme of the invention and prevents others from using the technology without permission within the validity period of the patent right.

Copyright:

Copyright is the right to protect original works, including literature, art, music, movies and software creation. Copyright protects specific forms of expression, not the concept of creativity itself. It gives the copyright owner the exclusive right to use his works, including the right to copy, distribute, display, perform and modify. The main purpose of copyright is to protect the author's creative achievements and encourage the spread of creation and cultural creativity.

To sum up, trademarks mainly protect business marks, patents protect technological innovations and inventions, and copyrights protect literature, art and creative works. Each form of intellectual property rights has its unique protection object and purpose to promote innovation and development in different fields.
