In patent invalidity and patent litigation procedures, it is often inevitable to involve the Internet retrieval and use of existing technical evidence. However, due to the special restrictions on Internet access in China, many overseas evidences found on the Internet can only be completed with the help of "climbing over the wall", so it is impossible to notarize evidence at the legal level in China and use it for patent invalidity and litigation.
The notarization of such existing technical evidence can be completed by a Chinese authorized notary in Hong Kong.
Our rights protection team has handled the notarization of many evidences involving the invalidity of Chinese invention patents and Chinese appearance patents.
