According to Article 59 of the Chinese Patent Law the specification and drawings related to a patent right may be used in claim construction. However, it has long been a question as to whether claims are to be construed based on claim language alone without referring to the specification and drawings, or whether the content of the specification and drawings shall be read to limit or otherwise be used to illustrate the scope of claims. In a recently decided case (number 2016-XingZai-70), the Supreme Court of China held that the content of the specification and drawings was not allowed to be read into the claims, and that claims were to be construed in a narrow sense.
