How are integrated circuit layout designs protected in China, and how does this differ from copyright or patents?

China has a dedicated exclusive-right regime for layout designs of integrated circuits, under the Regulations on the Protection of Layout Designs of Integrated Circuits.

Three differences set this right apart. First, how the right arises: an exclusive right in a layout design comes into existence only on registration, unlike copyright, which arises automatically on creation. Second, how it is examined: registration involves no substantive examination of originality. Third, what is protected: the right covers the three-dimensional configuration of two or more elements, at least one of which is active, together with some or all of the interconnections in an integrated circuit, or such a configuration prepared for the manufacture of an integrated circuit. An invention patent, by contrast, protects a technical solution.

Protection lasts 10 years, running from whichever is earlier: the date of the registration application, or the date the design was first commercially exploited anywhere in the world. Whether or not it is registered or commercially exploited, a layout design ceases to be protected 15 years after its creation.
