There are three ways of patent retrieval: paper retrieval, software retrieval and online retrieval. (1) Paper carrier is the main form of patent literature and the main object of retrieval. The materials searched by paper retrieval are generally the least error-prone and the most evidential. However, in the process of patent retrieval, it is inefficient, time-consuming, easy to be lost and damaged, and it is difficult to retrieve the latest information because of the long printing and distribution cycle. (2) Software retrieval usually includes microfilm, computer magnetic media and CD-ROM patent literature retrieval. Microfilm patent literature has developed rapidly because of its small space, high storage density, long preservation time and easy copying. It has become one of the main means to store the full text of patents.
