2. The technical solutions involved in the standard may have patent protection. When implementing according to the standard, for example, when using the methods in the standard or manufacturing the products in the standard, we need to pay attention to the possibility of patent infringement. We should know in advance whether these technical solutions have applied for patents, and if so, what legal status they are in at present.
3. At present, there is still controversy about whether the standard literature itself enjoys copyright. The mainstream opinion is that the standard itself does not enjoy copyright (except enterprise standards), and the publishing license of the standard is an administrative act of the state, not the exercise of copyright in civil law.
