The difference between a defense representative and a defended representative lies in their different meanings.

1. The representative works of defense are articles, including professional papers, monographs, invention patents, technical reports, design documents, technical standards, industrial construction methods, technology transfer and transformation service contracts, etc.

2. The defense representative's explanation is the interpretation of the article. It is to choose a professional paper as the respondent, and it is not necessary to provide the explanation of the respondent. Other defense representatives are required to provide explanations of defense representatives.
