When construing the patent claims to determine patent infringement in China, the principle of equivalence will be applied, that is, the protection scope of a patent right is not only determined by the technical features recorded in the claims but may also be determined by equivalent features. Therefore, the protection scope may be wider than the scope of the written claims when determining the protection scope of the claims in China.
