A：Issued by the State Copyright Administration of the people's Republic of China and enjoying the protection of intellectual property in the mainland, it is an important ownership certificate of intangible intellectual property.

A：The Copyright Office has only one version, that is, the paper version; However, with the various reasons of information security, the PDF files that have been digitally signed are more significant in the times, which can not be PS, forged or verified by signature. So we have this e-copyright certificate service launched by a third-party company, and we cooperate with Android App Store (it seems that the e-version is easier to pass the market audit).
