Taking skin cleaning patents as an example ， this paper has conducted the patent assignee co-citation analysis by drawing hierarchical cluster map and patent assignee map ， revealing the following conclusions ： patents mainly distribute among three fields ， chemical-engineering industry oriented field ， cosmetics oriented field and chemical-cosmetics field ， with the last one as the core patent field ； all patent assignees are corporations ， mainly distribut- ing in European-American and Japanese districts ， of which the former has advantage in chemical-en- gineering industry and nondurable consumer goods and the latter has many corporations engaging in cosmetics RD. It is also convinced that this approach is feasible in exploring the technological inno- vation situation of enterprises.
